摘要： Methods and systems for providing intelligent power distribution. A distribution point unit is connected to a plurality of user units in a telecommunications system. A loss of power to the distribution point unit is detected. It is determined that at least one user unit has backup power. Based on a determination that at least one user unit has backup power, a power mode for the distribution point unit is selected. The power mode is implemented on the distribution point unit.

摘要： The present invention relates to an apparatus and a method for load balancing among multi-ports in reverse power feeding, and more particularly, to an apparatus and a method which, in the process in which a distribution apparatus performs load balancing among multi-ports by reversely receiving power from multiple customer premises at a distribution point, when reverse power feeding from a specific customer premise is stopped, since a power burden of a remaining customer premise is increased, which interfere with a communication service, can reduce power consumption on the distribution by releasing a link of a communication port connected with the corresponding customer premise as soon as the power feeding is stopped and provide a stable communication service by performing the load balancing only with respect to remaining communication ports.

摘要： A system for powering a network element of a fiber optic wide area network is disclosed. When communication data is transferred between a central office (CO) and a subscriber terminal using a network element to convert optical to electrical (O-E) and electrical to optical (E-O) signals between a fiber from the central office and twisted wire pair, coaxial cable or Ethernet cable transmission lines from the subscriber terminal, techniques related to local powering of a network element or drop site by the subscriber terminal or subscriber premise remote powering device are provided. Certain advantages and/or benefits are achieved using the present invention, such as freedom from any requirement for additional meter installations or meter connection charges and does not require a separate power network.

摘要： The present disclosure provides a fast charging method, a power adapter, and a mobile terminal. The method includes: transmitting, by the power adapter, a clock signal to the mobile terminal via a first data line of a USB interface in a process of coupling the power adapter with the mobile terminal, where the clock signal is configured for indicating a communication sequence between the power adapter and the mobile terminal; conducting, by the power adapter, a bidirectional communication with the mobile terminal via a second data line of the USB interface under control of the communication sequence, so as to determine to charge the mobile terminal in a fast charging mode; and adjusting, by the power adapter, a charging current to be a charging current of the fast charging mode to charge the mobile terminal.

摘要： An electronic system may include a charging device and an electronic device. The charging device may include an input port, a charge circuit, a storage, and a connector device. The charging device may receive a direct current (DC) voltage at the input port. The charge circuit may receive the DC voltage and provide a charged voltage to the storage. The electronic device may include a body, a battery, a first pad directly on the battery and a second pad directly on the battery. The battery may receive the DC charged voltage when the electronic device is coupled to the charging device.

摘要： A synchronous audio playback method, apparatus and system are provided. The method includes calculating a first playback delay generated when an audio file is played; acquiring a second playback delay; calculating a delay offset; calculating a data adjustment amount; adding to-be-adjusted data to or deleting to-be-adjusted data from a current to-be-played part of the audio file according to a value of the delay offset, to obtain a replacement part corresponding to the current to-be-played part, where a data amount of the to-be-adjusted data is the data adjustment amount; and playing the replacement part. With the technical solutions of the present invention, playback duration of a current to-be-played part can be adjusted in a manner of adding or deleting data, so that a controlling device and a controlled device generate sounds simultaneously when playing a to-be-played clip in a very simple implementation process.
