Abstract

A apparatus for automatically de-energizing electrically operable equipment in response to a lack of animal activity, such as human activity, in a specified environment during predetermined time period. The apparatus utilizes a circuit (10) which is designed to detect activity which generates energy in a certain wavelength range and particuiarly, sonic energy. If sound is sensed in the specified environment within the time interval determined by timer (30), a signal is generated to energize or maintain energization of one or more electrical devices (38). Contrarywise, if no sound is detected within the predetermined time interval, there is a resultant de-energization of the electrically operable equipment. A control may be provided to adjust the predetermined time delay period. A control may also be provided for adjusting the sensitivity of the device.
