Abstract: A detachable multi-functional ophthalmic tester is disclosed. The detachable multi-functional ophthalmic tester includes a movable platform and a measuring module. The movable platform has a first connecting portion and it can move along at least one direction. The measuring module is coupled to the first connecting portion. The measuring module is used to perform measurement on the eye to be tested. The movable platform and the measuring module are both detachable. The movable platform can move along X-axis direction, Y-axis direction and Z-axis direction. The first connecting portion of the movable platform can connect with different measuring modules to provide different functions. The measuring module can connect with different movable platforms.

Abstract: The present invention provides a disc drive and a flexible cable assembly therein. The disc drive includes a circuit board, a flexible cable assembly coupled to the circuit board, and an optical pick-up unit which the flexible cable assembly is electrically connected to. The flexible cable assembly includes a flexible cable and a protector partly attached to the flexible cable. When the optical pick-up unit processes the data on a disc, the protector keeps the flexible cable away from the disc.

Abstract: A plug detecting device comprises a circuit board, a signal processing unit, a connector, and a metal piece. The signal processing unit is installed on the circuit board. The connector is installed on the circuit board and electronically connected to the signal processing unit for connecting a plug having a metal outer ring with a first potential. The metal piece with a corresponding potential is electronically connected the signal processing unit and installed in the proximity of the connector. While the plug is plugged into the connector, the metal outer ring contacts the metal piece making the metal piece from the corresponding potential to the first potential, and that the signal processing unit confirms the plug has been plugged into the connector, so as to transmit or receive signals.
