Xray vision night vision infrared5/7/2023 ![]() 25 difference on the lens focus.Īnyone can go to a public beach and see more nudity than one could see in a public market place. Going the Infrared route instead of the shorter ultraviolet route there is a difference in the focal length causing bad focus problems unless you have the handy gauge on the lens itself. The biggest reason some kind of X-ray capability would be useful other than porn is detecting malignant tumors more readily. It only lets through these long-wavelength rays, which have low refractive rays, and not all the ultraviolet and visible rays.” The KAYA PF exploits this characteristic of infrared light. At the other end of the spectrum, beyond the red, visible light, infrared rays are barely refracted at all because of their long wavelength. The blue end of the visible spectrum has the shortest wavelength, so is refracted the most. When we shine sunlight through a prism, it is refracted at an angle according to its wavelength. This also means that infrared rays are not refracted much at all when passing from one medium to another. Unlike ultraviolet and visible rays, infrared rays tend to penetrate any medium rather easily because of their large wavelengths. We divide them into “Near Infrared Rays” (690nm-4,000nm) and “Extreme Infrared Rays” (over 4,000nm). (1nm=10-9m) Infrared rays have much larger wavelengths than this. “The visible part of the spectrum falls between the wavelengths of 430nm~690nm.

It sounds like science-fiction but it isn’t this fantastic new product has been developed using the most highly advanced optical technologies available,” explains Kaya.ĭid Kaya really make an x-ray vision lens? How is it possible? Here’s Kaya’s explanation does it sound like sound science to you?: The PF makes it possible for you to see images that are normally invisible to the human eye. “The PF is a special optical device that helps to visually penetrate an object’s surface in order to view whatever lies below. This is genuine xray vision, as easy as screwing a filter on your camera lens.Īccording to Kaya, their x-ray vision lens allows you to not only see through clothes, but a host of other materials. X-ray vision allowing you to see through clothes and other things, once a fantasy of children and men everywhere (although for different reasons), has become a reality with the Infrared See-Through Filter PF xray vision lens by Kaya. I just wish I could figure out how we got to thinking that infrared was one of them.(Looking for our article about the new T-ray x-ray vision security system? Click here) So there's plenty of ways for futuristic soliders and talking cars to see through walls. The system can see through concrete, reinforced concrete, wood, brick, and pretty much anything except a continuous sheet of metal. The system relies on Ultra Wide Bandwidth signals, a method that relies on timing and and a large selection of radio wavelengths, rather than sheer power (Traditional uses of radiowaves use a narrower part of the spectrum but are higher power). Or how about a little mini-radar type system? The Xaver 800 can see into a room, map it onto a screen, and maintain real-time, three dimensional updates on the locations of people within the room. The LEXID collects X-rays in the same way. Where the human eye uses a lens to refract light onto the optic nerve, a lobster uses a series of tiny biological "mirrors" to project disparate light beams onto a single focal point. It's actually pretty neat, the designers modelled it on the vision system used by lobsters and other crustaceans. The LEXID looks like a flashlight, but it uses X-ray emissions to see through up to three inches of steel. The Lobster-Eye X-Ray Device (LEXID) uses X-rays (like Superman!) to see through walls. Luckily, there are many excellent real ways for KITT to see through walls. But the insulated walls of buildings are designed to block heat from escaping, essentially forming a.well, a wall between the camera and person in the building. These cameras, like night vision goggles, pick up lower wavelength electromagnetic signals that we sense as heat. So, for the record, infrared cameras cannot see through walls. Not that I particularly blame Knight Rider , because it's such a common meme. ![]() Will someone please explain how this whole infrared-can-see-through-walls thing got started? It comes up everywhere: James Bond used it, One of the iterations of CSI used it, then KITT used it on last night's episode of the New and Improved Knight Rider (now with more humor!).

