摘要： A vital-sign detection system is provided. The vital-sign detection system includes a vital-sign detection device and a controller. The vital-sign detection device is enabled to detect a vital-sign of a user. The controller determines whether the gets in the bed and controls the vital-sign detection device to switch to a disabled mode from a first enabled mode in response to the user getting in the bed. During a period when the vital-sign detection device is in the disabled mode, the controller determines whether the user falls asleep. In response to the user falling asleep, the controller controls the vital-sign detection device to switch to a second enabled mode from the disabled mode.

摘要： A method of efficient pocket detection is proposed. A wireless device determines whether it is in a transition state by using a plurality of low power-consuming sensors. The wireless device powers on a high power-consuming sensor if the device is in the transition state, or otherwise keeps the high power-consuming sensor off if the device is not in the transition state. The wireless device detects a current pocket mode of the device using the high power-consuming sensor if the device is in the transition state, or otherwise keeps a previous pocket mode if the device is not in the transition state.

摘要： A physiological monitoring system is provided. The physiological monitoring system includes a feature extraction device, an identifier, a processor, a physiological sensing device, and a vital-sign detector. The feature extraction device extracts biological information of an object to generate an extraction signal. The identifier receives the extraction signal and verifies an identity of the object according to the extraction signal. The processor receives the extraction signal and obtains at least one biological feature of the user according to the extraction signal. The physiological sensing device senses a physiological feature to generate a bio-signal. The vital-sign detector estimates vital-sign data of the object according to the bio-signal and the at least one biological feature.
