Latest 10 Inventions in computer science
About computer science

Computer science or computing science (abbreviated CS or CompSci) designates the scientific and mathematical approach in computing. A computer scientist is a person who does work at a professional level in computer science and/or has attained a degree in computer science or a related field.

Its subfields can be divided into practical techniques for its implementation and application in computer systems and purely theoretical areas. Some, such as computational complexity theory, which studies fundamental properties of computational problems, are highly abstract, while others, such as computer graphics, emphasize real-world applications. Still others focus on the challenges in implementing computations. For example, programming language theory studies approaches to description of computations, while the study of computer programming itself investigates various aspects of the use of programming languages and complex systems, and human-computer interaction focuses on the challenges in making computers and computations useful, usable, and universally accessible to humans.

Latest Inventions in computer science 

Washing machine that does not need water

British company Xeros looks forward to conquer the American market with its latest invention, a new washing system able to save a lot of water using nylon beads. The beads tumble wash clothes using 90 percent less water than traditional washers.

In addition, the company's latest invention, which is currently in the development stage, requires less detergent. Xeros claims that there would be no need for tumble drying and if the homes in the United States would switch to the new system, the emissions of carbon dioxide would be considerably reduced. The result would be as though 5 million vehicles have been removed from the road. The company also says that the new washing machine will save 1.2 billion tons of water each year, which equals 17 million swimming pools.

The washing machine does its job using small nylon beads that eliminate stains off clothes and lock them into the molecular structure of the nylon. The beads can be used for hundreds of washes and afterwards they can be easily recycled. The technology behind the new washing machine is the result of a research carried out at the University of Leeds. It has been used in a concept washing machine by the Cambridge Consultants.

After carrying out tests for over three years, Xeros, a spinout from the University, managed to achieve an agreement with Kansas City-based GreenEarth Cleaning, which intends to market Xeros' latest invention across North American continent in 2010. 

Technology that Scan,s user ear to avoid theft

Researchers managed to come up with a technology that could protect portable devices such as iPod and mobile phones from theft.

Their latest invention uses the acoustic fingerprint of the ear, which makes it impossible for other people to operate the device. Such technology could be also used to improve the safety features of bank accounts and passports.

Scientists found that it is possible to identify a person by the distinctive sounds of the ear chamber. In their study researchers used an earphone to send a weak tone in the ear in order to stimulate hair cells beyond the inner ear. Thus they hoped to make the hair cells produce their own sound. The sound is unique, with the person's eardrum, ear bones and ear shape playing a role in producing it.

The latest invention proposed by the researchers will allow a user's iPod or mobile phone to instantly identify the "fingerprint" of the owner. Thus with the help of anti-theft acoustic fingerprint detector people will have the possibility to use their gadgets without worrying that it could be stolen.

Such technology could be used to pay bills or safely carry out different banking transactions by simply put on a set of headphones or a mobile phone to the ear. According to Arthur Rapos, electronics engineer at Elektra company, this technology could be a step towards creating microchips with biological information that could be implanted in humans.

System that converts energy from tramping feet into electricity

British scientists are working on their latest invention - a system able to use the "boot force" in order to power various electronic tools, including torches and radios used by military troops. The system would make the backpacks of soldiers considerably lighter. The devices currently developed by experts from the University of Leeds will generate electricity from the energy of flexing knees and tramping feet.

Their latest invention will eliminate the necessity to carry heavy batteries, thus reducing the weight of soldier's backpacks by up to 10 kilograms (a typical backpack weights about 75kg). The latest invention developed by the British scientists takes advantage of high-tech piezoelectric transducers that produce electrical energy from mechanical stress. Besides the technology is eco-friendly. 

The system, which is part of "battery free soldier" program, represents a two-year project supported by the Engineering and Physical Sciences Research Council (EPSRC) and the Defense Science and Technology Laboratory (DSTL). Researchers look forward to create similar technologies based on other alternative sources, such as solar power and body heat.

Cell Phone with Portable Microscope for Spotting and Tracking Diseases

A team of scientists from the United States developed a portable microscope that is connected to a camera phone. Their latest invention thus can be used to diagnose dangerous diseases in blood and sputum samples, the latter are obtained by coughing deeply, which allows expelling the substance from the lungs into a sterile cup.

It is worth mentioning that light microscopy is a very important tool that can be used to diagnose malaria, tuberculosis and other dangerous diseases. The digital images of cell samples, taken by camera-equipped lab microscopes can be transmitted via Internet to specialists at different health centers for additional studies.

Together with his colleagues from the University of California in San Francisco, Daniel Fletcher at the University of California in Berkeley, though about exploiting the already existing technologies, widely used by people in everyday lives, such as cell phones, for medical reasons.

