Abstract

A wearable electronic device and an emergency method thereof are provided. The wearable electronic device includes a host and a strap. The host senses physiological information of a user by using a sensor. When the physiological information is determined as being abnormal, the host sends an enabling signal to the strap by a transmitting coil to enable the strap. After the strap is enabled, a warning light module displays a warning message based on the enabling signal.

Claims

1. A wearable electronic device, comprising:

a host, comprising;

a transmitting coil;

a sensor, sensing physiological information of a user;

a power supply device, coupled to the sensor and the transmitting coil, and supplying power to the host;

a power manager, coupled to the power supply device; and

an encoder, coupled to the power manager and the sensor, and forming an enabling signal by carrying an emergent signal as a carrier on a power signal in the condition that the physiological information is determined as being abnormal; and

a strap, detachably assembled to the host, wherein the strap is in a power-off state before the transmitting coil transmits the enabling signal to the strap and the strap comprises;

a receiving coil, coupled with the transmitting coil; and

a decoder, coupled to the receiving coil and decoding the enabling signal to obtain the emergent signal;

a warning light module, coupled to the receiving coil, wherein

in a condition that the host determines the physiological information as being abnormal, the transmitting coil transmits the enabling signal to the receiving coil of the strap to enable the strap, and

in a condition that the strap is enabled, the warning light module is activated to operate by utilizing the power signal and the warning light module displays a warning message based on the emergent signal.

2. The wearable electronic device according to claim 1, wherein the wearable electronic device is a watch, the host is a watch body, and the strap is a detachable watchstrap.

3. The wearable electronic device according to claim 1, wherein the strap further comprises:

a microprocessor, coupled between the decoder and the warning light module, and converting the emergent signal into the warning message of the warning light module after receiving the emergent signal from the decoder.

4. The wearable electronic device according to claim 1, wherein the strap comprises a connection portion and is connected with the host through the connection portion.

5. The wearable electronic device according to claim 4, wherein the receiving coil is accommodated in the connection portion, and the connection portion is made of a shielding material.

6. The wearable electronic device according to claim 1, wherein the warning light module is a light emitting diode (LED) module.

7. An emergency method of a wearable electronic device comprising a host and a strap, the method comprising:

sensing physiological information of a user by the host;

when the physiological information is determined as being abnormal by the host, forming an enabling signal by carrying an emergent signal as a carrier on a power signal, and transmitting an enabling signal to the strap to enable the strap by the host, wherein the strap is in a power-off state before the enabling signal is transmitted to the strap; and

in a condition that the strap is enabled, decoding the enabling signal to obtain the emergent signal, activating a warning light module to operate by utilizing the power signal and displaying a warning message based on the enabling signal by the warning light module.
