NEW STEERING DEVICE TO AVOID ACCIDENTS

An innovative new steering device that could help prevent hazards like rear-end collisions and rollovers caused by panic over-steering has been developed. It can take up to two and a half turns to steer a modern vehicle. While turning, the driver must release the wheel in the necessary hand-over-hand movement, which is unsafe. In the upcoming Human Factors and Ergonomics Society (HFES) 2013 Annual Meeting, Rene Guerster will propose an alternative steering device that could help to prevent hazards such as rear-end collisions and rollovers caused by panic over-steering. Severe sudden turns are extremely difficult with today's steering systems, researchers said. Developing what he terms "computer-mediated steering," Guerster believes his proposed technology, already common in engine controls, would enable steering around a suddenly-appearing obstacle without hand-over-hand fumbling. Guerster's yoke-like device, currently in the concept stage, requires only a quarter turn in either direction from the straight-ahead position, enabling the driver to keep his or her hands in the same position on the device at all times. A computer would record the degree to which the device is turned, the speed at which it is being turned, and the vehicle speed. It would determine how far the front wheels should be turned and then turn them via an electric motor, whether the driver is parallel parking, performing a gentle lane-change manoeuvre at high speed, or turning suddenly to avoid a pedestrian. "The likelihood of intuitive, safe use of this device will be studied in experiments to be conducted in the future. If computer-mediated steering shows benefits, this is easy to engineer into modern vehicles," Guerster said.

MUNSHI PREMCHAND STORIES IN COMIC FORMAT

Stories by modern Hindi and Urdu literary legend, Munshi Premchand are now available in comic format published by Amar Chitra Katha. The comic books in Hindi detailing two stories by the late literary phenomenon, is part of the publisher's contemporary classics section, which began in 2012 with stories by author Ruskin Bond. "We are launching the comics at the World Book Fair and it is our tribute to Premchand. The idea is to make his stories familiar with children," Reena Puri, Editor, Amar Chitra Katha told PTI. The stories "Buddhi Kaki" (The old Aunt) and "Do Bail" (Two Oxen) have been scripted and illustrated by Pratima Singh and Surendra Murthy.

WORLD's FIRST UNDERWORLD TENNIS COURT IN DUBAI

Dubai, which boasts of the world's highest tennis court, may also become home to the first underwater tennis centre where spectators can watch games from below or above the sea life through a massive glass dome. Krzysztof Kotala, a Polish architect who owns a studio in Warsaw, is currently seeking investment from local players to make the ambitious project a reality. Interestingly, the proposed location for the project (arguably one of the world's lowest tennis courts) is just next door to the highest tennis court atop the Burj al Arab skyscraper in Dubai. "There is not an investor but I would like to get interest (from them) as I think it is a good idea," Kotala, 30, was quoted as saying by a local magazine. When asked why he chose Dubai for his project, Kotala said the Gulf city had a rich tradition of tennis. "This will be something original. This should be somewhere where there is the tradition of tennis. Dubai is perfect for this idea," he said. The in…

DEADLY HABIT...MOBILE CALL ANSWERING ON DRIVE

Nearly 60 per cent of two-wheeler users "instinctively" answer mobile phones on ride while 14 per cent of pedestrians click selfies crossing the road, finds out a survey. Sixty four per cent pedestrians regularly do this and 18 per cent immediately respond to a call from their superior at work, even while switching sides on the road. That is only one part of the story. One in every three car drivers tends to send out an important text message, stated the survey conducted by consumer goods maker Samsung across 12 cities in India. There is one road accident in every four minutes in India, it added, citing government data. "11 per cent of two-wheeler riders would always answer their phone when on the road, regardless of who was calling, 30 per cent would respond to calls from family while 18 per cent of the riders responded to work-related calls," it added. In addition, 23 per cent of two-wheeler riders admitted to reading and replying to texts or social media updates…
