  • Patent number: 9442547
    Abstract: An information processing apparatus includes a first control unit configured to control a processing unit; a first power supply that supplies power to the first control unit; a switching unit configured to switch on or off the first power supply; a second control unit configured to operate according to a setting and control the switching unit; a second power supply that supplies power to the second control unit; and a setting change unit configured to perform the setting of the second control unit so that the switching unit switches off the first power supply when a voltage of the second power supply is lower than a preset voltage, and perform the setting of the second control unit so that the switching unit switches on the first power supply when the voltage of the second power supply is equal to or higher than the preset voltage.

  • Patent number: 8726181
    Abstract: A log-information processing apparatus includes a first interface unit, a storage unit, and a control unit. The first interface unit is configured to be attached and removed to and from an image processing apparatus. When the first interface unit is connected to the image processing apparatus, the control unit performs initialization on units included in the log-information processing apparatus, acquires log information from the image processing apparatus via the first interface unit, and stores acquired log information in the storage unit.
