  • Circuit board, image forming apparatus, and method of managing reuse information of circuit board
    Patent number: 8957697
    Abstract: A circuit board includes a main part on which a processor is mounted, a cut part to be cut off from the main part at a cut section before the board is reused, and a conductor pattern wired through the cut part via the cut section and to be cut off into a plurality of patterns at the cut section as the cut part is cut off. The processor detects a difference in signal level between a level of a signal output from the conductor pattern before the cut part is cut off, and a level of the signal output from the conductor pattern after the cut part is cut off, to determine a number of times the board is reused.

  • Information processing apparatus, power source control method thereof, program thereof, and storage thereof
    Patent number: 8862908
    Abstract: An information processing apparatus includes an information storage to store information indicating a state of the information processing apparatus; an information writing processor to write the information to the information storage; a main power source and an auxiliary power source to supply power to the information writing processor; and a discharge controller to control a discharge speed of the auxiliary power source. When a voltage output of the main power source becomes a reference voltage, the discharge controller switches a power source for the information writing processor from the main power source to the auxiliary power source, and then after completing information writing to the information storage by using the information writing processor and the auxiliary power source, the discharge controller controls the discharge speed of the auxiliary power source to decrease a voltage output of the auxiliary power source to a given voltage within a given time period.
