Abstract

A trashcan assembly can include a body portion, a lid portion pivotably coupled with the body portion, and a sensor assembly configured to generate a signal when an object is detected within a sensing region. The sensor assembly can include a plurality of transmitters having a first subset of transmitters and a second subset of transmitters. A transmission axis of at least one transmitter in the first subset of transmitters can be different from a transmission axis of at least one of the transmitters in the second subset of transmitters. An electronic processor can generate an electronic signal to a power-operated drive mechanism for moving the lid portion from a closed position to an open position, such as in response to the sensor assembly detecting the object.
