Patent CA-2264786-A1 (CA)
Title: System and method for controlling an active matrix display
Inventor: COSTA VICTOR M DA
IPC: G09G3/20
Filed: 1997-08-27
Abstract: A smart controller chip for controlling an active matrix display. Within the controller chip, circuitry for generating analog reference levels is incorporated alongside circuitry for generating digital timing and control signals. The combination of D/A analog circuitry and standard digital logic makes the controller uniquely suited for addressing all the panel control needs both for the normal digital functions but also for control of the analog aspects of the panel, like display gamma. The analog reference levels and the digital signals are made programmable using registers internal to the controller chip. The contents of these registers are programmed initially by digital values stored in an external PROM or in flash memory integrated into the controller chip. In addition, software in a host system is able to program these registers via an interface between the host system and the controller chip.

Abstract: A method and apparatus for chroma keying filtered textures are provided. Chroma keying is performed which replaces the input texel color with a new color if the input texel color matches the chroma color. The chroma key circuitry (149) keeps the input texel color and sets the alpha component to 1 if the input texel color does not match the chroma color. The chroma keyed texels are filtered using bilinear filtering (150). The color components of the filtered texels are fogged (152) using a fog factor, a fog color, and the alpha component of the filtered texel. The fogged and filtered signal is blended (154) with a background color to produce an output color for the texels.

Title: Method of ammonium sulfate purification
Inventor: HANTKE MARK
IPC: C01D7/02
Filed: 1999-09-29
Abstract: A process for synthesizing ammonium sulfate and United States Pharmacopoeia grade sodium bicarbonate. The process allows an energy efficient conversion of precursor sodium sulfate and bicarbonate to ammonium sulfate high grade fertilizer and the pharmaceutical grade sodium bicarbonate by saturation of process brine with sodium sulfate. This step was previously unrecognized in the art, which resulted in prior art methods being ineffectual from engineering, energy and product quality points of view. The present process reintroduces sodium sulfate into the process brine or solution to perpetuate the conversion process in the absence of separation problems and energy expenditures inherent in the prior art techniques.

Patent CA-2298929-A1 (CA)
Inventor: LEMAY NORMAND T JR
IPC: G05F1/567
Filed: 2000-02-17
Abstract: The invention includes a temperature compensated constant current source. Specifically, two PNP transistors are implemented in a circuit wherein one of the transistors is used to provide a DC feedback to the other transistor to stabilize the output current. Temperature independence is effected due to the base emitter saturation voltage occurring when the emitter resistance is equal to the collector resistance at large values for .beta., the common emitter current gain. The circuit provides a stable constant current source independent of temperature variations.
