Abstract: An electronic device assembly includes a first electronic device and a second electronic device. The first electronic device includes a first wall body, a first opening, a sliding seat, a first magnetic attraction element, an elastic element and a connecting terminal. When the second wall body is close to the first wall body, the second magnetic attraction element and the first magnetic attraction element are magnetically attracted by each other. Consequently, the sliding seat is moved toward the first wall body, the elastic element is compressed, and the connecting terminal is protruded outside the first opening and contacted with the connector. When the second wall body is separated from the first wall body, the compressed elastic element is restored. Consequently, the sliding seat is moved away from the first wall body and the connecting terminal is retracted inside the first electronic device.

Abstract: An input device detection system includes a foundation, a cover plate and a trajectory detection plate. The foundation includes a base plate and plural first retractable rods. The base plate has a top surface, a bottom surface and a detection hole. The input device is pushed by the plural first retractable rods along a horizontal direction. The input device is pushed by plural second retractable rods of the cover plate along a vertical direction. The trajectory detection plate is located under the base plate. An optical sensing module of the input device emits a light beam. The light beam is transmitted through the detection hole and projected to the trajectory detection plate. When the trajectory detection plate is moved relative to the foundation and the light beam is reflected to the optical sensing module by the trajectory detection plate, a trajectory signal is generated.

Abstract: A vehicular projection system includes plural information collectors, a time-division multiplexing device and a projection mechanism. The plural information collectors are used for outputting driving information. The time-division multiplexing device includes plural wireless transmission modules. The time-division multiplexing device determines the transmitting sequence of plural information collectors according to the receiving sequence of wireless transmission requests from the plural information collectors. Moreover, the time-division multiplexing device determines the suitable wireless transmission modules according to the file properties of the driving information and the wireless transmission capabilities of the plural information collectors. Since the plural information collectors can simultaneously transmit driving information to the time-division multiplexing device through different wireless transmission modules, the wireless transmission efficiency is enhanced.

Abstract: A passive touch pen for a capacitive touch screen is provided. The passive touch pen includes a pen tube, a fixing post, and a conductive rubber tip. The pen tube has a vent. The fixing post is disposed within the pen tube, and includes a first perforation and a second perforation. The first perforation is open to a top surface of the fixing post. The second perforation is open to a lateral surface of the fixing post. The conductive rubber tip is sheathed around the fixing post and exposed outside the pen tube. After the conductive rubber tip is no longer compressed, air can be quickly introduced into to a vacant space between the conductive rubber tip and the top surface of the fixing post through the vent, the second perforation and the first perforation. Consequently, the conductive rubber tip is restored to an original non-compressed shape.
