Abstract: A telescoping crossbar assembly for a wheelchair comprises an inner tube that is slidable within an outer tube. The head portion of a pass-through fastener bears on the inner tube through a sufficiently large head-side aperture so as to slightly deform the inner tube and to hold the two tubes by friction in mutual engagement.

Abstract: A modular wheelchair assembly is adapted to be reconfigured between a fixed angle of tilt, a dynamically adjustable tilt-in-space configuration with the tilt axis being near the user's knees and a dynamically adjustable tilt-in-space configuration with the tilt axis being near the user's center of gravity. The reconfiguration is achieved by modifying a limited number of selectively removable components of the support assembly or the pivot assembly of the wheelchair.

Abstract: A controllable and/or configurable device that communicates wirelessly with a station may be used to test the station. For example, the device may be configured to communicate in multiple different wireless communication modes. As another example, the device may be controlled to engage in wireless communications that do not comply with the communication standard, e.g., IEEE standard 802.11. As a further example, the device may be controlled to reduce the strength of the wireless signal that is transmitted. The station's response to the wireless communication may be evaluated.

Abstract: The invention is a data transmission medium and a method of data transmission. A data transmission system in accordance with the invention includes a plurality of modems; a transmission medium coupled to each of the modems with data transmissions between the modems being transmitted by the transmission medium with a data transmission protocol; a plurality of processors which use a common processor data protocol, each processor being coupled to one of the modems; a plurality of devices, each device receiving and/or transmitting data transmissions with a device data protocol and being coupled to a processor; and a plurality of digital devices, coupled to the transmission medium, which perform at least one of transmitting digital data to the transmission medium for transmission by the transmission medium to another digital device and receiving digital data from another digital device transmitted by the transmission medium.

Abstract: A jungle fighter aircraft conversion kit comprised of a gattling gun works (1) that is mounted at the nose cone (3) under portion of an aircraft (2), avionics grayboxes (8), vibration trays (5), a hood (9) for enclosure and a machine gun (10). The gattling gun works (1) is designed for repeat fire power in intermittent operations while the air vents (4) in the gattling machine gun works (1) are designed for cooling the weapon. The grayboxes (8) are located within the gattling works weapon (1) and are designed for control within the cockpit (7) of the aircraft. Both the weapon and the grayboxes (8) have vibration trays (5) mounted at each equipment base. The machine gun (10) is preferably compact and lightweight and similar in design to those used by United States secret service agents.

Abstract: The invention relates to an in vitro cell based expression system for overexpressing heterologous pump proteins associated with drug resistance into the membrane of the host cell for drug screening applications.

Abstract: A method of handling a compound storage vessel (4) disposed in a cavity in a rack, the cavity having an upper and lower opening. The method includes introducing a lifting pin (15) into the cavity through the lower opening to urge the compound storage vessel upwards within the cavity. A lifting head (16) may be placed above the rack for receiving compound storage vessels.
