Patent number: 5534850Abstract: An electrical circuit for use in occupancy detectors for preventing false triggering when a load such as a light is de-energized. The occupancy detector includes circuitry for providing an intermediate signal indicating detection of a target object. An output stage receives the intermediate signal and in response provides a trigger signal for energizing the light or other load. An RC network, having a characteristic charge decay time, is coupled to the output stage such that the characteristic charge decay time governs the duration for which the output stage asserts the trigger signal for energizing the light or other load. Output signals from the occupancy-detecting circuitry are applied to the RC network through a first transistor switch. A second RC network, having its own characteristic charge decay time, is provided and the trigger signal is applied to charge the second RC network.Type: GrantFiled: July 7, 1994Date of Patent: July 9, 1996Assignee: Larry C.

Patent number: 5514956Abstract: Tank bottom inspection apparatus of the magnetic flux leakage type having a powered release mechanism for reducing the magnetic attraction of the apparatus to the tank bottom. The apparatus is wheeled over the tank bottom surface and includes a magnet assembly disposed over the surface for inducing magnetic flux in the material under inspection and a sensor assembly for detecting magnetic flux leakage from the material indicative of magnetic anomalies. A powered actuator permits the operator to retract the magnet assembly away from the surface, reducing the magnetic attraction to the surface and thereby reducing magnetic resistance to movement of the apparatus over the surface. The operator retracts the magnet assembly for maneuvering the apparatus over and around obstacles on the surface with greatly reduced magnetic attraction to the surface. The operator is then able to return the magnet assembly to a precise inspection position for continued inspection of the surface.Type: GrantFiled: October 11, 1994Date of Patent: May 7, 1996Assignee: Industrial Sensors and ActuatorsInventors: Bruce W.
