摘要： A redundant and diverse secondary control system mirrors a primary control system but has some fundamental structural difference as compared to the primary control system to prevent a spread of a security breach from the primary control system to the secondary control system. The secondary control system may operate on different hardware built on different software written with different programming language as compared to the primary control system while performing the same function as that of the primary system. By hardware coding the algorithm to produce actuation signals, software based viruses and worms cannot interfere with the secondary control system's operation. A monitor device receives actuation signals from both the primary and secondary controls signals to determine whether an error occurred and to provide correct actuation signals to the controlled system.

摘要： Data associated with at least one building condition or status is sensed by one or more sensors. The data from these sensors may be sent over a data bus and received by the central computer. In addition, a modulated signal may be transmitted by one or both of the transmitters across the data bus. The modulated signal is received at the receiver, which analyzes the received modulated signal, and determines whether an intermittent fault has occurred on the data bus based upon the analyzing. For example, the receiver may compare the received signal to an expected pattern and when a discrepancy exists, an intermittent fault is determined to exist. The receiver may also determine the location of the fault based upon the analysis.

摘要： A signal is conducted from a controller module onto a network via a first coupling. The signal is transmitted across the network and received at one or more receiver modules via one or more second couplings. At the one or more receiver modules, the received signal is analyzed and based upon the analysis, a determination is made as to whether a fault has occurred in the network and/or where the occurrence occurred.

摘要： A fault determination apparatus includes a housing. The housing includes a circuit board disposed there within. The housing is shaped and dimensioned for non-intrusive placement within an existing electrical system. The circuit board is configured to provide one of a transmitter or a receiver within a fault determination system. A first set of connectors is disposed at a first side of the housing and a second set of connectors disposed at the second end of the housing. The first set of connectors and the second set of connectors are directly connected through the wires provided inside the apparatus while at least one wires under fault monitoring are tapped to the circuit board and configured so as to be electrically coupled to the existing electrical system.

摘要： A distance from a measurement point to a fault in a three-phase circuit is determined. The measurement point is located at an output of a power sub-station and the three phase circuit has a loop circuit having an associated net fault line current and a ground current. A derivative of the net fault line current of the loop circuit as measured from the measurement point is calculated. An uncompensated distance to the sub-cycle fault using at least the derivative of the net fault current is determined, and configured, to compensate for the ground current of the loop circuit. The compensation is applied to the uncompensated distance to produce a compensated distance to the sub-cycle fault.

摘要： A lighting element is disposed in an array of lighting elements. At the lighting element, a lighting status of at least one neighboring lighting element is sensed. Independent of any other lighting element, a lighting adjustment for the lighting element by applying the sensed lighting status to a predetermined rule is determined. The lighting adjustment is applied to the lighting element to adjust an illumination of the lighting element.
