Title: Memory controller with adaptive processor interface port
Inventor: SEEMAN THOMAS R
IPC: G06F15/78
Filed: 2003-10-24
Abstract: A computer system architecture and memory controller (502) for close-coupling within a hybrid computing system using an adaptive processor interface port ("APIP") (524) added to, or in conjunction with, the memory and I/O controller chip of the core logic. Memory accesses to and from this port, as well as the main microprocessor bus, are then arbitrated by the memory control circuitry (514) forming a portion of the controller chip. In this fashion, both the microprocessors and the adaptive processors of the hybrid computing system exhibit equal memory bandwidth and latency. In addition, because it is a separate electrical port from the microprocessor bus, the APIP is not required to comply with, and participate in, all FSB protocol (512). This results in reduced protocol overhead which results higher yielded payload on the interface.

Title: Strokes localization by m-array decoding and fast image matching
Inventor: DANG YINGNONG
IPC: G06F3/033
Filed: 2005-01-14
Abstract: Systems and methods that determine a path of a pen tip as the pen tip is moved across a document are described. The document is watermarked with a maze pattern from which encoded position information is determined. A sequence of images is captured by a camera that is located in a pen. The path of the pen tip is determined by decoding the associated maze pattern and by matching the captured images with document images. If the position coordinates of any frame that is associated with a stroke cannot be determined from m-array decoding, the frames are transformed and then matched with an area of a document image. Once the position coordinates of at least one frame is determined, the position coordinates of other frames are determined by matching the frames in a neighboring area.

Abstract: An automatic chemistry analyzer is provided having a high throughput and a high reliability. The analyzer uses nephelometric and turbinmetric analyzers (68) to analyze a wide variety of parameters within liquid samples typically generated in, for example, a large medical testing laboratory. The machine employs a unique probe (84) and stirring rod (86) assembly (80) mounted at a slight angle (a) with one another using rack and pinion assemblies (106) so that the lower end of the probe (84) and the lower end of the stirring rod (86) are in very close proximity to one another. This feature allows the machine to be used in unusually small reaction cuvettes (54). The analysis machine also includes an onboard control sample (78) so that the machine can be programmed to periodically calibrate its analyzing equipment during the course of normal operation. The machine also includes a sample station carousel (24) having retainer clips (39) for retaining a sample container rack (30) which is constructed to retain a bar-coded card (37) containing information regarding reagents used in the machine. A bar code reader (47) located proximate to the sample carousel reads the bar-coded reagent information into the controller.
