The testing device may further include at least one of an LCD screen or a light-emitting diode (“LED”) light. At least one of the LCD screen or the LED light may display at least one randomly generated visible identification indicia.

A power control system with a power management apparatus and a power monitoring control apparatus for each control segment. The power monitoring control apparatus is provided with: a contribution degree setting unit setting the degree of contribution of each control segment; a device control unit controlling the power consumption of each power using device connected; a priority control unit setting a priority for reducing the power of the power using device; and a device monitoring unit obtaining the priority of each power using device and transmitting the obtained priority to the power management apparatus. The power management apparatus is provided with an optimum control calculation unit determining a control command for controlling each power using device connected. The control command is determined based on: a target value of the total power consumption of all the control segments; the degree of contribution; and the priority of each power using device.

An EPF digital record transmission system may be configured to transmit an EPF digital record from an EPF device to a user device. The user device may then transmit the EPF digital record to a host server for storage and processing. The EPF device may also be configured to transmit health data and the user device may be configured to analyze one or both of the health data and the EPF digital record and present a health recommendation.

An apparatus for connecting a wireless sensor may include a charging battery which is self-powered, a measurement sensor configured for performing wireless communication and receive power from the charging battery, and a vehicle controller configured to be connected to the measurement sensor through wireless communication and receive measured data.

Power models may be used to identify devices in a building or state changes of devices in a building by processing a power monitoring signal with the power models. A power model for a device may be trained using examples of power monitoring signals corresponding to that device, and network monitoring may be used to identify training data for training power models for that device. Network monitoring may include receiving information about network packets transmitted by devices in the building and processing the information about the network packets to determine information about a state change of a first device in the building at a first time. A portion of the power monitoring signal that includes the first time may then be used to train a power model for the first device. The trained power model for the first device may then be deployed to a building where it used to perform power monitoring of the first device.

Embodiments described herein include an acoustic telemetry system for use with an apparatus configured to rotate. The acoustic telemetry system includes one or more sensor nodes and at least one receiver node. In at least one embodiment, the telemetry system also includes at least one hub node positioned on the apparatus. Each sensor node is attached to or embedded in the apparatus. Each sensor node obtains data related to one or more operating conditions of the apparatus and the environment surrounding the apparatus. The one or more sensor nodes encode and transmit the data to the hub node or the receiver node using ultrasonic acoustic waves. In at least one embodiment, the hub node transmits the data to the receiver node. The receiver node decodes the data and monitors the one or more operating conditions of the apparatus.

Aspects include a water-leak-detection and -monitoring system for a building including a first area, comprising a memory, a communication interface configured to be communicatively coupled to a water-flow sensor coupled to a pipe in the first area, at least one of a humidity sensor, a temperature sensor, or a liquid-water sensor configured to sense information indicative of a presence of water in the first area, and an analytical engine in communication with a base unit, the memory, the communication interface, and the at least one of the humidity sensor, the temperature sensor, or the liquid-water sensor, the analytical engine being configured to determine whether a leak is present in the building based on data from the water-flow sensor, and determine, responsive to determining that the leak is present, if the leak is in the first area based on the information indicative of the presence of water in the first area.

A data receiver receives at least one signal from a data transmitter and determines therefrom at least one environment parameter of the data transmitter or of an environment of the data transmitter. The data receiver is configured to identify an operational state of the data transmitter or of a component of the data transmitter by comparing the at least one environment parameter so received or an environment parameter profile determined on the basis of the at least one environment parameter, with an environment parameter reference profile which describes an expected environment parameter or an expected environment parameter profile in the environment of the data transmitter.

A battery sensor data transmission unit is described as including a connection state ascertainment unit for ascertaining a series connection state in which a battery cell is connected in series to one other battery cell with the aid of a power transmission line and/or for determining a bypassing state in which at least one pole of the battery cell is decoupled from at least one other battery cell. Furthermore, the battery sensor data transmission unit includes a data transmission unit designed for outputting a sensor signal, which represents a physical variable in or at the battery cell, in the series connection state to an evaluation device using the power transmission line and/or outputting the sensor signal in the bypassing state to the evaluation device using a battery housing wall as the transmission medium.
