  • Publication number: 20150021995
    Abstract: Methods and apparatus for dynamically adjusting the amount of power (or current) distributed to one or more connected devices via electrical interfaces. In one embodiment, the apparatus comprises a first module adapted to detect current drawn by a first set of ports, and a second module adapted to adjust the current provided to a second set of ports based on the detected current. The second module is also optionally adapted to distribute unreserved current among the devices according to an allocation protocol. In the exemplary context of a plurality of interconnected serial bus devices, the invention enables a device to draw more current than that required to be reserved for that device (such as to comply with a specification such as USB), yet without increasing the total amount of power which must be dedicated to the serial ports as a whole. Power supply efficiency may also be advantageously optimized.

  • Patent number: 7706299
    Abstract: A technique for estimating the upstream bandwidth for a modem is provided. Various-sized packets are sent on roundtrip journeys through the modem. The roundtrip times for the various-sized packets are compared to provide an estimate of the modem's upstream bandwidth. Alternatively, a block file may be transmitted through the modem to a TFTP server. The TFTP server reports the time needed to complete the file transfer. Based upon the block file transmission start time and the completion time, an upstream bandwidth estimate may be performed. Given the upstream bandwidth estimation, non-VoIP upstream data traffic may be limited accordingly to provide a desired QoS to VoIP calls being supported by the modem.
