                                                            THE FAMILY FLIER

A homebuilt airplane designed with maximum efficiency in mind.

                       John McGinnis thinks ordinary families would rather skip the airport and fly themselves. So he is trying to reinvent the personal airplane with the help of his father, son, and a rotating crew of about two dozen volunteers. Unlike small aircraft today—which can cost more than a house—McGinnis says Synergy could be cheaper, quieter, and, at more than 40 mpg, three times as fuel-efficient.

McGinnis, a 47-year-old composite manufacturer, flew his first airplane in second grade. Perplexed by the inefficiencies of personal aircraft, he taught himself aeronautical engineering and fluid dynamics over two decades. One day, while perusing scientific studies at a desk in his daughters’ bedroom, he read a NASA researcher’s paper challenging a classic aerodynamic drag equation. McGinnis could see the possibilities. “I came out of the girls’ bedroom ranting like a madman to my wife,” he says. “ ‘Honey, you’re never going to believe this. I think I just solved a problem I’ve been working on since I was a little kid.’”

Synergy’s wings bend upward and into a box shape for minimum drag and maximum efficiency. The top half of each wing swoops behind the body to function as a tail while providing greater in-flight stability. The double-box tail design also makes gliding easier by counteracting tornado-like vortices at the wings’ tips. And instead of a front-mounted propeller, an impeller placed behind the bullet-shaped body quiets noise while adding thrust.

1) A 200hp turbodiesel engine expels heat below the impeller, adding thrust.
2) Large wings allow slower takeoffs and landings.
3) Box tails create airflow patterns that reduce drag and increase flight stability.
4) An autopilot computer can land Synergy at a nearby runway during an emergency; a ballistic parachute can also be deployed.

McGinnis works on Synergy in his father’s garage, where he uses CNC machines and custom molds to fabricate components and 3-D software to rapidly model new ideas. Family members serve among the core build crew, with McGinnis’s son, Kyle, second-in-command. A quarter-scale prototype made from fiberglass, carbon fiber, and Kevlar suggests that both the team’s manufacturing process and unusual wing configuration work. Using about $80,000 in crowdfunded cash, they hope to finish a full-scale, five-person aircraft this year. “I work on it 90 hours a week, with a few hours of sleep,” McGinnis says. “What drives me to do it is that no one else will.”

5. Eye Tribe

Eye tracking has been actively discussed by technology enthusiasts throughout these years, but it’s really challenging to implement. But Eye Tribe actually did this. They successfully created the technology to allow you to control your tablet, play flight simulator, and even slice fruits in Fruit Ninja only with your eye movements.

It’s basically taking the common eye-tracking technology and combining it with a front-facing camera plus some serious computer-vision algorithm, and voila, fruit slicing done with the eyes! A live demo was done in LeWeb this year and we may actually be able to see it in in action in mobile devices in 2013.

Currently the company is still seeking partnership to bring this sci-fi tech into the consumer market but you and I know that this product is simply too awesome to fail.

6. SmartThings

The current problem that most devices have is that they function as a standalone being, and it require effort for tech competitors to actually partner with each other and build products that can truly connect with each other. SmartThings is here to make your every device, digital or non-digital, connect together and benefit you.

3. Oculus Rift

Virtual Reality gaming is here in the form of Oculus Rift. This history-defining 3D headset lets you mentally feel that you are actually inside a video game. In the Rift’s virtual world, you could turn your head around with ultra-low latency to view the world in high resolution display.

There are premium products in the market that can do the same, but Rift wants you to enjoy the experience at only $300, and the package even comes as a development kit. This is the beginning of the revolution for next-generation gaming.

The timing is perfect as the world is currently bombarded with the virtual reality topic that could also be attributed to Sword Art Online, the anime series featuring the characters playing games in an entirely virtual world. While we’re getting there, it could take a few more years to reach that level of realism. Oculus Rift is our first step.

