Patent Number Title Of Patent Date Issued
6636048 Method for diagnosing performance problems in cabling October 21, 2003
The present invention provides an apparatus for using time domain analysis of NEXT, Return Loss and the like, in conjunction with the application of time or distance referenced limits to verify and determine compliance of the performance requirements of connections in a typical link. Tim
6522152 Method and apparatus for adaptive cancellation of responses in cabling February 18, 2003
An Adaptive Vector Cancellation method which uses time domain data for an instrument connection to estimate magnitude, phase, and time position of a signal response such as NEXT or Return Loss associated with the connection. Based on the estimate of the amplitude and time of the conn
6433558 Method for diagnosing performance problems in cabling August 13, 2002
The present invention provides methods for using time domain analysis of NEXT, Return Loss and the like, in conjunction with the application of time or distance referenced limits to verify and determine compliance of the performance requirements of connections in a typical link. Time dom
5539321 Apparatus for measuring the crosstalk in a cable July 23, 1996
An instrument to measure crosstalk between conductor pairs is configured to transmit a signal at one pair and receive the signal at another pair. The spureous or parasitic crosstalk at the connectors is supressed using a vectorial substraction from the received signal.
5502391 Apparatus for measuring the crosstalk in a cable March 26, 1996
Apparatus to measure the crosstalk between pairs of conductors in a cable. The measurements are affected by the crosstalk inherent to the connectors that are part of the apparatus. The improvement consists of adding a compensating signal which equals that from the connector crosstalk in
5218174 Low power cordless magnetic field digitizer with differential grid sensing and synchronous posit June 8, 1993
A digitizing system includes a tablet and a cordless pointing device including a plurality of data grid conductors in the tablet and a plurality of clock grid conductors in the tablet, all receiving a magnetic field signal transmitted by the pointing device. A data channel circuit in
4859814 Noise cancellation in digitizing system and method August 22, 1989
A digitizing system includes a differential noise reduction technique wherein spaced parallel grid conductors in a tablet are differentially sensed in order to cancel out locally induced noise signals. Grid conductors also are sensed in a single ended fashion to initially locate a gr
4710767 Method and apparatus for displaying multiple images in overlapping windows December 1, 1987
A circuit is provided which receives pixel data and pixel addresses from a graphics processor and effectuates rapid clipping of image information lying outside of a corresponding window, and also provides a template memory for storing information corresponding to all areas of that window
