  • Patent number: 10132627
    Abstract: An electronic device has a storage unit that stores unit information relating to movement with respect to each of an elevating state and a horizontal movement state and an altitude measurement unit that measures a series of altitudes. An altitude change determination unit determines whether the movement is the elevating state or not using a first determination section having a first altitude range based on a first set of altitudes within the measured series of altitudes, and determines whether the movement is the horizontal movement state or not using a second determination section having a second altitude range smaller than the first altitude range and based on a second set of altitudes within the measured series of altitudes. A movement distance calculator reads from the storage unit the unit information corresponding to the state determined by the determination unit and calculates a movement distance based on the read unit information.

  • Patent number: 9076371
    Abstract: A display device includes independently driven common and segment terminals. The common and segment terminals are connected to display components divided into display blocks that are turned ON to perform a display function and are turned OFF so as to not perform the display function. A first driver drives the common terminals using a scanning signal of a predetermined period and a second driver drives the segment terminals using a segment signal synchronized with the scanning signal to correspond to a display signal, so that the display components perform a display corresponding to the display signal. The first driver separates the common terminals into common terminal blocks and drives the common terminals. The first and second drivers perform the driving so that the common and segment terminals which are connected to display blocks that are turned OFF are not supplied with a turn-off signal and are maintained at ground potential.

  • Patent number: 9036455
    Abstract: An electronic timepiece is operated with a power-supply voltage from a secondary battery charged with a voltage from a solar panel. An oscillation circuit generates and supplies a clock signal to a CPU when the voltage charged to the battery is lower than a first voltage. A reset circuit resets the CPU when the voltage charged to the battery does not exceed a second voltage higher than the first voltage, and cancels the reset of the CPU when the voltage charged to the second battery exceeds the second voltage. The CPU starts an operation when the voltage charged to the secondary battery exceeds the second voltage and the reset is cancelled, and performs a time-of-day display on a display unit when the voltage charged to the secondary battery is equal to or higher than a third voltage higher than the second voltage.

  • Publication number: 20140121567
    Abstract: A display control unit performs switching between internal measurement information (for example, a lap time and others) and living-body information (for example, the number of heartbeats) indicated by a living-body signal for display on a display unit, based on whether or not a receiving unit acquires the living-body signal (for example, a heartbeat signal). Accordingly, a user can switch between displaying living-body information indicated by a living-body signal on a running watch (a display unit) and not displaying the living-body information indicated by the living-body signal on the running watch, depending on whether or not a chest strap is worn. Accordingly, the user does not need to perform a user operation for switching between the display of the internal measurement information and the display of the living-body information indicated by the living-body signal. Therefore, a user's laborious job of performing a display switching operation can be reduced.

  • Patent number: 8682420
    Abstract: A heartbeat measuring device has a measurement unit that measures a heart rate of a user, and an information storage unit that stores unique information regarding a heart rate unique to the user or information regarding a detected heartbeat of the user. A determination unit determines whether or not a heartbeat measurement state of the user is normal on the basis of the unique information or the information regarding a heartbeat stored in the information storage unit. An abnormality detection unit detects an abnormality corresponding to poor mounting of the heartbeat measuring device or interference due to external noise on the basis of a heart rate measured by the measurement unit. A notification unit performs a notification when the abnormality is detected by the abnormality detection unit. The notification unit changes information to be notified on the basis of a detection result by the abnormality detection unit.

  • Patent number: 8351303
    Abstract: An invention allows a stepping motor to be reliably driven to rotate when initializing the driving and allows power consumption of the stepping motor to be reduced. The controller, when initializing the driving (for example, replacing a battery), controls a main drive pulse generator to drive a stepping motor using a main drive pulse having a maximum energy and sets the generation cycle of a pulse down control signal of a pulse down counter for pulsing down the main drive pulse to a first cycle to drive the stepping motor, and when pulsing down the main drive pulse to that having a predetermined energy, changes the generation cycle of the pulse down control signal of the pulse down counter to a second cycle.
