Who Else Would Advocate Extreme Measures to Protect Homeland?

How do I protect myself from the city water in my new apartment?Ever heard about FLINT ( Michigan ) WATER CRISIS ? Here is a latest link if not :Flint is facing a Shigellosis outbreakUnfortunately there's NOTHING that you or anyone can do in personal level , except from drinking it of course . The water will find a way in your apartment through the pipes . You will need to shower or wash dishes and your clothes sooner or later . On the other side , things are not that bad as you seem you think . Paranoia is never a good ally , so it all depends of where exactly you live and what kind of PIPES your building has already installed . If you live in FLINT MICHIGAN I have bad news for you . ALSO if you live in areas that OIL FRACKING is permitted , like FLORESVILLE near SAN ANTONIO TEXAS or Williston North Dakota then you are also in deep trouble . It's been reported that oil residue in water is in high levels . CNN released a video that residents can actually light up a glass of water , yes just like that fancy bartender that can set your alcoholic beverage on fire in the club . Unfortunately OIL in your water is not the same as your tequila shot on fire . So do your research , where EXACTLY do you live ? Avoid all OIL FRACKING AREAS to begin with , also try to stay away from areas that store NUCLEAR TOXIC WASTE . Stay away from Arizona from example and TEXAS , FLINT Michigan is unrelated to FRACKING , it's older and cheaper water PIPES . So you can be living in the country and having the delusion that you are safe but if it's TEXAS that is too loose on what chemicals are legal then you are in a big trouble . Example : San Antonio TEXAS has no problem with allowing the use ASBESTOS .. that's insanely dangerous . California on the other hand is way safer , way more conscious about chemicals that are allowed in construction . So here is the problem : it's NOT THE WATER as they told you that is dangerous , it's the PIPES in your home/ town / city / area . Lobbyists never cared about public health , lobbyists only care about PROFIT . Plz stay away from Asbestos , chemicals ,OIL FRACKING AREAS , FLINT , TEXAS and list getting bigger and bigger . Research all you can , and try to move and live in "greener" areas , places that the protection of the environment is important and a major priority .. you need to live in areas / cities / states WITH THE HIGHEST SAFETY STANDARDS POSSIBLE ... good luck , and once again , no it's NOT the water itself . NYC for example is way SAFER than the country , especially in heavily industrialized SOUTH . As I said , TEXAS is a big no no . Cancerous with low standards , OIL driven economy states are the first RED FLAG to look for— — — — — —How much of an impact does tapping into city water have on potential buyers?so glad I did not buy this lemon of yours— — — — — —Is is safe for me to do this?If everyone is ordered to boil water, that includes restaurants. If the water is piped in through the city, then they would have to boil it before putting it in the soda machine. I do believe that McD's does not use city water though. Just ask at the drive through to make sure— — — — — —Does the city water dept change your water pressure?check your flapper valve in your toilet it sounds like it is leaking mine was doing this and the only way i knew it was is a heard water running just a trickle of it in the drain pipe under my toilet in the basement— — — — — —When I clean my fish tank I use this water straight from the tap! Im getting this dechlorinater from petsmart.The package will have instructions that are easy to follow for dosage of the Dechlorinator. It is just my opinion, but I use dechlorinator because I have city water that contains chlorine and chloramines which are toxic to fish and I always allow the mixture time to work. When I make up a fresh bach of water, I put in the reccomended dosage (from the label or package) with my tap water and allow it to sit in a bucket with an air stone for 24 hours. The air stone is for the purpose of mixing the chemical through the water and to aid in gas exchange (allowing the bad stuff to escape from the water). It also helps the pH of the water to stabalize. I would never fill an aquarium with water, dump in dechlorinator and just throw fish into the water.

None You can use small pieces of carpet to put under furniture, though the carpet may not match and will probably fray over time. None Make sure the flooring is properly prepared and installed. Improperly installed flooring can result in more damage than usual. None It's important to keep a regular cleaning schedule for your floor because many manufacturers stipulate in the warranty plan that regular cleaning must be done for warranty to be upheld.2. What to do about fleas?I too get plagued by fleas!!

There is currently no opt-out for the carrier approval processes, and the only way to get direct updates is to re-flash your device with country-variant firmware.This functionality was widely rumoured (and Microsoft even alluded to it) but it did not make the cut. Possibly in 8.1?1. should we name the next aircraft carrier the Constitution,or something American?Constitution is already taken. Old Ironsides is STILL listed as being an active Vessel. she even gets underway twice a year and actual Active Duty Sailors are assigned to her permanently2. Can a Super Stallion lift an aircraft carrier?I vaguely remember back to the mid 1970's that the US Navy used two RH-53D's to tow an LPH just to see if they could. I saw this picture decades ago, and have never been able to find it again. Does anyone in Quoraland know anything about this?.3. Why USA obsessed with expensive Aircraft Carrier and Sub?Navies RN USN Canadian at the end of WW2 the RN was still the biggest until 1972 when the British closed down all kits bases East of Suez4.

