Abstract: A computer based method of biometric analysis which compares a first vector from a first biometric sample with a second vector from a second biometric sample. The vectors have at least one biometric feature. A method which compares two biometric samples. The samples form at least one cluster of at least one vector based on feature similarities between the samples. An apparatus incorporating a means for performing the method taught herein. A computer-readable medium and a propagated computer data signal transmitted via a propagation medium, with instructions which when executed by a processor, carry out the method of the present invention. A method of handwriting analysis which calculates a first metric from a first vector having at least one feature from a sample, calculates a second metric from a second vector having at least one feature from a second sample, and calculates the distance in two-dimensional feature space between metrics.

Abstract: A raster video display system utilizes memory capacity more efficiently than conventional raster display systems and is independent of the specific resolution of the screen which is utilized in the system. The raster display system comprises a VRAM with split transfer capability and a unique address generator which can determine when pixels from a particular row of the screen display start on one row of the VRAM and extend over to the next row of the VRAM.

Abstract: A pixel arrangement scheme for a high resolution graphics display system, using video RAMs. Pixels are time multiplexed instead of using a temporary memory in a conventional system. Memory arrangement to implement this scheme is made to obtain higher speed and lower cost, consistent with the increased capacity of VRAMs.
