An arbitration device comprises a determining unit that determines priority of each of a plurality of electrical devices according to at least either a position or an action status of a person present in a target area for control; and a calculating unit that calculates electrical power to be allotted to each of the electrical devices in such a way that a total of electrical power allotted to a plurality of the electrical devices is within a limit value and the electrical devices having the priority at high levels are allotted with electrical power on a priority basis.

Arbitration device, arbitration method, and computer program product

A type determination apparatus includes an acquisition unit configured to chronologically acquire power consumption consumed by an electrical device; and a determination unit configured to determine that a type of the electrical device is a type to be determined in accordance with a reference pattern representing a predetermined pattern of a power fluctuation when a fluctuation pattern of the power consumption acquired for a duration equal to or more than a reference period of time is matched with the reference pattern.

Type determination apparatus, type determination method, and computer-readable storage medium

A disclosed fixing device applying a bubble-like fixing liquid to resin-containing particles adhered to a medium so that the resin-containing particles are fixed to the medium, the bubble-like fixing liquid being formed by transforming a fixing liquid into foam that dissolves or swells at least a part of the resin, includes a control device that, based on a difference between a moisture content included in the medium after fixing and a target value of the moisture content, adjusts an application amount of the fixing liquid for a next medium.

Fixing device, image forming apparatus, and fixing method

An original is read by an original reading unit configured to read image data, at least one of the original reading unit and the original is driven by a driving motor in a sub-scan direction, and, when an amount of the image data stored by the image data storing unit becomes equal to or more than a predetermined amount, the rotational speed of the driving motor is reduced according to driving control data provided for each of current rotation angles of the driving motor for finally stopping the driving motor at a predetermined rotation angle, and a speed in a sub-scan direction at which the original reading unit reads the original is reduced. Then, main scan line data are thinned out from the image data according to thin-out data provided for each driving control data, and image data of the original are restored.

Image reading apparatus, image reading method and computer-readable information recording medium

A disclosed fixing device for fixing resin particles softened by applying a foam fixer thereon to a recording medium includes a foam fixer generator unit to introduce air bubbles into a liquid fixer containing a softener for softening the resin particles by dissolving or swelling a part of the resin particles to generate the foam fixer, a fixer application member to be brought into contact with a facing member facing the fixer application member to form an application nip and transfer the generated foam fixer to the application nip by moving its surface while carrying the foam fixer to apply the foam fixer to a surface of the recording medium carrying the resin particles at the application nip, and a foam accumulation detector unit to detect a foam accumulation formed of the foam fixer accumulated at an entrance side of the application nip.

Fixing device and image forming apparatus

An image scanning apparatus, including a contact glass having an original to be scanned on; a light source including plural dotted light-emitting elements linearly arrayed in a main scanning direction and emitting scanning light to the original; a photoelectric converter photoelectrically converting reflected scanning light from the original to produce line-image data in the main scanning direction; a halation detector receiving the line-image data from the photoelectric converter and detecting whether the line-image data has halation; and a corrector receiving information whether the line-image data has halation and correcting pixel values of all pixels of the line-image data having halation into a predetermined pixel value.

Image scanning apparatus and image scanning method

A turning-on control unit causes a turning-on unit to apply to a light source an initial voltage when turning on the light source and to apply a rated voltage after the light source has been turned on. The initial voltage is higher than the rated voltage. An image-signal control unit controls analog signals to be input to an analog signal processing unit from a turn-on time point that is a time point at which the light source is turned on until a stabilization time point that is a time point at which output of the light source is stabilized.
