A power control device includes a power supply, an integrated scanner assembly (ISA), an image forming engine including a general engine unit and a special engine unit, a main power switch, a special engine unit power switch, and a processor including an independent power controller, and the processor to control power supplied to the ISA and the general engine unit by closing the main power switch through the independent power controller, to receive specification information from the ISA activated by the supplied power, to receive state information on the image forming engine from the general engine unit activated by the supplied power, and to supply power to the special engine unit by closing the special engine unit power switch after receiving the specification information and the state information.

An image forming apparatus communicates with another device and includes a processor that controls the communication. A control unit controls the apparatus to operate in one of at least a first power saving state, a second power saving state, and a normal state. In the first power saving state, the apparatus is controlled so that an image forming unit, an image reading unit, and the control unit are not activated, and a communication device is activated. In the second power saving state, the apparatus is controlled so that at least one of the image forming unit and the image reading unit are not activated, and the communication device and the control unit are activated. In the normal state, the apparatus is controlled so that at least the image forming unit, the image reading unit, the communication device, and the control unit are activated.

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.

An information processing apparatus includes a control unit, a storage unit configured to store a program to be executed by the control unit, a verification unit configured to read the program from the storage unit and to verify the read program, and a light-emitting unit configured to be changed to a predetermined light-emitting state or to be changed from the predetermined light-emitting state based on a result of the verification of the program by the verification unit.

A semiconductor device includes a load element, a switching element, and a processor. The load element controls a temperature of the semiconductor device with an electric current supplied to the load element. The switching element switches between supply of an electric current to the load element and a cut-off of the supply. The processor controls the switching element. The processor controls the electric current to be supplied to the load element through the switching element so that the semiconductor device has a series of temperatures represented by a specific temperature profile.

An electronic device and a method of presenting an error in power off of the electronic device are provided. The electronic device includes a power switch that is manually set to ON and OFF, an actuator that sets the power switch to OFF, and a controller that outputs a control signal for controlling whether to supply power to the actuator. The electronic device notifies different information based on whether or not the power has been supplied to the actuator after the controller has output the control signal.

An information processing apparatus includes a control unit, a storage unit configured to store a program to be executed by the control unit, a verification unit configured to read the program from the storage unit and to verify the read program, and a light-emitting unit configured to be changed to a predetermined light-emitting state or to be changed from the predetermined light-emitting state based on a result of the verification of the program by the verification unit.

A framed collectible for displaying a continuously-looping playback of a digital video file is provided, wherein a display panel is controlled by a display controller to play at least one video file in a continuous loop on the display panel only while an output signal from a magnet sensor indicates no proximity to a magnet proximal to the back side of the display panel. The display controller has a printed circuit board that incorporates at least one processor and at least one memory that contains at least one video file. The memory, which in an embodiment can be flash memory, is factory programmed and therefore the memory content cannot be changed by an end user. Packaging for storage and shipping of the framed collectible is also provided, which incorporates a magnet that is sensed by the magnet sensor to keep continuously-looping video playback switched off while the device is stored.

An electronic apparatus includes processing devices including first circuitry, a controller including second circuitry, and a memory storing a time-out time and an extension time. The first circuitry that detects an abnormality, transmits an abnormality occurrence notification, transmits a preparation completion notification, and transmits an extension request. The second circuitry transmits a restart preparation instruction to the processing devices excluding a source of the abnormality occurrence notification, waits for the preparation completion notification until an elapse of the time-out time. The second circuitry restarts the processing devices in response to the preparation completion notification from the processing devices or the elapse of the time-out time. The second circuitry extends the time-out time by the extension time in response to the extension request and restarts the processing devices in response to the preparation completion notification or the elapse of the extension time.

Provided is an image forming apparatus that determines the usage status of a function by a user and improves power consumption efficiency. The image forming apparatus is capable of switching between an energy saving mode and a normal mode in which power consumption is larger than that of the energy saving mode. The power supply control unit determines whether or not power is supplied depending on the usage status of the function by the user. The power supply control unit controls the power supply of the operation panel unit, the document reading unit, and the image forming unit to be turned on or off, respectively, when returning from the energy saving mode to the normal mode according to the determination.
