  • Patent number: 7281889
    Abstract: A flexible cargo bed tie-down system allows the user to easily change, adjust, customize, and adapt his or her vehicle to specific needs at any given moment, and interfaces with the rest of the vehicle in an optimum manner from a functional, structural, and aesthetic standpoint. One embodiment of the invention provides a vehicle having a side wall construction enclosing a cargo bed at a side of the cargo bed. The side wall construction includes an outer portion which runs generally vertically at an outer portion of the vehicle, and a top portion which runs generally horizontally from the outer portion toward a longitudinal center of the vehicle. A tie-down rail is mounted adjacent to the top portion such that a part of the top portion overhangs at least a portion of the tie-down rail. The tie-down rail is configured to accept a tie-down fitting and includes a slotted opening generally aligned with an interior edge of the top portion.

  • Patent number: 7248058
    Abstract: A testing device for determines values of various electrical variables associated with a device within a process system. The testing device provides bi-directional electrical communication with a device to be monitored and automatically provides a connection configuration between a processing unit and a set of input/output ports. The connection configuration governs a bi-directional flow of electrical signals between the processing unit and the device to be monitored. The processing unit outputs a test signal and a configuration control signal to the input/output port control circuitry. The input/output port control circuitry, in response to received test and configuration control signals, automatically provides a connection configuration to direct the test signal to the device to be monitored and to direct a return signal, the return signal being generated by the monitored device in response to the test signal, to the processing unit.

  • Publication number: 20070117347
    Abstract: The invention includes methods of forming isolation regions. An opening can be formed to extend into a semiconductor material, and an upper periphery of the opening can be protected with a liner while a lower periphery is unlined. The unlined portion can then be etched to form a widened region of the opening. Subsequently, the opening can be filled with insulative material to form an isolation region. Transistor devices can then be formed on opposing sides of the isolation region, and electrically isolated from one another with the isolation region. The invention also includes semiconductor constructions containing an electrically insulative isolation structure extending into a semiconductor material, with the structure having a bulbous bottom region and a stem region extending upwardly from the bottom region to a surface of the semiconductor material.

  • Patent number: 7211833
    Abstract: Semiconductor light emitting devices, such as light emitting diodes, include a substrate, an epitaxial region on the substrate that includes a light emitting region such as a light emitting diode region, and a multilayer conductive stack including a reflector layer, on the epitaxial region. A barrier layer is provided on the reflector layer and extending on a sidewall of the reflector layer. The multilayer conductive stack can also include an ohmic layer between the reflector and the epitaxial region. The barrier layer further extends on a sidewall of the ohmic layer. The barrier layer can also extend onto the epitaxial region outside the multilayer conductive stack. The barrier layer can be fabricated as a series of alternating first and second sublayers.

  • Patent number: 7182151
    Abstract: An apparatus and method for horizontally drilling for detecting subsurface features and avoiding such features during closed-loop control of an underground drilling machine. A horizontal drilling system includes a base machine capable of propelling a drill pipe rotationally and longitudinally underground. A cutting tool system is coupled to the drill pipe, and a control system controls the base machine. A detector is employed to detect a subsurface feature. A communication link is utilized for transferring data between the detector and the control system. The control system uses the data generated by the detector to modify control of the base machine in response to detection of the subsurface feature.

  • Patent number: 7097319
    Abstract: A lighting fixture is disclosed that has two lights sandwiching a pivotable reflector. An upwardly directed lamp is mounted on the reflector to pivot therewith. The down lamp may also be mounted on the reflector to pivot therewith, albeit it need not be. A lower shade can enclose the down lamp. To replace the lower lamp one can pivot the reflector to provide access to the burnt-out lamp.

  • Patent number: 7067361
    Abstract: SiC MESFETs are disclosed which utilize a semi-insulating SiC substrate which substantially free of deep-level dopants. Utilization of the semi-insulating substrate may reduce back-gating effects in the MESFETs. Also provided are SiC MESFETs with a two recess gate structure. MESFETS with a selectively doped p-type buffer layer are also provided. Utilization of such a buffer layer may reduce output conductance by a factor of 3 and produce a 3 db increase in power gain over SiC MESFETs with conventional p-type buffer layers. A ground contact may also be provided to the p-type buffer layer and the p-type buffer layer may be made of two p-type layers with the layer formed on the substrate having a higher dopant concentration. SiC MESFETs according to embodiments of the present invention may also utilize chromium as a Schottky gate material. Furthermore, an oxide-nitride-oxide (ONO) passivation layer may be utilized to reduce surface effects in SiC MESFETs.

  • Patent number: 7012554
    Abstract: A tracking device for tracking a vehicle in which a radio transmitter is powered by heat energy of the exhaust system of an engine propelling the vehicle. A thermoelectric module is attached to a hot portion of the exhaust system. Electrical power generated by the thermoelectric module is used to power the transmitter. A preferred tracking device consists of one thermoelectric module, one transmitter, a flexible finned plate for dissipating heat, and two high Curie temperature magnets for attaching the device to the vehicle's tail pipe. The transmitter is mounted on the flexible finned plate with a thermal insulator in-between them.

  • Patent number: 6999688
    Abstract: A receiver system processes a received optical signal that carries user information. The receiver system includes a splitter, a first converter, a second converter, and a detection system. The splitter splits the received optical signal based on polarization into a first optical signal and a second optical signal. The first converter converts the first optical signal into a corresponding first electrical signal. The second converter also converts the second optical signal into a corresponding second electrical signal. The detection system applies radio frequency detection to the first electrical signal to generate a third electrical signal. The detection system applies radio frequency detection to the second electrical signal to generate a fourth electrical signal. The detection system then combines the third electrical signal and the fourth electrical signal to form a fifth electrical signal that carries the user information.

  • Patent number: 6914343
    Abstract: An electric generator system for producing electric power from the environmental temperature changes such as occur during a normal summer day on Earth or Mars. In a preferred embodiment a phase-change mass is provided which partially or completely freezes during the relatively cold part of a cycle and partially or completely melts during the relatively hot part of the cycle. A thermoelectric module is positioned between the phase-change mass and the environment. The temperature of the phase-change mass remains relatively constant throughout the cycle. During the hot part of the cycle heat flows from the environment through the thermoelectric module into the phase change mass generating electric power which is stored in an electric power storage device such as a capacitor or battery. During the cold part of the cycle heat flows from the phase change mass back through the module and out to the environment also generating electric power that also is similarly stored.