HomePlug AV only uses 917 of 1155 sub-carriers so each sub-band is like an audio FM channel that is equalized flat in that band with 4, 8 or 16 bps/Hz or so in each sub-carrier. The beauty of DSP power is to FFT and equalize so each small sub-band has a flat response. The latest standard supports 200 Mbps over home power lines. ADSL and cable modems use a similar ODFM method, but much larger sub-bands.So it's just a fancy RF Modem6. No sim card inserted, can I get a phone carrier?You can check the IMEI online and you will be able to find out what carrier it's locked to7. what carrier is best while in Mexico?I used Sprint while traveling in Mexico and had absolutely no problems with the service.

I had a blue cover and wanted to change it but the prices were outrageous!! I searched and searched and ended up just keeping it blue, it really does not matter12. question about in-flight pet carrier?I've always heard the rule is that it must fit under the seat. If it will squish down, I would think that would work. But your best bet is to call the airline you will be flying with and ask them specifically. You would hate to get to the airport and find out that the carrier is not acceptable13. Can sailors feel a jet landing on an aircraft carrier?If you are on the O-3 level, the deck directly underneath the flight deck, you can definitely feel and hear it. Spaces underneath the Landing Area (LA) get very loud, to the point that some sailors working there need hearing protection. The spaces shake when a plane's on one of the catapults and goes to full power. The O-3 is also where most of the Air Wing's living and working spaces are, on the presumption that if flight ops are going on, they are all up and about14. Which baby carrier is your favorite?I particularly have heard stable issues approximately the two the maya wrap and the bjorn provider. I want my ring sling, it is versatile and straight forward to apply, plus that's a delicate fabrics that is not get us all warm and sweaty because of the fact we live in FL.

I am pretty sure you can get a tarpaulin or plastic equivalent cover from most motor factors1. Do soldering glasses protect eyes from capacitor explosionIf you are working with that sort of stuff and anticipate trouble you may wish to get chemical rated safety glasses eg. ANSI Z87.1-2010 with D3 splash protection. These have side shields as well. In some cases (very high power circuits) full face shield protection (or arc flash suits) may be called for. This would be somewhat of an extreme precaution for wiring up a typical solderless breadboard with 555s. It's impossible for us to really tell what your situation is. Unanticipated venting and explosions are very rare occurrences in most conditions. If you are working with (say) 5V DC circuits, it is exceedingly unlikely anything potentially harmful would happen unless you are doing something really silly like peering at a reversed capacitor from inches away.2. How do carports protect against frost?It has to do with radiational cooling. Cars radiate their stored heat fairly efficiently and cool off. If there is sufficient water vapor in the air, it can form frost on the cold surface. The carports act to intercept that radiated heat energy, absorb and re-radiating some of it back downward, which in turn does not allow the car surface to cool as much as it would otherwise if it was out in the open.3. How can i protect my feet?its because flats dont give any support get orthodontics they sell them at drug stores or go to orthopedic and get ones made for you (make sure to get ones that you can put in all shoes not just sneakers) your health insurance may cover them so all you would pay for is the co pay4.

