Abstract
An apparatus for detecting a person's presence without requiring the person to provide auditory or tactile input. The invention may be incorporated into an electronic device, such as a desktop computer or notebook computer. The embodiment may employ a variety of radiation emissions to determine when a person enters the embodiment's field of detection and, in response to the person entering, activate the electronic device. This may prove particularly useful where, for example, the electronic device consumes significant power and/or may suffer deleterious effects if left active for too long.
