Patent number: 7461874Abstract: A bumper system includes a rollformed tubular beam with bracket mounts welded to a rear surface for mounting to vehicle frame rails. The illustrated beam has a continuous tubular cross section for its entire length, and includes a center section, corner-forming end sections, and mounting sections connecting ends of the center section to the end sections. The center, end and mounting sections can be linear or similarly curved or differently curved. The center, end and mounting sections can be similarly or differently locally annealed as part of being tuned to specific impact loading criteria, including annealing all or part of cross-sectional areas. The annealing can be done in-line with a rollforming process, such as to assist with forming tight radii in the beam for meeting packaging/space-related requirements, or can be part of a secondary process for advantageously affecting impact strengths in selected localized areas.Type: GrantFiled: August 29, 2007Date of Patent: December 9, 2008Assignee: Shape CorporationInventors: Melvin Guiles, Rainer B.

Patent number: 6971690Abstract: A bumper system includes a “W” or “C” shaped beam having a back wall and mounts along the back wall adapted for attaching the beam to rails of a vehicle frame. An energy absorber engages a face of the beam and has rearwardly-extending energy-absorbing sections that extend through the face into contact with the back wall at each of the mounts for improved energy absorption. The horizontal walls of the beam have front and rear sections that align, but also have a U-shaped intermediate section that weakens the walls for promoting a more uniform and predictable collapse. A one-piece brace includes diagonal straps that hold free ends of top and bottom walls together to prevent premature spreading apart upon impact. The energy absorber includes energy-absorbing sections that extend past the straps to detentingly engage the intermediate sections of the beam.Type: GrantFiled: June 9, 2004Date of Patent: December 6, 2005Assignee: NetShape International, LLCInventors: Darin Evans, Thomas J.

Patent number: 6748218Abstract: Wireless communication methods and systems using multiple sectored cells. In one example, each cell of a cellular coverage area is divided into a number of sectors. A number of different half duplex or full duplex channels are used in each cell to communicate between a base station and a number of subscriber stations located in the cell. At least some of the channels may be reused in other cells of the coverage area. Additionally, some channels may be reused both amongst sectors of a given cell and in other cells of the coverage area. The sectored cells are arranged with respect to one other such that interference amongst similarly oriented sectors of different cells using one or more same channels is reduced.Type: GrantFiled: April 10, 2000Date of Patent: June 8, 2004Assignee: Remec, Inc.Inventors: Thomas J.

Publication number: 20030198339Abstract: A compact sound processing system and method for use with a plurality of sound radiators. A microcontroller accepts a plurality of user-selected speaker equalization and space equalization settings and receives a paging control signal from a telephone interface. An analog mixer combines music signal inputs and a paging signal. A digital signal processor generates and filters masking noise, and processes the masking noise and combined music and paging signals based on user-selectable settings for distribution to the sound radiators. An audio amplifier modulates and amplifies the output signal from the digital signal processor, and delivers the output signal to the sound radiators via a transformer in defined zones. The sound radiators can be flat panel sound radiators or conventional type speakers. A masking filter used with the masking noise generator can be programmed to shape the virtual random noise generated by decreasing the noise at a constant rate over the frequency range of human speech.Type: ApplicationFiled: April 19, 2002Publication date: October 23, 2003Inventors: Kenneth P.

Publication number: 20020151309Abstract: Two or more sectors of a coverage area of a wireless communication system may be linked together to form a wide area network. Each sector is associated with at least one radiation pattern carrying information, and the sectors forming the wide area network share at least some of the same information. One base station modem used to encode and decode information may be coupled to two or more radio transceivers, wherein each transceiver is associated with a different sector. In this manner, two or more differently geographically disposed sectors essentially function as one wide area network, in that the multiple sectors are served by one base station modem. The number of sectors that are selected to be serviced by a particular base station modem may be based at least in part on one or more of a capacity demand and a topological distribution of subscriber stations in at least a portion of the coverage area.Type: ApplicationFiled: June 8, 2001Publication date: October 17, 2002Inventors: Thomas J.
