摘要： A power transmission device that wirelessly transmits power to a vehicle, the power transmission device including an information emitter that, in a case in which the position of the vehicle acquired by the information acquirer is located in a power transmission range of the power transmission coil and, also, the instruction receiver receives the instruction about power transmission, emits a first type of information that indicates a presence of the foreign object when the detector detects the foreign object, and in a case in which the instruction receiver does not receive the instruction about power transmission even though the position of the vehicle acquired by the position information acquirer is located in the power transmission range of the power transmission coil, does not emit the information that indicates the presence of the foreign object.

摘要： A portable power station (PPS) unit includes a controller that receives AC current information of AC input current at an AC input port and produces a control signal that is used to control the PPS unit to operate as a voltage source or a current source, and to control an AC output current at substantially the same magnitude, frequency, and phase as the AC input current. A PPS apparatus includes two or more PPS units connected together such that the AC output power of one PPS unit is connected to the AC input port of a next PPS unit; wherein a first PPS unit is a voltage source and each of the second or more PPS units is a current source, and a total AC output power of the PPS apparatus is substantially a sum of the AC output power produced by the two or more PPS units.

摘要： This disclosure provides systems, method, and computer-readable media for operating a sensor network. The sensor network can include an array of sensor devices and gateways. The sensor devices can sense various conditions of an environment. The sensor devices can include temperature sensors, occupancy detectors, access sensors, motion sensors, tracking devices, etc. The sensor devices can also network and communicate with one another and the gateways in an ad hoc or mesh network. The environment can include different locations, such as warehouse, office building, a complex of buildings, cargo vehicles, containers or the like. The sensor network can be deployed for controlling power consumption, logistics, automated manufacturing, healthcare, intelligent buildings, and smart cities among many other implementations. The sensor devices can communicate sensed conditions and transmit data among each other without a predefined route. When a gateway receives the data, the data can be stored and analyzed at a different location.

摘要： Systems, methods, and devices are provided for controlling part of an electric power distribution system using an intelligent electronic device that may rely on communication from wireless electrical measurement devices. Wireless electrical measurement devices associated with different phases of power on an electric power distribution system may send wireless messages containing electrical measurements for respective phases to an intelligent electronic device. When wireless communication with one of the wireless electrical measurement devices becomes inconsistent or lost, the intelligent electronic device may synthesize the electrical measurements of the missing phase using electrical measurements of remaining phases. The intelligent electronic device may use the synthesized electrical measurements to control part of the electric power distribution system.

摘要： A circuit breaker comprises a solid-state bidirectional switch, a switch control circuit, current and voltage sensors, and a processor. The solid-state bidirectional switch is connected between a line input terminal and a load output terminal of the circuit breaker, and configured to be placed in a switched-on state and a switched-off state. The switch control circuit control operation of the bidirectional switch. The current sensor is configured to sense a magnitude of current flowing in an electrical path between the line input and load output terminals and generate a current sense signal. The voltage sensor is configured to sense a magnitude of voltage on the electrical path and generate a voltage sense signal. The processor is configured to process the current and voltage sense signals to determine operational status information of the circuit breaker, a fault event, and power usage information of a load connected to the load output terminal.
