With the introduction of the MC34940 sensor, Freescale expanded its line of electric-field (E-field) ICs beyond its current crop of automotive sensors to encompass appliances and industrial control panels. The single-chip IC generates a low-level electric field and then detects changes in that field and therefore, in essence, is a capacitance-based sensor. The new model offers a 33 percent smaller package size than some earlier versions and incorporates a bigger pitch for easier assembly. It can be used for proximity detection and three-dimensional E-field sensing. It can also trigger functions, such as turning switches on or off, or setting off alarms to indicate dangerous situations for devices such as coffee pots, hair dryers and lawn mowers.

Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
The DDV-IP is a two-wheeled self-balancing robot that can deliver cold beverages to thirsty folks on hot summer days. A wireless RF remote enables manual control of the device beyond the act of self-balancing. All of the features of the DDV-IP result in an effective delivery vehicle while providing entertainment to the user.
Eric Doster of iFixit talks about the most surprising aspect of the Microsoft Surface Pro 3 teardown. In a presentation at Medical Design & Manufacturing Midwest, iFixit gave the Surface Pro 3 a score of one (out of a possible 10) for repairability.
