  • Synchronous demodulation with precision track-and-hold circuit
    Patent number: 7384066
    Abstract: A synchronous demodulation circuit uses a digitally controlled track-and-hold circuit to capture the peak amplitude of a rectified signal. A microcontroller controls the track-and-hold circuit. In particular, the microcontroller controls a hold mode of the track-and-hold circuit to capture the peak amplitude of the rectified signal.

  • High corrosion resistance aluminum alloy
    Patent number: 6733726
    Abstract: An aluminum-based die casting alloy exhibiting improved corrosion resistance and good die-castability contains from about 4.5 to about 12 percent silicon by weight, at least 87 percent aluminum by weight, from about 0.25 percent to about 0.6 percent manganese by weight, and a maximum of 0.2 percent copper by weight. The alloys preferably contain iron in an amount sufficient to improve hot tear resistance and to decrease the tendency for die sticking or soldering during die casting.
