A device for transmitting data between a data transmission device of a vehicle and a data transmission device of a communications network, as part of a charging process of an electrical energy store of the vehicle, is disclosed. The vehicle data transmission device is based on a first communications protocol with a first signal level, while the communications network data transmission device is based on a second communications protocol with a second signal level. The device includes a signal-matching device having at least one first coupling transformer, which couples a data transmission device of a charging station to the data transmission devices of the vehicle and of the communications network via respective coils. The signal-matching device is configured to match the first signal level to the second signal level and vice versa.

Aspects of the subject disclosure may include, for example, a device that facilitates transmitting electromagnetic waves along a surface of a wire that facilitates delivery of electric energy to devices, and sensing a condition that is adverse to the electromagnetic waves propagating along the surface of the wire. Other embodiments are disclosed.

Representative implementations of devices and techniques provide an efficient communication that enables nodes in a reduced power consumption state to resume a regular power state (e.g., fully operational) or otherwise another power state (e.g., semi-operational) after processing the communication.

This application relates generally to the field of network communications and, more particularly, to transmitting data over power lines.

Methods, systems, and computer program products for generating high resolution inferences in electrical networks are provided herein. A computer-implemented method includes collecting multiple items of data from one or more data sources arising from a power distribution network, wherein the multiple items of data comprise (i) one or more levels of temporal resolution and (ii) one or more levels of spatial resolution; determining a network topology of the power distribution network based on identification of one or more connections between each of multiple components within the power distribution network; and generating a power flow estimate for one or more nodes within the power distribution network at a pre-determined level of spatio-temporal resolution, wherein said generating comprises applying a model to (i) the multiple items of collected data, (ii) the determined network topology, and (iii) one or more relations constraining the power flow estimate at the pre-determined level of spatio-temporal resolution.

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for communication time slot allocation in a communication network. In one aspect, a first network device may determine that a second network device will transmit one or more packets associated with a first latency, and determine that a third network device will transmit one or more packets associated with a second latency. The first network device may determine to allocate a greater quantity of communication time slots to the second network device than to the third network device based, at least in part, on the first latency being less than the second latency. The first network device may allocate a first plurality of communication time slots of a beacon period to the second network device, and allocate a second plurality of communication time slots of the beacon period to the third network device.

Aspects of the subject disclosure may include, for example, a device that facilitates transmitting electromagnetic waves along a surface of a wire that facilitates delivery of electric energy to devices, and sensing a condition that is adverse to the electromagnetic waves propagating along the surface of the wire. Other embodiments are disclosed.

A method is for processing a channel analog signal coming from a transmission channel. The method may include converting the channel analog signal into a channel digital signal, and detecting a state of the transmission channel based on the channel digital signal to detect whether the transmission channel is, over an interval of time, one or more of linear and time invariant and linear and cyclostationary.

Aspects of the subject disclosure may include, for example, a device that facilitates transmitting electromagnetic waves along a surface of a wire that facilitates delivery of electric energy to devices, and sensing a condition that is adverse to the electromagnetic waves propagating along the surface of the wire. Other embodiments are disclosed.
