  • Patent number: 10345416
    Abstract: A method and apparatus provides high-accuracy measurements of an electrical parameter across a broad range of parameter input values. In one embodiment, an intelligent electronic device (IED), e.g., a digital electrical power and energy meter, with a plurality of independently-adjustable gain factors measures a parameter, and calculates and stores calibration factors associated with known values of the measured parameter. The IED or meter applies the stored calibration factors when measuring unknown values of the measured parameter, to improve the accuracy of the measurement.

  • Patent number: 10348094
    Abstract: One or more techniques and/or systems are provided for facilitating a shutdown of output power from an energy panel arrangement to an inverter. A shutdown implementation module is coupled between an energy panel arrangement and an inverter that converts DC power from the energy panel arrangement to AC power for an AC power grid. A communication connection is established, over a power-line communication line, between the shutdown implementation module and a shutdown controller associated with the inverter. Responsive to identifying a loss of the communication connection or receiving a shutdown instruction over the power-line communication line, the shutdown implementation module shuts down output power from the energy panel arrangement to the inverter. The shutdown implementation module may be located within a threshold distance from the energy panel arrangement (e.g., within about 10 feet) so that the output power may be shutoff within a threshold timespan (e.g., within about 10 seconds).

    Abstract: Disclosed examples include an ESD protection circuit to protect an IC pad with high immunity against hot-plug surges, switching noise or other transient voltage conditions on the protected pad. The ESD protection circuit includes a clamp transistor and a trigger circuit responsive to rises in the protected pad voltage at or above a first slew rate to turn on the clamp transistor, as well as a second circuit coupled between the control terminal of the clamp transistor and a voltage supply node. The second circuit responds to rises in a voltage of the clamp transistor control terminal at a second, lower slew rate to reduce the voltage of the first control node to at least partially turn the clamp transistor off to reduce leakage current flow through the clamp transistor during transient voltage conditions on the protected pad.

  • Patent number: 9285854
    Abstract: This invention relates to a modular combined optical data and electrical power distribution network and related system. More particularly the invention relates to a system for bi directional high-speed distribution of data and the universal transmission of significant quantities of electrical power using composite cabling which is adapted for connection to a plurality of peripheral components and devices. Previous data networks, particularly in domestic environments, for example for controlling personal computers, laptops and peripherals such as printers and scanners required dedicated power supplies and resulted in a tangled mass of wires and cabling often seen as clutter and sometimes posing safety hazards. The invention overcomes this problem by providing a relatively low voltage continual power bus, in the form of a dual or multi-core wire, which typically carries up to 100-200 Watts per node and which is also capable of carrying high volumes of data traffic typically in excess of 1 GBit/sec.

  • Patent number: 9178738
    Abstract: A receiver is operated so as to receive data conveyed on an Orthogonal Frequency Division Multiplexed (OFDM) signal transmitted on a plurality of sub-carriers. Such operation includes ascertaining which of the plurality of sub-carriers have a channel quality that satisfies one or more criteria. Then, sub-carriers are selected based at least in part on whether they have the channel quality that satisfies one or more criteria. The receiver then fully processes data streams only from the selected sub-carriers, wherein fully processing data streams comprises sub-carrier channel estimation or sub-carrier equalization or both sub-carrier channel estimation and sub-carrier equalization.

  • Patent number: 9146135
    Abstract: A circuit arrangement for use in a utility meter includes a processing circuit, a magnetically-actuated switch, and a first circuit. The processing circuit has a first mode and a second mode. The processing circuit performs a first set of metering operations related to energy metering in the first mode, and a second set of operations in the second mode or sleep mode. The second set of operations has fewer operations than the first set of operation, and requires less energy. The switch has is coupled to provide a first output signal to the processing circuit. The first circuit is configured to generate a pulse signal responsive to the switch transitioning states, and is operably coupled to provide the pulse signal to the processing circuit. The processing circuit causes display of stored values responsive to receiving the pulse and receiving the first output signal.

  • Patent number: 8995247
    Abstract: A first network device detects at least a first orthogonal code included in a preamble of a network packet received at the first network device from a second network device in an orthogonal frequency division multiplexing (OFDM) communication network. The first network device determines whether the first orthogonal code included in the preamble is associated with an assigned orthogonal code for the first network device. The assigned orthogonal code for the first network device is orthogonal to other assigned orthogonal codes for other network devices in the OFDM communication network. An operational mode of the first network device is changed from a sleep mode to an awake mode in response to determining the first orthogonal code is associated with the assigned orthogonal code for the first network device.
