SENSOR IN A DISPENSING SYSTEM FOR ACOUSTIC DETECTION OF A CONTAINER AND CONTENT THEREOF

摘要

Embodiments of a sensor system for acoustic detection in a dispensing system of a container having a rim and content includes at least one controller coupled to the dispensing system for selectively triggering on and off the dispensing system; an ultrasound position sensor coupled to the at least one controller a) for emitting a first ultrasound beam towards a container-receiving location, b) for receiving ultrasound echoes indicative of a position of the container relative to a dispenser outlet, and c) for sending a first signal to the at least one controller indicative of the container position relative to the dispenser outlet; and an ultrasound fill sensor couple to the at least one controller i) for emitting a second ultrasound beam towards the container-receiving location, ii) for receiving ultrasound echoes indicative of the rim and content surface, and iii) for sending to the at least one controller a second signal indicative of the position of the content surface relative to the rim. In operation, the dispensing system is triggered on by the at least one controller when the first and second signals respond to respective first and second criteria and is triggered off when at least one of the first and second signals does not respond to the respective first and second criteria.
