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.

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.

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.
