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).

  • Patent number: 8890505
    Abstract: A method for generating a value for available operating reserve for electric utility. Electric power consumption by at least one device is determined during at least one period of time to produce power consumption data, stored in a repository. Prior to a control event for power reduction and under an assumption that it is not to occur, power consumption behavior expected of the device(s) is determined for a time period during which the control event is expected to occur based on stored power consumption data. Additionally, prior to the control event, projected energy savings resulting from the control event, and associated with a power supply value (PSV) are determined based on devices' power consumption behavior. Amount of available operating reserve is determined based on projected energy savings.

  • Publication number: 20140333281
    Abstract: A method and device are disclosed for estimating a power demand level of an active circuit on a power supply line. A ripple amplitude and a ripple frequency associated with operation of the active circuit may be monitored on the power supply line. The ripple amplitude and ripple frequency may be compared with corresponding references. The ripple amplitude and ripple frequency may be associated with an estimated power demand level of the active circuit on the power supply line based on the comparison. A ripple generator generates a controlled ripple on the power supply line for calibration.

    Abstract: A power converter 1 includes: a DC/DC unit 2 converting DC voltage supplied from an electric vehicle V to a first DC voltage for a home 20 or a second DC voltage for an electric appliance 24; a first power line L1 outputting the first DC voltage; a second power line L2 outputting the second DC voltage; a relay 3; an external connector 4 to which the electric appliance 24 is connected; and a controller 5 controlling the DC/DC unit and relay 3. During regular operation, the controller 5 causes the DC/DC unit 2 to convert the DC voltage to the first DC voltage and brings the relay 3 into a disconnected state to supply the first DC voltage via the first power line L1. When the first power line L1 is offline, the controller 5 causes the DC/DC unit 2 to convert the DC voltage to the second DC voltage and brings the relay 3 into a feeding state to supply the second DC voltage via the second power line L2.

    Abstract: A control system includes a load including an operative part, and a control device for supplying AC power to the load through a power line and operating the operative part. The control device includes an interruption mechanism and a transmission mechanism. The load includes a controller. The transmission mechanism transmits a predetermined control signal to the load through the power line by blocking the power supply to the load by the interruption mechanism for a time duration shorter than a half cycle of AC output. The controller controls the operative part based on the control signal received from the control device.

  • Patent number: 8867345
    Abstract: An intelligent electronic device segregates urgent data frames from non-urgent data frames on reception so that the urgent data frames may be handled with greater priority. A switching device is disposed between an external network interface and multiple internal network ports. Based on a network data type indicia, urgent data frames are routed to one of the ports, and non-urgent data frames are routed to another port. A processor coupled to the internal network ports handles urgent data frames before handling any non-urgent data frames.

  • Patent number: 8868935
    Abstract: A system and method for providing power control in a power management integrated circuit. A power management integrated circuit may comprise a communication interface module that receives power supply information from at least one electrical device external to the power management integrated circuit. The power supply information may, for example, comprise information related to a first electrical power. The power management integrated circuit may also comprise a power regulator module that determines a regulated power signal based, at least in part, on a portion of the power supply information. The regulated power signal may correspond to the first electrical power. For example, the regulated power signal may comprise the first electrical power or cause another circuit to output the first electrical power. The power management integrated circuit may then output the regulated power signal to at least one electrical device external to the power management integrated circuit.
