| 20090015405 | TAMPER DETECTOR FOR A SECURITY SENSOR - A security arrangement includes a mounting device having an upstanding wall. The mounting device is mounted to a surface of a structure such that the wall is oriented substantially perpendicular to the surface. A security sensor senses an event that occurs outside of the security arrangement. A tamper detector is attached to the security sensor and includes an optical emitter, an optical receiver, and a slot disposed between the emitter and the receiver. The emitter transmits optical energy that is received by the receiver through the slot. The wall of the mounting device is received in the slot when the tamper detector is coupled to the mounting device to thereby block the transmission of the optical energy from the emitter to the receiver. A controller is communicatively coupled to the receiver and produces a tamper signal in response to the receiver receiving the optical energy. | 01-15-2009 |
| 20090026355 | OFFSET OPTICAL SECURITY SENSOR FOR A DOOR - A security sensor apparatus senses movement of an object. The sensor apparatus includes an electronics arrangement having an optical emitter and an optical receiver. The optical receiver has an axis of reception. The optical emitter emits a first beam along an axis of emission in an emission direction. The axis of emission diverges in the emission direction from the axis of reception at an angle of at least two degrees. The electronics arrangement is mounted in association a first surface of the object or a second surface of a structure disposed in opposition to the first surface. A reflector arrangement includes at least one reflective surface and is mounted in association with the other of the first surface and the second surface. The at least one reflective surface receives at least a portion of the first beam and produces a second beam directed at and received by the optical receiver. | 01-29-2009 |

| 20100128123 | SECURITY SYSTEM INCLUDING LESS THAN LETHAL DETERRENT - A security system includes a video system for capturing images of an intruder. A deterrent dispensing device dispenses a deterrent substance in a selected direction. An actuator module is communicatively coupled to the video system and is coupled to the deterrent dispensing device. The actuator module receives a video signal from the video system and, in response thereto, controls the deterrent dispensing device to thereby aim the dispensed deterrent substance in a direction of the intruder. | 05-27-2010 |
| 20100128446 | SECURITY SYSTEM INCLUDING MODULAR RING HOUSING - A modular building system arrangement includes a plurality of electrical building systems. Each electrical building system has a housing with a mechanical connector that is connectable with a like connector of each other building system housing. Members of any subset of the building system housings are connectable with each other to form a building system assembly. The building systems of the building system assembly conjointly define an electrically conductive pathway interconnecting each of the building systems of the building system assembly. The pathway carries power and/or data. | 05-27-2010 |
| 20100194564 | SECURITY SYSTEM INCLUDING PHOTOBEAM CARRYING STATUS INFORMATION - A security method includes transmitting an optical beam from a battery-powered transmitter. The beam carries a tamper signal and/or a battery status signal. The beam is received at a receiver. A radio frequency signal is transmitted from the receiver to a controller. The radio frequency signal includes an alarm signal if there is an interruption of reception of the beam at the receiver. The radio frequency signal is dependent upon the tamper signal and/or battery status signal. | 08-05-2010 |
| 20100247106 | AUTOMATICALLY ALIGNING PHOTOBEAM ARRANGEMENT - A method of aligning an optical beam includes transmitting a first beam from a first optical transceiver to a second optical transceiver. A position of the second optical transceiver is adjusted based upon the received first beam. A second beam is transmitted from the second optical transceiver to the first optical transceiver. A command signal is transmitted from the second optical transceiver to the first optical transceiver. In response to the command signal, a position of the first optical transceiver is adjusted based upon the received second beam. | 09-30-2010 |