Bhagavad Gita Chapter 3, Verse 9 says - yajnarthAt karmano-nyatra lokOyam karma-bandhanAh tadArtham karma kauntEya mukta-sangAh samAcaraMeaning: Work done should be done as a as a sacrifice for God, otherwise work binds one to this material world. Therefore, O son of Kunti, perform your prescribed duties for God's satisfaction, and in that way you will always remain unattached and free from bondage.Regarding your actions in your example, Bhagavad Gita Chapter 3, verse 5 says - nahi kaschchit khaam api jAtu tihhatyakarma-kit kAryate hyavascha karma sarvA prakitIjair guaiMeaning: All men are forced to act helplessly according to the impulses born of the modes of material nature; therefore no one can refrain from doing something, not even for a moment.6. How to protect your cat in a tornado emergency?Buy a medium sized carrier, one that will hold both cats comfortably, that you can easily carry around. If tornado, take the cats wherever you go for shelter. Where to seek shelter in your home: Ideally if you have an interior room which has no windows and is not adjacent to an outer wall. In most cases this would be a closet. If closet is the only good shelter you have make sure to keep it cleaned out and prepared for an emergency during tornado season. If you do not have a safe room, then you can lie down in a bathtub. Use couch cushions, or a small bed to pull over your heads for cover. If you have access to get under some sturdy stairs, this is also a good kind of place to be, especially in a multi-story building. Stairs are usually built to a higher standard and can hold more weight, so it likely will withstand major structural damage.7. How to write protect a USB key?There are pendrives on the market (just like SD cards) which have this little button/switch on them that allows you to turn read only/write on and off. It seems to be the only solution on your case. There are many pendrives with it and I am sure you can find one that suites your needs. This site has a list of devices with hardware write protection.For example:

It depends what you mean by training. Most every dog has a natural instinct to do some form of protection or alarm for those they love or who are in their care such as the babies to a mom dog. A case in point was our Greyhound. Years ago, my big Greyhound and my toy poodle and I were taking a walk on lead minding our own business and somebody's dog jumped out at us from their vehicle that was driving by. I lost my balance and began to fall to the ground, meanwhile my Greyhound in lightning speed had that dog pinned under his front paw. By the time I hit the ground and looked up that wild flying dog was under the control and watchful eye and paw of my Greyhound. To my dismay, the driver of the car only came and got their dog with no apology, threw their dog in the car and drove off. Some joggers who were passing by and had seen the whole thing helped me up. My Greyhound did not harm anyone but had saved us from harm. I suspect a well-behaved and well-trained dog of any sort would do the same. That could indeed include a German Shepherd. Just because German shepherds have been known to be trained as attack dogs or defense dogs does not mean you have to do that training. But you do have to have training with the dog for basic obedience and commands and a very good idea is to at least have them at the level of Canine Good Citizen from the AKC test whether you take the test or not. This will ensure you have a safe dog to take wherever you are going and at home. 1. What hiking boots will protect my ankles?One of the ideas behind hiking boots is that they afford more ankle protection and foot protection than regular street shoes or running shoes. Some of that support is simply a product of the design-firm soles offer greater stability and prevent the foot from "rolling over" into a sprain. But most hiking boots also use a tall design and heavy leather material to keep ankles aligned and upright, even on rough trails. That's well and good, but only if you have healthy ankles. My right ankle, however, has seen better days. A long-ago sports injury (it was close to a third-degree sprain-I still can hear the ligament tearing) now haunts me on a regular basis. And if you have an unstable ankle, no boot on earth is going to save you if the foot starts to roll over. Even big plastic mountaineering boots. So I opt for extra support in the form of an ankle brace. There are several models out there, but I wear an Aso brace. They do not just "support" the ankle like an elastic wrap, they pretty much lock it in place. The Aso is built with an inner section that laces up is covered by two ballistic-nylon straps that wrap around the ankle and tie down with hook-and-loop closures. It goes for $30 and fits into any shoe. Not everyone should go this route. Indeed, most people do not require it. But if you have troublesome ankles that roll over and sprain easily, get a brace. I've never re-injured my ankle when wearing an ankle brace, but without one it happens regularly. And I still recommend that people with healthy ankles wear real boots-over-the-ankle, leather boots-because they will help prevent injury. A few years ago Lowa experimented with a technology they called Biomex. It looked like a plastic exo-skeleton surrounding and bracing the ankle. I tried a pair and thought they were great. Alas, they proved difficult to manufacture and Lowa dropped the line. Still, Lowa's Renegade ($185) gives you a nice mix of light weight and stability. The Oboz Wind River boots ($165) do, too. And when I left my ankle brace home while hiking in the