  • Patent number: 10055384
    Abstract: Techniques disclosed herein decouple a document's structure from its general content wherein the structure is retained in plaintext (both at a client device and in a server system) and the data is retained in cyphertext, and where the cloud-based server system is not tasked with the saving or management of the relevant cryptographic keys. Because the network- or cloud-based server system has “zero-knowledge” about the document's data content or the relevant cryptographic keys, an attack on the server system does not put the security of the document's data at risk. In addition, the network- or cloud-based server system may be used to perform the computationally intensive tasks of converting the document between a first format (often associated with a full-function document processing application not supported by the client device) and a second format (easily displayed and manipulated by a client device).

  • Publication number: 20140266141
    Abstract: Systems and methods for digital voltage compensation in a power supply integrated circuit are provided. In at least one embodiment, a method comprises receiving a digital voltage code, the digital voltage code corresponding to an output voltage value; setting an output count on a first counter to change from a present first digital count corresponding to a present voltage code value toward a target first digital count corresponding to a new voltage code value; and setting a second count to an offset count value on a second counter when the new voltage code value is received. The method also comprises combining the second count with the output count to form a combined count value; and decrementing the second count value from the offset count value to zero when the first counter reaches the target first digital count.

  • Patent number: 8805552
    Abstract: A client device manages consumption of power supplied by an electric utility to multiple power consuming devices. Power flow to the power consuming devices is selectively enabled and disabled by one or more controllable devices controlled by the client device. The client device receives a power control message from a load management server. In one embodiment, the power control message indicates at least one of an amount of electric power to be reduced and an identification of at least one controllable device to be instructed to disable a flow of electric power to one or more associated power consuming devices. Responsive to the power control message, the client device issues a power management command or instruction to one or more controllable devices under the client device's control. The power management command causes the controllable device(s) to disable a flow of electric power to at least one associated power consuming device.

  • Patent number: 8796973
    Abstract: In a multi-phase brushless DC motor, a zero crossing N-bit filter includes a comparator and a phase multiplexer. The phase multiplexer connects each motor phase to each of a positive and a negative input of the comparator, with a switch in each connection to form a switch array. A microprocessor is disposed to operate the switches, and is configured to measure a BEMF for a first phase by opening the switches connecting all other phases to the positive input of the comparator and by opening the switch connecting the first phase being measured to the negative input of said comparator. The comparators output is received by a shift register. The microprocessor is configured to respond to a zero crossing when a majority of bits in the shift register change between high and low.

  • Patent number: 8775846
    Abstract: A portable DC power manager (400) includes an internal power bus (410) and a plurality of device ports (1150, 1160, 1170, 1180, 1190, 1200) for connecting with external power and energy sources, external power loads and other external power managers. Each device port is isolated for the internal power bus by controllable switches (A, B, C, D). Power converters (440, 442, 510) may be disposed between device ports and the internal power bus to convert voltages and attenuate current amplitude. Energy management schema operating on the power manager sums available power and allocates the available power to connected power loads according to power priority settings. A hot-change-over circuit (1300) connects additional sources to the internal bus in response to a voltage drop on the internal power bus. A compact and lightweight package (1100) enables a portability.