Snpachat filter designer5/6/2023 ![]() ![]() This new feature gives businesses a chance to get their names in front of users for as little as $5. On-demand geofilters, which are also free to Snapchat users, launched in late February. On-Demand Geofilters: Before on-demand geofilters, the opportunity for businesses to increase their brand awareness through a sponsored filter could reach as much as $700,000 each day.Community geofilters can’t include business logos. Community Geofilters: These free geofilters, designed by artists and designers, catch a user’s attention by allowing them to them note on their photo where they were when they took the picture.Snapchat recently expanded its geofilters, and now offers two types: Snapchat tries to keep geofilters for each area to a minimum, and must approve each geofilter before making it available to users. ![]() Geofilters are often used by parks, cities, universities, and now, businesses. The app automatically overlays a digital sticker, or the geofilter, of their location over their photo. Users who have enabled location services in their smartphones can place an available geofilter on their photo with a quick swipe of their finger. Geofilters have long been a favorite feature in Snapchat. To enhance their ad program, Snapchat has started offering on-demand geofilters – an excellent new tool for restaurant owners looking to increase their business and reach. Its quick rise to popularity may be attributed to teens and their selfies, but in the past few years, companies have been increasingly capitalizing on the app’s appeal and have seen positive returns from marketing with Snapchat’s other advertising opportunities. With some patience and hard work, you’ll have your own Snapchat geofilter in no time.Snapchat has been a growing as a social media marketing tool for years and now counts more than 100 million daily active users since launching in 2011. Is any text too dark or too light? Try using a different font or color, or scaling your design down a notch. Try testing your geofilter against different photo backgrounds. Try resizing your geofence a bit larger or writing a better description. While Snapchat won’t detail why submissions get rejected, a few simple tweaks can often go a long way. If you do get your design rejected, don’t despair. That way the filters will appear just as you are chugging down the first beer of the night or crying at the altar. You can also create two separate geofilters to appear at different times to save money. By skipping the expensive areas like stadiums, convention centers, and any dead space that’s unrelated to your geofilter, you will do your wallet a favor. The trick to avoiding high costs is to create two geofitlers and apply them where you want to see the filter. The location of the geofilter applied can change depending on where you drag and select during the creating process. The price tag of a geofilter depends on the size of the area, the amount of time it’s live, and what the boundaries contain. ![]() How to create a Snapchat geofilter (and get it accepted): 1) Dream up the right-sized geofilters rejected again. But if you want to celebrate your city or neighborhood or a public event, definitely take the time to get your design accepted as a Snapchat community geofilter. If budget is not a concern but time and convenience is, an on-demand geofilter is the way to go. With on-demand, you can design and submit a geofilter and have it accepted within one business day-for a fee. This option is perfect for those who still want a geofilter that may not apply to the broader user base required by Snapchat’s community geofilter guidelines. If you’re mere weeks away from a wedding or other high-profile event, you may want to opt for Snapchat’s on-demand geofilters option. How to get Snapchat’s new selfie lenses.Essential Snapchat hacks, tips, and tricks.While that’s no easy success rate, with careful planning and some preparation, you can get Snapchat’s illustrious stamp of approval on your geofilter. One redditor recounted submitting 30 of his own designs, only to have 24 of them accepted by Snapchat. Snapchat reviews every entry to its Community Geofilters site to make sure they follow its guidelines. Schools and universities have jumped on the bandwagon too. People have designed their own filter overlays to commemorate weddings, NBA games, even birthday parties.īut getting the geofilter of your dreams into Snapchat is harder than it looks. There are Snapchat geofilters to honor locations that range from famous landmarks like the Eiffel Tower to the Columbia Heights neighborhood in Washington, D.C. Find my Snapchat geofilters around #NYFW. ![]() When something is fun, we experience it as inherently rewarding for its own sake. This suggests an innate connection between playing and learning. We role-play an activity in a simplified form, as practice for the real thing later. It's mainly the children and young who do it, often with help and supervision of adults. Many of our cousins in the animal kingdom engage in play as well, like our dogs and cats. It is a universal pastime enjoyed by humans everywhere. For one, play is not a mindless activity. I think this is incredibly short sighted. Games are often seen as mere entertainment and distraction. To understand why, let's talk about pedagogy and games. You'd think this would make things so much easier, but in many ways it doesn't. Though it'll take a while before that revolution is equally televised everywhere. Lambdas and pure data are now topics you need to have mastered before you can call yourself properly senior. What's more, we have entered an age where programming is slowly but surely getting over its teenage infatuations. You can even go look at the development process of some of the most successful projects out there, all in the open. You can find instant StackOverflow answers for ridiculously specific questions. It's fine.īy comparison, today you can click just one link and have a fully functional live coding environment at your fingertips. That it's perfectly normal to have to manage an arcane bureaucracy of structs just to do what every other normal application does every day. Meaning, for years I just assumed that all "serious" UI-related code was a giant dumpster fire.

