1 is a schematic diagram of an embodiment of an electronic device having a biosensing device in accordance with the present invention. The electronic device includes sensing pads 11 and 12, a sensing circuit 13, a switching device 14, a power source 15, and a controller 16. The sensing pads 11 and 12 are disposed on a housing of the electronic device. The sensing circuit 13 is coupled to the sensing pads 11 and 12, and outputs a first signal S1 when the sensing pads 11 and 12 are short-circuited by a user's touch. The switching device 14 is coupled to the power source 15 and receives the first signal S1. The controller 16 is coupled to the switching device 14. When the switching device 14 is turned on when receiving the first signal S1, the controller 16 is powered by the power source 15.

In another embodiment, when the sensing pads 11 and 12 are short-circuited by a user touch, the logic level of the first signal S1 is pulled up from a logic low level to a logic high level.

When the switching device 14 is turned on because of the first signal S1, the controller 16 starts to receive power from the power source 15 to operate. The controller 16 now monitors the logic state of the first signal S1 in addition to maintaining the operation of the electronic device. When the controller 16 detects that the logic level of the first signal S1 changes and meets a predetermined condition (including but not limited to, the logic level of the first signal has changed for a predetermined time, or the bio-sensing occurs When the electronic device of the device is in an idle state, the controller 16 sends a second control signal S2 to the switching device 14 for turning off the switching device 14.

Specifically, when the controller 16 detects that the logic level of the first signal S1 is pulled from the logic high level to the logic low level, a timer within the controller 16 begins timing. When the controller 16 detects that the logic level of the first signal S1 is maintained When the time of the logic low level has exceeded a predetermined time, the controller 16 issues a second control signal S2 to the switching device 14 for turning off the switching device 14. Since the switching device 14 is turned off, the power source 15 also stops outputting power to the controller 16, and the controller 16 therefore stops operating.

It should be noted that the switching device 14 is controlled by the first signal S1 before being turned on, and is not turned off after being turned on because the logic level of the first signal S1 changes. The switching device 14 is only turned off by the second control signal S2 after being turned on. Therefore, the switching device 14 is controlled by the sensing circuit 13 in the off state, and the switching device 14 is controlled by the controller 16 in the on state.

In the present embodiment, the power of the sensing circuit 13 is provided by the power source 15. However, if the sensing pads 11 and 12 are not short-circuited by the user's touch, the sensing pads 11 and 12, the sensing circuit 13 and the power source 15 do not form a power loop, so the sensing circuit 13 does not consume power. Therefore, through the circuit design of the embodiment, as long as the sensing pads 11 and 12 are not short-circuited by the user's touch, the power consumption of the overall circuit is very low, and the power saving is achieved.

2 is a schematic view of another embodiment of an electronic device having a biosensing device in accordance with the present invention.

In another embodiment, when the sensing pads 21 and 22 are shorted due to a user touch, the logic level of the first signal S2 is pulled up from a logic low level to a logic high level.

When the switching device 24 is turned on because of the first signal S2, the control The device 26 begins to receive power from the second power source 25 to operate. The controller 26 now monitors the logic state of the first signal S2 in addition to maintaining the operation of the electronic device. When the controller 26 detects that the logic level of the first signal S2 is pulled from the logic high level to the logic low level, a timer within the controller 26 begins to time. When the controller 26 detects that the logic level of the first signal S2 is maintained at the logic low level for a predetermined time, the controller 26 sends a second control signal S2 to the switching device 24 for turning off the switching device. twenty four. Since the switching device 24 is turned off, the second power source 25 also stops outputting power to the controller 26, and the controller 26 therefore stops operating.

It should be noted that the switching device 24 is controlled by the first signal S2 before being turned on, and is not turned off after being turned on because the logic level of the first signal S2 changes. The switching device 24 is only turned off by the second control signal S2 after being turned on. Therefore, the switching device 24 is controlled by the sensing circuit 23 in the off state, and the switching device 24 is controlled by the controller 26 in the on state.

In the present embodiment, the power of the sensing circuit 23 is provided by the first power source 27, and other circuit components (including components not shown) are powered by the second power source 25. However, if the sensing pads 21 and 22 are not short-circuited by the user's touch, the sensing pads 21 and 22, the sensing circuit 23 and the first power source 25 do not form a power loop, so the sensing circuit 23 does not consume power. . At the same time, since the switching device 24 is in the off state, the switching device 24, the second power source 25, and the controller 26 also do not form a power circuit, and the second power source 25 does not output power. Therefore, through the circuit design of the embodiment, as long as the sensing pads 21 and 22 are not short-circuited by the user's touch, the power consumption of the overall circuit is very low, and the power saving is achieved.

Figure 3 is a schematic illustration of another embodiment of an electronic device having a biosensing device in accordance with the present invention. Compared with the electronic device shown in FIG. 2, in the present embodiment, the controller 36 is not directly connected to the second power source 35, but is connected to the second power source 35 through the switching device 34. In other words, the controller 36 can only be powered by the second power source 35 through the switching device 34 and cannot be directly powered by the second power source 35.

