Patent number: 10236575Abstract: An antenna system comprises an antenna feed support and a driver. The antenna feed support is configured to mount a circularly polarized antenna feed to an antenna dish to extend outward along a longitudinal axis of the circularly polarized antenna feed with respect to a reflective surface of the antenna dish. The driver is configured to rotate the circularly polarized antenna feed to adjust alignment between the circularly polarized antenna feed and a remote antenna. The driver can rotate the circularly polarized antenna feed mechanically, electrically or both to adjust alignment between the circularly polarized antenna feed and a remote antenna to reduce cross-pol discrimination at the circularly polarized antenna feed.Type: GrantFiled: January 14, 2016Date of Patent: March 19, 2019Assignee: HUGHES NETWORK SYSTEMS, LLCInventors: Jack Lundstedt, Peter Hou, David Farrow, Ramesh Kollipara

Publication number: 20110097788Abstract: The invention relates to methods and devices for detecting the presence of a particle of interest (hereinafter an analyte particle) in a fluid. A detection device exemplary of the present invention filters a sample of the fluid to remove particles larger than the analyte particles. A reagent solution, containing reagent particles smaller than the analyte particles, is then added to the sample. The reagent particles will react with the analyte particles, if any are present, to form reagent-analyte complexes which are larger than the analyte particles. The sample is then filtered a second time to remove particles the same size as or smaller than the analyte particles. The sample is then tested for the presence of reagent-analyte complexes to detect the presence of the analyte particle in the fluid.Type: ApplicationFiled: October 29, 2010Publication date: April 28, 2011Inventor: David FARROW

Publication number: 20070130682Abstract: A load bearing grab bar to be used in public and household restrooms to aid elderly or handicapped people in lowering or raising themselves from a toilet or wheelchair. The grab bar is attached to the baseboard of the wall or an existing handrail, and has an adjustable support leg to provide better stability when weight is applied. The grab bar rotates from a vertical stored position to a horizontal in-use position to allow for better and safer mobility around home bathroom or public toilet stall.Type: ApplicationFiled: February 21, 2007Publication date: June 14, 2007Inventor: David Farrow

Patent number: 5972478Abstract: Label assemblies are produced which obscure confidential information that is part of each label assembly, while allowing ready exposure of the confidential information in a tamperproof manner. A web of label components having a face ply with a top surface, underlying pseudo adhesion layers, an underlying image ply, an underlying adhesive layer, and a bottom release paper carrier ply are acted upon to non-impact print a security pantograph and readable indicia on the web face ply, and with an impact element generate a confidential information image on the image ply, which image is not visible from the face ply. Labels are die cut out of the web and matrix material formed by die cutting is removed so that the web then includes a bottom release paper carrier ply with a plurality of spaced labels, each having a confidential information image. The labels may be applied to a mailer or other substrate.Type: GrantFiled: July 31, 1995Date of Patent: October 26, 1999Assignee: Moore Business Forms, Inc.Inventor: David Farrow

Patent number: 4781120Abstract: A toy monorail set is provided including a building for containing the parts to the set and selectively being a component part of the set. The monorail vehicle, building and monorail tracks are all made of sanded hardwood or other suitable smooth and hard material. The vehicle itself includes a cutout and a pair of extension members extending outward from the bottom of the cutout. The cutout has concave sides and the extension members have a flat surface and slanted sides from the back of the cutout to the flat surface so as to allow the vehicle to traverse a curved monorail track course. A smoothing additive, such as wax or paraffin is applied over the flat surface of the extension member and the top, or riding, surface of the monorail track to allow the vehicle to slide over the monorail track. The monorail tracks have semicircular ends with a circular recessed surface on opposite sides at each end.Type: GrantFiled: January 14, 1987Date of Patent: November 1, 1988Inventors: David A. Farrow, George M. Kinley, III, Michael A. Sandler
