Wearable device and system capable of automatically notifying personal emergency, and method thereof
First Claim
1. A wearable device for automatically notifying personal emergency comprising:
- a main body configured to be worn around a user'"'"'s body;
an ultrasonic transmitter secured to the main body, and configured to periodically transmit ultrasonic signals;
an ultrasonic receiver secured to the main body, and configured to receive the ultrasonic signals transmitted by the ultrasonic transmitter through the user'"'"'s body;
a processor secured to the main body, and configured to receive the ultrasonic signals from the ultrasonic receiver, determine a state of health of the user'"'"'s body according to the received ultrasonic signals, determine whether the state of health of the user'"'"'s body is abnormal, and generate a signal for notifying emergency personal in event the state of health of the user'"'"'s body is abnormal; and
a wireless communication unit secured to the main body, and configured to transmit the signal to at least one base station, to inform the at least one base station to determine a location of the wearable device,wherein data concerning the state of health comprises a velocity of blood flow in the user'"'"'s body;
the processor is configured to determine the velocity of blood flow according to an intensity of the received ultrasonic signals, and determine whether the state of health of the user'"'"'s body is abnormal according to the determined velocity of blood flow;
wherein the signal notifying a personal emergency comprises a first signal and a second signal;
the processor is configured to generate the first signal when the determined velocity of blood flow is less than a preset velocity and a difference between the preset velocity and the determined velocity of blood flow is less than a preset amount, and is further configured to generate the second signal when the determined velocity of blood flow is nearly zero.

Abstract
A method for safeguarding the health of a user by automatically notifying a personal emergency is applied in a wearable device worn around a user'"'"'s body or part. The method includes ultrasonic signals being periodically transmitted through the user'"'"'s body and received by a receiver. A state of health of the user'"'"' body is determined according to the ultrasonic signals and a signal notifying a personal emergency is generated if the state of health of the user'"'"'s body is abnormal. The signal is transmitted to at least one base station, to inform the base station to determine location of the wearable device for assistance-rendering purposes.