4. Leap Motion

Multi-touch desktop is a (miserably) failed product due to the fact that hands could get very tired with prolonged use, but Leap Motion wants to challenge this dark area again with a more advanced idea. It lets you control the desktop with fingers, but without touching the screen.

It’s not your typical motion sensor, as Leap Motion allows you to scroll the web page, zoom in the map and photos, sign documentss and even play a first person shooter game with only hand and finger movements. The smooth reaction is the most crucial key point here. More importantly, you can own this future with just $70, a price of a premium PS3 game title!

If this device could completely work with Oculus Rift to simulate a real-time gaming experience, gaming is going to get a major make-over.

1. Google Glass

Augmented Reality has already gotten into our life in the forms of simulated experiment and education app, but Google is taking it several steps higher with Google Glass. Theoretically, with Google Glass, you are able to view social media feeds, text, Google Maps, as well as navigate with GPS and take photos. You will also get the latest updates while you are on the ground.

It’s truly what we called vision, and it’s absolutely possible given the fact that the Google’s co-founder, Sergey Brin has demo’ed the glass with skydivers and creatives. Currently the device is only available to some developers with the price tag of $1500, but expect other tech companies trying it out and building an affordable consumer version.

2. Form 1

Just as the term suggests, 3D printing is the technology that could forge your digital design into a solid real-life product. It’s nothing new for the advanced mechanical industry, but a personal 3D printer is definitely a revolutionary idea.

Everybody can create their own physical product based on their custom design, and no approval needed from any giant manufacturer! Even the James Bond’s Aston Martin which was crashed in the movie was a 3D printed product!

form 1
(Image Source: Kickstarter)

Form 1 is one such personal 3D printer which can be yours at just $2799. It may sound like a high price but to have the luxury of getting producing your own prototypes, that’s a reaonable price.

Imagine a future where every individual professional has the capability to mass produce their own creative physical products without limitation. This is the future where personal productivity and creativity are maximized.

WORKING OF A MODEM


    

Suganya.S - MEC ( ITE )     2013-07-24 22:00:47


     



                                                                    BOUNCE IMAGING


      After an earthquake devastated Haiti in 2010, search-and-rescue teams descended upon Port-au-Prince to look for survivors. Francisco Aguilar, a graduate student in public policy at the time, was shocked to read stories about crews relying on complex, expensive imaging systems. “Only a few teams had them, and you had to be really well trained to use them,” Aguilar says. He soon launched a start-up in Cambridge, Massachusetts, to develop a simple way to explore hard-to-reach places: a throwable, expendable, baseball-size probe.

The Bounce Imaging Explorer has a shock-absorbing shell embedded with six cameras, plus clusters of near-infrared LEDs to light up dark rooms (for the cameras). To deploy the Explorer, an emergency worker links it to a smartphone or tablet and chucks the ball into danger. It immediately begins taking photos and testing for methane, carbon monoxide, and dangerously high temperatures. A microprocessor inside the ball then stiches the photos together and converts the raw data for transmission over Wi-Fi. Just seconds after the toss, a wrap-around panorama—complete with environmental warnings—appears on the synced device.

Aguilar quickly imagined applications beyond disaster areas, such as burning buildings, hostage crises, and combat zones, so he sought feedback from potential customers. His start-up cranked through dozens of prototypes in the first 18 months, tweaking the design as requests poured in. When several police officers said they wanted to be able to hear inside a room, for example, Aguilar added a digital microphone.

Police, firefighters, soldiers, and nuclear-plant inspectors have offered to test the device, which Aguilar is determined to keep between $500 and $1,000. “We want to get it as cheap as possible so it can be as broadly deployed as possible,” he says.

                                                    HYPER....


     Semitruck drivers idle their engines to heat or cool their vehicles’ cabs—a practice that burns a billion gallons of fuel each year. Small engines on the back of a cab, called auxiliary power units (APUs), get the job done with less fuel, but they’re loud and smelly. A team of five Ontario-based engineers and mechanics has devised what may be a better solution: an APU called HYPER that runs on waste heat.

