摘要： An enclosed metering and protective electrical apparatus includes an enclosure, a meter socket within the enclosure structured to input a power circuit and to engage a power meter, and a circuit interrupter within the enclosure including an operating handle and a trip mechanism. The circuit interrupter is structured to output the power circuit from the meter socket to a load and to interrupt the power circuit. A neutral current sensor within the enclosure is structured to detect a ground fault operatively associated with the power circuit and responsively cause the trip mechanism of the circuit interrupter to interrupt the power circuit. A disconnect handle substantially external to the enclosure includes linkage extending within the enclosure and cooperating with the operating handle of the circuit interrupter to open and close the circuit interrupter.

摘要： A transfer system includes an energy meter, a transfer switch, an automatic disconnect device, and a detector. The energy meter includes an input structured to receive a first power source, and a power output. The transfer switch includes a first input electrically connected to the power output of the energy meter, a second input, an output, and a mechanism structured to transfer one of the first and second inputs to the output of the transfer switch. The automatic disconnect device includes a first input structured to receive a second power source, a second input, an output, and a mechanism structured to electrically connect or disconnect the first input and the output of the automatic disconnect device responsive to the second input. The detector is structured to detect presence of the energy meter and output a corresponding signal to the second input of the automatic disconnect device.

摘要： An in use table manager in a computer system uses an in use table to track the use of files, or objects. The in use table is used to determine which objects may need recovery in the event of a system failure. Object addresses are hashed by the in use manager to identify a preferred slot in the table. The slots contain information identifying the object, and indicating the extent of use of the object. The in use manager assigns alternate slots, and dynamically changes the size of the in use table to reduce contention for slots. Several atomic operations on the table ensure integrity of the table, while permitting concurrent use. Portions of the table are bundled into single I/O operations to enhance system performance by minimizing I/O.
