    摘要： A pressure sensor includes an optical transmitter transmitting a dispersive light toward two optical receivers, all carried in a housing. Pressure changes on the housing cause the light beam to be deflected with the amount of deflection measured by the difference in light received by each of the two receivers. A processor operable with the receivers provides a pressure measurement responsive to the light beam deflection.

    摘要： A rocker styled switch includes an arm member moveable into and out of a beam path transmitting light between an optical transmitter and an optical receiver for blocking and allowing light to reach the receiver for providing an actuating signal. An end of the arm member includes a cam follower moveable along a contoured cam surface for causing a preferential movement of the arm member from an unstable position to a stable position responsive to the cam surface for defining a switching operation. Interchangeable cam surfaces provide a one position momentary switch, a two position momentary switch, a two position stationary switch, and a three position stationary switch.

    摘要： A detector or a modulator for converting between optical and radio frequency signals comprising an optical guide (11 to 14) for propagating two optical signal components having frequencies that differ by an amount corresponding to a radio frequency and a microstrip radio signal guide (15, 16) for propagating a radio signal at the radio frequency, the microstrip radio signal guide being in travelling-wave coupling with an interaction one (14) of the optical guide comprising material in which interaction between the optical signal components and the radio signal occur. The microstrip radio signal guide element (15, 16) comprises an electrically conductive strip (15) juxtaposed with and extending along the interaction zone (14) on one side thereof and an electrically conductive ground plane (16) juxtaposed with and extending along the interaction zone (14) on an opposite side thereof. Transition radio signal guide elements (20,21) in the form of Vivaldi antennas extending transversely to the microstrip (15) connect the microstrip radio signal guide element (15,16) with a rectangular section wave-guide (18) and a matched load. Each of the transition radio signal guide elements (20, 21) comprises an opening of progressively varying width formed in the electrically conductive ground plane of the microstrip guide (16). Radio frequency signal resonators (24 to 27) extend the ends of the microstrip (15) and the small ends of the Vivaldi antennas.

    摘要： A receiver (103) for receiving an Ultra Wide Band (UWB) signal comprises a receiver front end (105) coupled to symbol point correlators (107). The symbol point correlators (107) comprise a first plurality of correlators which generates correlated signal values around a first symbol decision point of a first symbol by correlating the received UWB signal with a local replica. The first plurality of correlators are time offset with respect to each other to generate first time offset correlated signal values. The time offsets are typically significantly less than the timing jitter of transmit and receive oscillators. The symbol point correlators (107) are coupled to a joint estimator (109) which determines a symbol value of the first symbol in response to the first time offset correlated signal values by joint detection of the symbol value and a time offset of the UWB signal. The invention may effectively reduce time jitter noise to a value determined by the relative time offset between the correlators.

    摘要： In an orthogonal frequency division multiplex communication system, for example a HIPERLAN/2 system, power amplifiers (224) of mobile terminals (4, 6) are switched off when not in use, and then switched on again when a signal transmission is to be made. This conserves power, but introduces a power amplifier transient (315). An access point (2), i.e. a type of base station, compensates for these power amplifier transients (315) using a simple scalar constant gain transient correction, over a full OFDM symbol (or a plurality of OFDM symbols). The correction is updated on an OFDM symbol by symbol basis (or plurality of symbols by plurality of symbols basis).