Grand Canyon last April, my Scarpa Kailashs ($185) held up well. A simple way to make any pair of boots more stable is by swapping out the stock insole for a pair of Superfeet insoles ($39).2. Could a helmet protect a grenade?if you can handle the impact of the explosion and still keep the helmet over a frag grenade, then technically yes. frags shoot small sharp projectiles designed to seriously maim an individual. i dont know why you would try this technique though.3. Do weightlifting belts protect the lower back?A weight lifting belt facilitates shelter the mid/decrease section, back and abdomen muscle tissues. i could purchase a belt to apply and see if that facilitates. If soreness pursists you will be able to desire to seek for a doctor earlier you do extreme injury and destroy your education. The well-being midsection could have belts besides, ask

unplug your rca jacks then turn your head unit on and see if the protect light is still lit, turn your head unit off and remove your speaker wires from the output and turn the unit back on and check the protect light , do one at a time to narrow down any possible bad connections or shorts, if the protect light comes on regardless it is probably time for a new amp1. What to use to cover/protect carpet in room?You and the chinchillas may have a better time of things if they lived in the basement rather then devoting a room to them. It's cooler they hate heat mostly they are nocturnal. They like to fling their poop and bedding too...very messy.2. If Christians wanted to protect the sanctity of marriage, shouldn't they start with divorce?They have NO argument as to why same-sex marriage should not legal. Using their own Bible, divorce and adultery would be punishable by death and polygamy would be the norm. notice how we do not do that? they love to pick and choose which parts of the Bible to follow and which parts to ignore. >> If they did really care about tradition in marriage then would still let their parents pick husbans/wife for a financial gain and they would not let little things like child protection laws stop 50 year olds from marrying 8 year olds. WE ALREADY HAVE CHANGED THE DEFINITION OF MARRIAGE, WAKE UP.3. Whats the best way to protect a palm tree in winter?most horticultural fleece is white. aka the sun can get through. i wrap fleece around them then stuff hay into the top. Palms grow from the center out. if you look into the centre of were the leaves are you will find a tight cluster of leaves which have not opened yet. we call this the heart. you must keep this protected. if water gets in here in the winter it will freeze and rot the heart. if your palm is in a pot it would be a good idea to raise it off the ground either with pot feet or a polystyrene plant tray.4. How to create a container that will protect an egg?I've done this twice now and always wanted to try this idea. Take Caprisun containers (or any like it, the ones that are foil and blow up) and make a holder for the egg with 3-5 of them. Before dropping the egg, blow up all of the containers with the provided straw. When the containers hit the ground, the air inside will be expelled, and the egg will be protected. If you are being graded on size and or/ mass, I believe this design could win. But, keep in mind I have never tried this, so you should do some testing before going into it full force.5. how do squids protect themselves?they project ink then they swim away6. Can I protect my face from grease?Would not a waterproof sunblock work?7. How do I protect small objects?You have conflicting needs: For useful fire protection, something like an inexpensive (20) fire safe that "withstands temperatures up to 1550 for up to 30 minutes" would be needed, but that makes its contents seem more valuable to thieves. Any safe that would also deter thieves (200) would be an order of magnitude more costly, but if it's movable, a determined thief could take it. (Thieves even will pull apart walls to strip copper wire and pipe. )The transparency requirement is incompatible with fire protection because heat transmitted by radiation would destroy the contents. You could put a photo of the objects on the container, though. However, if transparency is of prime importance, you could seal the object(s) in fused quartz or, better, sapphire (fused aluminium oxide). So pick the most important criteria to you and select something that fits8. Should we do more to protect the rights of sex robots?I think we should do more to protect the rights of washing machines with uneven loads. They should all have the notice do not sit on me emblazoned on them with an emergency number in case they are sat upon9. Why do Turkish forces not protect Idlib in Syria?Why are Turkish forces in Idlib at all? They should never have invaded.Hopefully they will be bundled out - with heavy casualties - when Assad, the Iranians and the Russians retake it from the rebels.Why do Turkish forces not protect Idlib in Syria?.

