Claim 20:
21. An ice machine comprising:
an ice maker comprising:
an ultrasonic bin sensor mounted to a body; and
a controller in electrical communication with the ultrasonic bin sensor and configured to control the ultrasonic bin sensor; and

a storage bin coupled to the ice maker and sized to receive ice, a lens of the ultrasonic bin sensor facing an interior cavity of the storage bin;
wherein the controller is configured to:
filter out a portion of a return signal of the ultrasonic bin sensor below a threshold voltage as part of controlling a level of ice stored inside the storage bin; and
filter out a portion of the return signal exceeding the threshold voltage for a length of time equal to or less than a predetermined time delay as part of controlling the level of ice stored inside the storage bin.
