Abstract: A head up display arrangement for a motor vehicle includes a source of a first video signal. A driver monitor system detects a location of at least a portion of a human driver of the motor vehicle. An electronic processor is communicatively coupled to the first video signal source and to the driver monitor system. The electronic processor produces a second video signal that is dependent upon the first video signal and that includes parallax information. The parallax information is based on the detected location of the portion of the driver. A head up display projection device produces a virtual image that is visible to the driver and that is based upon the second video signal.

Abstract: A method for approximating mathematical functions using polynomial expansions is implemented in a numeric processing system. A partial remainder operation is set forth for high accuracy reduction of polynomials whose arguments are greater than pi/4. The method may be practiced in a processor having a bus of approximately half the width of the precision of the desired result. Temporary registers are utilized for the storage of intermediate results. Full bus width accuracy is obtained through successive half bus width operations.
