TakkTile turns digital barometers into open-source robot touch sensors
Freescale Semiconductor's MPL115A2 is a tiny thing that will sit quite comfortably on the tip of your finger. It's hard not to marvel at the engineering that went into the creation of something so small, yet so sensitive. The little metal square is minute enough to be plunked into a cell phone, offering up location pinpointing technologies that supplement GPS, gauging positions based on changes in atmospheric pressure. Harvard's Biorobotics team was clearly impressed when it discovered the technology, devising a fascinating implementation that extends beyond the walls of the cell phone. The sensors would go on to form the core of the department's TakkTile open-source boards capable of bringing sensitive touch sensing to robot hands. The I2C bus / USB-compatible boards incorporate several of the sensors, with the whole thing covered in 6mm of rubber, to help protect them. The rubber lends some durability to the TakkTile -- in fact, if you click on after the break, you can see footage of the team placing a 25 pound dumbbell on the board and banging it with a hammer (which seems to be a fairly popular activity over there). Even with that extra layer, the TakkTile is still quite sensitive -- as evidenced by the five gram weight in the video. In fact, it's even possible to get it to detect a pulse by placing it against your wrist, though the team was unable to recreate that during our visit. Also compelling is the price -- bought in bulk, the tiny barometers will run you $1 a piece, making the tactile array relatively inexpensive to assemble. Once you buy one, you can also get the most bang for your buck by snapping off the rows for individual use, a possibility given the symmetry of the design. Or you can just make one yourself, as the department has opted to open-source the technology, to help make it even more readily accessible to interested parties.%Gallery-161777%
Freescale joins ARM A5 and M4 cores at the hip for performance and power savings
You may have noticed a trend recently -- pairing slightly less powerful cores that sip power, with more robust ones that can chug through demanding applications. NVIDIA's Tegra 3 will be packing an underclocked fifth core, while ARM's big.LITTLE initiative matches a highly efficient 28nm A7 with the beefy A15. Now Freescale is planning to use the same trick, but you won't find its asymmetrical CPUs in your next tablet or smartphone. Its platform, which marries a Cortex M4 to a Cortex A5, isn't meant to compete with the latest Snapdragon. These chips will find homes in factories and in-dash infotainment systems which have increasingly sophisticated UIs, but don't need to push thousands of polygons. Software development tools will land before this quarter is out and the first batch of silicon will be announced in Q1 of 2012. Looks like the era of "dual-core" meaning two identical cores has officially come to an end.
Apple acquires over 200 Freescale Semiconductor patents
Patently O has discovered that Apple purchased over 200 patents from Freescale Semiconductor on April 11 of this year. However, the patent purchase was not disclosed until May 18. Freescale Semiconductor was formerly Motorola's Semiconductor Product Sector until the electronics giant spun off the company in 2003. Details of the patent purchase are unclear. Patently O says it's likely that Apple made a cash purchase of the patents and that there is a large diversity among the group of patents, although almost all relate to computer hardware and wireless devices. As always with patent purchases, Apple may never actually implement the patented technologies in its devices. Apple may have purchased the patents to use as leverage in future patent lawsuits, or to stave off those lawsuits.
Freescale Semiconductor and RealD working to improve active shutter 3D
Passive 3D seems to be the new home entertainment hotness at CES this year, but that doesn't mean the industry has given up on active shutter. Case in point, Freescale Semiconductor and RealD have announced they're developing an "enhanced 3D active eyewear solution" that combines Freescale's RF4CE platform for the over-the-air 3D synchronization with RealD's switching, filtering, and optical technology. Powered by Freescale's MC1323x System on a Chip, the new system hopes to eliminate many the problems plaguing IR-based active shutter like line-of-sight and of field-of-vision limitations. It should also allow 3D glasses to operate from longer distances, and since it takes advantage of the same radio frequency used by remotes, it could lower overall costs for manufacturers to boot. Keep in mind though that unlike NVIDIA's RF-based 3D Vision Pro Tech, all of these wondrous promises are just talk with no walk -- so we'll throttle our excitement until we can go eyes-on with some actual gear. For all the details hit up the PR after the break.
Freescale's 7-inch tablet runs Android, Chromium OS or Linux, costs $200 (video)
Remember the $200 smartbook reference design that we saw at CES this year? Well, it's back, it's holding on to that same price and 7-inch enclosure, but this time it's also showing off an expanded OS compatibility. Adapting the open source Chromium OS and another Linux variant to the ARM architecture of the prototype device was apparently not much of a hurdle for Freescale, who has an Android option in the works as well and claims to be just optimizing and enhancing the user experience at this point. Presumably one of the enhancements will be the installation of a capacitive touchscreen as the present demonstration requires either a mouse and keyboard or a resistive torture test to operate, but we'll accept the company's explanation that this is just a proof of concept and not the final product. Slide past the break to see some HTML5 video running on this bargain bin tablet, and hope that your friendly neighborhood OEM picks these designs up for some retail action.
Samsung, Freescale partner on white LEDs to go green
With the growing emphasis on ROHS (reduction of hazardous substances) and energy efficiency in the electronics industry, it's no wonder that LEDs are replacing fluorescent lamps for backlighting LCDs. So expect to see more partnerships like the one that Samsung and Freescale Semiconductor just entered into, with Samsung providing the glass (and some sweet moolah for custom parts) and Freescale bringing its LED drivers to the party. Heck, we figure even the cheaper white LEDs make it easier to achieve uniform illumination across the screen and higher contrast ratios, which get high marks around the Engadget HD offices; for folks not obsessed with picture quality (yeah, they're out there), LEDs offer up lighter and thinner displays.
