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.

A few weeks ago, Ford Motor Co. quietly announced that it was rolling out a new wrinkle to the powerful safety feature called stability control, adding even more lifesaving potential to a technology that has already been very successful.
It won't be too much longer and hardware design, as we used to know it, will be remembered alongside the slide rule and the Karnaugh map. You will need to move beyond those familiar bits and bytes into the new world of software centric design.
People who want to take advantage of solar energy in their homes no longer need to install a bolt-on solar-panel system atop their houses -- they can integrate solar-energy-harvesting shingles directing into an existing or new roof instead.