In this image you can see malaria-infected blood. According to one of the latest UN reports, about 60 percent of people around the globe use cell phones. The team realized that cell phone networks represent an inexpensive and fast way to convey medical information wirelessly. For their latest invention scientists used off-the-shelf parts to create an inexpensive and portable microscope attachment which connects to a Nokia N73 phone camera.

Using microscope, researchers can identify objects that are only 1.2 micrometers across. Red blood cells are usually from 6 to 8 micrometers across. In order to take clear picture of medical sample natural light is quite enough. Still, scientists decided to add a battery-powered LED lamp and several filters so their gadget could also work as a fluorescent microscope, reports New Scientist.

Researchers tested their latest invention against several widespread diseases and conditions. They found the results promising, saying that pictures of malaria-infected blood were good enough to be able to diagnose the disease. Besides, the system could also help diagnose sickle-cell anaemia from blood samples, thus researchers will be able to spot the presence of tuberculosis.

"Cell counting is the main thing we have done. Additional things could include annotating an image to point out a problem or a question to be answered by a doctor at a central hospital," says Fletcher. Using the device combined with detailed information about the patient and location, could help track the spread of dangerous diseases.

Gadget that Translates Dog's Language

Want to understand what your dog is barking? For the first time presented in 2002, the Bowlingual comes back, the gadget examines a dog's bark and then identifies its emotion. The latest invention was developed by toymaker Takara Tomy, which looks forward to present the toy in August. Currently the gadget is expected to be sold only in Japan.

It is worth mentioning that Takara Tomy's latest invention was initially developed by an audio researcher and a veterinarian. The goal was to study and then convey the sound of a dog's bark. The company claims that its new device is able to identify and interpret six basic emotions.

The first version featured a microphone that had to be worn around a dog's neck. There was also a handheld unit that read the information sent from the microphone. The unit then identified the dog's emotion and showed the corresponding information on its screen. The current invention includes a more compact unit that incorporates a speech synthesizer that audibly informs you about the things your pet attempts to communicate. The unit also shows the information on the screen. You can find more curious and interesting latest inventions here at www.infoniac.com; please consider checking the links at the bottom of the story.

If the user wants to analyze the information later, they can save it. This latest invention also features an answering machine function, which allows the user to track the dog's feelings when the owner is away. It is worth mentioning that in 2002, when the invention was introduced, the Time Magazine marked it as a "Best Invention of 2002." Takara Tomy even gave several Bowlinguals to Vladimir Putin for his dogs.

Up till now there has been no information about the release date of new Bowlingual in the United States. When it hit the stores in Japan, the gadget will cost about $220.

Latest Invention: Synthetic Tree to Collect Huge Amounts of CO2

The latest invention of researchers from Columbia University is an artificial tree that is able to capture carbon dioxide a thousand times faster that a real tree. The lead researcher and a professor of geophysics at Columbia University, Klaus Lackner, has been developing the project for over 10 years and holds hope that the artificial tree will be a very important tool for tackling climate change.

Scientists will use their latest invention to trap greenhouse gas emitted by vehicles or airplanes. The synthetic tree, which resembles a cylinder, will not require direct sunlight, water of branches to work properly. According to Lackner, the tree is flexible in size and can be placed almost anywhere.

Here's how it works: the synthetic tree gathers the greenhouse gas on a sorbent, cleans and pressures the carbon dioxide and then releases it. The technique of gas absorption resembles that of a sponge that collects water.

During a whole day one artificial tree will be able to collect one ton of CO2, which equals to the amount of carbon dioxide emitted by 20 cars. The technology is currently in the development stage at Global Research Technologies, a company based in Tucson, Arizona, co-founded by Lackner, who at the moment is its chairman. Such invention might serve well for the environment by it is quite costly - each synthetic tree requires $30,000 to make, reports CNN.

Data presented by the U.S. Department of Transportation shows that currently in the United States there are about 135,932,930 vehicles, which means that in order to absorb the amount of carbon emitted by these cars, the country would need to "plant" 6.8 million synthetic trees (that's $204 billion). With the current global economic crisis the project will probably remain in the development stage for some time. Still, Lackner and his team look forward to push their latest invention full-force. The researcher managed to arrange a meeting with U.S. Energy Secretary Steven Chu to talk about the concept.

Robot that Writes Prescriptions and Doles Out Drugs

Japanese tech giant Panasonic recently unveiled its latest invention - a robot able to distribute drugs to patients. In addition, according to a Japanese online news source, the robot will have the ability to complete prescriptions. Nikkei Net reports that Panasonic's latest invention will hit the market in a few months.

To be able to write prescriptions and dole out drugs, engineers will connect the machine to electronic medical online records. Thus the robot will scuttle across Japanese hospitals and pick prescriptions for the patients. For the past several years Japanese researchers managed to create a wide range of robots that are already helping people around the world; at infoniac.com you can find more news on robots and a wide list of latest inventions.

Panasonic looks forward to sell its latest invention in Europe and the United States as well. Besides, the company has plans to create other medical robots.
