A modular in vitro diagnostics (IVD) vessel mover system providing redundant power management includes a plurality of modules which are configured to provide storage to one or more IVD samples. Each module comprising a power failover switch which is configured to receive internal power from an internal primary power source and transmit backup power to one or more of the plurality of modules.

Methods and systems are disclosed for leveraging user premises supplied electric power to power active components in an information delivery network. In response to one or more conditions, an active component may switch an input power path from using grid-supplied or battery power to draw power from a user premises. The decision to switch the power path may be based on a number of conditions, for example, whether power is available from the grid, the relative cost of power from the user premises and whether the power from the user premises includes power from a renewable source.

Provided are a load transfer method and system in thunder and lightning weather. The method includes: detecting lightning and predicting a position and time of a lightning strike to obtain a lightning prediction result; determining a transmission line possibly struck by lightning in a power grid according to the lightning prediction result; determining a load transfer scheme; and before the lightning occurs, transferring at least part of loads on the transmission line possibly struck by lightning according to the load transfer scheme.

An electrical load system includes one or more electrical loads, a power transfer switch, and an electronic control system. The power transfer switch is coupled with and can provide power to one or more electrical loads from a first power source or a second power source. The electronic control system evaluates a source impedance of the first source and controls the power transfer switch in response to the source impedance of the first source indicating a fault condition of the first power source that would interrupt power from the first power source to the one or more electrical loads prior to the fault condition disrupting power from the first power source to the one or more electrical loads.

A wind turbine nacelle configured for mounting on a wind turbine tower and for supporting a rotor-supporting assembly, the nacelle comprising a main unit, and at least one auxiliary unit. The auxiliary unit accommodates at least one operative component, e.g. a converter, a transformer, an electrolysis cell, or a battery. An operative component having a similar function is accommodated in another auxiliary unit which thereby facilitate shared operation, and easy and fast maintenance or replacement of the operative component.

A changeover device for selectively supplying power to at least one load from a grid or a bidirectional inverter includes an input having a grid neutral conductor connection and a grid phase conductor connection for connection to the grid. The changeover device further includes a first output having an inverter neutral conductor connection and an inverter phase conductor connection for connecting the bidirectional inverter, a second output having a load neutral conductor connection and a load phase conductor connection for connecting the load and a switching circuit, the actuator of which is connected to an actuator input of the changeover device. The switching circuit includes a first and a second normally closed contact and a normally open contact that are connected in an interconnection to the grid phase conductor connection, the inverter phase conductor connection, and the load phase conductor connection. An associated method is also disclosed.

Embodiments for power generation include defining a power tile within a power distribution network having a grid of power rails, the power tile having logic gates, and applying an initial power grid pattern from a plurality of power grid patterns for the power tile such that initial power grid pattern relates to timing characteristics of the logic gates of the power tile. The power grid patterns each have a different number of connectors connecting one power rail to another power rail in the grid of power rails. A subsequent power grid pattern is selected from the power grid patterns for the power tile such that the subsequent power grid pattern meets a threshold condition for the timing characteristics of the logic gates of the power tile. The timing characteristics for the logic gates are determined based on a voltage drop associated with the subsequent power grid pattern.

A control system and method for a group of interconnected feeders which enables fault location, isolation and service restoration without requiring each switch to have topology knowledge of devices in adjacent feeders. The method defines, for each switch, connectivity and X/Y directional information about its neighboring switches and propagates this information throughout each feeder. A leader device is also determined for each feeder. Information about topology of adjacent feeders is not needed by all devices. Only normally-open tie switches which define a boundary between two adjacent feeders have knowledge of the devices in both feeders. Switches which open during fault isolation automatically find open tie switches in a direction opposite the fault, and request service restoration downstream of the fault by providing power from an adjacent feeder. Leader devices ensure an overload condition is not created before initiating opening and closing operations of switches downstream of the fault.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for using a neural network to predict locations of feeders in an electrical power grid. One of the methods includes training a generative adversarial network comprising a generator and a discriminator; and generating, by the generator, from input images, output images with feeder metadata that represents predicted locations of feeder assets, including receiving by the generator a first input image and generating by the generator a corresponding first output image with first feeder data that identifies one or more feeder assets and their respective locations, wherein the one or more feeder assets had not been identified in any input to the generator.
