A receiving and filtering circuit includes an antenna, a demodulator circuit coupled to the antenna, and a digital median filter that removes high frequency content of a demodulated digital information signal to produce a filtered digital information signal corresponding to an analog data signal tra ...

Steven A Gabriel, Kent E Griffin: Method and system for texture mapping images with anisotropic filtering. Microsoft Corporation, Klarquist Sparkman Campbell Leigh & Whinston, December 21, 1999: US06005582 (212 worldwide citation)

A method for texture mapping an image includes passing an interpolating filter along a line of anisotropy in a texture map and computing a weighted sum of the outputs of the interpolating filter to compute pixel intensity values. The weighting of these output values can be computed using a one dimen ...

A compact, lightweight wrist-worn cardiac data and event monitor having dry skin electrodes integral with the monitor's housing. Preferably, the skin electrodes are made of titanium nitride-plated stainless steel and form inner, wrist-contacting, and outer, other hand's palm-contactable regions of t ...

John A Hauck, Arthur L Olive: Rate adaptive cardiac rhythm management device control algorithm using trans-thoracic ventilation. Cardiac Pacemakers, Haugen and Nikolai, June 7, 1994: US05318597 (179 worldwide citation)

A rate adaptive cardiac rhythm management device in which the pacing rate is adjusted in accordance with changes in the patient's minute ventilation. An adaptive four-pole elliptic digital filter, preferably implemented in software, functions to attenuate any signal components due to cardiac activit ...

Armando Cova: Predistortion in a linear transmitter using orthogonal kernels. Glenayre Electronics, Christensen O Connor Johnson Kindness PLLC, October 31, 2000: US06141390 (170 worldwide citation)

A system for linearly transmitting an amplified output signal using predistortion is disclosed. The system uses a straight inverse modeling scheme with orthogonal predictor variables to more easily and accurately determine the inverse of the distortion caused by a power amplifier of a RF transmitter ...

Robert Stephen Potratz, Michael W Nootbaar: Pulse oximeter with sigma-delta converter. Nellcor Puritan Bennett, Hovey Williams Timmons & Collins, July 13, 1999: US05921921 (162 worldwide citation)

A preferred oximeter detects the transillumination by red and infrared light of a portion of an in vivo subject and produces analog signals representative thereof on two channels. Sigma-delta modulators sample the analog signals on each channel. A digital filter processor digitally filters the sampl ...

Paul C Hershey, John G Waclawsky: System and method for a workstation monitoring and control of multiple networks having different protocols. International Business Machines Corporation, John D Flynn, John E Hoel, October 22, 1996: US05568471 (153 worldwide citation)

A workstation manages and controls a plurality of communication networks using different protocols coupled to a common bus. A programmable digital filter connected between the workstation and the networks examines frame information using real time calculation for identifying protocols in the frames. ...
