摘要： Video, voice and data are integrated using existing telephone connections by using a video network server to receive and transmit video signals to and from clients using telephone wires. Client frequency division multiplexing couplers, each associated with one of the clients, receive video and telephone signals from the client and frequency multiplex them onto the telephone wires for transmission. They also receive video signals from the server and frequency demultiplex them for transmission to the client. A video frequency division multiplexing coupler connected between the video network server and each of the client frequency division multiplexing couplers receive the video and telephone signals from the clients and transmit only the video signals to the video network server. A telephone frequency division multiplexing coupler connected between a telephone network switch and each of the client frequency division multiplexing couplers receive the video and telephone signals from the clients and transmit only the telephone signals to the telephone network switch.

摘要： An electromagnetic interference (EMI) shield that increases the airflow through the EMI shield while preventing line-of-sight openings through the EMI shield. Two plates are coupled together. Each of the respective plates has a raised component with an aperture therethrough to provide a path through the plate. The raised component is preferably scoop-shaped with the aperture at one end and an opposite end tapering into the respective plate. At least a portion of one of the raised components overlaps at least a portion of the other of the raised components when the plates are coupled together to form a path through the plates, while the plates are coupled together. Line-of-sight openings through the plates, to an electronic device protected by the EMI shield, are at least partially prevented by the raised components.

摘要： An optical adapter for an imaging system correcting images of spherical or near spherical bodies such as the earth during satellite image collection. An imaging system includes an image collector that collects a two-dimensional image of the body from a distance above the body such as from a satellite in geostationary orbit. The collected image is disk shaped and includes distortion due to earth curvature, primarily in the form of a loss of resolution due to the foreshortening of earth features in a radial direction extending outward from the center of the image disk. The optical adapter receives the collected image, transforms the collected image to correct the distortion, and outputs a corrected image with essentially uniform spatial resolution across the areas for which the correction is applied. An image sensor such as charge-coupled device array senses the corrected image and creates a digital representation of the corrected image.

摘要： An airbag cushion assembly including a horn switch unit secured to an airbag cushion with a cushion strap, with the cushion strap and horn switch unit cooperating to retain the airbag cushion in a deflated, folded position prior to mounting the airbag cushion assembly within an airbag module and prior to inflation of the airbag cushion. The horn switch unit defines a first elongated slot, a second elongated slot and a weakened portion rupturable upon a force created by inflation of the airbag cushion to break the horn switch unit between a first and a second elongated slots defined by the horn switch unit. The horn switch unit is positioned on the folded airbag cushion opposite the collar, with a first elongated tether of the cushion strap extending through the first slot of the horn switch unit to a distal end secured to the collar of the airbag cushion, and a second elongated tether extending through the second slot of the horn switch unit to a distal end secured to the collar of the airbag cushion.
