Abstract: A gear position detection device for detecting a gear having multiple fingers is provided. The detection device includes a substrate, a control chip, and a drive line, a sense line, a first drive electrode, a second drive electrode, a first sense electrode and a second sense electrode formed on the substrate. The first and second drive electrodes are connected to the drive line to receive a drive signal. The first and second sense electrodes form induced electric field respectively with the first and second drive electrodes, and respectively output a first detected signal and a second detected signal via the sense line. The control chip outputs the drive signal via the drive line, receives the first and second detected signals via the sense line, calculate a differential signal between the first and second detected signals, and count a number of high levels of the differential signal to count a finger number.

Abstract: There is provided a capacitive joystick device including a substrate, a fixed plate, a movable member, a plurality of elastic elements, a cone and an operation stick. The substrate includes a ground region and a capacitance sensing region. The fixed plate includes a first opening. The movable member includes a second opening. The elastic elements are symmetrically disposed between the fixed plate and the movable member. The cone is disposed between the movable member and the substrate, and includes a base, a vertex and a lateral surface. The base presses against the movable member. The vertex is disposed on the ground region of the substrate. The lateral surface is aligned with the capacitance sensing region of the substrate. The operation stick extends from the base of the cone and passes through the first opening and the second opening.
