Abstract: A system for detecting a buried conductor comprises a transmitter for generating a test signal in the buried conductor and a detector for detecting an electromagnetic signal resulting from the test signal flowing in the buried conductor. The transmitter comprises a waveform generator for generating a drive waveform signal, a power supply, an amplifier, connected to the power supply and the waveform generator for producing an output drive signal based on the drive waveform signal and an output circuit for acting on the output drive signal to generate an output signal having a current and a voltage. In-phase and quadrature components of the current and voltage of the output signal are fed back for controlling the amplifier.

Abstract: A detector for calculating the distortion of an electromagnetic field produced by a buried current carrying conductor comprises three antennas B, M, T. Outputs of two pairs of antennas are compared and the depth of the buried conductor is calculated using two different methods. If there is a significant difference in the two calculated depths then it is deemed that the electromagnetic field produced by the buried current carrying conductor is significantly distorted by the material in which the conductor is buried.

Abstract: A detector for calculating a depth of a buried conductor comprises three parallel antennas B, M, T. The second antenna M is spaced a distance s from the first antenna B and the third antenna T is a distance 2s from the first antenna B and a distance s from the second antenna M. The outputs of the first and second antennas B, M are compared and the outputs from the second and third antennas M, T are compared. The depth of the buried conductor is calculated based on the first and second compared values.

Abstract: A cholesteric liquid crystal display device (24) has a protective sheet (40) or a stack of protective sheets adhered to the substrate (11) at the front of a stack of cells (10B, 10G, 10R) containing cholesteric liquid crystal material (19). The protective sheet is adhered by a layer of adhesive (40) which is either an adhesive curable by heat or an adhesive curable by light. The adhesive contains a UV blocking agent, for example, a compound based on benzophenone, having a property of reducing the transmission of ultra-violet light through the adhesive. The protective sheet (s) provides protection to the display device and may be made of glass or plastic. Adhering the protective sheet (s) with an adhesive provides the advantages of being much cheaper to implement than laminated glass and of allowing the adhesive to contain the UV blocking agent for UV protection of the cholesteric liquid crystal material.

Abstract: A keyless control system for a motor vehicle or other structure operates to activate a device associated with the structure. The system includes a smart relay operating in conjunction with a control circuit, and a signal receiver which activates the relay upon receipt of an appropriate control signal. The signal may be an electromagnetic signal or an acoustic signal.

Abstract: A torque arm assembly for a backstopping clutch is provided that enables load sharing among multiple torque arm assemblies, controlled release of load on the torque arm assembly and load sensing. The torque arm assembly includes a head member that is connected to an outer race of a backstopping clutch and defines a pair of attachment points. One end of an arm member is pivotally connected to one attachment point of the head member while the other end of the arm member is connected to a stationary structure. A strut extends between the other attachment point of the head member and the arm member. Upon backstopping action by the clutch, the head member rotates slightly against the force of the strut allowing other torque arm assemblies to receive a portion of the system load. Movement of a strut seat then allows controlled release of the load tension.