For an essential guide to the city,sign up for How to Boston,Boston.com’s weekly culture and lifestyle newsletter.There are two kinds of plant owners in this world: those who remember when to water their plants, and those who buy succulents. Of course, being a good plant owner is about more than regularly sprinkling your plants with H20 or even resoiling them. It’s important to be thoughtful and honest about your office or living space before you go to the greenhouse to pick up some new leafy occupants: How much sunlight do you have to work with? Are you shopping for an indoor or outdoor space? How much maintenance can you realistically commit to? Lindsey Swett, owner of Niche Urban Garden Supply in Boston and Cambridge, helps locals answer these questions so that they can head home with plants that will live long lives and prosper. Take a good look at the space around you, and read her suggestions before you invest in new potted friends.When a patron comes in and asks for a low-maintenance plant, Swett usually points them toward the drought-tolerant ones. “The snake plant or a ZZ plant would be good options in this case,” Swett said. Snake plants generally have yellow or white striped leaves, while ZZ plants have dark, waxy leaves that have a plastic-like appearance.“Even a pothos plant could work,” she continued, referencing the common houseplant with wide, golden-yellow leaves, “although with those you might need to check in a little more regularly than the other two.” All three of the aforementioned plant types are also great for new apartment renters who signed leases for spaces that looked a whole lot sunnier on Craigslist. Swett said that drought-tolerant plants also tend to do very well in low-light situations.Sometimes all of the chew toys or the litter boxes are a dead giveaway that your apartment completely revolves around your furry best friend. It’s important to make sure that your pet’s home isn’t suddenly invaded by the addition of a new plant that might be toxic to him or her. Swett said that customers who own pets are usually very mindful of this priority, and she suggested the safe peperomia plants, which have wrinkled or streaky leaves and are often called “radiator plants.”Succulents are also a good bet, she said, but in general, Swett said she’ll run any plant by the ASPCA’s guideline list in the store before recommending it to a pet owner. Swett nudges pet owners away from anything in the ficus group or the euphorbia group because those tend to be more toxic when accidentally consumed. It’s important to remember that not all outdoor spaces are created equally from a plant’s point of view. “If you have a shady patio, you’re going to want to go with a perennial that’s suited for low light and high water content in the soil,” Swett said. She suggested a no-brainer shade plant like a heuchera, which is most easily spotted by its bell-shaped flowers.For a roof deck, she recommended perennial grasses because they’ve been adapted or commercialized from prairie species. These grasses have deep roots that won’t be impacted by wind that is common on rooftops and might otherwise dry out the upper layers of soil. This time of year —or, “once nighttime temps are in the upper 50s consistently and there’s no threat of frost,” according to Swett —is also a good time to think about taking plants you already own outside. Some common indoor plants that especially love to move outdoors about now include alocasias, citrus, Boston fern, and flowering plants like orchids and jasmine, said Swett, who reminds people to protect plants from intense heat and light. “Morning sun and afternoon shade is the ideal scenario,” she said. While all of that hauling back and forth might seem like a lot of work, Swett said it’s a great way to appreciate your plants and the warm weather. “I love the ritual of moving my plants outdoors when it gets warmer out, and the reverse in the fall,” she said. “Invest a little more time in fertilizing and enjoying your plants over the next few months –– it’s their high-growth season.”

Childproofing Your Home- 12 Safety Devices To Protect Your ChildrenEach year, children are injured by hazards in and around the home. The good news is that the risk of injury can be reduced or prevented by using child-safety devices and reminding older children in the house to re-secure safety devices after disabling them. Most of these safety devices are easy to find and are relatively inexpensive. You can buy them at hardware stores, baby equipment shops, supermarkets, drug stores, home improvement stores, on the Internet and through mail order catalogs. Safety devices should be sturdy enough to hinder access and yet easy for you to use. To be effective, they must be properly installed. Follow installation instructions carefully. Remember, too, that no device is completely childproof; determined youngsters have been known to overcome or disable them. Here are some child safety devices that can help reduce injuries to young children. The red numbers correspond to those on the image following the text. • Use Safety Latches and Locks for cabinets and drawers in kitchens, bathrooms, and other areas to help prevent poisonings and other injuries. Safety latches and locks on cabinets and drawers can help prevent children from gaining access to medicines, household cleaners, matches, or cigarette lighters, as well as knives and other sharp objects. Even products with child-resistant packaging should be locked away and kept out of reach. This packaging is not childproof. Look for safety latches and locks that adults can easily install and use, but are sturdy enough to withstand pulls and tugs from children. • Use Safety Gates to help prevent falls down stairs and to keep children from entering rooms and other areas with possible dangers. Look for safety gates that children cannot dislodge easily, but that adults can open and close without difficulty. For the top of stairs, only use gates that screw to the wall. Use safety gates that meet current safety standards. Replace older safety gates that have "V" shapes that are large enough to entrap a child's head and neck. • Use Door Knob Covers and Door Locks to help prevent children from entering rooms and other areas with possible