Amazing Inventions

Biometric padlock: 
Everyone has lost their keys at some point but it’s a lot harder to lose your fingers. That’s why a new biometric padlock is a godsend for people who are prone to mislaying their stuff. Its sensors let you use your fingerprint as the key and store those of your friends so that they can also use it.  It opens when you slide your fingers over it, by scanning your digits and matching them to its records. The lock can store up to ten fingerprints, so you can give other people access without the hassle of lending or copying keys.It is a vast improvement on the security provided by a standard padlock. You don’t have to worry about the keys getting stolen or about someone else guessing or finding the written reminder for a dial code. And you can add and revoke other users via their fingerprints whenever you like.This padlock  can be opened via an app on an iOS or Android device, without the need for keys or a dial code. The Liquid Wallet by Melbourne, Australia-based company Liquid incorporates house keys into its design so that users can store all of their essential items in one place.You may store up to 200 different fingerprints. The padlock app is compatible with Android, OS and Windows.The history function of the mobile app allows you to keep a track of padlock use by your family and friends.
Zero  Helicopter :
  ZERO Personal Helicopter concept is a new innovative way to avoid traffic jams and serve as as a personal urban transport. It’s a quite interesting solution considering size of urban congestion, this zero-shaped ultra-light and pretty compact flying vehicle is designed by by Hector del Amo and looks more compact compared to the smaller helicopter, the mosquito one.Moving from one place to another without having to deal with traffic jam is always been a dream of us since long. This single person vehicle is no ordinary chopper, well it’s not a private jet, but it does the job in a very cool way. In theory this ZERO helicopter would not only be energy-efficient, it would also be easy to handle, cost efficient and most importantly it takes only a smaller area to land than a regular helicopter. There are still some flaws in this concept, specially there are no doors in ZERO helicopter which exposes the passenger to more danger. Although rather than producing a smarter car it will be much easier to introduce a flying transportation system that will also be a good way to reduce road traffic.
carpet alarm clock: 
It takes a stronger person than me to actually get out of bed when the alarm goes off—after all, that snooze button is so conveniently located. But if the alarm didn’t stop until I was out of bed, there’s a chance I could actually eat breakfast one of these days.That’s the idea behind Ruggie, a pressure-sensitive alarm clock that lives on your floor, and only turns off when you stand on it. It looks pretty much like a regular lamp, apart from the small display in the corner. Power comes from three AA batteries that apparently last a full year, while you hook it up to a computer to set the alarm, and customize features.It’s currently crowdfunding on Kickstarter, where $80 snags you an early-bird version. As ever, buyer beware on crowdfunding websites, although there’s no danger of Ruggie being underfunded: they’re at $100,000 in a week, with a good 52 days still to go.
preset faucet: 
The water saving sensor systems are factory preset with a 30 second time-out feature (field adjustable in 15 second intervals) to prevent sink flooding incidents whether accidental or as acts of negligence and / or vandalism. Water damage, especially in multi level buildings can be extremely expensive to rectify with the ever escalating costs for materials, labor, mold mitigation, increased insurance premiums, and the possible loss of revenue in hotel or rental properties. Preventing wet floors in public buildings can also reduce insurance claims related to slips and falls. One of the greater benefits of sensor faucets is that they turn off automatically. Beyond that obvious benefit of water conservation, these automatic faucets with preset time-outs are designed to save building owners from over flow water damage. This is a huge plus in environments where people tend to leave the water running unnecessarily such as office buildings, public restrooms, institutions, assisted living environments and other places where an unattended faucet can waste water and cause damage.The average return on investment for sensor devices is calculated to be near 30 percent. The higher the water costs, the greater the return. The lower the water costs, the longer it takes to recoup costs. The payback period is generally 3-6 months.
The self-sterilizing door handle:
The self-sterilizing door handle is a Red Dot Design Concept winning entry created by Choi Bomi. As opposed to door knobs, its design features a handle that rests horizontally and meant to push down to unlock the door. Simple enough. How the handle self-sterilizes is through the use of UV light that runs through the handle when it’s not in use. In the closed position, the handle clicks into place horizontally and pushes the switch to keep the UV lamp on which effectively makes any bacteria residing on the handle unable to reproduce, spread, or cause disease.The handle is just a concept for now, and there’s no way to tell if it’ll ever see wide production, but it’s definitely a good idea that might make public restrooms a little more sanitary. It’s no excuse for not washing your hands, though.
Handheld tattoo printer:
Handheld tattoo printer is a breakthrough in tattoo technology, using a skin-safe proprietary E ink encapsulated pigment system that lasts a lifetime but can be configured to display any design (or none!) to suit your mood. Sensors in the printer read the texture of the skin, adjusting to muscles and bones as it prints up the tattoo. The canvas can go anywhere on your body and be configured to the size and shape of the body party you'd like to ink.  After testing on artificial skin, the people behind Appropriate Audiences tattooed a perfect circle on their first human subject in 2013.While the team works out the kinks in the software, they're limiting Tatoué to arm tattoos and simple designs. The French-based art and design group plans to consult with tattoo artists to learn new techniques to make the tattoo print job a more efficient process. After that, quick and easy computer-driven tattooing could be coming to forearms and necks near you.You want can be designed on the computer, and replicated onto the skin. We are still working to develop the software in order to produce something that is more user-friendly, particularly for tattoo artists.The needle replaces the part of the printer that would usually extrude melted plastic to make objects, and has been adapted using bespoke 3D-printed parts. A sensor reads the surface of the skin of the user, meaning the needle can respond to changes in skin texture and the dimensions of the limb.
