摘要： The present technology involves a method and apparatus for detecting and reporting magnetic fields in the proximity of a utility meter as an approach to determining tampering of such meter. The sensitivity level of the magnetic field sensors may be adjustable allowing either remote or local sensitivity adjustments to a magnetic field sensor to compensate for variations in the electromagnetic environments of different meter installation sites. Alternatively, the output of each magnetic field sensor may be connected to the input of an adjustable threshold circuit. When the output voltage of the magnetic field exceeds a predetermined threshold voltage, a magnetic event signal is generated. Threshold adjustments to the adjustable threshold circuit may be performed locally at the meter site or remotely from a station. The output of each magnetic field sensor may be monitored by a locally or remotely programmable magnetic sensor output monitor. Such magnetic sensor output monitor generates a magnetic event signal when a predetermined number of magnetic sensors have been activated.

摘要： A portable data storage device compatible with both standard and high definition digital video cameras is provided. The device includes at least one SDI I/O, and preferably at least one audio I/O and preferably at least one medium speed I/O interface. A device controller takes the high speed serial data, packetizes it, and then sends it out to a plurality of memory modules. Preferably each memory module includes four NAND clusters, each NAND cluster consisting of a flash memory controller and two NAND flash memories. Interposed between the device controller and the memory modules are a plurality of memory controllers, each memory controller controlling a group of memory modules. A user interface is coupled to the device controller, the interface including a display capable of at least two user-selectable orientations, record/playback controls and a four-way directional control pad.

摘要： A voltage acquisition circuit for sensing input voltage signals in each phase of an electrical service includes a non-active current transformer configuration that is operable over a wide input voltage range. The current transformer configuration includes primary and secondary windings, an input resistor and a burden resistor across which an output voltage is defined. The input resistor may be relatively large, such as on the order of about one MΩ and the transformer core may have a nanocrystalline core characterized by predictable magnetic properties versus varied transformer flux levels. This operational predictability facilitates phase compensation via digital filtering or otherwise for any phase shift induced between input and output voltages of the current transformer. The subject voltage acquisition circuits may be provided to sense each phase of a single-phase or polyphase electrical service, whereby the sensed voltages are subsequently provided to additional components of an electricity meter, such as a power supply or other processing components, including an A/D converter and microprocessor for determining energy quantities.