dangers. Door knob covers and door locks can help keep children away from places with hazards. Be sure the door knob cover is sturdy, and allows a door to be opened quickly by an adult in case of emergency. • Use Anti-Scald Devices for faucets and shower heads and set your water heater temperature to 120 degrees Fahrenheit to help prevent burns from hot water. Anti-scald devices for regulating water temperature can help reduce the likelihood of burns. • Use Smoke Alarms on every level of your home, inside each bedroom, and outside sleeping areas to alert you to fires. Smoke alarms are essential safety devices for protection against fire deaths and injuries. Check smoke alarms once a month to make sure they are working. Change batteries at least once a year or consider using 10-year batteries for alarms. • Use Window Guards and Safety Netting to help prevent falls from windows, balconies, decks, and landings. Check these safety devices frequently to make sure they are secure and properly installed and maintained. Limit window openings to four inches or less, including the space between the window guard bars. If you have window guards, be sure at least one window in each room can be easily used for escape in a fire. Window screens are not effective for preventing children from falling out of windows. • Use Corner and Edge Bumpers to help prevent injuries from falls against sharp edges of furniture and fireplaces. Be sure to look for bumpers that stay securely on furniture or hearth edges. • Use Outlet Covers and Outlet Plates to help prevent electrocution. Outlet covers and outlet plates can help protect children from electrical shock and possible electrocution. Be sure outlet protectors cannot be easily removed by children and are large enough so that children cannot choke on them. If you are replacing receptacles, use a tamper-resistant type. • Use a Carbon Monoxide (CO) Alarm to help prevent CO poisoning. All consumers should install CO alarms near sleeping areas in their homes. Change batteries at least once a year. • CPSC recommends using Cordless Window Coverings in homes with young children, in order to help prevent strangulation. Children can wrap window covering cords around their necks or can pull cords that are not clearly visible but are accessible and become entangled in the loops. If you have window blinds from 2000 or earlier and you cannot afford new, cordless window coverings, call the Window Covering Safety Council at 800-506-4636 or visit WindowCoverings.org for a free repair kit. Window blinds that have an inner cord (for raising the slats of the blinds) can be pulled by a child and form a potentially deadly loop. Consumers should immediately repair these types of blinds. Consumers should know that WCSC's retrofit kits do not address the dangling pull cord hazard associated with many common window blinds. • Use Anchors to Avoid Furniture and Appliance Tip-Overs. Furniture, TVs and ranges can tip over and crush young children. Deaths and injuries occur when children climb onto, fall against or pull themselves up on television stands, shelves, bookcases, dressers, desks, chests and ranges. For added security, anchor these products to the floor or attach them to a wall. Free standing ranges and stoves should be installed with anti-tip brackets. • Use Layers of Protection with Pools and Spas. A barrier completely surrounding the pool or spa including a 4-foot tall fence with self-closing, self-latching gates is essential. If the house serves as a side of the barrier, doors heading to the pool should have an alarm or the pool should have a power safety cover. Pool alarms can serve as an additional layer of protection. Sliding glass doors, with locks that must be re-secured after each use, are not an effective barrier to pools.

one  introductionPaper corner guards are used for corner reinforcement of packaging cartons, as shown in Figure 1. The paper corner protector is formed by shaping and pressing the yarn tube paper and kraft linerboard by a complete set of corner protector. The two ends are smooth, flat, free of obvious burrs, and perpendicular to each other. Paper corner guards are widely used in the packaging and transportation of electronic and electrical appliances, high-tech products, clubs and other products. Paper corner protection is also called paper channel steel, paper wrapped corner, corner protection plate, corner protection strip, paper angle iron, paper angle strip, corner protection paperboard, edge plate, Corner paper and paper angle steel. The paper corner protector can be used together with winding film, packing belt, paper fumigation free tray, etc. to realize medium and heavy-duty all paper natural degradation and environmental protection packaging. Paper corner protection packaging is an advanced packaging technology in the international logistics industry with simple and convenient operation and strong compression stacking and load-bearing.Figure 1 paper corner guardThe CNC high-speed corner protection machine of a packaging machinery and equipment manufacturer in Shanghai is used to cut corner protection materials of various lengths at high speed. The cutting method of paper corner protection is different from that of flying shear, which belongs to chase shear control. The servo motor moves back and forth, which is consistent with the feeding speed in the synchronization area to complete the shearing and quickly return in reverse. The customer's equipment was originally controlled by ordinary PLC, which can not stably meet the production demand of chasing shear and fixed length cutting control. The