Wearable mobile terminal
First Claim
1. A wearable terminal, comprising:
- a main body comprising a side configured to contact a body part of a user;
a photo plethysmography located at the side of the main body and comprising;
a transmitter configured to output a signal; and
a receiver configured to detect a reflection signal that is reflection of the output signal;
a cover of the main body configured to cover the photo plethysmography, the cover comprising;
transparent units aligned with the transmitter and the receiver, the transparent units configured to pass the output signal and the reflection signal; and
a barrier unit positioned between the transparent units and configured to shield the output signal and the reflection signal;
a rubber located between the cover and the photo plethysmography, the rubber including openings that are aligned with the transparent units, and at least one of the openings also aligned with the transmitter and at least one of the openings also aligned with the receiver such that the rubber is configured to block the signal output from the transmitter directly flowing into the receiver; and
a controller configured to measure a heart rate of the user based on the detected reflection signal.

Abstract
A wearable terminal can include a main body configured to be in contact with a body of a user using one side of the main body, a photo plethysmography including a transmitter combined with one side of the main body and outputs a output signal, and a receiver detecting a reflection signal corresponding to the output signal returned, a cover configured to cover the photo plethysmography and be combined with the main body and a controller configured to measure a heart rate based on a reflection signal measured by the photo plethysmography. The cover is combined with the main body and parts corresponding to the transmitter and the receiver of the photo plethysmography include transparent units through which the output signal and the reflection signal are passing and a barrier unit positioned between the transparent units and shielding the output signal and the reflection signal.

4. A wearable terminal, comprising:
-
a main body comprising a first side configured to contact a body part of a user when the wearable terminal is worn by the user and a second side that is an opposite side of the first side; a photo plethysmography located at the first side of the main body and comprising; a transmitter configured to output a signal, and a receiver configured to detect a reflection signal that is a reflection of the output signal from a blood cell in a blood vessel of the user; an acceleration sensor configured to detect movement of the main body when the wearable terminal moves in a first direction toward a direction that the first side faces or in a second direction toward a direction that the second side faces according to movement of the body part, the second direction being an opposite direction of the first direction; and a controller configured to; reduce a first size of the detected reflection signal in response to detection, by the acceleration sensor, of the movement of the main body in the first direction; amplify a second size of the detected reflection signal in response to detection, by the acceleration sensor, of the movement of the main body in the second direction; calculate reflection signal data based on the first or second direction and a speed of the movement detected by the acceleration sensor by compensating the reflection signal; and calculate a heart rate of the user based on a number of changes in the reflection signal data per reference time. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A method for controlling a wearable terminal comprising a main body, wherein the main body comprises a first side configured to contact a body part of a user when the wearable terminal is worn by the user and a second side that is an opposite side of the first side, the method comprising:
-
outputting a signal to the part of a user; receiving a reflection signal that is a reflection of the output signal from a blood cell in a blood vessel of the user; detecting movement of the main body when the wearable terminal moves in a first direction toward a direction that the first side faces or in a second direction toward a direction that the second side faces according to movement of the body part, the second direction being an opposite direction of the first direction; reducing a size of the detected reflection signal in response to detection of the movement of the main body in the first direction; amplifying a size of the detected reflection signal in response to detection of the movement of the main body in the second direction; calculating reflection signal data based on the first or second direction and a speed of the detected movement by compensating the received reflection signal; and calculating a heart rate of the user based on a number of changes in the reflection signal data per reference time. - View Dependent Claims (18, 19)
