Since a number of frequencies can be sensed as well as their relative positions, the technique provides a large number of potential identification possibilities. Pucks can be used to identify a user, a technician, a recipe, a set of instructions, or a control routine. Currently, one big area of interest is the use of Sensopad in timers, where more intuitive user interfaces can be designed. For example, the pucks can be embedded into the hands of a clock so that a user may simply move the hands to indicate a start and stop time, a method that is less expensive to implement and easier to use than conventional timers. Since there is no need for a mechanical connection between the puck and the sensing circuit, the pucks may simply be removed by the user for cleaning or when not in use.
Removable controls can also serve as a safety feature where children are present.
The absence of a physical connection also enables waferproof enclosures to be easily engineered. Sensopad can also be used inside an appliance. One example is the sensing of water level in a washing machine or dishwasher. This can be done by either measuring the displacement of a flexible membrane, as in the traditional pressure switch or, more accurately with measuring the position of a floating puck. Numerous other possible sensing applications exist inside appliances.
