Sampled measurement data stream is controlled in an electrical network by measuring at least one measurement value in a remote device; detecting in the remote device at least one phenomenon of interest or request for connection from the central device; activating by the remote device a communication channel for sampled measured values between the remote device and a central device in response to the detection of the phenomenon of interest or the request for a connection from the central device; and sending the measurement value from the remote device to the central device through the communication channel for sampled measured values.

A distributed ledger based utility system architecture may be configured to enable secure payments, data transmission, and meter configuration of smart sensors. The utility system architecture may be a tiered architecture including multiple nodes at different levels of the architecture where each level may contain a different portion of the distributed ledger. As information is added to the distributed ledger, each portion of the distributed ledger may be updated based on whether the information is relevant to that node. The information may include rate contract transactions, meter configuration data transactions, payment transactions, or the like.

A system and method are described for implementing latched attributes within an IoT system. For example, one embodiment of a method comprises: specifying an attribute for each of a plurality of items of data managed in an Internet of Things (IoT) device and/or an IoT service, at least some of the attributes comprising latched attributes having a current value and an indication of state changes to the latched attribute over a period of time; when an IoT device is unable to connect with the IoT service for a period of time maintaining an indication of any state changes occurring to the latched attribute over the period of time; upon establishing a successful connection between the IoT device and the IoT service after the period of time, transmitting the indication of state changes of the latched attribute from the IoT device to the IoT service; and analyzing the indication of state changes to determine whether to generate an alert condition on the IoT service.

The disclosure relates to a meter for monitoring usage of power provided by a power transmission system to a site. The meter comprises: a communication module to generate communications carried over the transmission system; a relay having a first position connecting power from the transmission system to the site and a second position disconnecting power; a request manager module to process messages from a head end associated with the transmission system; a meter module connected to a power feed associated with the transmission system to provide readings relating to the power used at the site; an event manager module to evaluate new events queued in a message queue received by the meter and after evaluating the new events to send a message to the head end relating to the earliest event in the message queue; a connection manager module managing the power connection to the transmission system.

A data center energy management (DCEM) server configures a power supply in the data center. The DCEM server sums input alternating current (AC) power of the power supply to a total AC power of the data center, wherein the total AC power of the data center is a sum of AC power of a plurality of power supplies. The DCEM server sums output direct current (DC) power of the power supply to a total DC power of the data center and reports a ratio of total AC power to total DC power as data center power conversion efficiency. The DCEM server sets a preset power supply efficiency threshold. The DCEM server determines that a real-time power efficiency level is below the power supply efficiency threshold. The DCEM server, responsive to a determination that real-time power efficiency level is below the power supply efficiency threshold, may remedy the power supply.

Methods and Systems are described for control at/of a network node. The network node can include a control module and first and second modules coupled to the control module. The first module can be configured to select first input/output (I/O) types of a field device coupled at an I/O interface of the network node. The second module can be configured to select a second I/O types of the field device. The first and second modules can be coupled to the I/O interface through a field device coupler.

A method for constructing a modular surgical system is disclosed. The method comprises providing a header module comprising a first power backplane segment, providing a surgical module comprising a second power backplane segment, assembling the header module and the surgical module to electrically couple the first power backplane segment and the second power backplane segment to each other to form a power backplane, and applying power to the surgical module through the power backplane.

The present disclosure is directed at a method and apparatus for providing a network connected low voltage lighting system. In one embodiment, the disclosure may be seen as an Internet of Things (IoT) network connected low voltage lighting system.

Techniques are described for sharing data among Internet of Things (IoT) networks. An IoT network may include a platform that collects data generated by IoT devices. The platform may execute an agent that sends a communication to indicate the network presence of the sending platform to broker module(s) that support a data sharing service. The communication may also indicate the type and/or quantity of data generated by the sending platform and available to be shared with other receiving platforms in other IoT networks. The data broker module(s) may generate and send security tokens to the agents executing on the sending platform and receiving platform(s). Using the security tokens, the respective agents may establish a peer-to-peer (P2P) connection over a network over which the data is streamed in real time as it is received and/or processed by the sending platform.

In one implementation, a method for a solar cell array is provided, the method includes emitting a communication message from the solar cell array by reverse biasing the solar cell array so as to cause at least a portion of the solar array to emit a detectable amount of radiation corresponding to the communication message. In one embodiment a solar cell array circuit is provided including a solar string comprising a plurality of solar cells coupled together, a charge storage device coupled to a power bus, and a bidirectional boost-buck converter having a first and second pair of MOSFETs connected in series between positive and negative rails of the power bus with an inductor coupled from between the first and second paired MOSFETs to a charging output of the solar string.
