  • Patent number: 10175748
    Abstract: A personal computer or other electronic device may be powered by an external power supply and may have a legacy ambient temperature sensor e.g. because a fan whose speed is controlled by a controller, uses as an input, inter alia, ambient air temperature received from the legacy temperature sensor which may be disposed adjacent the fan. A controller may be provided which limits the current based on ambient air temperature reading/s flowing out of the sensor thereby to optimize power consumption relative to conventional “worst-case-assumption based” control of the current, in which current supplied is limited, mindful of a pre-set worst-case temperature assessment, to an un-necessarily low level of current.

  • Patent number: 10146291
    Abstract: A serial point-to-point link interface to enable communication between a processor and a device, the high speed serial point-to-point link interface including a transmitter to transmit serial data, a receiver to deserialize serial data, and control logic to implement a protocol stack. The protocol stack supports a plurality of power management states, including an active state, a first off state, in which a supply voltage is maintained, and a second off state, in which the supply voltage is not to be provided to the device. The protocol stack provides a default recovery time to allow the device to begin a transition from the first off state to the active state prior to accessing the device. The protocol stack further provides for accessing the device prior to expiration of the default recovery time to complete the transition based on a device-advertised recovery time.

  • Patent number: 10133333
    Abstract: A method includes a power supply system receiving a first request for a first quantity of power for a first time period from a first unit. The system generates a first quote based on an available power generation capacity, environmental factors and a forecasted level of power consumption. The system transmits the first quote to the first unit. The system receives a second request for a second quantity of power for a second time period. The system generates a second quote based on the same factors as the first quote. The system transmits the second quote to the second unit. The value of the first quote and the value of the second quote are set to discourage demand in a first mode and to encourage demand in a second mode to maximize efficient operating levels of the power generation sources in both the first mode and the second mode.
