Abstract: A liquid level measurement system includes a liquid receptacle including a side wall and a guided wave sensor array coupled to the wall. The guided wave sensor array is configured and adapted to emit induced guided waves. A method for detecting a liquid level in a receptacle using a liquid level measurement system includes emitting induced guided waves from a first guided wave sensor array coupled to a wall of a liquid receptacle thereby generating transmitted guided waves. The method includes detecting the transmitted guided waves with at least one of the first guided wave sensor array or a second guided wave sensor array. The method includes determining a liquid level of the liquid receptacle using the detected transmitted guided waves.

Abstract: A laser diode drive system configured to output a drive signal to control a voltage provided to a laser diode can include a circuit sensor system configured to output a sensed signal indicative of a drive current of a laser diode, and a temperature sensor configured to output a temperature signal indicative of a temperature of the laser diode or an ambient temperature of the laser diode. The system can include a temperature compensation system configured to output a correction signal based on the temperature signal to compensate for a temperature dependent factor in the sensed signal.

Abstract: A resistance measurement system can include a plurality of resistors connected in series along a single line. The plurality of resistors can include N resistors. The system can include a plurality of capacitors for at least N-1 of the resistors. Each capacitor can be connected in parallel to the single line with a respective resistor to form a respective resistor-capacitor (RC) pair. Each RC pair can include a different time constant such that each RC pair reaches a steady state voltage at a different time. The system can include a current supply connected to the single line to supply a current to the line. The system can include a control module configured to sense a total voltage across the single line and to successively determine resistance of each resistor from the total voltage based on the current, a known total steady state voltage, and known time-to-steady-state-voltages of each RC pair and/or resistors.
