Abstract: The present invention relates to a cursor control system, including a first electronic device, a second electronic device, and a mouse. The mouse is wirelessly connected to the first electronic device and the second electronic device and may move a cursor on a first working desktop corresponding to the first electronic device or a second working desktop corresponding to the second electronic device. When receiving a drive signal from the mouse, the first electronic device displays a jump image on the first working desktop. When the cursor is moved to the jump image, the mouse may transmit a switching signal to the second electronic device according to a masking signal from the first electronic device, so that the second electronic device can display the cursor on the second working desktop.

Abstract: A luminous keyboard includes a key module, a light guide plate, a top-view light-emitting element and a light-shading element. The top-view light-emitting element emits a light beam. The light guide plate is located under the key module. The top-view light-emitting element is located under the light guide plate. A light-outputting surface of the top-view light-emitting element is contacted with the light guide plate. The light-shading element is disposed on the light guide plate for shading the light beam. A portion of the light-shading element is inserted into the light guide plate opening and formed as a reflective part in the light guide plate opening. After the light beam is projected on the reflective part and reflected by the reflective part, the light beam is transferred within the light guide plate and projected to the key module.

Abstract: A keyboard device includes a key, a base plate, a membrane circuit board and a buffering part. The membrane circuit board is disposed on the base plate. The key includes a keycap and a stabilizer bar. The stabilizer bar is connected between the keycap and the base plate. The stabilizer bar includes a main bar part, a first linking part and a first insertion part. The first linking part is connected between the main bar part and the first insertion part. The buffering part is disposed on the base plate or the membrane circuit board and located under the first linking part. While a keycap is moved downwardly relative to the base plate, the linking part of the stabilizer bar is contacted with the buffering part. The contact point between the linking part of the stabilizer bar and the buffering part is used as a fulcrum.

Abstract: The present invention relates to a fingerprint identifying module, including a circuit board, a fingerprint sensing component, a cover plate, and a waterproof sleeve. The fingerprint sensing component is disposed on the circuit board, and the cover plate covers the fingerprint sensing component. The waterproof sleeve partially covers the cover plate and the circuit board, so as to prevent a foreign liquid from entering a space between the fingerprint sensing component and the circuit board. The cover plate includes a cover plate body and an extending portion. The cover plate body covers the fingerprint sensing component. The extending portion surrounds the cover plate body, is located between the waterproof sleeve and the fingerprint sensing component, and may block the foreign liquid from passing.

Abstract: A control module includes a frame structure, a touchpad assembly and a hinge structure. The touchpad assembly is located over the frame structure. The hinge structure is arranged between the frame structure and the touchpad assembly. The hinge structure includes an elastic plate and a supporting element. An end of the elastic plate is connected with the touchpad assembly. The supporting element is disposed on frame structure and connected with the elastic plate. Due to the elastic plate, the touchpad assembly is swung is swung along a fixed direction. While the touchpad assembly is pressed down, the end of the elastic plate is correspondingly swung. Consequently, the touchpad assembly is swung stably, and the touch module is operated stably.

Abstract: A keyboard device includes a base plate with a base plate with a connecting bracket, a wing-type connecting element and a keycap. A first connecting shaft of the wing-type connecting element is inserted into the connecting bracket, so that the wing-type connecting element is connected with the base plate. While the keycap is depressed, the first connecting shaft is inserted into a first receiving space of the connecting shaft and used as a swinging fulcrum. Since the vertical movement of the wing-type connecting element is restricted by the first receiving space, the swinging range of the wing-type connecting element is reduced. Consequently, the keyboard device of the present invention is capable of improving the depressing stability of the keycap.
