  • Damper actuator controller having an enthalpy sensor input
    Patent number: 5762420
    Abstract: A low-cost, accurate enthalpy sensor is described. The invention provides an on/off output which reflects the result of a comparison between the enthalpy level of a space and a predetermined setpoint. The sensor combines a signal representative of humidity with a signal representative of temperature to create a signal representative of enthalpy. The signal representative of enthalpy is compared with a predetermined setpoint to determine if the enthalpy level is above or below the setpoint. An output is then produced which indicates whether the output representative of enthalpy is above or below the predetermined setpoint.

  • Electronic aquastat in immersible capsule
    Patent number: 5340019
    Abstract: A liquid immersible electronic aquastat in which a temperature responsive element and substantially all associated electronic circuitry are arranged on a circuit board within a tubular capsule of liquid impervious material closed at one end and having a external diameter not exceeding 3/8ths of an inch so as to be interchangeable with industry standard aquastat temperature sensor mounting hardware and fittings.

  • Calibrated physical parameter value measurement system
    Patent number: 5274334
    Abstract: A circuit for measuring a parameter value by measuring the time required to charge a capacitor in a sensor RC circuit from a first to a second voltage includes a reference RC circuit whose capacitor is also charged between two voltage levels. The circuit is calibrated so that the time interval required to charge the reference capacitor may be used to improve the accuracy with which the parameter value is measured.

  • Integrated circuit interconnector
    Patent number: 4933810
    Abstract: A flexible film has electrical interconnections on each side. Through-film interconnects pass through openings in the film to connect the electrical interconnects on opposite sides of the film. Electrical contact patterns are formed on one side of the film to accomodate integrated circuit chips or other small electronic devices. Multi-chip circuits can be formed by connecting the chips to the pattern areas and connecting the patterns by way of the electrical interconnections on either side, or on both sides.

  • Conductive polymer film humidity sensor
    Patent number: 4298855
    Abstract: A humidity sensor utilizes a conductive polymer film that normally exhibits a variable resistance characteristic. The polymer film also exhibits a humidity responsive function that can be utilized while the temperature responsive function is balanced out. The device is capable of a high level of calibration by the use of laser trimming of the conductive polymer film resistors.
