Title: Expanding dental implant and method of use
Inventor: HANOSH FREDERICK N
IPC: A61C8/00
Filed: 1995-05-10
Abstract: The technical field of the invention generally concerns an expandable dental implant for receiving and supporting a dental prosthesis. The expandable dental implant, securable within a bore formed into bone of a patient's jaw, includes an elongated, hollow, tubular barrel having both an attachment end and an insertion end. The barrel has both a threaded interior surface for screwing the implant into the bore, and a threaded exterior surface for receiving a threaded expander screw. The barrel is pierced about its insertion end by a plurality of radial slits spaced circumferentially around the barrel. The interior surface of the barrel at the insertion end is formed with a smaller diameter than the diameter of the interior surface of the barrel at the attachment end. The expander screw and the interior surface of the barrel are shaped so advancement of the expander screw along the barrel toward the insertion end causes an end surface of the expander screw to collide with the interior surface of the barrel, and to expand the insertion end outward into the surrounding bone.

Title: Adaptive filtering of matched-filter data
Inventor: WARREN RONALD W
IPC: G01S13/524
Filed: 1997-01-20
Abstract: An adaptive processor (50) which uses the successive range and Doppler outputs of a conventional matched-filter (58)  to improve the signal-to-noise ratio for non white noise/clutter.  The adaptive processor minimizes the output for a given range and Doppler cell with the constraint that the response to signals returning with specified range and Doppler offsets, with respect to the center of the range-Doppler cell,  each have specified values.   Weights are derived (64) which can be applied to range-Doppler outputs in the neighborhood of the range-Doppler cell to minimize its output subject to the constraints.  The weights depend on an estimate of the cross-covariance matrix (60) of the various outputs of the range-Doppler cells that are to be weighted.  The constraint parameters are specified in terms of the ambiguity function of the transmitted waveform. Synthetically  generated  covariance  matrices  (60')  or combinations of measured and synthetic matrices can also be used to produce desired modifications to the resulting range-Doppler response of the adapted process.

Title: Method for testing for gastroesophageal reflux disease
Inventor: ORR WILLIAM C
IPC: A61B5/00
Filed: 1997-08-21
Abstract: An easy, safe and inexpensive procedure for testing the presence of esophageal acid sensitivity in a patient involves having the patient swallow a controlled quantity of a weak acid solution and a similar-tasting controlled quantity of a neutral solution and recording the reactions or symptoms experienced by the patient during the drinking of each solution.  The acid solution only should affect the sensitivity of the esophageal lining in patients with esophageal acid sensitivity, provoking heartburn and other related symptoms to include non-cardiac chest pain, but should not have any significant effect on patients without esophageal acid sensitivity.  The neutral solution may be altered to stimulate the taste of the acid solution and reduce the effect the taste of the solutions may have on the test results.

Title: Multi-rate positioner system having an improved profiling filter
Inventor: PAILTHORP ROBERT M
IPC: H05K3/00
Filed: 1996-03-19
Abstract: A multi-rate positioner system (50) receives unpanelized positioning commands from a database storage subsystem (64), profiles the commands (72) into a half-sine positioning signal, and further processes the signal into a low-frequency positioning signal (LFP) and a high-frequency positioning signal (HFP) for actuating respective slow (56, 58) and fast (54) positioners to target locations on a workpiece (62). The slow and fast positioners move without necessarily stopping in response to a stream of positioning command data while coordinating their individually moving positions to produce temporarily stationary tool positions (140) over target locations defined by the database. The multi-rate positioning system reduces the fast positioner movement range requirement while providing significantly increased tool processing throughput.
