Abstract:
An ultrasonic pulse is transmitted through a crimping tool that compresses a ferule circumscribing a braided multiple strand wire, thereby forming a crimp therebetween. A first received pulse is received from the first transmitted pulse after passage through the crimp. Data is collected from a first transmit window divided into a series of user-defined time periods that include the first transmitted pulse, a delay period following the first transmitted pulse, the first received pulse, and a lag period that extends from the end of the first received pulse to a second transmitted pulse that initiates a second transmit window. The lag period includes a second received pulse generated by delayed signals received from the first transmitted pulse and dead periods that occur before and after the second received pulse, the dead periods substantially lacking signal information from the first transmitted pulse.
Abstract:
Sealing members for vehicle radiator assemblies and vehicle radiator assemblies comprising sealing members are disclosed. In one embodiment, a sealing member for a radiator assembly includes a central panel, a mounting connector, and a flexible skirt element. The mounting connector may be formed in an upper edge of the central panel and extend across a width of the central panel. The mounting connector and the central panel are formed from a first polymeric material. The flexible skirt element may be formed in a lower edge of the central panel and extend across the width of the central panel. The flexible skirt element may be formed from a second polymeric material that is elastically deformable and recoverable. The first polymeric material may be relatively harder than the second polymeric material. The sealing member may be coupled to a radiator assembly installed in an engine compartment of a vehicle.
Abstract:
A triacetone triperoxide cloud associated with a triacetone triperoxide explosive attached to a hard target is remotely detected by operating differential-absorption lidar lasers to transmit a laser beam toward the hard target at differing wavelengths. A backscattered laser beam reflected from the lidar target (hard target, person, aerosols, clouds, buildings) is detected because a cloud of triacetone triperoxide in front of the lidar target and between the lidar target and the differential-absorption lidar system produces a differential-absorption signal having characteristics that identify the triacetone triperoxide. In a second embodiment, a triacetone triperoxide cloud that is absorbing optical radiation from its ambient environment and which is attached to a hard target is detected from a location remote from the triacetone triperoxide explosive by detecting an optical radiation absorption signature characterized by triacetone triperoxide absorption lines.
Abstract:
A soft single-ply tissue sheet is produced by making a textured, high bulk, through dried tissue sheet and calendering the sheet with a high level of compression energy to substantially reduce the bulk and impart improved properties to the sheet.
Abstract:
A device for inserting a subcutaneous infusion device into skin of a patient. The device can include a housing, a needle hub including a needle, a sleeve, and a spring engaging the needle hub. The device can also include a cap coupled to the housing, and a retention member configured to maintain the device in a ship state prior to decoupling of the cap from the housing. In one example, the retention member can include a boss coupled to the cap and configured to engage the infusion device to maintain the infusion device in the ship state prior to decoupling of the cap from the housing. In another example, the retention member can include a tab formed by the sleeve, the tab engaging a bead on an internal surface of the cap when the sleeve moves relative to the housing while the device is in the ship state.
Abstract:
The device lubricates a sail edge channel, such as a luff channel in a luff channel extrusion fitted to a forestay of a sloop. The device comprises a slide arranged for insertion into and for sliding along the channel and a reservoir for containing a lubricant. A web connects the slide to the reservoir and extends from the slide out of the sail edge channel so that the slide can slide in the channel with the reservoir outside the sail edge channel. A passageway extends from the reservoir and through the web to at least two outlets from the slide arranged at different angular positions around the slide. The lubricant can be expelled from the reservoir into the passageway so that the lubricant is expelled from the outlets into the sail edge channel.
Abstract:
A method of reducing static power consumption in a low power electronic device. The electronic device including one or more power islands, each power island including: a local storage capacitor coupling a local power grid to a local ground grid; and a functional circuit connected between the local power grid and the local ground grid; a global storage capacitor coupling a global power grid to a global ground grid, each local ground grid connected to the global ground grid; one or more switches, each switch selectively connecting the global power grid to a single and different corresponding local power grid; and a power dispatch unit adapted to open and close the one or more switches.
Abstract:
A system, method and program product for retaining a logic state of a processor pipeline architecture are disclosed. A comparator is positioned between two stages of the processor pipeline architecture. A storage capacitor is coupled between a storage node of the comparator and a ground to store an output of the early one of the two stages. A reference logic is provided, which has the same value as the output of the early stage. A logic storing and dividing device is coupled between the reference logic and a reference node of the comparator to generate a logic at the reference node, which is a fraction of the reference logic, and to retain a logic state of the information stored on the storage capacitor. Further mechanisms are provided to determine validity of data stored in the logic storing and dividing device.

Abstract:
A microwave circuit comprises a printed circuit board (PCB) on which is fabricated a circuit including passive components such as filters (40) formed by printed conductive patterns. In order to enhance the performance of the circuit, selected components such as filters are made with a greater precision on substrate material (41), such as alumina, having a higher dielectric constant than that of the printed circuit board material. The finished component is mounted on the printed circuit board and the conductive pattern is connected by wire bonds (48, 50) to microstrip tracks (51) of the printed circuit board.
