Patent number: 8068062Abstract: A low power, lightweight, collapsible and rugged antenna positioner for use in communicating with geostationary, geosynchronous and low earth orbit satellite. By collapsing, invention may be easily carried or shipped in a compact container. May be used in remote locations with simple or automated setup and orientation. Azimuth is adjusted by rotating an antenna in relation to a positioner base and elevation is adjusted by rotating an elevation motor coupled with the antenna. Manual orientation of antenna for linear polarized satellites yields lower weight and power usage. Updates ephemeris or TLE data via satellite. Algorithms used for search including Clarke Belt fallback, transponder/beacon searching switch, azimuth priority searching and tracking including uneven re-peak scheduling yield lower power usage. Orientation aid via user interface allows for smaller azimuth motor, simplifies wiring and lowers weight. Tilt compensation, bump detection and failure contingency provide robustness.Type: GrantFiled: January 7, 2011Date of Patent: November 29, 2011Assignees: GBS Positioner, LLC., AntennaSys, Inc.Inventors: Spencer Webb, David Martin

Patent number: 8024031Abstract: Device for classifying tachyarrhythmia that obtains pre-defined values, monitors atrial intervals and compares lengths of each interval with pre-defined value IL, stores length of atrial interval if length is shorter than IL, in case X of most recent Y number of atrial intervals have length shorter than IL, evaluates most recent <=N atrial intervals with length <IL and performs test for stored lengths via criteria, classifies atrial tachyarrhythmia as stable if all tested lengths pass >=1 criteria, and controls a cardiac device depending on the classification. Atrial intervals are first evaluated by using the “X-out-of-Y” criterion and subsequently checked for stability after an atrial tachyarrhythmia is detected using “X-out-of-Y” criterion. For stability check, only intervals found shorter than the interval limit are used. Check is based on interval-to-interval comparison rather than as generally practiced, comparisons of individual intervals with the minimum or average of all intervals.Type: GrantFiled: October 20, 2008Date of Patent: September 20, 2011Assignee: Biotronik CRM Patent AGInventors: Indra B.

Patent number: 7988076Abstract: A non-clogging non-pressure compensated drip emitter that utilizes one or more filters or one or more inwardly offset filters that have an inlet that projects inwardly toward a centerline of the hollow cylindrical emitter body and a labyrinth having only turbulent transfer zones after water enters the labyrinth, wherein the labyrinth couples the filter(s) or inwardly offset filter(s) to the pool. Prevents clogging by eliminating dead transfer zones where sediment can accumulate where no turbulence exists. Also prevents clogging when the filter is positioned downward as the inwardly offset filter rises above any sediment when the emitter is positioned in the field in this downward orientation. Also prevents clogging flat filter configurations that have filters offset radially, i.e., redundant filters per emitter.Type: GrantFiled: October 20, 2008Date of Patent: August 2, 2011Assignee: D.R.T.S.
