Abstract
A power interrupt device for detecting activity remote from the detector and/or device and for producing a signal capable of interrupting power to a load, such as an electronic display. The detector can sense remote activity, and the activity or associated object need not contact the detector. Depending upon whether the activity is present or not present, the detector and associated interrupt circuitry can turn on or off a power load device such as an electronic display. The power interrupt device is well suited for turning off an electronic display when a user is no longer in the room or working area. The computer can remain running, however, the associated display can be remotely turned off to reduce the amount of heat dissipated from the display during periods when the user is not present.
