A hand display control device includes a processor. The processor causes an oscillation circuit to output a first frequency signal or a second frequency signal to a first processing circuit that executes processing for operating a hand in response to the first frequency signal. The oscillation circuit outputs the first frequency signal or the second frequency signal by switching. The second frequency signal is higher in frequency than the first frequency signal. The processor controls whether to output the second frequency signal to a second processing circuit that performs previously determined certain processing in response to the second frequency signal. The processor controls the switching of the oscillation circuit depending on whether the certain processing is performed. The processor prohibits the first processing circuit from performing a specific operation of the hand while the second processing circuit is performing the certain processing.

A thermal compensation system is provided for a liquid-filled inflexible chamber of a device. The chamber has at least one exposed, at least partially transparent surface allowing an outside observer to observe at least one liquid and comprises a mechanism accommodating thermal expansion and/or contraction of the liquids. The mechanism is disposed so as to be substantially invisible to the observer.

A notification control device acquires a plan of a subject, and causes a notifier to notify current day plan content information in a first notification mode and future plan content information in a second notification mode that differs from the first notification mode. The current day plan content information is information about the acquired plan of the subject for current day or is information about the acquired plan of the subject for a certain period including the current day. The future plan content information is information about the acquired plan of the subject for the future of the certain period or is information about the acquired plan of the subject for a certain future period not including the current day.

A display device includes a substrate having a through-hole. The display device also includes a display unit formed on the substrate and surrounding the through-hole, and the display unit is configured to display an image and includes pixels.

A digital display and a digital time device are provided, which includes a housing, a drive assembly, display assemblies and a mainboard assembly. The housing is provided with seven windows arranged to form the shape of the character “”. The mainboard assembly is fixedly connected to the housing and is located behind the windows. Seven curved grooves are provided inside of the drive assembly. The display assemblies include display sheets and pull rods. One end of each pull rod is fixedly connected to the display sheets. The display sheets are slidingly connected to the mainboard assembly. There are seven display assemblies. Each pull rod is slidingly connected to the curved grooves in one-to-one correspondence, and each display sheet is one-to-one correspondence with the windows. The present invention can achieve many advantages, such as low power consumption, great waterproof, strong moisture resistance capabilities and high stability.

Aspects of the disclosure provide a hybrid smartwatch that incorporates digital technology with an analog timepiece in a wristwatch form factor. A digital display layer of a non-emissive material is configured to present notices, data, content and other information. An analog display layer includes one or more hands of the timepiece, and overlies the digital display layer. The hands may be controlled by a processor through micro-stepper motors or other actuators. Physical motion of the hands is simultaneously coupled with arrangement of content or other elements on the display layer, which results in numerous types of hybrid visualizations. This includes temporal presentations using hourly, daily, monthly or other time scales. Shape-shifting of the watch hands between 2D and 1D arrangements can linearly focus on certain information. And various content-aware layouts can highlight, bracket, occlude or otherwise emphasize or deemphasize displayed information.

A timepiece includes at least one time-of-day hand rotatable relative to a first dial and a first pair of temporal calendar mechanical elements independently rotatable relative to each other, and relative to the at least one time-of-day hand. Controlled rotation of the respective temporal calendar mechanical elements is synchronizable relative to temporal calendar information on an external device.

A device for selection of a combination of motifs for a timepiece, including an inner disc, and a coaxial outer disc, the inner disc having a smaller diameter than the outer disc, the discs including angular sectors of the same size, at least two angular sectors of each disc bearing a motif on their periphery; a device for actuation permitting rotation of the inner disc, and a gear device for coupling the two discs according to a reduction ratio; a dial extending opposite the inner disc, the dial including an aperture to put a motif of the inner disc and a motif of the outer disc into correspondence, such that a complete rotation of the inner disc gives rise to a rotation of the outer disc by one angular sector, the size of the aperture being sufficiently large for each motif of the outer disc to be in correspondence successively with all the motifs of the inner disc, when the inner disc is rotated.
