Filed:

Jul 30, 2001

Appl. No.:

09/919528

Inventors:

William Hays - Oceanside CA, US
Claudio Laraia - Bronx NY, US

International Classification:

H04N005/44

US Classification:

348/837000

Abstract:

A mobile video-audio switching system mounted in a motor vehicle powered by the vehicle's 12V DC battery. A mobile video-audio switch(MVAS) device is mounted in the motor vehicle and it has four different video-audio input devices electrically connected thereto and four liquid crystal display(LCD) screens are also mounted in the motor vehicle. Four separate wireless remote control transmitters send individual signals to the MVAS device directing that signals from any of the different video-audio input devices be sent to any of the individual LCD screens. Individuals viewing the respective LCD screens can receive an audio input through a headset that they may wear or they may receive the audio signals through the radio and speaker system already installed in the motor vehicle.

Abstract:

A reduced-area, read-only memory, including a programmable read-only memory, accomplished with a first step of removing one word address line from the word decoder input and one bit address line from the bit decoder input. The number of decoder output lines is thus cut in half. Adjacent line-driving transistors are driven by the same decoder output line. The removed word decoder input, and its complement, drive auxiliary bit lines; the removed bit decoder input and its complement drive auxiliary word lines. Circuitry connected at crossovers of word lines with auxiliary bit lines and bit lines with auxiliary word lines selectively suppress the selection of one line of each pair of lines that is driven by a single decoder output. The invention is particularly effective when utilized with Schottky diodes insulated from the semiconductor substrate. In the memory cells the Schottky diodes can be connected in series with voltage-programmable resistors to provide a reduced-area, programmable, read-only memory.
