Abstract: A method of anonymous targeted insertion of indicia into video broadcasts. Individual televisions or other video reception devices are associated with set-top boxes that monitor the usage and viewing habits of the television set or other video reception device. A viewer profile derived from data acquired from said monitoring is created wherein the viewer profile indicates certain characteristics about the viewer. This profile is transmitted to a centralized database, said centralized database being an intermediate link between the origin of the video broadcast and the end viewer. The purpose of the database is to link specific insertable indicia with matching specific viewer profiles. The insertable indicia are encoded directly into the broadcast video and re-broadcast to the end viewer where the set-top box decodes the broadcast video and performs insertion of the indicia. Thus, the system and method allow advertisers to target specific ads or indicia to specific viewing profiles.

Abstract: A method to precisely position an electronic component within a cutout on a printed circuit board before attachment to said board. A nest precisely positions and firmly holds the component in place. Inner walls of the nest match the component's dimensions while the outer walls are stepped and match the cutout dimensions. In the preferred embodiment, the nest is mounted on a top plate above the circuit board. The operator places and centers the component in the nest, by means of the nest's shape or leaf springs which hold the component centered. Components are positioned by wiggling the nest until the stepped sides engage the PCB. In an alternative embodiment, the operator turns an eccentric cam applying force to a spring, pushing the component towards one edge of the nest for alignment. Both embodiments, hold the component so the operator can fasten the component to the board with both hands.

Abstract: Reliable transmission of signals in a multi-channel system is achieved by transferring signal inputs from a defectively operating or inoperative transmitter to another transmitter which continues to transmit other channels. At least two transmitters are operated normally, each transmitting its own block of channels. A sensor detects when the output of one transmitter is improper or non-existent, and causes a change-over switch to operate. Operation of the switch adds the block of channels which had come from the one transmitter to the other (or one or more) of the transmitters, so that the remaining transmitter or transmitters now provide all the channels.

Abstract: The invention describes a door closer with an energy storage that includes a resisting spring (3), with a closer shaft (1) driven by the resisting spring (3) and with an hydraulic fluid damped damping device (12, 13), whereby the energy storage and the damping device (12, 13) act upon a common closer shaft (1), whereby the resisting spring (3) and the closer shaft (1) are not in contact with the fluid of the damping device (12, 13). In this way a particularly slim housing is possible.

Abstract: A sterilizable bracket (10) for supporting medical instruments (22) includes a resilient body (12) that surrounds and encapsulates a relatively rigid metal skeleton (14) which is attached to a plurality of studs (16) which secure the bracket (10) to a sterilizable tray (18). instruments (22) are received in indentations (24) in the resilient body (12). Each indentation (24) includes a plurality of ribs or fingers (28) which permit sterilizing steam to flow around the instruments (22). The resilient body (12) comprises a silicone material which encapsulates the skeleton backbone (14) which, in turn, gives the bracket (10) strength and flexibility. Threaded studs (16) having a slot (46) at one end and threads (50) at the other are employed to attach the bracket (10) to the sterilizable tray (18). The slot (46) in the head (44) of each of the studs (16) receives the metal skeleton backbone (14).

Abstract: The DC offset error of a quadrature modulated RF signal is corrected by introducing a specific trial offset correction value, D, into the DC offset correction circuits 3, 4 or 5 times, by measuring the carrier power resulting from each trial introduction, and by using the information to determine the DC offset correction components, Icor and Qcor. According to an ideal case first embodiment, specific offset D is employed in three different measurement combinations to determine the correction factors Icor and Qcor. According to an alternative embodiment, a fourth offset correction measurement, needed to estimate a single offset control scale factor, is used to account for an unknown power scale factor A. According to a second alternative embodiment, five offset correction measurements are used to account for separate offset control scale factors for the I and Q channels.

Abstract: A printed circuit board is aligned to its mounting plate by using cutouts already cut for electronic components. A top plate with a notched location block and two edge locators is placed on top of both the printed circuit board and the mounting plate so that the notched block straddles two cutouts on the board and the mounting plate. At the same time, the two edge locators are placed inside the two matching cutouts. An eccentric cam is used to move a pressure plate that slides on top of the top plate and pushes both the circuit board and the mounting plate with spring action. The cam is turned until the edge locators hit the edges of the cutouts, aligning the printed circuit board to the mounting plate.

Abstract: A self-inflatable mattress is formed from an open pore foam core and one or more layers of dual melt film. Initially, a layer of dual melt film is placed on top of the open pore foam block such that the side with the lower melting temperature contacts the foam core. A non-stick, heat transferable buffer layer is then placed on top of the film and heat and pressure are applied, preferably through a roller, causing the bottom surface of the film to stick to the top surface of the foam core. The edges of the top sheet are also adhesably attached to the sides of the core using a pair of heated side pressure rollers. Lastly, the cushion is inverted and a second, or bottom, sheet of dual melt film is placed on top of the foam core and attached to the bottom surface and the sides in a similar manner. Finally, a valve, which may be either oral, or one way, is attached to the side of the mattress.

Abstract: The invention relates to a method and device for measuring cerebral electrical activity in a patient. Cerebral electrical activity is measured in the form of electrical signals. Said signals are amplified and converted to signals which are then stored. The digitized signals and/or the stored digitized signals are processed as individual signals and as two channel signals for both cerebral hemispheres of the patient. A brain function index is thus determined to measure the normality of the patient's brain function.
