  • 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.

  • Publication number: 20120265960
    Abstract: A CPU measures time. A memory unit stores the values of the times measured by the CPU as data groups for each measuring of time, and stores the data groups in association with protection information showing whether the data groups are in a protection state or an unprotected state. An input switch receives an instruction as an input. The CPU sets protection information stored in the memory unit on the basis of the instruction received by the input switch. Further, the CPU deletes the data of data groups in an unprotected state from the memory unit, on the basis of the protection information stored in the memory unit, when there is no capacity for storing the measured time values in the memory unit.
