Abstract: A system and method are provided for automatically tracking the movements of an acoustic source relative to two or more microphones possibly mounted in a portable device. The microphones are mounted so that they may be separated from an acoustic source that can be more than three inches from the portable device. By automatically tracking the location of a portable device, a directional response of unidirectional microphones in a far field setting can be steered so that the radial axis of the directional response aligns with the path in which the acoustic wave travels from the source to the microphones. By tracking the source and steering the directional response of the microphones, the system can thereby properly delay and filter electrical signals added to the outputs from corresponding microphones to maximize the signal-to-noise ratio of the ensuing signal.

Abstract: A stocking for use in positioning a pulsatile bladder about a portion of a user's body is described. The stocking is desirably circularly knit to have an inner sleeve, and an outer sleeve extending concentrically over the inner sleeve. The inner sleeve desirably is knit to provide a graduated degree of compression along the underlying portion of a person's body when the stocking is positioned on a wearer's limb. The outer sleeve is preferably relatively less elastic than the inner sleeve, so as to prevent a bladder positioned within the stocking from pressing uncomfortably into a wearer's flesh. The outer sleeve also desirably includes first and second spaced-apart openings, one for bladder insertion and the other for allowing the exit of tubing typically associated with pulsatile bladders. The stocking is preferably integrally knit on a circular knitting machine such that it comes off of the machine in finished form.

Abstract: A method and apparatus for determining and selecting configuration options and settings of circuit boards used in a computer system is disclosed. The options and settings are placed in a file according to a given format, at which time the system determines if non-conflicting use of the common system resources is possible. If so, these option and setting parameters are used to configure the circuit boards.

Abstract: A nozzle attachment (10) for cleaning residual material from a mixhead pour nozzle (16) having a cylindrical body (17) terminating in an end face with an axial bore (20) receiving a plunger (23) including, a sleeve (30) positioned outwardly of the cylindrical body forming a plenum chamber (52), ports (40, 41) in the sleeve communicating the plenum chamber with a source of pressurized fluid (70), and a cap (60) positioned circumferentially of the end face of the pour nozzle and providing an annular substantially radially inwardly directed orifice (65) communicating with the plenum chamber for directing pressurized fluid inwardly across the end face of the pour nozzle to remove residual material therefrom. A pressurized air supply system (70) provides air at different pressures to the nozzle attachment at selected times during the operating cycle of the mixhead pour nozzle.

Abstract: A computer program permits a user to simulate configuring add-in boards for a computer system. A board may be "pulled" from an inventory list for inspection, and may be "inserted" into any legal slot in the computer system. The program can automatically generate any permissible configurations for the board, i.e., configuration of the board's address resource allocations that avoid conflicts with the address resource allocations of other, already-installed boards. The user may select from among permissible configurations; for a selected configuration, the user may display to screen or printer a drawing of the switch- and jumper settings on the board that are needed to implement the selected configuration.
