20090293190 | SHOWERHEAD PRESENCE DETECTION SYSTEM - A system for accurately detecting the presence of a person in a shower by combining presence detection technology, such as an infrared sensor in the showerhead, with a mechanical height adjustment of the showerhead, so that the optimal distance between the sensor and showering person can be maintained for persons of different heights. Alternative embodiments include an electronic control unit to provide power consumption management and safety features. When the electronic control unit is combined with presence detection to predict the identity of a showering person, personal services customized for the identified person are provided. An alternate embodiment teaches a process for intelligently conserving water by intelligently blocking water flow at appropriate times, based on predictable behavior of a contemplated showering person. | 12-03-2009 |
