Abstract: A security system is disclosed for detecting intrusions at a plurality of predetermined locations having moveable closure members. The system comprises a plurality of intrusion sensors disposed at the locations for detecting movement of the closure members. Primary and secondary optical fiber sensor lines are routed through the intrusion sensors, and primary and secondary scanning units pulse signals along the sensor lines and receive reflected signals back from the sensor lines. A processor processes the reflected signals to determine if a reflection and/or attenuation change has occurred in a reflected pulse signal signifying a prescribed level of unauthorized intrusion activity which matches a signature intrusion signal. In the event of a cut through in the sensor lines, the primary sensor line monitors the sensors downstream of the break, and the secondary sensor line is activated to monitor the sensors upstream of the break.

Abstract: It is possible to prevent an unauthorized read-out from both active tags and passive tags. Antenna emission is turned on and off by using a switch, or attenuated by using a resistor. A part of the antenna may be chipped. With these configurations, it is possible to lower the emission level of the antenna thus preventing an unauthorized read-out of important information from a remote reader.

Abstract: A sensor and alarm system having a power-on sequence. The system has a power supply permanently-like connected to a power line of a facility. There may be a power interrupt to the power supply, which may initiate a power-on sequence of alarms. The sequence of alarms may indicate whether the system is wired properly and operating normally. If the sequence does not occur in a pattern as expected, then there may be a problem with the system. Also, the sensor portion of the system may set off an alarm pattern if a sensed gas has a concentration greater than a first magnitude. The system may set off another alarm pattern if a sensed gas has a concentration greater than a second magnitude. If a sensing element of the sensor portion goes out of calibration, then the system may set off still another alarm pattern.

Abstract: A method and apparatus to provide evidence that a person who is intended to make a required inspection was actually physically present at a predefined location associated with the inspection, so that the inspection could have been done, and if not, to provide an indication of the failure to perform the inspection. This invention is particularly well suited to determine if required pre/post-trip inspections of vehicles have been performed. Detecting a triggering condition, such as powering on (or off) equipment, indicates the beginning of a period of time during which the inspection is to be performed. The monitoring system waits for a predetermined event to occur, which indicates the period of time has expired and determines if data corresponding to the inspection have been received. If not, it is concluded that the inspection has not been performed.