The group originally formed to build a 100mpg car for the 2008 X Prize competition. During one brainstorming session, someone wondered aloud: Why not use energy from a vehicle’s exhaust to run an HVAC system? “We did a lot of modeling and realized that the energy numbers made sense,” says team member Jack MacDonnell. He and two others decided to work full-time to develop a new kind of APU.

Like a household refrigerator yet a third the size, HYPER chills air by depressurizing a liquid refrigerant under high pressure into a gas—a process that absorbs energy. The gas then condenses to start the cycle anew. But instead of using electricity to drive the process, HYPER does it with a semitruck’s 660°F exhaust heat. MacDonnell says the APU stores between six and 10 hours of heating or cooling capacity after an hour of driving. Based on early tests, he thinks the device could cut a trucker’s yearly fuel consumption by 9 percent and carbon emissions by about 20 tons.

The team is testing HYPER on a retrofitted semi in hopes of selling road-ready devices in 2014. With 2.5 million trucks on U.S. roads, HYPER could make a significant impact—but the team also hopes to retrofit buses, RVs, passenger vehicles, and more. “We would drastically cut emissions, fuel consumption, and be less dependent on foreign oil,” MacDonnell says.

HYPER Diagram:  Graham Murdoch

HOW IT WORKS

1) 660°F semitruck exhaust heats a refrigerant mixture [red] flowing through an exchanger. The refrigerant’s solvent boils from its solute, pressurizing the HYPER system.
2)
A second exchanger uses a fan to help cool and condense the refrigerant into a high-pressure liquid.
3)
The refrigerant [yellow] passes through a nozzle, flashing it into a gas [blue]. This draws heat from an adjacent fluid loop, cooling it to about 23°F [green].
4)
A reservoir stores the chilled fluid.
5)
Air blown across an evaporator (fed by chilled reservoir fluid) cools the truck cab.
6)
A final exchanger condenses the refrigerant into a liquid to restart the cycle.

                                              PALM VEIN AUTHENTICATION DEVICE

An individual first rests his wrist, and on some devices, the middle of his fingers, on the sensor's supports such that the palm is held centimeters above the device's scanner, which flashes a near-infrared ray on the palm. Unlike the skin, through which near-infrared light passes, deoxygenated hemoglobin in the blood flowing through the veins absorbs near-infrared rays, illuminating the hemoglobin, causing it to be visible to the scanner. Arteries and capillaries, whose blood contains oxygenated hemoglobin, which does not absorb near-infrared light, are invisible to the sensor. The still image captured by the camera, which photographs in the near-infrared range, appears as a black network, reflecting the palm's vein pattern against the lighter background of the palm.

An individual's palm vein image is converted by algorithms into data points, which is then compressed, encrypted, and stored by the software and registered along with the other details in his profile as a reference for future comparison. Then, each time a person logs in attempting to gain access by a palm scan to a particular bank account or secured entryway, etc., the newly captured image is likewise processed and compared to the registered one or to the bank of stored files for verification, all in a period of seconds. Numbers and positions of veins and their crossing points are all compared and, depending on verification, the person is either granted or denied 

The completely contactless feature of this Device makes it suitable for use where high levels of hygiene are required It also eliminates any hesitation people might have about coming into contact with something that other people have already touched.

In addition to being contactless and thereby hygienic and user-friendly in that the user does not need to physically touch a surface and is free of such hygiene concerns, palm vein authentication is highly secure in that the veins are internal to the body and carry a wealth of information, thereby being extremely difficult to forge.


There may be a chance that the palm we had registered may get damaged then we cannot use this technology, so during the time of registration we take the veins of both the hands so that if one gets damaged we can access through the second hand. When hand get damaged up to large extent we can get veins because deeper into the hand veins are obtained. When we apply this method we can maintain complete privacy .

