    Abstract: A method for monitoring a linear compressor is provided. The method includes determining a velocity dependent induced voltage in a driving coil of the linear compressor, extracting a higher order harmonic from the velocity dependent induced voltage, and establishing that a piston of the linear compressor is crashing if the higher order harmonic is greater than a reference value.

    Abstract: A method for operating a linear compressor is provided. The method includes supplying a motor of the linear compressor with a time varying voltage and estimating a back-EMF of the motor of the linear compressor. The method also includes determining a velocity of the motor of the linear compressor based at least in part on the back-EMF of the motor and calculating a stroke length of the motor of the linear compressor based at least in part on the velocity of the motor.

    Abstract: Systems and methods for receptacle auto fill using inductive sensing are provided. One example system includes a dispensing system capable of dispensing liquid. The system includes a sensor. The sensor includes a coil positioned adjacent to a dispensing area of the dispensing system. The system includes a receptacle capable of holding a volume of liquid. The system includes a floating object positioned within the receptacle and permitted to move upwards and downwards based on a liquid fill level of the receptacle. The floating object includes a conductive strip providing a first impedance at a first vertical position of the strip and a second impedance at a second vertical position of the strip. The first impedance is different than the second impedance. The system includes a controller configured to control the dispensing system based at least in part on an amount of inductance exhibited between the coil and the conductive strip.

    Abstract: A method for operating a linear compressor is provided. The method includes estimating an acceleration of the motor of the linear compressor using at least a robust integral of the sign of the error feedback. A position of the motor of the linear compressor when the motor of the linear compressor is at the bottom dead center point is also determined based at least in part on a measured current to the motor of the linear compressor and an estimated acceleration of the motor. The position of the motor of the linear compressor when the motor of the linear compressor is at a top dead center point is calculated based at least in part on the position of the motor of the linear compressor when the motor of the linear compressor is at the bottom dead center point and a stroke length of the motor of the linear compressor.
