10 Awesome Inventions of 2011


Inventions make our world move. We all need them, we all use them, they are the little engine that helps the human race to advance. The human brain, designed to ask questions, to research and to observe, pushes us further and further on the road of evolution. Every year, enthusiastic inventors expose their creations at the exhibitions which are specially created for them. These self-named innovators are, most of them, eccentric persons that expose funny, weird things with no application. However, sometimes, amazing things come out of their hands. These are the  10 best inventions of 2011.

1. The straddling bus

straddling 1
This is the bus of the future, created to ease traffic, in a world which becomes more and more crowded. This bus is as high and as wide as to permit cars to drive under it.  The straddling bus is not only functional but also attractive and futuristic. It is  economica as welll because it uses sun panels placed on the roof.  These buses are designed to transport up to 1200 persons and the cost of building one of them, together with the required equipment should be 10 times smaller than that of creating a subway line on the same distance.

2. Dynamically Glare-blocking LCD Sunglasses

sunglasses
These glasses are meant to stop sunlight from disturbing us while driving. Apparently, Chris Mullin was annoyed by the glare which gave him headaches during his daily travel to work and back home.  This is when he came with the idea of creating a pair of sunglasses using a unique electronic screen to stop sunlight. This is made out of liquid crystals which are as seen through as any ordinary glass, but its properties may be modified according to the inventor’s desire. In addition, a sensor detects the intense light and instantly sends message to a microcontroller on its location. Further, the liquid crystal acts so as to block the glaze, without modifying visibility.

3.The Medical Mirror

Ming Zher Poh, an electrical- and medical-engineering graduate student at the Massachusetts Institute of Technology is the mastermind that designed the software which allows medics to check for vital signs or help people with a cardiovascular problem to control their health regularly. The patient only needs to stand in front of this special mirror and his heart rate will be displayed on top of his reflection.

4. The Print Brush

print brush
This device was designed by Alex Breton, an engineer in Stockholm, Sweden for a rubber-stamp company. He called his gadget   ‘Print Brush’. The smart printer is able to upload images and text from the computer and then print it on any flat surface and a large range of textures: paper, plastic, wood or fabric. This wasn’t easy to achieve: It took a lot of work, more than 10 years and a large team of experts to transform the prototype into a very precise new tool.

5. The armored sleeve

armour sleeve
This high tech gadget may allow police officers to fight crimes more efficiently. The armour sleeve is equipped with a high voltage stunner, a video camera and a laser pointer which should discourage burglars to become aggressive. The designer of this glove is David Brown, a cameraman, needed 7 years and designed 30 models of the glove before finding the right combination of comfort, ease of use and security.

6. The Formaldehyde testing system

6. Formaldehyde testing system
The device won the silver medal at the Geneva 2011 exhibition of inventions. It was designed by a team from the Institute of Textiles and Clothing, led by prof. Jinlian Hu and it can be used by anybody. The tester is small and user friendly and it is a response to the recent increase in the population’s interest for this substance and its effects on the health. This system allows all of us to check the level of Formaldehyde quickly and precisely, in textile and other objects, such as furniture or walls.

7. Google Prius

google software
Google is testing these days, on Toyota Prius , a software which should allow cars to drive themselves. Apparently, before the actual trip of the intelligent car, a specialist drives along the chosen streets and collect data regarding circulation signs and all the other difficulties. It is only then that the Google Prius starts its drive. However, not by itself; on the driver’s seat, there is a trained person who must take control if needed. Moreover, on the co-pilot seat, there is another expert who permanently verifies the software’s functioning and application. This system, if efficient, should reduce the number o car accidents to a great extent.

8. Terrafugia Transition

transition
This is world’s first flying car. It was designed by students, at MIT and it was developed by a small American company, called Terrafugia. Though the concept of the car was invented in 2006, when it was also rewarded, the first aircraft  is about to be released, this is year. It seems that it can be used both as an aircraft and as a car, due to the ability of folding its wings. The driver, or the pilot, depending on how you put it, will need 20 flying hours to learn how to keep this beauty in the sky ad will be able to buy it at a price starting  from $ 194,000.