main problem is the poor synchronization accuracy during high-speed operation. Based on the equipment requirements, delta provides the electronic cam solution of dvp-20pm00d motion control PLC. After practical application, it fully meets the expected requirements of customers.two  Delta dvp-20pm00d solutionThe high-speed NC angle protector is composed of frame, measuring mechanism, cutter mechanism, belt drive and electric control system, as shown in Figure 2.Figure 2 CNC high speed angle protector2.1 introduction to motion control PLCDelta dvp-20pm00d is a programmable controller with special function of motion control. The biggest feature of dvp-20pm00d is that the PLC host directly provides electronic cam function, or dvp-20pm00d is a PLC with built-in electronic cam function, so some places directly call dvp-20pm00d Delta 20pm motion controller, as shown in Figure 3.The 20pm has two 500KHz inputs and outputs. In the electronic cam function, the x-axis is defined as the slave shaft and the encoder input shaft is the spindle. After the cam table is defined, the slave shaft follows the spindle according to the defined curve. Adopting the high-speed dual CPU structure and using the independent CPU to process the motion control algorithm, we can well realize various motion trajectory control, logic action control, linear / arc interpolation control, etc. the NC High-speed angle protector uses the electronic cam function of 20pm motion controller to solve the above problems of unequal length in high-speed cutting. Main features of 20pm:(1) 20pm is suitable for high-speed, high-precision and highly complex motion control occasions;(2) Multi segment speed execution and interrupt positioning;(3) 64K large capacity, built-in flash memory;(5) Two groups of differential pulse output, with the highest pulse output up to 500KHz;(6) Two groups of hand wheel control;(7) Built in electronic cam function, easy to realize winding, flying shear, chasing shear and other applications;(8) Support PLC Sequential Logic Control and NC control (G code and M code).Figure 3 delta motion controller dvp-20pm00d2.2 solution analysis of high-speed chasing shearOrdinary PLC generally uses high-speed counting and inputs it to the built-in high-speed input point of PLC through the encoder. The high-speed input code is connected with the fixed length pressing wheel to collect the linear speed. The collected pulse frequency is multiplied by a certain speed ratio, and then it is used as the output high-speed pulse to drive the servo to simply synchronize the action speed with the speed ratio of the linear speed of angle protection, At the same time, the encoder value is compared with the preset length value. When it reaches the preset value, such as 650pulse, an interrupt is generated to make the cutter act. In this method, the cutter action always lags behind. Affected by linear speed and PLC operation, the synchronization accuracy is poor, the amount of calculation is large, and the CPU processing time is long. Therefore, there will be problems such as uneven fixed length, which will seriously affect the quality of finished products. In the case of low speed (about 10m speed), it can basically meet the requirements, but when the speed exceeds 20m, it will be different in length, with an error of more than 2mm.20pm has built-in electronic cam function and adopts independent motion processing chip. Through hardware, it can process the motion relationship between master and slave shafts in real time. The synchronous control time of two shafts is less than 0.5ms, so as to ensure the position and speed relationship between main shaft and slave shaft at high speed, solve the problem of different length of high speed, and reach the production speed of 50m at the limit of customer equipment, The error is basically within 0.1mm. The hardware configuration of high-speed chasing shear solution based on 20pm is shown in Table 1.Table 1 hardware configurationThe software setting of electronic cam of high-speed chasing shear solution based on 20pm is shown in Figure 4. The cam (numerical control programming) diagram of chasing shear control is shown to have some changes with the cam diagram of flying shear control. Observe the cam speed relationship diagram. The moving mechanism operates repeatedly, and the feeding speed is consistent with the material in the synchronization area. After cutting, it returns quickly in the reverse direction, and then it is consistent with the material feeding speed in the synchronization area again. Encoder pulse input and PLC pulse output completely correspond to each other according to the track, without PLC program scanning. Therefore, it overcomes the problems of large fixed length error at high speed and frequent overshoot of motor in the past.Figure 4 electronic cam software settingthree  ConclusionThrough the successful application of 20pm in the cutting equipment of high-speed angle protection machine, it can be extended to other occasions similar to chase shear control, such as beverage filling. Its action is the same as that of chase shear, but the mechanism is changed from knife to injection port. By changing different control curves, this work can also be widely used in various motion control with high requirements, such as the cam (numerical control programming) function of 20pm will be used in the continuous filling action of electronic cam spinning frame and packaging machinery in textile machinery, the cross cutting heat sealing action of vertical packaging, the spring reducing machining in metal processing, shear bending, etc.

