Abstract: An icon display module includes a light blocking structure, a first light-emitting element, a second light-emitting element, a first light-guiding pattern structure and a second light-guiding pattern structure. The light blocking structure includes an accommodation space and a first light-blocking part. The accommodation space is divided into a first region and a second region by the first light-blocking part. When the first light-emitting element emits a first light beam, the first light beam is guided by the first light-guiding pattern structure and the second light-guiding pattern structure and projected on the target. Consequently, a first icon and a second icon are shown on the target. When the second light-emitting element emits a second light beam, the second light beam is guided by the first light-guiding pattern structure and projected to the target. Consequently, the first icon is shown on the target.

Abstract: A control device is connected with a microphone and a display device. The control device can be used to implement a microphone gain setting process. The control device includes an adjustment knob. When the adjustment knob of the control device is pressed down, the control device starts to implement the microphone gain setting process. At the same time, a message is shown on the display device to prompt that the control device starts to implement the microphone gain setting process and prompt the user to emit a sound to the microphone for a time period. Consequently, the sound is amplified by a signal gain amplifier of the control device. Then, a message is shown on the display device to prompt the user that the microphone gain setting process is completed.

Abstract: A 3D image sensing device includes a first camera lens, a second camera lens and a light source. A 3D image processing method for the 3D image sensing device includes the following steps. Firstly, a target is photographed by the first camera lens and the second camera lens, and the obtained images are processed in a stereo vision mode. Consequently, a first depth map is obtained. After the light source emits plural feature points to the target, the target is photographed by the first camera lens and the second camera lens, and the obtained images are processed in an active stereo vision mode. Consequently, a second depth map is obtained. The first depth map and the second depth map are synthesized as a synthesized depth map according to a synthetization strategy.

Abstract: A force touch judgement method is applied to a force touch pad with two force sensors. Firstly, a force touch operation corresponding to a real force value is performed on a force touch position. Then, a first sensing signal value and a second sensing signal value corresponding to the force touch operation are respectively generated by the two force sensors. Then, the first sensing signal value and the second sensing signal value are added as a total sensing signal value. A calibration force value corresponding to the force touch position is obtained. A first calibration signal value and a second calibration signal value corresponding to the force touch position are added as a total calibration signal value. A ratio of the total sensing signal value to the total calibration signal value is equal to a ratio of the real force value to the calibration force value.

Abstract: A composite function keyboard circuit includes a first matrix circuit, a first bias resistor group, a second matrix circuit, a second bias resistor group and a controller. Each switch unit in the first matrix circuit is an ink-type force sensing switch. A resistance of the ink-type force sensing switch is variable according to a pressing mode of a keypress action. An electrical connection path is formed between the ink-type force sensing switch and the corresponding bias resistor of the second bias resistor group. When the ink-type force sensing switch is electrically conducted, a divided sensing voltage is generated by the electrical connection path, and the controller generates a corresponding key control instruction according to a level of the divided sensing voltage. Furthermore, the cooperation of the first matrix circuit and the first bias resistor group can achieve a ghost key preventing function.
