Abstract: There is provided a cleaning robot including a light source module and an image sensor. The light source module projects a horizontal line pattern toward a moving direction. The image sensor captures, toward the moving direction, an image of the horizontal line pattern. The light source module is arranged below the image sensor so as to eliminate the interference from second reflection.

Abstract: A pressure sensing unit, a capacitive hybrid sensor device, and an input apparatus using the same are provided. The pressure sensing unit for detecting pressing events includes a pressure sensing pad group and a floating conductive element. The pressure sensing pad group includes a first pressure sensing pad, a second pressure sensing pad, and a ground pad that are spaced apart from one another. The first pressure sensing pad and the second pressure sensing pad are electrically shielded from each other by the ground pad. One of the floating conductive element and the pressure sensing pad group is configured to be movable in a movement direction relative to another one of the floating conductive element and the pressure sensing pad group. The floating conductive element overlaps with the pressure sensing pad group in the movement direction.

Abstract: A key unit and a keyboard using the same are provided. The key unit includes a circuit board, an elastic element, a keycap, and a processing circuit. The circuit board includes a capacitance sensing circuit embedded therein, and the capacitance sensing circuit includes a pair of sensor electrodes. The elastic element is disposed on the circuit board. The keycap is moveably disposed above and spaced apart from the circuit board. The elastic element is disposed between the keycap and the circuit board so that the keycap moves between a non-depressed position and a depressed position with respect to the circuit board. The processing circuit is electrically connected to the pair of sensor electrodes to obtain a variation of a coupling capacitance between the pair of sensor electrodes and to determine whether the keycap is touched or depressed according to the variation of coupling capacitance.

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.
