Patent number: 9111437Abstract: A time interval setting unit sets a time interval that depends on the number of items of data stored by a storage unit. A storage processing unit stores the data in the storage unit at every time interval that is set by the time interval setting unit.

Publication number: 20140121567Abstract: 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.Type: ApplicationFiled: October 22, 2013Publication date: May 1, 2014Applicant: SEIKO INSTRUMENTS INC.Inventors: Takanori HASEGAWA, Akira TAKAKURA, Keisuke TSUBATA, Kazuhiro KOYAMA

Patent number: 8682420Abstract: 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.Type: GrantFiled: November 14, 2012Date of Patent: March 25, 2014Assignee: Seiko Instruments Inc.Inventors: Keisuke Tsubata, Takanori Hasegawa, Akira Takakura, Katsuya Mugishima, Kazuo Kato, Kazuhiro Koyama, Hisao Nakamura
