  • Patent number: 9780791
    Abstract: A switch comprising a spin-transistor and a first control wire. The spin-transistor is configured so that when a magnetic field applied to the spin-transistor is less than a threshold value, the transistor is in a conductive state in which electric current flows through the spin-transistor. When the magnetic field applied to the spin-transistor is greater than the threshold value, the spin-transistor is in a resistive state in which the electric current flowing through the spin-transistor is substantially reduced. The first control wire is for receiving a current to affect the magnetic field applied to the spin-transistor.

  • Patent number: 8706652
    Abstract: Systems and methods for controlling power consumption in a computer system. For each of a plurality of interactive applications, the method changes a frequency at which a processor of the computer system runs, receives an indication of user satisfaction, determines a relationship between the changed frequency and the user satisfaction of the interactive application, and stores the determined relationship information. The determined relationship can distinguish between different users and different interactive applications. A frequency may be selected from the discrete frequencies at which the processor of the computer system runs based on the determined relationship information for a particular user and a particular interactive application running on the processor of the computer system. The processor may be adapted to run at the selected frequency.
