    摘要： An arrangement for transmitting measured values from a plurality of acquisition points to a central station which includes transmitting/receiving devices which are assigned to the acquisition points and the central station. The measured value transmission is via a pipe network. The transmitting/receiving devices are accommodated in a housing (64) which is provided with an electrically conductive coating (72). Control and information signals to be transmitted are coupled in the form of high-frequency oscillations galvanically or capacitively into the pipe network (36) and/or galvanically or capacitively tapped from the pipe network (36).

    摘要： The output from a strain gauge bridge 13 on a shaft is transmittedtoafixeddetector27,29,31 using only twocoupl- ing capacitors 19, 23, and 21,25, each with a rotating plate 19 or 21 and a fixed plate 23 or 25, by applying the voltage from the bridge to a voltage to frequency converter 15 also mounted on the shaft. The converter 15 provides a square wave signal with frequency proportional to strain. This is received by the detector circuit as a differentiated square wave. A squaring amplifier 29 and frequency to voltage converter 31 reconstitute a voltage proportional to strain.

    摘要： The invention relates to the coupling of a sensor element to a transponder, the connection of said sensor element to the transponder being achieved by capacitive or inductive coupling. This enables any separation layer that may lie between the sensor element and the transponder to be retained, allowing the invention to be advantageously used in gas and liquid-tight containers, such as tyres. In addition, electrically non-conductive materials of the object to be measured can be used as a dielectric for the capacitive coupling and electrically conductive parts can form part of a conductor loop for the inductive coupling.

    摘要： A low-cost system for wireless, bi-directional transformation of electric signals over a capacitive interface between a host unit and a guest unit is provided. The system allows a high impedance in the circuitry of the guest unit to obtain a good signal transfer ability in conditions of poor dieelectric materials, poor conductivity in the contact pads and relatively large gaps between the contact pads. The capacitive interface comprises a respective first (A1; B1), second (A2; B2) and third (A3; B3) conductive area in the host and guest units (10, 40). The first conductive area (A1) of the host unit is connected to a self-tuning frequency generating resonant circuit (16) in the host unit (10) for obtaining high gain of signals transmitted to the guest unit (40). The second and third conductive areas (A2, A3) of the host unit are connected to an impedance circuit (30) in the host unit for receiving signals from the guest unit. The first and second conductive areas (B1, B2) of the guest unit are further connected to an impedance circuit (44) in the guest unit for receiving signals from the host unit. In a preferred embodiment, the first and third conductive areas (B1, B3) of the guest unit are also galvanically interconnected.
