摘要： An electronic device includes an open-close detector configured to detect an open-close state indicating whether an optical path open-close device of a film camera is open or closed, a displacement detector configured to detect a displacement of a movable portion of the film camera interlocked with a movement of an operation portion of the film camera, and control circuitry. In response to a detection result of the displacement detector, the control circuitry selects a measurement mode for measuring an open time during which the optical path open-close device is open, from a plurality of operation modes of the electronic device. In the measurement mode, the control circuitry measures the open time based on the open-close state detected by the open-close detector.

摘要： Ahead maintenance device includes a cap and circuitry. The cap is detachably attachable to a nozzle surface of a head to cover the nozzle surface having a nozzle. The circuitry causes the cap to contact the nozzle surface of the head to form a space between the nozzle surface and the cap filled with a cleaning liquid, and applies a drive waveform to a piezoelectric element of the head to apply vibration to the cleaning liquid in the space. The drive waveform causes the head to draw the cleaning liquid into an interior of the head through the nozzle.

摘要： In additional enrollment of a template in a biometric authentication system, the template is automatically enrolled on the basis of a plurality of authentication results to assure a user's convenience and security. A post-migration authentication server receives a first template and a second template from a post-migration authentication terminal, performs authentication on the basis of the comparison result between the received first template and the user's preliminarily first enrolled template, and provisionally enrolls the first template and the second template. It repeats the reception, authentication, and provisional enrollment and calculates a match probability from a plurality of comparison results of the provisionally first enrolled templates, determines whether or not to store a second enrolled template on the basis of the match probability, and automatically enrolls the second template in the post-migration authentication server.

摘要： A wiping device includes a wiping member including a web to wipe an object to be wiped, and circuitry to cause the wiping member to perform a wiping operation to wipe the object to be wiped. The circuitry causes the wiping member to perform a first wiping operation to move the wiping member relative to the object to be wiped in a first direction to wipe the object to be wiped from a wiping start side of the first wiping operation, and perform a second wiping operation to relatively move the wiping member relative to the object to be wiped in a second direction different from the first direction, to wipe the object to be wiped from a wiping finish side different from the wiping start side of the first wiping operation with the wiping member.
