Title: Adaptive precoding system and method to compensate for changes in a communications channel
Inventor: LANGBERG EHUD
IPC: H04L25/49
Filed: 1998-04-28
Granted: 2000-07-21
Abstract: An adaptive precoding system is implemented within a data communications system in order to precode data to track chagnes in a communicaitons channel.  The adaptive precoding system initializes a set of precoder values within a precoder filter of a transmitter during an initialization phase.  The precoder filter is used to create a precoding signal that is combined with a transmission data signal in order to compensate for distortions on a communications channel.  During a communications phase, a decision feedback equalizer generates equalizer coefficients that correspond to changes in communications channel.  The equalizer coefficients are periodically transmitted to a converter within the transmitter over a secondary channel.  The converter determines a new set of precoder values that compensate for the changes in communications channel and slowly updates the values in the precoder filter until they match the new set of precoder values.  While the precoder values are being updated, the decision feedback equalizer updates the equalizer coefficient values to reflect the improvements realized by updating the precoder values.

Granted: 1999-12-11
Abstract: A method and apparatus for detecting surface defects and artifacts on a transmissive image (300) in an optical image scanner and correcting the resulting scanned image. In one scan, the image is scanned normally. Surface defects and artifacts such as dust, scratches and finger prints are detected by providing a separate scan using infrared light (304) or by measuring light (white or infrared) that is scattered or diffracted by the defects and artifacts. Separate optical paths for illumination (406, 410) may be used, or separate optical paths for intensity measurement (510) may be used. Image processing may then be used to correct areas in the normal scan corresponding to defects identified in the separate scan. A method of detecting surface artifacts on a transmissive image medium (300), the method comprising the following steps: (a) measuring light intensity along a first optical path (402) that passes through a point on the medium; (b) providing illumination (404, 408, 704) through the medium, at the point, along a second optical path (406, 410), the second optical path being different than the first optical path, so that the measured light intensity of step (a) results from light along the second optical path being redirected onto the first optical path at the point on the medium; (c) comparing the intensity measured in step (a) to a predetermined threshold (816, 822); and (d) identifying the point on the medium as a surface artifact on the medium as a result of the comparison of step (c).

Title: Composite magnetic ceramic toroids
Inventor: GORDON STUART
IPC: H01F17/06
Filed: 1999-10-29
Granted: 2001-11-21
Abstract: Disclosed is a method of producing gapped ferrite toroids without the necessity of machining. This allows for the highly efficient production of tightly controlled energy storage magnetic components and stable inductors. Composite toroids of the invention have a wide range of applications, and could be used as substitutes for more costly and less operationally efficient magnetic components. This invention provides a method of producing composite toroids that include a nonmagnetic gap, by utilizing a layer-forming method, such as tape casting, and subsequently co-firing a monolithic composite magnetic and non-magnetic ceramic structure produced by stacking the layers. The toroids are punched from the stacked layers prior to final firing. This novel method provides a means for producing very well controlled gapped structures.
