The present invention relates to methods and apparatuses for managing the time slots in time division duplex (TDD) frames in an xDSL system. According to certain aspects, power savings in a TDD system operating with vectoring may be achieved with sending of quiet symbols in time slots that do not have data and through the efficient configuration of time slots with data and/or idle symbols so as to limit the amount of processing by the vectoring engine within the DO portion of each TDD frame. In embodiments, a central controller in a DPU monitors the data buffers at the transmitter input on each line and computes an optimal configuration of the time slots in the DO portion of the TDD frame to achieve an optimal balance between performance and power dissipation.

A the network-side distribution point in a telecommunications network includes an input measurement function which monitors the total power delivered to the power combiner from the various customer premises, and an output measurement function which monitors the total power requirements of the components of the distribution point. The data from these monitoring functions are used by a power extraction control unit to control the combiner/extraction unit to draw power from the forward power feed to makes up any shortfall in the power required to operate the components. This allows each customer premises system to deliver power to the distribution point at a rate determined only by the services it is itself using, and without any need for co-ordination between the distribution point and the customer premises systems.

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.

Power bank system. In one embodiment, a power bank system includes a docking station and a power bank configured to dock with the docking station such that the power bank is configured to provide electrical power to the docking station while the power bank is docked with the docking station.

Power management is provided in an Internet protocol (IP) telephone and system to provide energy savings during times that the IP telephone is not in use or use is not expected. A low-power operating mode disables at least a portion of the IP telephone. The low-power operating mode may be initiated by a command received by the IP telephone from the IP telephone controller according to a schedule, which may be modified locally by the user to individualize the user's schedule. The low-power operating mode may alternatively be activated manually by a user pressing a special key, sequence or combination. The low-power operating mode is canceled upon an indication that a user either is or should be present at the IP telephone.

In one embodiment, a portable power bank system may include a portable power bank and a software application. The portable power bank may include a power bank housing, one or more batteries internal to the power bank housing, and one or more electrical receptacles that are defined by the power bank housing. Each of the one or more electrical receptacles may be configured to selectively provide electrical power from the one or more batteries. The software application may include one or more computer-readable instructions that are configured, when executed by one or more processors of a portable computing device, to cause the portable computing device to communicate with the portable power bank over a wireless network to receive information regarding a current state of the portable power bank and to present the current state of the portable power bank on the portable computing device.
