  • Patent number: 11470214
    Abstract: An information processing apparatus includes a component to be maintained, a maintenance engine configured to perform maintenance on the component, and circuitry. The circuitry turns on a power supply to the apparatus at a power-on time set in advance by a timer; acquires, from a memory, a scheduled time of periodic maintenance to be executed on the component; turns on the power supply at a time prior to the scheduled time of the periodic maintenance; and shuts down the apparatus in response to an end of the periodic maintenance. In response to an arrival of the power-on time by the timer during execution of the periodic maintenance, the circuitry controls a state of the power supply to be kept at an on-state after the periodic maintenance ends.

  • Patent number: 11316502
    Abstract: Systems and methods for detecting an open condition in a master-slave configuration are described. In an example, a controller can be integrated in a slave device of a master-slave configuration. The controller can be configured to activate a current source to supply a current to a pin of the slave device. The controller can be further configured to compare a voltage measured at the pin of the slave device with a reference voltage. The controller can be further configured to, based on the comparison, determine a presence or an absence of an open condition associated with the pin of the slave device. The controller can be further configured to output a signal representing the determination of the presence or the absence of the open condition to a master device.
