摘要： A universal sensor has a selectively scaled condition responsive element such as a capacitive pressure transducer mounted on a common support with signal conditioning means embodied in an integrated circuit to provide a control signal precisely corresponding to a sensed condition. Electrically actuatable means on the support are incorporated in the circuit for low cost, mass producible calibration of the circuit and condition-responsive element relative to each other after assembly on the common support. Preferably, a capacitive pressure transducer and a reference capacitor are arranged in a charge-locked loop relation with a common node while an array of switches cycles the voltage across the transducer and reference capacitors with opposite transitions with a predetermined frequency so change in transducer capacitance results in a differential voltage at the common node. That voltage is amplified to drive a current source-sink-integrate network and adjust sensor output voltage to restore a balanced condition at the common node and maintain sensor output voltage at a level inversely proportional to transducer capacitance. The sensor is adapted for calibration to provide an electrical calibration signal for actuating calibration means such as electrically settable potentiometers, or serially programmed digital-to-analog converters or the like to provide bias and gain and non-linearity calibration in the sensor. In one embodiment, calibration is achieved by adjustment of variable capacitors.

摘要： The present disclosure includes a system and method for passively transferring radio frequency signals. In some implementations, a signal transfer element configured to passively transfer RF signals between a first region of a container and a second region of the container includes a first antenna, a second antenna and a coaxial transmission line. The first antenna is configured to wirelessly receive and transmit RF signals and passively transfer wirelessly received RF signals to a first end of a coaxial transmission line. The second antenna is configured to wirelessly receive and transmit RF signals and passively transfer wirelessly received RF signals to a second end of the coaxial transmission line. The coaxial transmission line is configured to passively transfer RF signals between the first antenna and the second antenna. A leg of the first antenna, a leg of the second antenna, and a center conductor of the coaxial transmission line are formed from a continuous conductor independent of physical connections.

摘要： A pressure sensor has a pressure responsive capacitor electrically connected to a signal conditioning circuit which is calibrated after mounting in a housing to provide an electrical signal corresponding to an applied pressure. The capacitor has thin metal capacitor plates on facing surfaces of a ceramic diaphragm and base and is adapted to receive an applied pressure on the diaphragm. Terminals from the capacitor are disposed on an opposite surface of the capacitor base; the circuit has a flexible substrate having a first end overlying the opposite base surface mounting circuit components electrically connected to the capacitor terminals and has an opposite end folded over the first end electrically connected to connector terminals on a connector body overlying the base; and the housing includes a metal sleeve fitted over the capacitor and body having a rim clamping the capacitor and connector body together to form the sensor. The connector body has a tubular portion open at both ends accessible from outside the body and extending to the flexible circuit to permit circuit calibration through the tubular portion and has an encapsulant therein sealing the body after calibration. Circuit pads capacitively coupled to ground connections at each end of the flexible circuit substrate are provided on substrate tabs which extend between the body and housing rim to be clamped in electrical engagement to each other and to the housing to provide improved electromagnetic compatibility for the sensor.