This additional feature uses radar technology to track the movement of prowlers within your property, and in addition to the camera’s live feed, 3D Motion Detection enables a Bird’s Eye View of your lawn. It also has a 110-decibel siren, plenty loud even for an outdoor camera.Īn even more advanced version of the Spotlight Cam was released recently at the 2022 Amazon hardware event, which also features 3D Motion Detection. This $200 camera comes equipped with bright spotlights that you can program to turn on when it detects motion. Ring has an expansive product catalog, but let’s take a look at one example: For most climates, the Ring Spotlight Cam is one of the best weatherproof cameras for scaring off prowlers as it can withstand temperatures five degrees below zero. Ring cloud video storage costs $3 per month for one camera or $10 per month for an unlimited number of cameras installed in one address. Smart integrations let us control our home alarm system with voice commands and send our security video to various in-home displays of our choice. ![]() Other Ring camera models include motion detection, two-way voice, and Amazon Alexa and Echo integration like the doorbell cameras. And in terms of cost, the Spotlight Cam Pro is competitive, with prices ranging from $229 to $249. This high-tech camera uses radar to improve its motion detection, and it can even provide you with a simulated Bird’s Eye View of your property to give you a better vantage point. One example is the Spotlight Cam Pro, released in September 2022. We valued having the option to choose between so many cameras, including wireless and hardwired models, all at competitive prices. How We Review Why Ring Has the Best Security Camera Selection OverallĪmazon-owned Ring initially gained popularity for its doorbell cameras, but it also sells indoor cameras, outdoor cameras, an over-the-peephole camera, and other home security equipment. Their latest creation is the 4K Wi-Fi Security Camera, which uses AI to improve alerts and comes equipped with Wi-Fi 6 technology to improve video transmission. It’s also worth noting that Lorex is one of the largest security camera manufacturers today, with new products being released on an almost-monthly basis. However, it’s a really solid and budget-friendly option, which is true for most Lorex cameras. It’s not a perfect camera it doesn’t work in below zero temperatures, for instance. It also comes with the ability to record both video and audio. It has a 118-degree wide-angle lens and a whopping 115-foot night vision range. We think this camera really represents Lorex well. It’s an affordable but dependable camera, retailing for as low as $149. One bestselling home-use Lorex camera is the 1080p HD Outdoor Wireless Security Camera. Without further ado, we give to you the best security cameras you can buy today. We’re basing our recommendations on our first-hand experience with these brands, but also on thousands of hours of research. ![]() Today, we’re going to look at those elite brands that make up the best security cameras in the market. ![]() Needless to say, the rapid evolution of security camera technology spawned hundreds of different camera options for dozens of competitive security camera brands. ![]() And Ring’s newest cameras even have radar technology that give you a birds-eye-view of your home. There are cameras that “talk” to ward off intruders. There are security cameras nowadays that can tell people apart from other moving objects, detect packages delivered, and even recognize people. More importantly, their features have improved tremendously. From those clunky artificial eyes we used to see in large commercial buildings, over the past decade they’ve become more commonplace in residential areas. Security cameras sure have come a long way. Metin2 private server5/6/2023 These terms are meant to give new players who don't know a server yet an overview of what kind of Private Server it is approximately. For this reason, a classification has evolved over the years between 3 different types of servers: Naturally, everyone has a different idea of what the perfect Metin2 server is. To sum it up, the P-Server scene has been created by many individuals and security holes of the official Metin2 server, to what we know today. Probably the best-known cheat program was the Metin2 bot “M2BoB”. Even if this part of the Metin2 Community is viewed negatively, this is nevertheless a huge part of what keeps Metin2 alive, even after so long. EPvP offers a forum for exchanging news, hacks, information and everything else around Metin2 private servers.Įven today, EPvP is still one of the most popular forums regarding Pserver and contact points for server admins who want to promote their server.Īs in any online game, there are so-called hacks or bot programs for Metin2. The hobby programmers have developed into experienced Server Admins and manage today’s servers with sometimes thousands of players.Ī significant role in the Emergence of today’s Metin2 Pserver scene played the website “ElitePvPers”, short “EPvP”. In the beginning, the curiosity and the fun at developing new worlds were what the programmers drove, but the more time passed, the more today’s “P-Server scene” rose. Probably the most well-known program over which in the early days the Pserver ran was the VPN client “Hamachi”. ![]() The first Metin2 private servers were created after the release of the official Metin2 server files, which hobby programmers took advantage of to create private servers for the first time. In summary: Should you play a Metin2 private server? If you are tired of hours of levelling, boring questing and spending a lot of money, then you should definitely try a private server.Īnd if you need help figuring out where to start your search, our toplist is a perfect place to start. Game adjustments, new systems or events can be added to the game at any time, thus keeping the complete server climate always at the highest level. ![]() Another advantage that the admins of P-servers have is to have the freedom in any situation to do what is best for the server. Since the private server admins are mostly Metin2 players themselves, P-servers are much more tailored to the player and optimized because the admins are, unlike the company that operates the official Metin2 server, Often, item shop items are also available in the game by farming. While it is on the official Metin2 server only possible to be the best by investing a lot of money, you can belong to the best on private servers for free if you invest enough time.Īlso, P-servers offer an item shop where you can get coins for real money to buy game items, but this is usually much cheaper than the official Metin2 server. A significant factor why p-servers have gained so much popularity is the factor that the official Metin2 is moving faster and faster and more into the "Pay2Win" track.