1.   Homemade Greeting Cards

o    Homemade greeting cards are an excellent way to express heartfelt sentiments to friends and family. Although homemade greeting cards are usually thought of as a children's craft, they make a fun activity for grown-ups too. Fold a piece of heavy construction paper in half and cut the unfolded edges with pinking shears for a polished look. Cut, layer and glue various colored, shaped and sized pieces of construction paper onto the front and inside of your greeting card for an eye-catching design, and use letter stencils to give text a sophisticated, playful or professional feel. Add small embellishments, such as a tiny ribbon bow or a piece of felt, to the front of the card for an extra special touch.

Construction Paper Flowers

o    Construction paper flowers are fun and easy for people of all ages to make and can add a whimsical touch to any room. Cut a flower shape out of two sheets of different colored construction paper. Glue the flower pieces together, positioning one on top of the other, overlapping slightly, to give your flower a multi-colored, multi-dimensional look. Cut a small foam ball in half and glue one of the halves, smooth-side down, onto the center of the flower. Gently push a piece of thin, pliable wire up through the back of the flower and into the Styrofoam center of your flower. Glue a few construction paper leaves onto the wire for a fresh-cut look.

                         TO DETECET A LOST MOBILE USING SNIFFER

The sniffer is a small base station, it includes transceiver section. It should operate at a frequency that is much different from the frequency of the current cell in which the operation of detection is being carried out. Some of the main important things are the frequency that has to be generated by the transceiver section is around 900MHz range which is a VHF range and it is necessarily to design the oscillator circuit for that frequency range .Another important is the cooling that has to be provided to the circuit while designing the circuit that is to be operated at 900MHz range of frequency. Hence proper design of base station is an important thing in the design of the sniffer. Mobile phones as well as the base station has low power transmitter is also transmitting at low power. The transmitter of the sniffer has to be a low power transmitter. This helps in the process of reducing the interference of the device with the devices that are in the other cells.

Working Of The Sniffer Device

The sniffer is basically a transceiver that works in the frequency which is in the special unused range that is operated by the service provided or it can designed to operate at a frequency that is of much different frequency than the one that is being used by the nearby cells as there may be possibility of interference by the device with the devices in the nearby cells. The working for the device is as follows. The fig 2 &3 shows the working of the sniffer ; as given in the fig2 it gives the normal operation of the mobile with the base station and there is a BTS that acts as a middle man in the process of communication between the mobile and the MTSO which is popularly known as MSC or Mobile Switching Centre .There is always a two way communication between devices and before the establishment of the communication the authentication of the SIM card that has the IMSI or the International Mobile Subscriber Identifier

.This IMSI number helps in the authorization of the user. The second authentication is the authentication of the handset, which is done in EIR or the Equipment Identifier Register. This register is located at the MSC and it contains the IMEI number of the lost handset and if the signal is obtained from the normal one then the two way communication is established. The IMEI of the lost mobile phone number once has been reported to the service provider, who keeps in track of the record of lost mobile phones. The MTSO or the MSC which keeps in track of all the mobile phones with IMEI number and the IMSI number has the information of the lost mobile phones location which means the location of the cell where the lost device is because of the two way communication with the device the BTS of the lost device is known to MSC. From this information regarding the cell in which the device is located the sniffer device is introduced.

 

After the information regarding the IMEI number of the lost device is provided by the MTSO or MSC .This is then fed into the sniffers main memory the sniffer's located in particular cell gets into action of detecting the lost device. The sniffer uses a frequency that is different from the one that is being used by the base station and the located nearby cells .The base station disconnects the connection with the lost mobile phone, as there is a request regarding this action from the EIR part of the MSC. This causes the lost device to search the BTS to get locked with since each base station does not have authorization capability the lost device send appropriate connection request signal. Now when the sniffer device is being deployed and this device has in built authorization capability the lost device finds the sniffer to get itself locked to the frequency of the SNIFFER.
