Toshiba America Electronic Components Inc. (TAEC) has released three high-voltage three-phase motor drivers with built-in power management circuits. The circuits were designed for direct current brushless motors, air conditioner fans and pump motors. Developed by Toshiba Corp., the TPD4104K, TPD4111K and TDP4112K single- chip inverter ICs are manufactured using high-voltage silicon on insulator trench isolation process.
The motor drivers were created to help with energy savings. “A growing number of home appliances and industrial products are employing dc motors and inverters that take lower power consumption and protection of the global environment into account,” says Ajay Chinai, business development manager, discrete products for TAEC. “With these devices, Toshiba is responding to industry demand for higher power, faster response time and higher levels of integration, all in a small structure.”
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
