Abstract: A module with a demoulding function comprises a module member including a cavity for molding a molded part, the module member having an upper channel and a lower channel passing therethrough, each of the upper and the lower channels having a ramp, and the ramps of the upper and lower channels extending symmetrically and convergently; two sliding members movably received in the upper and lower channels, respectively; and two cores each attached to one end of a respective said sliding member and located in the cavity. In use, after an injection molding process, the cores form recesses on the molded part. Then the two sliding members are pushed toward the molded part. The convergent ramps lead the two sliding members to converge, so that when the molded part is departed from the cavity, the cores come off from the recesses of the molded part.

Abstract: An image sensor module includes a circuit board (20), an image sensor (10) and a supporting board (30). The circuit board has a plurality of circuits formed thereon. The image sensor is arranged on one side of the circuit board and is electrically connected to the circuit board. The circuit board defines at least one through opening (22) therein. The supporting board is arranged on an opposite side of the circuit board. A protrusion (31) extends outwardly from the supporting board through the at least one through opening of the circuit board. The image sensor is mounted on the protrusion.

Abstract: An image sensor module includes a circuit board, an image sensor, and a supporting board. The image sensor is electrically connected to the circuit board. The circuit board defines a through opening therein. The supporting board is arranged on one side of the circuit board and includes a protrusion. The protrusion extends outwardly from the supporting board and includes a square-shaped block no larger than the image sensor. The square-shaped block passes through the through opening. The image sensor is mounted on the block and spaced from the circuit board.

Abstract: A cap assembly for a threadless bicycle headset is provided. The cap assembly includes a fastener and an outer cap integratedly combined with an exterior of the fastener. By the above structure, the integrated cap assembly has a simplified assembling process and improved stability over the prior art.

Abstract: A bicycle clipless pedal with a clamping force adjusting assembly is disclosed. The clamping force adjusting assembly allows a user to manually change a preload of a compression spring in the pedal so as to adjust a clamping force provided by a rear clamping set of the bicycle clipless pedal to a shoe cleat.