"War epidemic" is a major event in China and even the world. The war between human and virus without gunsmoke may have started since the birth of mankind, but there are many tools in human Arsenal, including blockchain. The pulse of mutual chain explores the ability of blockchain war "epidemic" from multiple dimensions.During the period of COVID-19, the largest personal information collection in China is being launched. Where do you come from, where do you go, what is your temperature, where do you live... Such fine-grained information, coupled with a population base of 1.4 billion, may be the largest "population survey" ever conducted by mankind.The chaos of personal information collection also appears at the same time, and personal information leakage has become a new problem.On February 9, the office of the central network security and Information Technology Commission (hereinafter referred to as the "network information office") issued the notice on doing a good job in personal information protection and using big data to support joint prevention and control. The purpose of the notice is to "protect the personal information in the joint prevention and control of New Coronavirus infection," and "use big data including personal information to support joint prevention and control work".The notice of the Internet Information Office has played a deterrent role to individuals and institutions trying to disclose personal information, but it is difficult to eliminate information leakage. If blockchain technology is used in the process of information collection, the worry of the office will not be enough.Chaotic personal information collectionSince the "closure of Wuhan City", the author has been required to fill in various information collection forms, including community property management, community neighborhood committees, work units, children's schools, etc. the author has identified their entities, as well as unconfirmed entities such as "municipal government", "Public Security Bureau" and "Health Commission" spread in the community.There are various ways to fill in, including H5 format, wechat applet and word document. For example, hundreds of related small programs are running when wechat searches for keywords such as "epidemic situation", "anti epidemic", "epidemic prevention", "new crown" and "virus registration".There are many kinds of information collection tools, including individuals, outsourcing companies and large Internet companies, which means that the servers storing this information are different and the security is questionable.From the collection of personal information, it involves a lot of privacy issues, including the ID number, telephone number, family detailed residence and family member's detailed list.With these contents, you can do many illegal things: including being taken by other people's ID card and telephone number for various member registration and handling various membership cards; The ID number and mobile phone number can be copied to the same mobile phone number, resulting in loss of property in the bank card. Have very accurate identity information, sell it to advertisers and be harassed by advertising; Reselling information to fraud companies can make it easier for fraud companies to make up stories that people believe.In fact, personal information leakage has occurred before the epidemic is over. Guangzhou Nanhai District has just investigated and dealt with a case. A passenger in Nanhai took a cruise ship, and there was an epidemic on the cruise ship. The passenger's Avatar, identity and other information were spread.This is why the online information office should send a document to protect personal information.According to the notice of the Internet Information Office, the personal information collected for epidemic prevention and control and disease prevention and control shall not be used for other purposes. No unit or individual may, without the consent of the collector, disclose personal information such as name, age, ID number, telephone number, home address, etc., except for the need for joint prevention and control and desensitization. The notice also points out that institutions that collect or master personal information should be responsible for the security protection of personal information and take strict management and technical protection measures to prevent theft and disclosure.From the perspective of the main body of information collection and technical service companies, it is not easy to meet the requirements of network information office. Luo Xiao, CEO of Yulian technology, said to the pulse of mutual chain: "there are indeed many links in the form of H5 on Web pages to obtain citizen information. Moreover, due to the limited technical ability of some technology companies, it is extremely easy to cause the disclosure of citizen privacy information regardless of experience."Blockchain technology is being used to collect personal information for epidemic prevention because it can protect users' privacy. For example, the "access" developed by Yulian technology is deployed on the Yulian cloud based on blockchain technology to encrypt and protect the collected citizen information, which can ensure the security of data. Luo Xiao said: "even Yulian technology can't see the user information, and after the epidemic, it will publicly destroy the deployment of this product."Blockchain and use of private dataIt is worth noting that in the notice of the Internet Information Office, it not only requires the protection of personal information, but also puts forward two requirements.First, the health department has the right to call. The notice stipulates that except for the institutions authorized by the health department of the State Council in accordance with the network security law of the people's Republic of China, the law of the people's Republic of China on the prevention and control of infectious diseases and the regulations on emergency response to public health emergencies, no other units or individuals shall collect and use personal information without the consent of the recipient on the grounds of epidemic prevention and control and disease prevention.Second, collect information differently. The notice stipulates that the collection of personal information necessary for joint prevention and control shall refer to the national standard personal information security code, adhere to the principle of minimum scope, and the collection object shall be limited to key groups such as diagnosed persons, suspected persons and close contacts. Generally, it does not target all groups in a specific area to prevent de facto discrimination against people in a specific area.However, the current personal information collection methods are difficult to meet the requirements of notification. For example, if the health department invokes data, its operators can certainly obtain this data; At present, we would rather collect all the information than miss one person.However, blockchain has given solutions on both points.For example, on July 30 last year, Lai Xin, chief engineer of Xunlei chain, released the new technology of Xunlei chain - traceable privacy protection technology at the 4th China Network and information security conference. This technology is to solve the pain point that it is difficult to achieve both data privacy protection and information traceability on the chain. It is reported that this technology encrypts and hides data through encryption algorithms such as ring signature and zero knowledge proof, so as to protect user privacy, meet the needs of organizations or institutions with information control authority through cryptography technology, and minimize risks. In this way, the problem that the health department invokes information but others are invisible is met.Previously, Xunlei chain's "chain data regulatory privacy scheme" has been applied in medical scenarios. This scheme can also be applied to the collection of epidemic prevention personal information. For example, relevant collected objects can upload data encryption to the chain through supervised privacy encryption technology to protect the privacy of the data uploaded to the chain. Regulators with data access authority, such as provincial and municipal CDCs, can view the ciphertext data on the chain through the regulatory key, so as to ensure the timely and effective data and achieve security and controllability.
