Abstract: An electronic device includes a shell, a circuit board, a triggering element, a light-transmissive button and an optical sensor. The shell defines a button hole in an edge thereof and forms a receiving space therein. The circuit board module is installed in the receiving space. The triggering element is fixed on and electronically connected with the circuit board module. The light-transmissive button is received in the button hole, and is depressible for turning on and off the triggering element. The optical sensor is positioned beneath the light-transmissive button for detecting intensity of the ambient light passing through the light-transmissive button. The appearance of the electronic device is not affected by the optical sensor.

Abstract: An electrical adapter assembly for connecting a first hard disk drive and a second hard disk drive is provided. The electrical adapter assembly includes a connector capable of electrically inserting into the first hard disk drive, a printed circuit board (PCB) module electrically connecting the connector, and a loading member for loading the first hard disk drive. The PCB module includes a chip for controlling data transfer between the first hard disk drive and the second hard disk drive. The loading member includes a base and at least two guiding portions pivotally attached on the base to allow the first hard disk drive to be able to slide between the at least two guiding portions.

Abstract: A keyboard includes a main body disposed with a plurality of keys and an integrated member. The integrated member is detachably connected to the main body. The integrated member is capable of being moved with respect to the main body between a first position where the integrated member and the main body forms a substantially flat surface and a second position where the integrated member is capable of being activated to receive audio inputs.
