Abstract

A delivery device including a) a housing, b) a container for a fluid arranged in the housing, the container having an opening, c) a delivery conduit connected in fluid communication with the opening, the conduit having a front end in flow respect distal from the container and a rear end in flow respect proximal to the container, the front end and the rear end defining an axis therebetween and a forward direction and a rearward direction, and d) a pump arranged to deliver fluid at least in a direction from the container through the conduit, the device comprising, a sensor able to change state in at least one respect in response to a predetermined proximity of an object to the sensor in a sensing direction, a converter, separate from or integral with the sensor, converting at least one of the sensor states into an electromagnetic signal, and a processor, receiving the electromagnetic signal and delivering a control signal to an operational component of the device.
