Patent number: 7586408Abstract: Occupancy sensors are provided that do not require an external power source in order to operate. The sensors operate with a low voltage non-rechargeable battery and are fully functional for at least about 15-20 years. The sensors include a relay output capable of switching high or low voltage and high or low current with virtually no generated heat. The sensors require no warm-up period, no minimum load, and no external ground connection. The sensors are always active and are easily installed, having two electrically interchangeable outputs for coupling to, for example, a load and a load power source.Type: GrantFiled: January 28, 2005Date of Patent: September 8, 2009Assignee: ABL IP Holding, LLCInventor: Philip H Mudge

Patent number: 6304180Abstract: An occupancy sensor is provided that can operate within an extended range of AC and DC input voltages, enabling the sensor to be used in different electrical environments. The sensor draws substantially only an amount of current required by the sensor at the moment, which reduces power waste. The sensor includes a relay that de-energizes when occupancy is sensed and energizes when occupancy is not sensed. This reduces peak sensor current, permitting the sensor to maintain a more constant average current. A shutdown mode is provided to prevent sensor damage or destruction should excessive output current be drawn from the sensor. The sensor also includes a second output at which occupancy signals are provided when an occupancy signal is present at the first output.Type: GrantFiled: April 14, 1999Date of Patent: October 16, 2001Inventors: Brian P. Platner, Philip H. Mudge, William J. Fassbender

Patent number: 6215398Abstract: Occupancy sensors are presented that include a flat lens for focusing detecting beams into narrower, longer range beams than those of conventional curved lenses. A sensing circuit generates a detecting beam that is substantially perpendicular to the flat lens. The flat lens has a plurality of lens segments that provide long, intermediate, and short range sensing beams. To facilitate positioning of an occupancy sensor, the sensor includes a plurality of indicators that indicate the sensor's long and short range sensing limits. An override timer circuit is provided that upon activation sets the occupancy sensor in occupancy mode for a predetermined time period. A warm-up timer circuit is also provided that upon power-up automatically sets the occupancy sensor in occupancy mode for a predetermined warm-up period. These occupancy sensors are well-suited for environments with long aisles, high ceilings, and high intensity discharge lighting.Type: GrantFiled: December 15, 1998Date of Patent: April 10, 2001Inventors: Brian P. Platner, Philip H. Mudge, William J. Fassbender, Keith K. Platner

Patent number: 5473202Abstract: A control unit for switching AC powered high efficiency lighting in response to a signal from an occupancy sensor. The lighting is switched by a hybrid mechanical relay/semiconductor switch. The semiconductor switch is connected in parallel with the relay switch contacts to protect them and is controlled by a noise-insensitive zero voltage crossing detector circuit which switches the semiconductor switch only at the zero crossings of the AC power. The semiconductor switch is preferably turned on by a pulse forming circuit only for a brief period of time spanning the time when the relay is switching.Type: GrantFiled: June 5, 1992Date of Patent: December 5, 1995Assignee: Brian PlatnerInventors: Philip H.

Patent number: 4644164Abstract: A compact passive infrared detector is provided with a plane mirror which reflects infrared radiation focused by a lens onto a detector arranged between the lens and the reflector.Type: GrantFiled: January 4, 1985Date of Patent: February 17, 1987Assignee: Cerberus AGInventor: Philip H.

Patent number: 4447726Abstract: A passive infrared intrusion detector is provided of the type having an infrared sensor for detecting a change in temperature in the field of view of the sensor caused by an intruder moving therein, optical means for focusing radiation from the field of view on the sensor, and an alarm which is activated when the sensor detects a change in temperature. The improvements reside in mounting the passive intrusion detector in a generally C-shaped housing exposed to a field of view which may be shifted through an angle of at least 180.degree.. A bendable, translucent window is provided having slots in opposite ends thereof which engage projections on opposite sides of the housing. The window is very simply released by applying thumb pressure to the window in the proximity of the projections. The intrusion detector is also provided with a horn-like enclosure which surrounds the sensor. A flexible Fresnel lens may be rapidly mounted on the enclosure, permitting ready adaptation of the detector to local conditions.Type: GrantFiled: April 16, 1982Date of Patent: May 8, 1984Assignee: Cerberus AGInventors: Philip H. Mudge, William G. Kahl, Jr.

Patent number: 4275303Abstract: The invention comprises a passive infrared intrusion detector including a lamp for locating the zones being protected by the detector. The detector includes a heat sensor, a lens system for receiving and focusing the body heat of an intruder on the heat sensor, and electrical circuitry responsive to the heat sensor for actuating an alarm or detection signal when the body heat of an intruder is detected.The zone locator lamp is positioned near the heat sensor and its light passes through a lens in the general direction of a zone to be protected. The light parallels a portion of radiation which is focused on the heat sensor by another lens. If the light can be observed from a given position in front of the detector, that position is in a zone being observed by the detector and body heat radiated from that zone will be focused on the heat sensor. Thus, zones protected by the intrusion detector can be established by adjusting the position of the detector until light from the zone locator lamp is observed.Type: GrantFiled: November 13, 1979Date of Patent: June 23, 1981Assignee: Arrowhead Enterprises, Inc.Inventor: Philip H.

Patent number: 4215271Abstract: An improvement in a photoelectric intrusion detector unit of the type designed to resemble a duplex electrical outlet. An angled mirror and a collimating lens are supported on a common mount which is rotatable about an axis of rotation which is angularly displaced from the optical axis of the lens but passes through its focal point. The optical axis of the lens describes a conical surface about the axis of rotation.Type: GrantFiled: November 6, 1978Date of Patent: July 29, 1980Assignee: Arrowhead Enterprises, Inc.Inventors: Philip H. Mudge, Richard Settanni, William G. Kahl, Jr.
