摘要: An occupancy sensor that provides improved performance by the inclusion of a microprocessor that controls the sensing transducers and processes the received signal to optimize desired detection performance. The occupancy sensor includes a quadrature detection technique and automatic sensitivity adjustment that reduce false detection caused by air flow, hallway traffic and other noise sources. A fault detection method executed periodically detects fault conditions in the sensor or sensing area caused by component failure or obstructions in front of the sensor. Transmitter power is varied depending on the size of the desired coverage area. Since various ambient parameters such as line voltage, light level, and temperature may be easily and usefully monitored, the microprocessor may use these variables to make intelligent decisions in controlling electrical loads, such as building lighting and ventilation.

摘要: A network of routers is monitored by a monitoring server. Each router implements various security mechanisms to secure the operation of the routers. For example, each router comprises control logic that implements a security protocol dictated, at least in part, by contents of at least two separate external storage devices, each storage device separate from, but coupled to, one of the ports of said router.
