Abstract: A touch pen controls a capacitive touch screen and an electronic device. The electronic device includes a first wireless transmission module. The touch pen includes a pen tip, a second wireless transmission module, a G-sensor, and a pressure sensor. The pen tip is interacted with the capacitive touch screen. The second wireless transmission module is in communication with the first wireless transmission module. According to an angle change of the touch pen sensed by the G-sensor, a first control signal is transmitted from the second wireless transmission module to the first wireless transmission module to control the electronic device. According to a pressure exerted on the pen tip and sensed by the pressure sensor, a second control signal is transmitted from the second wireless transmission module to the first wireless transmission module or the capacitive touch screen to control the first wireless transmission module or the capacitive touch screen.

Abstract: A mouse device includes a grip part, an extension part, an infrared light sensing unit, and a controlling unit. The extension part is extended from the grip part for supporting a wrist of a user. The infrared light sensing unit includes an infrared light source and an image sensor. The infrared light source emits an infrared light beam. A portion of the infrared light beam within a specified wavelength range is absorbed by the plural blood vessels of the wrist. Another portion of the infrared light beam beyond the specified wavelength range is reflected from the plural blood vessels to the image sensor, so that plural infrared images are generated. The controlling unit calculates a blood flow rate of the plural blood vessels of the wrist according to the plural infrared images, and acquires the body information of the user according to the blood flow rate.

Abstract: A gesture input device includes an operating plate, a first infrared light sensing unit, a second infrared light sensing unit, and a controlling unit. Each of the first infrared light sensing unit and the second infrared light sensing unit includes an infrared light source and an image sensor. A first portion of the infrared light beam within a specified wavelength range is absorbed by the plural blood vessels of the finger, and a second portion of the infrared light beam beyond the specified wavelength range is reflected from the plural blood vessels. According to plural infrared images generated by the first infrared light sensing unit and the second infrared light sensing unit, the controlling unit generates a displacement information corresponding to the movement of the finger in order to control the computer.

Abstract: A switch triggering device of an electronic device is provided. By the switch triggering device, a switch on a top surface of a circuit board can be controlled from a bottom side of the electronic device. The switch triggering device includes a first linkage element, a second linkage element and a third linkage element, which are arranged between an upper cover and a base of the electronic device. The second linkage element is pivotally coupled to the upper cover. The two ends of the second linkage element are pivotally coupled to the first linkage element and the third linkage element, respectively. When the first linkage element is pressed from the base and moved toward the upper cover, the second linkage element is rotated relative to the upper cover. Consequently, the third linkage element is correspondingly moved toward the switch so as to trigger the switch.

Abstract: A cursor control system includes a cursor control device and a computer host. The cursor control device includes an operating plate, a blood vessel sensing unit, and a controlling unit. The operating plate is used for placing a palm and a finger of a user thereon. The blood vessel sensing unit is used for detecting the finger at different positions, thereby acquiring plural blood vessel images of the finger. According to the plural blood vessel images, a finger displacement amount is acquired by the controlling unit. In addition, a cursor moving signal corresponding to the finger displacement amount is transmitted from the controlling unit to the computer host. According to the cursor moving signal, the cursor is correspondingly moved.

Abstract: An airflow-sensing computer cursor generator includes a microprocessor and plural air flow rate sensors. The plural air flow rate sensors are used for sensing airflow rates resulted from a moving action of an inductor in plural directions, thereby generating respective air flow rate signals corresponding to the plural directions. The microprocessor is used for judging a moving direction and a displacement value of the inductor according to the air flow rate signals, thereby generating a computer cursor signal.
