One exemplary embodiment is a method for removing false data in a nested microgrid system, the method comprising: calculating a first local state estimation using a first plurality of local measurements and a second local state estimation using a second plurality of local measurements; calculating, with a central control system, a plurality of global state estimations including a first global state estimation a second global state estimation; performing a first false data detection test using the first local state estimation and one global state estimation of the plurality of global state estimations; performing a second false data detection test using the first global state estimation and the second global state estimation; detecting false data; and updating the first global state estimation, the second global state estimation, or the first local state estimation in response to detecting the false data.

Disclosed is a method including receiving, from an application or function, information indicating at least one of: one or more actions performed or predicted to be performed by the application or function, or one or more key performance indicators indicating an impact or predicted impact of the one or more actions, the one or more actions causing a change in at least one of: communication traffic associated with the one or more base stations, or power consumption of the one or more base stations or one or more subcomponents of the one or more base stations; determine, based at least partly on the received information, one or more virtual power plant actions or one or more peak shaving actions associated with at least one base station; and initiate the one or more virtual power plant actions or the one or more peak shaving actions.

A battery management apparatus and a communication method thereof in a battery rack system according to an embodiments of the present invention may wake up in response to power supplied from a battery management apparatus of the battery rack through the first electromagnetic induction coil, receive information about an identifier of the first battery pack from the battery management apparatus of the battery rack through the wireless communication module, allocate an identifier to the first battery pack based on the information about the identifier of the first battery pack, and supply power to a second battery pack located near the first battery pack through the second electromagnetic induction coil, thereby providing a battery management apparatus and a communication method without a communication cable.

A vehicle includes an internal cabin, and a system for wirelessly transmitting electrical signals between a first component and a second component within the internal cabin. The system includes a first circuit including a first coil secured to the first component. The first coil is electrically connected to one or both of a power source or a data source onboard the vehicle. A second circuit includes a second coil secured to the second component. The second coil is electrically connected to an electrical device secured to the second component. The first circuit is separated from the second circuit by a gap. The first coil is configured to receive one or more electrical signals from the power source and/or the data source. The electrical signals are induced in the second circuit by the first circuit and transmitted to the electrical device.

A method includes the steps of obtaining distance measurements between a device and a number of lighting fixtures, processing the distance measurements to assign coordinates to each one of the lighting fixtures, and facilitating registration of the coordinates of a subset of the lighting fixtures to obtain registered coordinates for all of the lighting fixtures. The coordinates indicate a relative location of each one of the lighting fixtures with respect to one another. The registered coordinates indicate a location of each lighting fixture in a desired coordinate space. Accordingly, a location of a lighting fixture within a desired coordinate space can be easily obtained, which may enable significant additional functionality of the lighting fixture.

A method of controlling an electronic apparatus includes supplying power to a second controller, receiving an activation time for supplying power to a communication portion and a deactivation time for interrupting power to the communication portion, setting time information based on the activation time and the deactivation time, performing, based on the time information, a standby step that includes interrupting power to a first controller, a first load portion, and the communication portion while supplying power to the second controller, controlling the communication portion switch to supply power to the communication portion based on the activation time, determining whether the communication portion has received the control command from the remote control terminal, and interrupting the power supplied to the communication portion and re-executing the standby step based on determining that the communication portion has not received the control command from the remote control terminal.

Generally, this disclosure relates to methods of prioritizing or directing available power to a main device, such as a temperature-stabilized and/or temperature-controlled storage container. In an embodiment, the method may include measuring electrical power available from a solar photovoltaic module array that is electrically coupled to the main device, and modulating the electrical power drawn by the main device based on the available electrical power. Available power unused by the main device may be diverted to one or more secondary devices.

An information processing apparatus includes: a detector that detects a voltage of a power system to which the information processing apparatus itself is connected, from among a plurality of power systems to which are respectively connected a plurality of electrical devices respectively available for communication; a receiver that receives running information expressing running conditions of each of the plurality of electrical devices; and a reporting unit that uses a detection result of the detector and a reception result of the receiver to report whether or not an electrical device corresponding to the running information received by the receiver is connected to the power system to which the information processing apparatus itself is connected.

Aspects of the subject disclosure may include, for example, a transmission system having a coupling device, a bypass circuit, a memory and a processor. The coupling device can facilitate transmission or reception of electromagnetic waves that propagate along a surface of a transmission medium. The memory can store instructions, which when executed by the processor, causes the processor to perform operations including restarting a timer to prevent the bypass circuit from disabling the transmission or reception of electromagnetic waves by the coupling device. Other embodiments are disclosed.

A customer vehicle management system includes fob devices that each include a customer portion and a key portion, that are separable and may be magnetically interlocked with a charging and communication link between them. The system provides dynamic association of fob customer portions, fob key portions and docking units housed within a cabinet. Customer portions are deployed to a customer (driver) who may later request retrieval of a vehicle the keys of which were left with an operator (valet). Vehicle requests are made through a wireless link. A communications and management module within a fob and key storage cabinet receives the request signal and activates an indicator on a docking unit associated with the customer portion and where an associated key portion is docked. The operator may then retrieve vehicle keys associated with the customer portion from which the request was made.
