Analog electronic watch system and analog electronic watch
In an analog electronic watch system, a terminal equipment detects current display positions of hands in an image of the hands and a dial plate, and generates current display time information based on the current display positions. An analog electronic watch corrects the display positions of the hands based on the display time information. The terminal equipment at least acquires hand identification information including hand shape information about a shape of the hand of the analog electronic watch based on watch identification information transmitted from the analog electronic watch. The terminal equipment detects the current display positions based on the hand identification information, and transmits display time information based on the current display positions to the analog electronic watch.
Timepiece and indicating hand control method
A timepiece includes a display unit including a first indicating hand and a dial so as to display a time, in which the dial has a first scale having a number for showing an absolute value of a positive numerical value within a plurality of numerical values indicated by the first indicating hand, a second scale having a number for showing an absolute value of a negative numerical value within the plurality of numerical values, a first sign for showing that the numerical value indicated by the first indicating hand is positive, and a second sign for showing that the indicated numerical value is negative.
Timepiece movement and timepiece
A timepiece movement includes a control unit that determines a position of an indicating hand by detecting a rotation state of a rotor, and a train wheel that transmits a drive force of a stepping motor to the indicating hand, and that has a first gear, and a second gear and a third gear which mesh with the first gear. The first gear has a reference load unit that causes fluctuations in a load applied to the rotor in each case of meshing with the second gear and the third gear. A first line segment which connects a center of the first gear and a center of the second gear to each other forms an angle smaller than 180° with a second line segment which connects the center of the first gear and a center of the third gear.
Electronic watch and method for controlling electronic watch
An electronic watch includes a motor including a coil, a driver controlled to an ON state for supplying a driving current to the coil and an OFF state for not supplying the driving current, a driver controller configured to control the driver to the ON state or the OFF state depending on a value of a current flowing through the coil, and a polarity switcher configured to switch a polarity of the driving current when a prescribed condition is satisfied after detecting that an ON time, which is a duration of the ON state of the driver controller, reaches a maximum.
NOTIFICATION CONTROL DEVICE, WATCH, NOTIFICATION CONTROL METHOD, AND NON-TRANSITORY RECORDING MEDIUM
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.
WATCH, POINTER CONTROL METHOD, AND NON-TRANSITORY RECORDING MEDIUM
A watch includes a pointer that rotates and indicates a time, a notifier that performs a notification operation to a user in a mode other than a visual mode, and a processor that controls the rotation of the pointer and the notification operation of the notifier. The processor is configured to control the pointer to cause the pointer to rotate faster than a rotation corresponding to a passage of time and move to a specified position and, when the pointer arrives at a notification position while the pointer is moving fast, control the notifier to cause the notifier to perform the notification operation.
ELECTRONIC TIME PIECE
An electronic time piece includes a dial, a sub dial provided to the dial, a control circuit that controls operation of a function hand disposed on the sub dial, a plurality of terminal portions, a wire that electrically connects the plurality of terminal portions with the control circuit, a push button that receives operation by a user and switches an electrical connection state between one terminal portion of the plurality of terminal portions and the control circuit. The one terminal portion of the plurality of terminal portions and other terminal portion are electrically connected to the control circuit by a common wire.
Movement and timepiece
A train wheel unit is provided with a first wheel which is configured by a material including a conductive polymer and a carbon powder, and a second wheel which is configured by a metal material. The train wheel unit transmits a drive force of an electric motor module which is driven using a battery as an electrical power source.
Electronic timepiece and motor control circuit
An electronic timepiece can prevent overrunning when driving a motor at a high speed. The electronic timepiece has a controller that controls a driver to an on state or an off state according to the current value detected by the current detector; a polarity changer that determines driving one step of the motor ended and changes the polarity of the drive current when the on time or off time is detected to meet a specific condition; and a drive period adjuster that sets the terminal supplying the drive current to the coil to a first state if the remaining drive step count is greater than the remaining count evaluation number, and if the remaining drive step count is less than or equal to the remaining count evaluation number, sets the terminal to a second state in which the brake force applied to the rotor is greater than in the first state.
Timepiece with increased information view ability
In a timepiece, moments of inertia of a first pointer and a second pointer that are for displaying first information and second information, respectively and that have a same rotation axis are the same. As a result, parts having identical specifications may be used in a drive mechanism of the first pointer and a drive mechanism of the second pointer. Further, color schemes of the first pointer and second pointer differ. As a result, a user may easily distinguish the first pointer and the second pointer.
