ABSTRACT:
The present invention provides a system for reducing the unproductive consumption of energy by equipment primarily intended to be operated during the presence of a person or thing in the area of operation of the equipment. The system renders the equipment operable during the time a person or thing is present within the area of operation and for a short period of time immediately thereafter. Except for the short period of time immediately after the person or thing exits the area of operation, the system renders the equipment inoperable during the time the person or thing is absent from the area of operation. Maintaining the equipment operable during the short period of time after the person or thing exits the area of operation reduces deleterious recycling which would otherwise occur in the event the area of operation were reentered within the short period of time. The system comprises detecting means for providing a presence-detected signal when a person or thing is present within the area of operation and an absence-detected signal otherwise. The system also comprises delay means responsive to said detecting means for providing a delay signal for a short period of time after the detecting means starts providing the absence-detected signal. The detecting means and delay means are coupled to output means which provides an enabling signal when any of the presence-detected signal and the delay signal are present and a disabling signal otherwise.
