Abstract: A flow control apparatus comprising a housing capable of receiving a portion of the feeding set, a pumping device configured to receive the feeding set and may produce a fluid flow in the feeding set and deliver fluid to a subject, an ultrasonic sensor may be configured to produce a sensor signal indicative of a condition of the feeding set, and a control circuit in communication with the ultrasonic sensor for receiving the sensor signal from the ultrasonic sensor indicative of the condition of the feeding set. The ultrasonic sensor may comprise a plurality of sensor components which may be configured to emit an ultrasonic signal in a first direction, and in a second direction opposite the first direction through the feeding set.

Abstract: An improved cash box system for a bill validator (11) which includes bill inlet (16) a sensor (OS) associated with the opening, a bill transporting assembly (21) and a bill stacking assembly (30). A cash box (10) associated with the bill validator (11) receives bills (B) from the bill stacking assembly (30) when the stacker motor (M2) is activated. A processing system (100) measures the current draw of the stacker motor (M2) and compares it to a predetermined limit of the current draw to determine whether the cash box (10) is full, when a bill is placed in the bill inlet.
