摘要： Methods of powering a radio that is mounted on a tower of a cellular base station are provided in which a direct current (“DC”) power signal is provided to the radio over a power cable and a voltage level of the output of the power supply is adjusted so as to provide a substantially constant voltage at a first end of the power cable that is remote from the power supply. Related cellular base stations and programmable power supplies are also provided.

摘要： In embodiments of the present disclosure, after a mobile terminal recognizes a type of a power adapter, the mobile terminal transmits indication information to the power adapter. The indication information is configured to indicate that the mobile terminal has recognized the type of the power adapter and instruct the power adapter to activate a quick charging process. The power adapter then negotiates with the mobile terminal via the quick charging process to determine charging parameters, and charges a battery of the mobile terminal in a multi-stage constant current mode.

摘要： A power distributor for a communications system for controlling delivery of electrical power drawn over a plurality of electrical communications connections allocated to respective customer premises equipment, to provide electrical power to network components within a network is arranged to control collection of electrical power to be drawn from each connection in accordance with power requirements of services operated by or for its respective customer premises equipment, independent of the identities of the electrical connections used to deliver those services. In particular when electrical connections are not being used by their respective customers they may instead be used by a beam-forming system to support improved service to a customer associated with a different connection, and the additional electrical power to power the beam-former is drawn from the connection associated with the customer receiving the enhanced service.

摘要： The present subject matter relates to one or more devices, systems and/or methods for generating sealing current at a customer's premises or residence and injecting the sealing current into a DSL service provider's telephone cables to prevent the oxidation or corrosion of wire splices or connections on the telephone cables transporting DSL services. A cable pair stabilizer unit is connected at the customer's premises or residence, between the service provider's telephone cables and the customer's residential gateway/modem. The cable pair stabilizer unit comprises circuitry for generating the sealing current and for injecting the sealing current into the service provider's telephone cables transporting DSL services. The cable pair stabilizer unit may be combined with an AC/DC power supply adapter as a single, integrated device. The cable pair stabilizer unit may alternatively be combined with or inside of the Residential Gateway as a single, integrated device.

摘要： A power transmission system includes a voltage measurement device located on a tower or rooftop for measuring a voltage (VRRH) at a top end of a DC cable connected to a remote radio head (RRH). A voltage control system receives an input voltage (VIN) from a DC power supply and generates an output voltage (VOUT) at a base end of the DC cable. The voltage control system calculates a voltage drop on the DC cable based on the VRRH measurement and then adds different voltage steps to VIN so VOUT compensates for the voltage drop. Calculating the voltage drop allows the PTS to more efficiently supply power to RRHs without having to increase the size of DC power cables.

摘要： This application relates to monitoring of electronic devices (100) and in particular to methods and apparatus for the detection and recording of an electrical overstress applied to a connector (101, 102) of the device. The apparatus describes an integrated circuit integrated circuit (103, 105) of the host device having a first set of one or more circuit contacts (201, 203, 204, 205) for connection to a connector (101) of a host electronic device. The circuit has an electrical overstress monitor (106, 106a) for detecting and recording an electrical overstress comprising a voltage exceeding a predetermined parameter applied to at least one of said first set of circuit contacts. The electrical overstress monitor (106) may have an overvoltage detector (205) and may have a memory (206) for recording the occurrence of an overvoltage and/or a communication module (207) for communicating with other components of the host device in the event of an electrical overstress.
