  • Publication number: 20070037538
    Abstract: A technique for reducing multipath distortion in an FM receiver, with a plurality of switchable antennas, provides a fast distortion detector that monitors a received signal for significant distortion events of less than about 15 microseconds in duration. In response to a multipath event, the output of the fast distortion detector initiates a search for a lower distortion (better quality) antenna. To prevent frequent antenna searches from causing an audible disturbance, a threshold is introduced to desensitize the fast distortion detector. Threshold decay is a function of an overall received RF signal level. A slow distortion detector is also provided that measures distortions of the received signal relating to signal quality.

  • Patent number: 6207033
    Abstract: A process for the regeneration of a plating bath comprising trivalent chromium involves the use of platinum anode and a copper cathode wherein the anode to cathode ratio is greater than 2:1 upon passage of a charge having a current density of at least 10 Amperes/diameter2 of exposed cathode. An apparatus for conducting the process is also disclosed. The described process obviates the need for an ion exchange resin and is conducted without the formation of any deleterious toxic sludge.
