  • Publication number: 20030162528
    Abstract: A vehicle communication path-tracing system (10) has a portable transmitter (12) and transceiver/controllers (14A-14N, 14T), located separately from the transmitter (12). A transmitter/controller (14T) is located at a target vehicle (16T) and at least one other transceiver/controller (e.g., 14A) is located at an intermediate location. An intermediate transceiver/controller receives a command signal intended for the target vehicle and transmits a retransmitted command signal intended for the target vehicle. The target transceiver/controller receives the retransmitted command signal and transmits an acknowledgement signal, intended for reception by the at least one intermediate transceiver/controller that transmitted the retransmitted command signal received at the target vehicle. The at least one intermediate transceiver/controller receives an acknowledgement signal and transmits a retransmitted acknowledgement signal.

  • Patent number: 6610633
    Abstract: A lanthanum aluminate (LaAlO3) substrate on which thin films of layered perovskite copper oxide superconductors are formed. Lanthanum aluminate, with a pseudo-cubic perovskite crystal structure, has a crystal structure and lattice constant that closely match the crystal structures and lattice constants of the layered perovskite superconductors. Therefore, it promotes epitaxial film growth of the superconductors, with the crystals being oriented in the proper direction for good superconductive electrical properties, such as a high critical current density. In addition, LaAlO3 has good high frequency properties, such as a low loss tangent and low dielectric constant at superconductive temperatures. Finally, lanthanum aluminate does not significantly interact with the superconductors. Lanthanum aluminate can also be used to form thin insulating films between the superconductor layers, which allows for the fabrication of a wide variety of superconductor circuit elements.

  • Patent number: 6611324
    Abstract: A method for determining the susceptibility of solar cell coverglass assemblies to degrade wherein the solar cell assembly contains coated or uncoated coverglass, the method comprises exposing the solar cell coverglass assembly with a pulsing laser having an energy per unit area per pulse which distinguishes by laser damage between coverglass assemblies that have an anomalously high propensity to darken under solar exposure and those that only have a normal, nominal propensity to darken; and, characterizing the propensity of the coverglass assemblies to darken. The process results in an improvement of the long-term power output of solar cells by maintaining optical transparency and reducing temperature increases arising from increased solar absorption in darkened coverglass assemblies.

  • Publication number: 20030150667
    Abstract: A steering system (10) for a vehicle (16) comprises a housing (20) having first and second end portions (32, 34) and an intermediate portion (50). A steering member (66) is supported for axial movement in the housing (20). A piston (100) fixed for movement with the steering member (66) has opposite end faces (104, 106). First and second springs (130, 132) engage the end faces (104, 106) of the piston (100) and bias the piston and thereby the steering member (66) in first and second axial directions toward a straight ahead position. Steering linkage (124, 126) connected with the piston member (100) transmits movement of the piston member (100) to steerable wheels (12, 14) of the vehicle.

  • Patent number: 6605167
    Abstract: An autoignition material includes a plurality of agglomerates. Each agglomerate comprises an oxidizer material particle. A plurality of metal fuel particles are disposed on the oxidizer material particle. The metal fuel particles are present in a weight ratio effective to substantially stoichiometrically balance the oxidizer material particle. The metal fuel particles exothermically react with the oxidizer material particle when the autoignition material is exposed to a temperature of about 80° C. to about 250° C. A thin binder film adheres the metal fuel particles to the oxidizer material particle and maintains the metal fuel particles in intimate contact with the oxidizer particle.

  • Publication number: 20030145675
    Abstract: An apparatus (10) includes first and second plates (44 and 84) extending parallel to each other and movable relative to each other. A locking mechanism (140) prevents movement between the first and second plates (44 and 84). The locking mechanism (140) has a first position applying a force to urge the first and second plates (44 and 84) toward each other to prevent movement between the first and second plates. The locking mechanism (140) has a second position to permit relative movement between the first and second plates (44 and 84). A surface treatment on one of the first and second plates (44 and 84) and between the first and second plates resists relative movement between the first and second plates when the locking mechanism (140) is in the first position. The surface treatment lubricates relative movement between the first and second plates (44 and 84) when the locking mechanism (140) is in the second position.

  • Publication number: 20030145650
    Abstract: A tire condition sensor unit (e.g., 18A) is for use within a tire condition communication system (10). The sensor unit (e.g., 18A) is for association with a tire (e.g., 14A) of a vehicle (12) and, via a method, communicates a tire condition to a vehicle-based unit (28). A sensor (58) senses the tire condition. Radio frequency transmit circuitry and an antenna (68 and 22) transmit a radio frequency signal (e.g., 24A) that indicates the sensed tire condition. In one aspect, a low frequency antenna and a signal detector (48 and 52) receive a low frequency initiation signal that causes transmission of the radio frequency signal indicative of the sensed tire condition. In another aspect, the radio frequency signal is also indicative of a fixed identification.
