  • Patent number: 5387943
    Abstract: A semiautomatic lip sync recovery system for time synchronizing the audio and video channels of a television signal uses programmable delay circuits in each channel. An area of the image represented by the video channel is defined within which motion related to sound occurs. Motion vectors are generated for the defined area, and correlated with the levels of the audio channel to determine a time difference between the video and audio channels. The time difference is then used to compute delay control signals for the programmable delay circuits so that the video and audio channels are in time synchronization.

  • Patent number: 5276839
    Abstract: An EEPROM programming circuit is disclosed which provides for the on-board rogramming of a EEPROM memory using:a microprocessor, a bootstrap ROM, a UART communications port, and a Eccles-Jordan flip flop switch system. These elements are electrically connected to a host system and the EEPROM by a central data bus. In normal operation, the host system sends a first set of data signals through the circuit to the EEPROM, which produces a set of processed signals. In operation in the programming mode the host system sends a second set of data signals to cause the microprocessor to send a switch signal to the Eccles-Jordan flip flop switch and to the bootstrap ROM. The bootstrap ROM contains the program code that forms the programs that are used to program the EEPROM.

  • Patent number: 4343409
    Abstract: A unitary reservoir (100) in FIG. 1 made of plastic, preferably made by blow molding, comprises a plurality of hollow bulbs (110), (140) and (170) with centers along a curved line in a plane, at least one bulb being a mounting bulb (140) having a mounting tower (144) or (176) extending from said bulb, said mounting tower comprising a solid portion enabling mounting of the reservoir (100) and a hollow portion that communicates with the interior of said mounting bulb and acting to resist bending of the solid portion.
