Abstract: A background module includes a light-emitting element, a light guide plate, and a light shielding structure. The light guide plate includes a reflective material layer. The reflective material layer is disposed on a top surface of the light guide plate and located near the light-emitting element. After a light beam emitted by the light-emitting element is introduced into the light shielding structure, a portion of the light beam is reflected back into the light shielding structure by the reflective material layer. On the other hand, a portion of the light beam is transmitted through the reflective material layer and absorbed by the light shielding structure. Consequently, the possibility of causing light leakage will be minimized.

Abstract: A touch pen includes a sleeve, a contact element, a sensing device and a buffering element. The contact element is penetrated through the sleeve and movably relative to the sleeve. The sensing device is disposed within the sleeve. The buffering element is disposed within the sleeve. The contact element and the sensing device are separated from each other by the buffering element. While the contact element is moved in response to an external force applied to touch pen, the impact of the contact element on the sensing device is largely reduced because the contact element and the sensing device are separated from each other by the buffering element. Moreover, since the external force is received by the buffering element, the sensing device can be protected by the buffering element. Consequently, the failure probability of the touch pen is reduced.

Abstract: A touch device warning method and a touch device warning system are provided. The touch device warning method provides multiple judgment mechanisms.

Once the conditions of the judgment mechanisms are satisfied, the touch device warning method warns the user of taking back the touch pen. Consequently, the possibility of losing the touch pen is reduced, and the occurrence of the erroneous judgment is avoided.

Abstract: A keyboard includes plural keys, a base plate and a backlight module. Each key includes a keycap and a sliding element. The keycap includes a first protrusion part. The sliding element includes a second protrusion part. The first protrusion part has a first slant surface. The second protrusion part has a second slant surface.

Consequently, a light beam transmitted through the base plate is further transmitted through the sliding element and outputted from the keycap, or the light beam transmitted through the base plate is blocked by the sliding element.

Abstract: A buzz detecting method and a buzz detecting system are provided for testing whether an under-test sound playing device generates a buzz while playing sound. By an application program module, plural under-test sound signals from the under-test sound playing device are converted into plural under-test frequency-domain signals corresponding to the under-test sound signals through Fourier transform. Moreover, the application program module calculates plural under-test noise ratios corresponding to the frequencies of respective under-test sound signals according to respective under-test frequency-domain signals. After the plural under-test noise ratios are compared with plural standard noise ratios from a standard sound playing device, the application program module may automatically judge whether the under-test sound playing device generates a buzz while playing sound. Since the testing procedure does not need to be implemented by the trained testers, the overall efficiency is largely enhanced.
