Milwaukee—The good guys have another weapon in the battle against car thieves—an anti-theft car battery. While the idea of a battery with security features may at first seem far-fetched, without electrical power no car goes anywhere.
Johnson Controls makes the DieHard Security™ Battery for Sears. The sealed plastic security module on top of the battery consists of an electronic circuit board interfaced with a Deltrol Controls 200A multipole relay. When the battery is armed, the car won't start because the electronic module opens the relay, disconnecting the battery, and grounds the ignition, stalling the engine. When purchased, the battery is matched to a pair of key fob transmitters that arm and disarm it.
Because of the Battery Council International cold cranking requirements for the battery, the relay needs to be extremely robust—capable of handling 900A transient current at 12V dc with low contact resistance (less than 0.2 mV) for good current flow—while fitting in a compact volume and having automotive standards lifetime.
"The unique combination of patent-pending relay contactor and solenoid actuator in a compact package is the technology that makes the relay possible," says John Wittmann, Deltrol VP and engineer.
Jim Symanski, program manager at Johnson Controls Automotive Systems Group adds that, "The Deltrol relay was a key enabling technology with excellent performance and reliability in the compact size that we required."
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
With LEDs dropping in price virtually every year, automakers have begun employing them, not only on luxury vehicles, but on entry-level models, as well.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
