초록

A system and method for short-range ultrasonic detecting of a target is proposed herein to be used for example in a liquid-dispensing system such as those provided in home refrigerators. The system comprises a sensor assembly including a transmitter and a receiver positioned side by side so as to yield respective transmitting and receiving beams which overlap to define an asymmetrical shaped detection area, a controller coupled to both the transmitter and receiver to activate the transmitter and for receiving echoes indicative of the target from the rece...

청구항

1. A system for short-range ultrasonic detecting of a target; the system being part of a dispensing system including a spigot end that defines a dispensing direction; the system for detecting a target comprising: a sensor assembly that operates in the time domain including an ultrasound transmitter and an ultrasound receiver positioned side by side so as to yield respective transmitting and receiving beams that are oriented generally perpendicularly to the dispensing direction and which overlap at a first predetermined location distanced from the sensor ...
