Title: Master slave critical conduction mode power converter
Inventor: JANSEN ARIAN
IPC: G05F1/10
Filed: 2005-09-07
Abstract: A system and a method for to use multiple power sources for supplying power to a load. The system and method use a triggering system to automatically and substantially cancel a ripple component of the input current drawn by the system. A master power source and a slave power source supply power to the load. The triggering system results in the two power sources having switching frequencies that are substantially equal and switching cycles that are substantially 180° out of phase. Further, the method and the device contemplate the use of a local oscillator in the triggering system to ensure that the slave power source is triggered to the on position at a point in the switching cycle of the master power source that is approximately 180° out of phase with a leading edge of the master switching drive signal. The system and method are advantageously used to provide a power factor correction front-end for a switch-mode power supply. Power supplies with a diverse array of relationships between power supplied and switching frequency can be used.

Title: Methods and apparatus to insure correct predecode
Inventor: BRIDGES JEFFREY TODD
IPC: G06F9/45
Filed: 2006-02-24
Abstract: Techniques for ensuring a synchronized predecoding of an instruction string are disclosed. The instruction string contains instructions from a variable length instruction set and embedded data. One technique includes defining a granule to be equal to the smallest length instruction in the instruction set and defining the number of granules that compose the longest length instruction in the instruction set to be MAX. The technique further includes determining the end of an embedded data segment, when a program is compiled or assembled into the instruction string and inserting a padding of length, MAX -1, into the instruction string to the end of the embedded data. Upon predecoding of the padded instruction string, a predecoder maintains synchronization with the instructions in the padded instruction string even if embedded data is coincidentally encoded to resemble an existing instruction in the variable length instruction set.

Title: Generating locally decoded picture using crc
Inventor: JEBB TIMOTHY RALPH
IPC: H04N19/89
Filed: 2006-06-01
Abstract: A video signal is coded by generating, at a transmitter, a difference signal (at 2) representing the differences between a picture to be transmitted and a predicted picture based on a stored locally decoded picture. This is decoded (5, 6) to generate a fresh locally decoded picture. The transmitter also generates a check signal, such as a CRC, as a function of the locally decoded picture. The receiver decodes the difference signal to create a decoded picture. It compares the decoded picture with the check signal, and generates an error signal if the two do not tally.
