2 Independent Claims

  • 1. A sensing device comprising: a cardiac impulse sensor for sensing a cardiac impulse of a human body physically spaced apart from the cardiac impulse sensor to generate an output signal; a control unit for periodically receiving the output signal of the cardiac impulse sensor, comparing the output signal with a threshold value, and generating a first operation signal of an electronic device, and transmitting the first operation signal to a processing unit; and the processing unit for processing and outputting the first operation signal to the electronic device according to the output signal of the cardiac impulse sensor, wherein the sensing device is configured to be capable of operating in a sleep mode where: if the sleep mode is set in the cardiac impulse sensor, the cardiac impulse sensor senses a base cardiac impulse; the base cardiac impulse is a cardiac impulse of the human body existing within a present sensing range of the cardiac impulse sensor at a time when the sleep mode is set; the control unit stores the output signal corresponding to the base cardiac impulse, sets the stored base cardiac impulse to a heart rate in a non-sleep state, and defines the base cardiac impulse as the threshold value used to determine a sleep state or a non-sleep state of the human body; the cardiac impulse sensor continues to sense a continuing cardiac impulse of the human body; and the control unit periodically compares the output signal corresponding to the continuing cardiac impulses to the threshold value and determines whether a difference between the output signal corresponding to the continuing cardiac impulse and the threshold value is within or greater than an error margin, determines whether a first reference time has elapsed after determination that the difference between the output signal corresponding to the continuing cardiac impulse and the threshold value is greater than the error margin, and generates the first operation signal if both the first reference time has elapsed and the difference between the output signal corresponding to the continuing cardiac impulse and the threshold value is greater than the error margin; wherein the control unit does not generate the first operation signal in the event that the first reference time does not elapse or the difference is within the error margin, wherein the control unit turns the processing unit on when the first operation signal is generated, wherein the cardiac impulse sensor is configured to be inserted into the electronic device, wherein the first operation signal directly controls the electronic device, and wherein control information of the first operation signal to the electronic device is wirelessly transmitted to a home gateway system and recorded.

  • 12. A method of controlling an electronic device, the method comprising: sensing a base cardiac impulse of a human body when a sleep mode is set in a cardiac impulse sensor, wherein the base cardiac impulse is a cardiac impulse of the human body existing within a present sensing range of the cardiac impulse sensor at a time when the sleep mode is set; storing an output signal corresponding to the base cardiac impulse as a threshold value to establish a non-sleep state heart rate; periodically sensing a continuing cardiac impulse of the human body within the present sensing range after the threshold value is stored; comparing an output signal corresponding to the continuing cardiac impulse to the threshold value; determining whether a difference between the output signal corresponding to the continuing cardiac impulse and the threshold value is within or greater than an error margin; determining whether a first reference time elapses upon determination that the difference between the output signal corresponding to the continuing cardiac impulse and the threshold value is greater than the error margin; and generating an operation signal if both the first reference time has elapsed and the difference between the output signal corresponding to the continuing cardiac impulse and the threshold value is greater than the error margin, wherein the operation signal is not generated when the first reference time does not elapse or the difference between the output signal corresponding to the continuing cardiac impulse and the threshold value is within the error margin, wherein the operation signal directly controls the electronic device, and wherein control information of the operation signal to the electronic device is wirelessly transmitted to a home gateway system and recorded.
