Abstract: A circuit breaker includes an electromechanical switch, a current sensor, a voltage sensor, and a processor. The electromechanical switch is serially connected between a line input terminal and a load output terminal of the circuit breaker, and configured to be placed in a switched-closed state or a switched-open state. The current sensor is configured to sense a magnitude of current flowing in a 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 at a point on the path between the line input and load output terminals and generate a voltage sense signal. The processor is configured to receive and process the current sense signal and the voltage sense signal to determine operational status information of the circuit breaker and determine power usage information of a load connected to the load output terminal.

Abstract: Systems and methods are provided for intelligent energy source monitoring and selection control to enable power delivery in a multi-modal energy system. A multi-modal energy system includes a control system, power supply systems, and an electrical distribution system. The power supply systems are coupled to the control system. The power supply systems include a mains utility power system and at least one renewable power system. The electrical power distribution system is coupled to the control system. The control system is configured to monitor each power supply system to determine a power availability of each power supply system, determine an amount of power usage by the electrical power distribution system, and selectively connect and disconnect one or more of the power supply systems to the electrical power distribution system based on the determined power availability of the power supply systems and the determined power usage of the electrical power distribution system.

Abstract: 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.

Abstract: An apparatus comprises at least one processing device comprising a processor coupled to a memory. The processing device is configured to receive from a requester a request to modify a parameter of an access-controlled account associated with a set of sensor devices. Responsive to receipt of the request, the processing device initiates at least one instance of a proof of physical presence protocol, the proof of physical presence protocol requiring performance by the requester of at least one action involving at least one sensor device of the set of sensor devices associated with the access-controlled account. Responsive to successful completion of at least one instance of the proof of physical presence protocol, the processing device sends at least one notification to each of one or more registered users of the access-controlled account. The processing device approves or rejects the request based at least in part on at least one of a number and a type of responses to the one or more notifications.

Abstract: An apparatus in an illustrative embodiment comprises at least one processing device comprising a processor coupled to a memory. The processing device is configured to receive sensor data from one or more nodes of a node network, to compute predicate data based at least in part on the received sensor data, to transmit at least a portion of the received sensor data and the computed predicate data to a third party application, to receive additional data from the third party application responsive to the transmitted portion of the received sensor data and the computed predicate data, to generate a control signal based at least in part on the received sensor data, the computed predicate data, and the received additional data from the third party application, and to transmit the control signal to at least one of the nodes of the node network. Other illustrative embodiments include methods and computer program products.
