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.
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