The electronic device includes sensing pads 31 and 32, a sensing circuit 33, a first power source 37, a switching device 34, a second power source 35, and a controller 36. The sensing pads 31 and 32 are disposed on a housing of the electronic device. The sensing circuit 33 is coupled to the sensing pads 31 and 32, and outputs a first signal S3 when the sensing pads 31 and 32 are short-circuited by a user touch. In another embodiment, when the sensing pads 31 and 32 are short-circuited by the user's touch, the logic level of the first signal S3 is pulled up from the logic low level to a logic high level.

When the switching device 34 is turned on because of the first signal S3, the controller 36 operates by receiving the power transmitted from the second power source 35 through the switching device 34. At this time, the controller 36 monitors the logic state of the first signal S3 in addition to the operation of the electronic device. When the controller 36 detects that the logic level of the first signal S3 is pulled from the logic high level to the logic low level, a timer in the controller 36 starts counting. When the controller 36 detects that the logic level of the first signal S3 is maintained at the logic low level for a predetermined time, the controller 36 sends a second control signal S3 to the switching device 34 for turning off the switching device. 34. Since the switching device 34 is turned off, the second power source 35 also stops outputting power to the controller 36, and the controller 36 therefore ceases to operate.

It should be noted that the switching device 34 is controlled by the first before being turned on. Signal S3, when turned on, will not be turned off due to the logic level change of the first signal S3. The switching device 34 is only turned off by the second control signal S3 after being turned on. Therefore, the switching device 34 is controlled by the sensing circuit 33 in the off state, and the switching device 34 is controlled by the controller 36 in the on state.

In the present embodiment, the power of the sensing circuit 33 is provided by the first power source 37, and other circuit components (including components not shown) are powered by the second power source 35. However, if the sensing pads 31 and 32 are not short-circuited by the user's touch, the sensing pads 31 and 32, the sensing circuit 33 and the first power source 35 do not form a power loop, so the sensing circuit 33 does not consume power. . Meanwhile, since the switching device 34 is in the off state, the switching device 34, the second power source 35, and the controller 36 do not form a power circuit, and the second power source 35 does not output power. Therefore, through the circuit design of the embodiment, as long as the sensing pads 31 and 32 are not short-circuited by the user's touch, the power consumption of the overall circuit is very low, and the power saving is achieved.

Figure 4 is a schematic illustration of an embodiment of an electronic device having a biosensing device in accordance with the present invention. The electronic device includes the sensing pads 41 and 42, the sensing circuit 43, the switching device 44, the power source 45, the controller 46, and the detecting circuit 47. The sensing pads 41 and 42 are disposed on a housing of the electronic device. The sensing circuit 43 is coupled to the sensing pads 41 and 42 and outputs a first signal S4 when the sensing pads 41 and 42 are short-circuited by a user's touch. In another embodiment, when the sensing pads 41 and 42 are shorted due to a user touch, the logic level of the first signal S4 is pulled up from the logic low level to a logic high level.

When the switching device 44 is turned on because of the first signal S4, the controller 46 starts to receive power from the power source 45 to operate. Controller 46 is now except In addition to maintaining the operation of the electronic device, the logic state of the first signal S4 is also monitored. When the controller 46 detects that the logic level of the first signal S4 is pulled from the logic high level to the logic low level, the controller 46 determines whether to turn off the switching device 44 according to the detection result of the detecting circuit 47. In this embodiment, the detecting circuit 47 is configured to detect whether the electronic device is in an idle state. When the controller 46 detects that the logic level of the first signal S4 is pulled from the logic high level to the logic low level and the electronic device is in an idle state, the controller 46 outputs the second control signal S2 to turn off the switching device 44. .

For example, if the electronic device is a mouse, the detecting circuit 47 detects whether the mouse has moved or whether a button is pressed to determine whether the electronic device is in an idle state. If the electronic device is a keyboard, the detecting circuit 47 detects whether a button on the keyboard is pressed to determine whether the electronic device is in an idle state. If the electronic device is a headset, the detection circuit 47 detects whether a sound source signal is transmitted to the earphone, and if not, the electronic device is judged to be in an idle state.

It is to be noted that the switching device 44 is controlled by the first signal S4 before being turned on, and is not turned off after the turn-on after the logic level change of the first signal S4. The switching device 44 is only turned off by the second control signal S2 after being turned on. Therefore, the switching device 44 is controlled by the sensing circuit 43 in the off state, and the switching device 44 is controlled by the controller 46 in the on state.

In the present embodiment, the power of the sensing circuit 43 is provided by the power source 45. However, if the sensing pads 41 and 42 are not short-circuited by the user's touch, the sensing pads 41 and 42, the sensing circuit 43 and the power source 45 do not form a power loop, so the sensing circuit 43 does not consume power. Therefore, through the circuit design of this embodiment As long as the sensing pads 41 and 42 are not short-circuited by the user's touch, the power consumption of the overall circuit is very low, and the purpose of power saving is achieved.
