Abstract
There is disclosed an in-line free-form sensor for controlling power flow to a utilization device. The in-line sensor is contained within a housing attached along a power cord and the housing contains no externally-visible moving parts. The sensor can be trained to respond to certain stimuli, such as light, sound, temperature, human presence, and/or motion. The sensor can control the power directly by operation of a switch or can provide signals for use by a device external to said housing.
