Abstract: According to at least one embodiment, an image forming apparatus includes a first sensor, a second sensor, and a controller. The first sensor is configured to detect a user. The second sensor is configured to detect a sheet in a sheet holder. The controller is configured to change a transition mode of an operation mode based on a first detection result of the sheet in the sheet holder by the second sensor in response to the detection of the user by the first sensor when the operation mode of the image forming apparatus is a second power-saving mode, which consumes less power than a first power-saving mode.

Abstract: According to one embodiment, an image forming apparatus having a plurality of operation modes including a normal mode and a power saving mode in which power consumption is less than that in the normal mode and includes a processor. The processor is configured to acquire information about unexecuted print jobs via a communication interface or the like. The processor transitions the apparatus to the power saving mode after a preset standby time elapses after a completion of a print job by the apparatus if an unexecuted print job satisfies predetermined conditions that indicate that the unexecuted print job can be executed on the apparatus. The processor transitions the apparatus to the power saving mode sooner than the elapse of the preset standby time after the completion of the print job if none of the unexecuted print jobs satisfies the predetermined conditions.

Abstract: An image forming apparatus includes a sensor configured to detect a human in proximity to the image forming apparatus and a user input unit to receive user inputs related to functions of the image forming apparatus.

Abstract: According to one embodiment, an image forming apparatus includes an image forming unit, a fixing unit, a reading unit, and a control unit. The image forming unit forms a visible image on a sheet. The fixing unit executes a fixing process of fixing the visible image on the sheet. The reading unit executes a reading process of reading an image. The control unit starts measurement of time until shift to a power saving mode, and shifts the operation mode to the power saving mode in which power consumption is suppressed when the measured time passes a predetermined set time. The control unit stops the measurement of the time during execution of printing, which is a process involving execution of the fixing process, and continues the measurement of the time during execution of the reading process without execution of the printing.

Abstract: An image forming apparatus includes a function controller. The function controller performs control so as not to execute a conveyance function when function information, which indicates whether to restrict execution of a conveyance function for conveying a sheet for each conveyance source of the sheet or each conveyance destination of the sheet, indicates that the execution of the conveyance function is restricted. The function controller performs control to execute the conveyance function when the function information indicates that the execution of the conveyance function is not restricted.

Abstract: A portable device includes a light emission unit to emit light on a case, a clocking unit to clock time, an information acquisition unit to acquire information indicating a position and/or a state necessary for illuminating the light emission unit, and a control unit to determine whether to illuminate the light emission unit by using timekeeping information acquired from the clocking unit and the information indicating a position and a state acquired from the information acquisition unit, and to control the light emission unit under either a light emission state or an extinction state from a result of the determination.

Abstract: When first mobile router, which has a MNP, generates a key which corresponds to that MNP and transmits a registration request packet including the key to home agent, home agent stores the MNP and key of the first mobile router, and sends main mobile router registration approval. When first mobile router receives this response, it distributes the MNP and key to second mobile router in moving network. Second mobile router, which receives this, transmits a registration request packet including the MNP and key to home agent, and thereby, home agent registers second mobile router as a subsidiary mobile router. By this means, it is possible to prevent illegal acquirement of a packet addressed to a moving network by use of a mobile router which shares the network prefix (MNP).

Abstract: When an emergency mode is set, a CPU outputs an alert from an alerting unit and notifies the current position obtained by a GPS processing unit to a predetermined destination by a communication unit. When the main power is switched off, the CPU determines whether or not the emergency mode is set, and when determined that the emergency mode is set, stops power supply to display sections, etc. to pretend that the apparatus is completely switched off, but continues power supply to the GPS processing unit and communication unit to keep notifying the current position.

Abstract: In the present invention, in updating a program stored in rewritable nonvolatile memory such as Flash ROM, a program portion in a block in the nonvolatile memory is expanded in RAM which includes a portion needing an update of the program stored, and only the portion needing the update is instructed from the outside and updated among the expanded program portion. Then, the block in the nonvolatile memory is erased, and the program portion updated in the RAM is recorded again in the erased block in the nonvolatile memory.

Abstract: Packet size calculator 32 obtains coded data amount N1 storable in a single packet Comparison judging section 33 obtains the rest of coded data amount storable in the packet from the coded data amount N1 and coded data amount P already stored in the packet. The section 33 variably controls a slice length in coding section 2, corresponding to whether or not coded data amount M of a macroblock calculated in coding amount calculator 35 exceeds the rest of coded data amount storable in the packet. Since it is thus possible to perform coding with the maximum slice length storable in the packet, it is possible to complete the slice in a single packet and to decrease the number of stuffing bits.

Abstract: A digital contents editing method performs an editing operation of digital contents with a plurality of computers connected via a network. A digital contents editing apparatus or server accumulates the initial data of the digital contents and the editing operation information which is digitized, and transfers the editing operation information to clients which are involved in the editing operation. Each client then performs an editing operation of the digital contents by creating the editing operation information, in which the editing operation of the digital contents is digitized, and communicates only the editing operation information to other clients via the server and the network.
