  • Publication number: 20120229831
    Abstract: A power-supply control device includes a power-supply-state transition control section, body-capable-of-movement detection sections, a time measuring section, a transition-instruction section, and an instruction-provision-time postponement section. The power-supply-state transition control section shifts a state of an operation target section from one state to another state among power-supply states and a non-power-supply state. The body-capable-of-movement detection sections detect a body capable of movement in a region. The time measuring section measures a time over which the operation target section in one of the power-supply states is not used. The transition-instruction section provides, for the power-supply-state transition control section, an instruction for shifting to the non-power-supply state. The instruction-provision-time postponement section postpones an instruction-provision time at which the instruction is provided by the transition-instruction section.

  • Publication number: 20120127518
    Abstract: A power-supply monitoring device includes a power-supply control section, a detection section, a determination section, a control section, and an attachment section. The power-supply control section receives supply of power from a mains power source section, and selectively sets a power supply mode and a power saving mode. The detection section detects, in a predetermined region, a body capable of movement including a user who intends to use a processing section. When the body capable of movement is detected, the determination section determines whether switching from the power saving mode to the power supply mode is to be performed to obtain a result. The control section controls the power-supply control section on the basis of the result. The attachment section is attached to the detection section so that a detection region including a position or having an area for identifying the user is adjustable.

  • Publication number: 20120127538
    Abstract: A power-supply control device includes a power-supply control section, a first detection section that detects whether or not a body capable of movement is moving, a second detection section that detects whether or not the body capable of movement exists, and an instruction section. The power-supply control section receives supply of power from a mains power source section, and selectively sets a power supply mode, in which power is supplied to a processing section, and a power saving mode, in which supply of power to the processing section is stopped. The first and second detection sections and the instruction section are caused to operate at least in the power saving mode. The instruction section provides, for the power-supply control section, an instruction for switching between the power supply mode and the power saving mode.

  • Publication number: 20110320842
    Abstract: A power supply control device including a mode switching controller, a first power supply section, a second power supply section, a third power supply section, a wiring system opening and closing unit and a controller. During the sleep mode, the first power supply section continues to supply power to a specific control system, the second power supply section shuts off its supply of power, and the third power supply section supplies power to the specific control system by a separate system to the specific control system. The wiring system opening/closing unit sets a power supply wiring system of the commercial power source to an open state or a closed state. When the third power supply section is supplying power during the sleep mode, the controller controls the wiring system opening and closing unit and sets the power supply wiring system of the commercial power supply to the open state.
