  • Patent number: 9726705
    Abstract: An interface circuit for a bridge sensor has a switch that connects to a resistive bridge circuit. The resistive bridge circuit includes a first input terminal, a second input terminal, and a pair of resistive branches that connect between the first and second input terminals. Both of the resistive branches include an output terminal. The switch is connected to the first input terminal and is in series with both resistive branches for connecting and disconnecting a voltage source from the resistive branch output terminals.

  • Patent number: 5856953
    Abstract: Method for processing echoes received in an ultrasonic liquid gauging apparatus includes the steps of transmitting at time t.sub.1 ultrasonic energy from an ultrasonic transducer toward a fixed target and a liquid surface; producing a transmission pulse corresponding to the time t.sub.1 ; receiving during a predetermined cycle interval a number (i) of ultrasonic echoes after t.sub.1 and converting each echo into a corresponding echo pulse having an associated time of arrival t.sub.i+1 ; and calculating the liquid level based on an averaged time of arrival of the second echo relative to t.sub.1 when it is known that the liquid surface is low.