9. The Kymera body board

kymers boody board
The Kymera was designed by Jason Woods out of necessity: his sky boat was too heavy and too large and could not be transported and stored easily. This is why he came with the idea of inventing his own watercraft, as light and easy to transport as possible. He finally came up with this design, auctioned by a hybrid electric-propane four-stroke engine and it weights 15 kg only.Put it on the roof of your car and you can head to the water!

10.  Martin Jet Pack

jet pack
This device is another this year’ invention which, if effective, will revolutionise the idea of travelling…light! The design was created by Glenn Martin and it is scheduled for release at the end of this year. Apparently, it still needs some work to be done. However, more than 2500 persons have already reserved the gear and are anxiously waiting for Martin to finish working on his jet pack.

NOTE:
  1. The sensor is a small piece of PC board etched to the pattern showen in the schematic. The traces should be very close to each other, but never touching. A large spiral pattern would also work.
  2. Make sure to use a loud buzzer.

7 Segment LED Counter

This simple counter can be used to count pulses, as the basis for a customer counter (like you see at the doors of some stores), or for anything else that may be counted. The circuit accepts any TTL compatible logic signal, and can be expanded easily.





R1-R7----470 Ohm 1/4 Watt Resistor
U1------- 74HC90
U2------- 74HC47
Disp---- 7 Seg Common Anode


NOTE:

  1. All pulses to be counted are to be TTL compatible. They should not exeed 5V and not fall below ground.
  2. You can add more digits by building a second (or third, or fourth, etc...) circuit and connecting the pin 11-6 junction of the 74LS90 and 74LS47 to pin 14 of the 74LS90 in the other circuit. You can keep expanding this way to as many digits as you want.

Latest Discovery – Neutrinos That Move Faster Than the Speed of Light


From our childhood days, we have studied that nothing in this planet travels faster than light. It has been defined as the ultimate speed in our universe. This has been backed up by many experiments, tests and measurements in many ways possible.
Loading Station at OPERA-CERN

But all these remain as just theories, as a simple neutron transfer experiment conducted by physicists at The European Organization for Nuclear Research (CERN) from their headquarters in Geneva to Gran Sasso Laboratory in Italy (732 kilometres away), proved to be faster than light speed.
The neutrinos had some special characteristics and did not interact with normal matter. As a result, they already predicted that the neutrons would travel fast. Their main aim was to test the frequency of oscillations when the transmission of neutrinos from the source changes its characteristics, as soon as it reaches the destination in Italy. This was when the researchers found something odd with the experiment. The neutrinos reached the destination in a few billionths of a second early. This time proved to be faster than the time of travel of light emitted from Geneva to Gran Sasso.
This is not an isolated anomaly, but has been going on for years. The team has now measured some 14,000 batches of neutrinos coming across that distance, and they say they’ve reached a point where the statistical significance is such that, were they trying to prove anything else, it would count as a formal scientific discovery. But, whatever may be the result, they are not able to back up the fact with any scientific evidence.
Nobody, least of all the researchers involved, is ready to call the Standard Model’s upper speed limit busted just yet. But as they do not have any scientific proof to what happened, they are ready t share their new discovery to a wider scientific community. As this new phenomenon has been taken seriously by all researchers around the globe, we will have to wait and see if anyone can produce a satisfactory answer.

Leaked Gas Detector

Description:


As shown by the gas sensor alarm QM, buck rectifier and regulator circuits, integrated circuits KD28, speaker Y and so on. QM gas sensor for the QM-N5 type. Step-down transformer rectifier and regulator circuit consists of B, the bridge's rectifier D1 ~ D4, C1, C2, integrated voltage regulator 7806 and so on.
Work, adjustment potentiometer W, the power for 1 minute. When the air is clean, QM corresponds to a larger resistance value, W the partial pressure is small, so that the KD28 reset the alarm does not occur. When a combustible gas when contact with QM, QM corresponds to the resistance value is small, W partial pressure on the larger, so KD28 set, the 3 foot high output speaker to promote the work of an alarm signal. Gas left the circuit will resume normal operation.
