Planetary wheel failure was a vexing issue for the U.S. Marine Corps.’ Light Armored Vehicles, partially because these failures couldn’t be predicted. Wireless temperature and vibration sensors from Solidica Inc. of Ann Arbor, MI, made it possible to monitor the wheels without the difficult task of routing wires through the water-tight hull. The Solo sensor device, which includes a Freescale Semiconductor MMA7260QT accelerometer, dynamically monitors both temperature and vibration. Wireless communication also lets the USMC alter the embedded algorithms as the vehicles move into different operational environments and has built-in signal conditioning and alert prognostic algorithms. Ruggedization is a key factor, since the sensors get drenched when the vehicles drive through water.
The Beam Store from Suitable Technologies is managed by remote workers from places as diverse as New York and Sydney, Australia. Employees attend to store visitors through Beam Smart Presence Systems (SPSs) from the company. The systems combine mobility and video conferencing and allow people to communicate directly from a remote location via a screen as well as move around as if they are actually in the room.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
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.
