These pointing and navigation disk devices are built to enhance handheld devices. They use an electrically-variable resistive rubber sensor, along with simple plastic components mechanical design geometries and a sophisticated firmware algorithm. These parts all work together to translate user motion on the actuators in two different dimensions on a circular sensing element. They come in 360-degree or N-way full-variable speed analog control. The electrical interface is received through five standard GPIOs and emitted through an 8-bit analog-to-digital converter. It needs 8-bit support or extra processors when employing I2C, PS2, UART or SPE interfaces. It's designed to last through more than 3 million life cycles. It comes in standard reference design (straight drop in), module design (reference design with customized actuator and without PCB), or fully custom solutions.
More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
