PULSE DETECTOR
First Claim
1. A pulse detector that detects a pulse signal originating from a pulse of a subject, the pulse detector, comprising:
- a pulse wave sensor for outputting a pulse wave signal possibly including the pulse signal;
a pulse wave sensor sensitivity adjustment section that adjusts the sensitivity of the pulse wave sensor on the basis of an input signal to the pulse wave sensor or the intensity of the pulse wave signal;
a body movement sensor that detects body movement of the subject and outputting a body movement sensor signal originating from the body movement; and
an unworn-state detector that detects an unworn state in which the pulse detector has been removed from the subject, on the basis of the sensitivity of the pulse wave sensor adjusted by the pulse wave sensor sensitivity adjustment section and the body movement sensor signal outputted from the body movement sensor.

Abstract
To detect whether the pulse detector is in an unworn state, the pulse detector is provided for detecting a pulse signal that originates in the pulse of a subject has a pulse wave sensor, a pulse wave sensor sensitivity adjustment section that adjusts the sensitivity of the pulse wave sensor, a body movement sensor, and an unworn-state detector that detects that the pulse detector has been removed from the subject and is in an unworn state, on the basis of the sensitivity of the pulse wave sensor sensitivity adjustment section and a body movement sensor signal outputted from the body movement sensor.