Most common blood type5/6/2023 ![]() If a person is Rh negative, they may develop antibodies on exposure to Rh positive blood (such as during transfusions or pregnancy). If the RhD antigen is present, a person is Rh positive and if RhD is not present, the person is Rh negative. The Rh systemĪ person’s Rh group can be positive (+) or negative (-).This depends on the existence of antigen RhD on the red blood cells. Thus AB blood type people can be termed universal patients.īut O Rh negative donors can be called universal donors, as red blood cells from such donors can be used for transfusions for all patients. If a person has blood type AB, they don’t have such antibodies, and they can accept transfusions from all other blood types. If you have blood type O, you have antibodies that will fight the A and B antigens. For example: If you have blood type A, it’s imperative that you don’t receive a B type transfusion, as you have antibodies that will destroy B antigens. If a person has A, B or O blood type, their plasma contains antibodies that destroy the antigens that the person doesn’t have. AB - red blood cells have the A and B antigens.B - red blood cells have only the B antigen.A - red blood cells have only the A antigen.This is determined by two antigens on the red blood cells: ![]() The most important blood group system is ABO, in which your blood is classified as A, B, O or AB. The donor’s blood type is identified at the Blood Centre, and the patient’s blood type is determined before transfusion. As a result, blood type match is of critical importance. An antigen is a structure on the cell surface that causes a human immune response reacts to if the structure is foreign to the person’s body. Human blood type is determined by antigens on the red blood cells. But now experts know there can even be risks with this type of blood.If a doctor talks about your blood type, usually he or she is referring to two things: your type in the ABO system and Rhesus (Rh) factor. People with O negative blood were once called “universal” red cell donors because it was thought they could donate blood to anyone with any blood type. That's because type O negative blood cells don't have antibodies to A, B or Rh antigens. Type O negative red blood cells are considered the safest to give to anyone in a life-threatening emergency or when there’s a limited supply of the exact matching blood type. But the donor doesn’t always need to have the exact same type of blood as the person receiving it. It’s best when a donor and recipient are an exact match and their blood goes through a process called crossmatching. People with blood group A can safely get group A blood, and people with blood group B can receive group B blood. In order for a blood transfusion to be safe and effective, it’s important for the donor and the recipient to have blood types that go together. That’s because the person receiving the transfusion has antibodies that will actually fight the cells of the donor blood, causing a toxic reaction. Now experts know that if you mix blood from two people with different blood types, the blood can clump, which may be fatal. Before that, doctors thought all blood was the same, so many people were dying from blood transfusions. You either have this antigen (meaning your blood type is “Rh+” or “positive”), or you don’t (meaning your blood type is “Rh-” or “negative”).īlood groups were discovered in 1901 by an Austrian scientist named Karl Landsteiner. The third kind of antigen is called the Rh factor. Group O doesn’t have A or B antigens but has both A and B antibodies. Group AB has A and B antigens but neither A nor B antibodies. Group B has the B antigen and the A antibody. Group A has the A antigen and B antibody. Doctors call this the ABO Blood Group System. The four major blood groups are based on whether or not you have two specific antigens - A and B. O negative: Someone with this rare blood type (6.6%) can give blood to anyone with any blood type.
