摘要:
Disclosed is an array for contactless transmission of electrical signals or energy from at least one transmitter to several receivers. The invention is characterized in that each transmitter contains an alternating current source or a source of current and several inductive coupling elements powered by the latter, which are transformed into resonance-capable elements by a capacitor, in addition to a control element that controls the alternating current source or the source of current in such a way that it operates at a resonance frequency of the resonance-capable element.

An isolator system is disclosed in which a pair of circuit systems is separated by an isolation barrier but engage in mutual communication by an isolator device that bridges the isolation barrier. A first circuit system may include a measurement system generating measurement data and status monitor generating status data. The first circuit system also may include a communication system that multiplexes the measurement data and the status data for transmission across a common isolator device. In this manner, the number of isolator devices may be reduced over conventional designs.

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.

A sealed container (10) is provided with a sensor (12, 26, 36) capable of monitoring the physical and/or chemical condition of materials stored in the container. The sensor may or may not have its own power source. In the embodiment where the sensor does not have a power source, a communicator induces a signal in the sensor and receives a return signal with the desired data. The container may be a metal or a nonmetal.

A remote control device is provided. The remote control device includes a shell (1) configured with a thermoelectric generation module (3), a central processor (2), a button module (4) and a RF module (5). The thermoelectric generation module (3) is connected with each of the other modules (2, 4 and 5). The central processor (2) is connected with the button module (4) and the RF module (5). The thermoelectric generation module (3) includes an electricity generation unit (31). The electricity generation unit (31) includes two metal sheets (311 and 312) which are made of different materials and form a closed loop circuit via two connection points (A and B). The electricity generation unit (31) is able to generate a thermoelectromotive force based on a temperature difference between the two connection points (A and B), and powers the other modules (2, 4 and 5) by the thermoelectromotive force.
摘要:
A connector assembly for transmitting high-frequency signals comprises at least one pair of coupling faces for the differential transmission of a non-inverted signal and of an inverted signal. The connector assembly further comprises at least one transmitter and one receiver. To obtain a compact connector assembly, which is constructed symmetrically having optimal transmission properties, the coupling faces in same are constructed in a point-symmetrical manner.
