New York, June 19 (IANS) US tech giant IBM has patented an eye wear like Google Glass that will have red-eyed night vision capabilities, a media report said. Although not promising a true night vision, the device is described in the patent to improve sight under low light by tricking the brain to focus on high contrast imagery. "IBM's Google Glass modifications include a sensor and 'a comparator device' designed to detect and contrast light intensity. When the light intensity drops below a set level, a pair of projectors -- one for each eye -- bathe the user's eyes in red light," a report in International Business Times (UK) said. The patent claims the effect is similar to that of dark rooms used in photography or the red-tinted glasses worn by some airline pilots. Dark environment with a red tinge cause the rod cells, which are the photoreceptors in our eye, to send high contrast images to the brain. When the user enters a low-light environment, the projector automatically projects a low-level red light in to each eye of the user. Shining red light directly into the eyes creates the same response rods as casting red light onto an environment. Which means it tricks the rod cells into sending higher contrast images to the brain. However, the company also issued a health warning. The patent read: "The wearer of current glasses such as Google Glass is subject to the risk of a phenomena referred to as binocular rivalry and phoria -- a latent deviation or misalignment of the eyes that appears when both eyes are no longer looking at the same object."​

​London, June 16 (IANS) Planning to buy a new smartphone? Remember that the device may lose half of its value in a month which is even faster than your car, says an interesting study. While cars typically lost 20 per cent of their value a year after being driven off, money-draining smartphones went down up to 65 per cent of their value in just a month of being released, musicMagpie.co.uk reported on Thursday. The findings showed that only iPhones could retain their value much better than android-based devices. While the iPhone 4 continues to retain 39 per cent of its value even five years after its launch, the iPhone 6 (16 GB) has managed to keep 50 per cent of its 539 British pounds market value a year after its release. However, iPhone 5 showed a significant depreciation, losing 66 per cent of its value after eight months, the report stated. The highly anticipated Samsung Galaxy S4, which released in 2014 lost half of its value within two months of appearing on the market. That's nearly a £300 loss off its original selling price of £579, the study said. HTC One M9 has suffered the worst in the android sector. It was sold for 579 British pounds when released in March 2015 but lost a staggering 65 per cent of its value in just a month. Phones go down in value because better, faster and technologically superior models replace them. Demand for a certain phone model can also affect its popularity and consequently depreciate its value, the report concluded.​
