Abstract:
1. An apparatus for determining a heart rate of a person, the apparatus comprising: at least two detectors configured to detect a blood pulse optically from the blood circulation of the person and to be placed in optical communication with and substantially adjacent to the skin of the person, wherein the blood pulse is detected by the at least two detectors from a same body part; and a processor configured to verify that the blood pulse has been detected based on whether a first detection of the blood pulse associated with one of the at least two detectors occurs before a second detection of the blood pulse associated with another of the least two detectors, the processor being configured to determine the heart rate of the person on the basis of the detected blood pulse, wherein the processor is further configured to verify that the blood pulse has been detected based on whether the detections by the at least two detectors are separated by a predetermined time difference.
