A smart radio frequency identification (RFID) system for controlling operation of electrical units is disclosed. The system includes a RFID tag, a control unit coupled to the RFID tag, a relay unit connected to the control unit and to the electrical unit, and an external RFID reader for generating radio frequency (RF) signals for sending data to the RFID tag when the RFID reader is placed next to the RFID tag. The RFID tag checks and stores the data and passes the data along to the control unit. The control unit sends a control signal to the relay unit in accordance with instructions contained in the data, causing the relay unit to operate the electrical unit between a first state and a second state. The system may also include sensors to monitor certain conditions of the electrical unit and cause the control unit to turn off the electrical unit when the conditions are abnormal.

An information terminal includes: a first communication unit that performs wireless communication with a wireless base station connected to a wide area network; a second communication unit that performs communication by a communication scheme different from the first communication unit; and a controller that: controls the second communication unit to receive first management information from a power management system that is installed in a facility and includes a storage battery, the first management information including information relating to the storage battery; and controls the first communication unit to transmit second management information generated based on the first management information received, to a server outside the facility as a destination, the server being connected to the wide area network.

The present disclosure relates to using a coating to protect a portion of an optical fiber that is intended to buckle within a fiber optic connector. The fiber optic connector can include a bare fiber optical connector.

Power systems, devices, and methods include a plurality of network interfaces for providing communication to, e.g., a management server, console, or user interface. One or more controllers coupled to power circuitry determine whether a preferred one of the network interfaces has connectivity, and directs communication over the preferred network interface in response to a determination that the preferred network interface does have connectivity. The controller directs communication over an alternate one of the network interfaces in response to a determination that the preferred network interface does not have connectivity.

A power supply system comprises a portable first power supply device and second power supply device. The portable first power supply device has a handle to be gripped by a hand of a user. A supply unit of the portable first power supply comprises an inverter circuit which converts at least a portion of excess power into an alternating current, and supplies to the second power supply device via a second connection unit and a power line, power of the alternating current outputted from the inverter circuit.

A smart grid for improving the management of a power utility grid is provided. The smart grid as presently disclosed includes using sensors in various portions of the power utility grid, using communications and computing technology to upgrade an electric power grid so that it can operate more efficiently and reliably and support additional services to consumers. The smart grid may include distributed intelligence in the power utility grid (separate from the control center intelligence) including devices that generate data in different sections of the grid, analyze the generated data, and automatically modify the operation of a section of the power grid. Further, the intelligent devices in the power utility grid may cooperate together to analyze and/or control the state of the power grid. Finally, the distributed intelligence may further include distributed storage.

The present disclosure provides a computer-implemented method for prioritizing one or more instructional control strategies to reduce time-variant energy demand of a built environment associated with renewable energy sources. The computer-implemented method includes collection of a first set of statistical data, fetching of a second set of statistical data, accumulation of a third set of statistical data, reception of a fourth set of statistical data and gathering of fifth set of statistical data. Further, the computer-implemented method includes parsing and comparison of the first set of statistical data, the second set of statistical data, the third set of statistical data, the fourth set of statistical data and the fifth set of statistical data. In addition, the computer-implemented method includes identification and prioritization of one or more instructional control strategies to reduce the time-variant energy demand associated with the built environment.

Described herein are methods for determining, based on actual crank conditions, an ability of a battery connected to an electric starter motor, to start an internal combustion engine, wherein the battery is a single monobloc or a plurality of monoblocs that are electrically connected in series or parallel. The method may include: receiving battery temperature data, representing a temperature of the battery at a time of cranking the internal combustion engine; receiving voltage data monitored from the battery, determining an instantaneous minimum voltage of the battery during the time of cranking the internal combustion engine; and determining a capability of the battery to crank the internal combustion engine based on the battery temperature data and the instantaneous minimum voltage of the battery.

The system may be configured to perform operations including measuring a temperature and a voltage of a battery at various times producing data points, wherein each data point comprises the temperature and voltage of the battery and a respective time that the temperature and voltage was measured; assigning each data point to a respective cell in a matrix stored on a, wherein the matrix comprises a first axis comprising voltage ranges and a second axis comprising temperature ranges, wherein each cell is associated with a voltage range and a temperature range, wherein the voltage and temperature of each data point is within the voltage range and temperature range, respectively, of the respective cell; and/or generating a first value in a counter comprised in each cell reflecting a total number of data points assigned to the cell, such that the first value in each cell is stored in the memory.

Methods and systems for performing network reconfigurations for networks including one or more renewable energy devices are described herein. In one exemplary embodiment, a network reconfiguration engine is used to determine an energy level of one or more renewable energy devices within the network. The reconfiguration engine is then capable of determining an optimal path for the network reconfiguration such that a least portion of the network's load is impacted, as well as a minimal number of switching operations are needed. The optimal path also, in one embodiment, includes performing a resiliency estimation for the post-network reconfiguration topology. An updated relay setting for the post-network reconfiguration topology is determined, and a status of any other engines associated with the reconfiguration is determined, after which the network reconfiguration is performed.
