Abstract
A hand cleaning fluid dispenser for dispensing fluid onto a user's hand includes a time of flight sensor to determine a distance of a hand of a user below an outlet of the dispenser from which the dispenser when activated dispenses the fluid and a controller to activate the dispenser to dispense the fluid from the outlet when the hand is sensed to be within a predetermined range of distances below the outlet.
Claims20
A hand cleaning fluid dispenser for dispensing fluid onto a user's hand, the dispenser including a time of flight sensor to determine at successive times a distance of a moving object relative an outlet of the dispenser from which the dispenser when activated dispenses the fluid;
- the dispenser including a controller to activate the dispenser to dispense the fluid from the outlet when the distance of the moving object is sensed to be within a first set of predetermined distances below the outlet that fluid dispensed from the outlet will engage the moving object.
A device having a consumable attribute which is consumed during use and which is replaceable,
- the consumable attribute having a reference surface which varies in distance from a reference point as the consumable attribute is consumed,
- a time of flight sensor to determine a distance of the reference surface from the reference point,
- a controller to estimate the extent to which the consumable attribute is present in the device based on the distance determined by the sensor.
