The present disclosure provides a method and a device in a communication node for wireless communications. The communication node in the present disclosure first receives first information, and then transmits a first radio signal; a length of a time interval between a start time for transmitting the first radio signal and a first reference time is equal to a sum of a first timing adjustment and a second timing adjustment, the first timing adjustment being one of X candidate timing adjustments, the X being a positive integer greater than 1; the second timing adjustment is used for determining a transmission timing of a radio signal transmitted before the first radio signal in time domain; a transmitter of the first radio signal determines the first timing adjustment out of the X candidate timing adjustments by itself. The present disclosure can improve uplink synchronization performance.

An optical scanning device includes a light source, a deflector, a random number generator, a selection part, a random number assignment part and an exposure control part. The light source includes a plurality of light emitting parts arranged in a predetermined direction at fixed intervals in a sub-scanning direction. The random number assignment part is configured to assign a random number sequence to each light emitting part constituting a set of target light emitting parts as an index for specifying a timing at which a light emitting time of the set of target light emitting parts is set to a correction value different from a reference value and to update the assignment of the random number sequence at a random number update period. The random number update period coincides with a scanning period of each light emitting part constituting the set of target light emitting parts.

There is provide a photoelectric conversion device. In a first mode, a control unit performs control such that a signal output from each of a plurality of pixels is held in a corresponding holding unit. In a second mode, the control unit performs control of outputting a signal from the holding unit corresponding to a pixel in a first column and control of holding a signal based on a pixel in the first column in the holding unit corresponding to a pixel in a second column in parallel in the same period.

An image forming apparatus includes a measurer that measures biometric information of a user, an analyzer that analyzes the measured biometric information, a job accepter that accepts jobs, a job executer that executes the jobs accepted by the job accepter, a hardware processor configured to estimate a job execution time period during which the job executor executes each of at least one of a plurality of jobs accepted by the job acceptor, to estimate a finish time point at which the analyzer finishes the analysis, and, in response to start of measurement of the biometric information by the measurer, to change execution order of a relating job, which relates to the user who is a subject of the measurement by the measurer, among the plurality of jobs such that a period during which the relating job is executed and the finish time point have a predetermined relationship.

A scanner has a first sensor array; a second sensor array; a timing controller that individually outputs at different times a first drive signal that drives the first sensor array, and a second drive signal that the second sensor array; and a light source configured that emits and illuminates a document during periods between the first drive signal and the second drive signal output next after the first drive signal, and periods between the second drive signal and the first drive signal output next after the second drive signal.

Provided is an image processing apparatus that efficiently performs time-divisional image processing tasks related to image formation of an image forming apparatus. A time division determination unit configured to determine and switch which of divided work items to execute based on execution time in a condition where at least one first task to be processed at a specific pace and at least one second task to be processed at best effort are respectively divides into smaller work items. A task execution unit executes the work item switched by the time division determination unit in a time division. This work item uses something as like first band data and second band data.

An apparatus, system, and method allow a user to initiate a live stream that includes retrospectively captured images. Initiating the live stream includes providing provisional data that includes retrospectively captured images to a wireless radio.

An image forming apparatus includes a sensor configured to detect an original, a nonvolatile storage that includes a semiconductor area, a setting unit configured to execute a setting for dividing the semiconductor area into a plurality of areas, and a controller configured to execute Trim processing on the divided areas in response to passing of a predetermined time period while the image forming apparatus is in a standby state. The controller is configured to stop the Trim processing based on a detection of the original detected by the sensor while the Trim processing is executed.

An image forming system includes an image former; a reader that executes reading a document or a sheet; a post processor that applies post processing to the document or the sheet; and a controller. The controller controls the image formation, the reading and the post processing, judges the requested degree of importance of reading for a reading target on the document or the sheet, judges existence or nonexistence of an overlap between an execution timing of the reading and a timing of generation of vibration at the post processing, judges the necessity of a countermeasure to prevent the overlap from occurring with reference to the degree of importance of reading and the existence or nonexistence of the overlap, and controls the execution timing of the reading and the post processing to prevent the overlap from occurring when the controller determines that the countermeasure is necessary.
