Abstract

In the present invention, a device for transmitting a pairing request information is provided. The device includes a memory having a field to store a pairing acknowledgement information, a transceiver, and a processor electrically connected to the memory and the transceiver. The processor is configured to determine whether the field is in one of conditions as follows: (1) the field is empty, (2) the field stores an information not being the pairing acknowledgement information, and (3) the field stores the pairing acknowledgement information that is not valid for the processor. The processor automatically drives the transceiver to transmit the pairing request information if the field is in the one condition.

Abstract

The present invention discloses a method to manufacture a keycap for keys of a keyboard, including: providing a top fabric layer and a molding film disposed beneath the top fabric layer; molding the molding film and the top fabric layer to form a film structure having an inner surface; and providing a keycap body having an upper surface, wherein the outline of the upper surface matches with that of the inner surface to form the keycap. In the present invention, the keycap is formed using the film structure and the keycap body by plastic injection or adhesion agent, the keycap is further manufactured as keys, and a symbol is engraved on the upper surface of the film structure by laser. Because the backlit device's light transmits through the keycap, users can recognize the symbols on the keys.
