Abstract:
In an image forming apparatus connected to a network, an interface unit receives information requesting data via the network and transmits response data to the network during a normal mode and a standby mode. A storage unit stores the response data being read out during the standby mode. A normal-mode response data generating unit generates the response data during the normal mode. An information storing unit, during the normal mode, stores, in the storage unit, information about the response data. A standby-mode response data generating unit, during the standby mode, generates the response data from the information about the response data, and stores a response frequency of the information. A stored response data deleting unit deletes, if an amount of the information exceeds a storage capacity of the storage unit, the information with the response frequency that is lower than a specified threshold.
Abstract:
Provided is an image processing apparatus including: a grouping preference unit configured to register user preference information on a storage device based on a user operation, the user preference information indicating how objects within an image are to be classified into groups; an image analysis unit configured to detect the objects within the image; and a grouping unit configured to read the user preference information from the storage device and classify the objects detected within the image into the groups indicated in the read user preference information.
Abstract:
A server apparatus includes a controller circuit configured to obtain a use time period and a use amount of each of multiple client apparatuses, calculate a use percentage of each of the multiple client apparatuses of each use time period on a basis of the use amount, determine a recommended time period on a basis of the use percentage of each of the multiple client apparatuses, the recommended time period being a time period in which a largest number of client apparatuses are to be maintained, and specify the largest number of client apparatuses to be maintained during the recommended time period.
Abstract:
An information processing apparatus includes: a sub controller; a main controller; and a communication interface, the main controller being configured to detect a trigger to start the sleep mode, then create port-dependent TCP packet patterns and port-dependent UDP packet patterns, the port-dependent TCP packet patterns being packet patterns specifying all in-use TCP ports, the port-dependent UDP packet patterns being packet patterns specifying all in-use UDP ports, determine that a total number of the port-dependent UDP packet patterns and the port-dependent TCP packet patterns exceeds a maximum value, then delete all the port-dependent TCP packet patterns, create port-independent TCP packet patterns for different TCP protocols, respectively, the port-independent TCP packet pattern being one packet pattern specifying no TCP port, and supply the port-dependent UDP packet patterns and the port-independent TCP packet patterns to the sub controller, and start the sleep mode.

Abstract:
An electronic device includes a first processing device, a second processing device, and a power state control unit. The power state control unit controls a power state of the electronic device. The power state includes a normal state and a power-saving state. The second processing device ensures the execution of the process according to the received data in the normal state. The power-saving state at least temporarily stops supplying the second processing device with electric power while the first processing device ensures the execution of the process according to first received data. When a temporary wake up of the electric power supply to the second processing device is intermittently repeated in the power-saving state, the power state control unit determines a time interval from a termination of the temporary wake up to a start of a subsequent temporary wake up based on a specific condition during the temporary wake up.
Abstract:
An image forming apparatus according to an embodiment of the present disclosure includes a receiving unit, a controlling unit, an information accumulating unit, a sleep mode response data generating unit, and a transmitting unit. The receiving unit receives information requesting data. The controlling unit, in a normal mode, generates first response data after receiving the information requesting data. The information accumulating unit accumulates information associated with the first response data. The sleep mode response data generating unit, in a sleep mode, generates second response data on the basis of the information accumulated by the information accumulating unit. The transmitting unit transmits one of the first and the second response data.
