Video Protection Circuit Providing Short To Battery Protection While Maintaining Termination Impedance

US Patent:
7193828, Mar 20, 2007
Filed:
Sep 11, 2003
Appl. No.:
10/659836
Inventors:
Paul F. L. Weindorf - Novi MI, US
Mark A. Leinonen - Livonia MI, US
Assignee:
Visteon Global Technologies, Inc. - Van Buren Township MI
International Classification:
H02H 3/20
US Classification:
361 915
Abstract:
The present invention provides for a transistor in series with the video input of a video input device prior to the termination resistor. The transistor is utilized due to the large amount of power that would be dissipated across the termination resistor if the video input was inadvertently connected to the automotive battery voltage. For the typical automotive battery of 14 volts, approximately 2. 6 watts would be dissipated over the termination resistor likely causing a failure in the video input device. An N channel MOSFET can be used as the switch to provide an extremely low series resistance compared to the 75 ohm termination resistor. This low series resistance minimizes video signal degradation which would be caused by higher impedance switches due to the voltage divider formed by the switch impedance and the 75 ohm termination resistor. An N channel MOSFET also provides fast switching speeds and can be selected to minimize parasitic capacitances such that the video signal is not degraded due to the 75 ohm source impedance.

Automotive Entertainment System For Rear Seat Passengers

US Patent:
6330337, Dec 11, 2001
Filed:
Jan 19, 2000
Appl. No.:
9/487054
Inventors:
Sterling Christpher Nicholson - Waterford MI
Dennis Allen - Southfield MI
Mark Alan Leinonen - Livonia MI
Daniel Jon Lebioda - Canton MI
John Michael Dicky - Dearborn MI
Assignee:
Visteon Global Technologies, Inc. - Dearborn MI
International Classification:
H04B 100
US Classification:
381 86
Abstract:
An automotive multimedia entertainment system includes an integrated rear seat entertainment module in which audio signals coordinated with video entertainment devices in the rear seat can be reproduced using the vehicle's audio system. Multiplex control signals between an audio main control unit, rear seat entertainment module, and CD disc jockey allows free selection of sources for single and dual play modes. By sharing an external audio input of the main control unit, between the rear seat entertainment module and the CD disc jockey, a single version of the main control unit can be used in vehicles either with or without rear seat entertainment modules or CD disc jockeys.
