Patent number: 9887538Abstract: The invention relates to a DC power distribution system for distributing DC power from a power supply device (3) to an electrical device (2). The power supply device is operable in a high power mode or in a low power mode for supplying a higher power or a lower power, respectively, to the electrical device via an electrical conductor (4), wherein the electrical device is switchable between a high power mode and a low power mode in which the electrical device consumes more power or less power, respectively. An electrical device control unit (11) controls the mode of the electrical device depending on the power supplied by the power supply device. This automatic control of the electrical device depending on the provided power can lead to a better balance between the power consumption and the power supply and, thus, to an improved efficiency of supplying power to the electrical device.Type: GrantFiled: August 6, 2013Date of Patent: February 6, 2018Assignee: PHILIPS LIGHTING HOLDING B.V.Inventors: Matthias Wendt, Michael Alex Van Hartskamp, Maurice Herman Johan Draaijer, Manuel Eduardo Alarcon-Rivero, Bozena Erdmann

Publication number: 20150200540Abstract: The invention relates to a DC power distribution system for distributing DC power to one or several electrical devices. The system comprises an electrical device (2) for receiving DC power via an electrical conductor (4) from a power supply device (3) with a power supply control unit (5) and for transmitting a signal to the power supply control unit for requesting a lower power or a higher power. The power supply device is operable in a high power mode and in a low power mode, wherein the power supply control unit controls the power mode of the power supply device depending on the received signal. This allows adapting the power supply to the power, which is actually really needed in the DC power distribution system, in a technically relatively simple way. Particularly standby situations can be handled more efficiently.Type: ApplicationFiled: August 9, 2013Publication date: July 16, 2015Inventors: Maurice Herman Johan Draaijer, Matthias Wendt, Michael Alex Van Hartskamp, Bozena Erdmann, Manuel Eduardo Alarcon-Rivero

Patent number: 8964546Abstract: Systems and methods are disclosed herein for measuring the traffic flow on a link. The system includes a processor that is configured to generate aggregate egress data for multiple origin endpoints by aggregating amounts of egress traffic detected by servers processing the egress traffic at the origin endpoints. The processor is also configured to obtain the proportions of traffic flows that traverse each path between each endpoint pair, which includes an origin endpoint and a destination endpoint. Each path includes multiple network links such that a single network link may be shared across multiple paths. Finally, the processor computes an amount of traffic flow on a shared link based on the aggregate egress data and the obtained proportions.Type: GrantFiled: January 31, 2013Date of Patent: February 24, 2015Assignee: Google Inc.Inventors: Sushant Jain, Alok Kumar, Rui Zhang-Shen, Michael Alex Frumkin, Aspi Homi Siganporia, Matthew Jonathan Holliman

Publication number: 20140361620Abstract: The invention relates to an overload detection device (1) for detecting an overload condition in a DC system (5) comprising a DC voltage source (4) and several electrical devices (8, 9, 10) electrically connected to the DC voltage source. The overload detection device comprises an overload detection unit for detecting the overload condition and a reducing unit for reducing the power consumed by an electrical device of the several electrical devices, if the overload detection unit detects the overload condition. Since the overload detection device reduces the power consumed by an electrical device of the several electrical devices, if the overload detection unit detects the overload condition, the overload condition may be removed, without requiring manual intervention. This allows for an improved recovery of the DC system.Type: ApplicationFiled: December 20, 2012Publication date: December 11, 2014Inventors: Michael Alex Van Hartskamp, Manuel Eduardo Alarcon-Rivero, Matthias Wendt, Bozena Erdmann, Maurice Herman Johan Draaijer
