Abstract: A computer system includes a host, a bracket and a projector. The host includes a holding portion, and the holding portion defines a first space. The bracket is secured to the host and defines a second space. The projector is electrically connected to the host, and rotatable relative to the first space and the second space.

Abstract: An electronic device includes a base, a restricting piece, a coiling piece, and a cable. The base defines a containing space. The restricting piece is secured in the containing space. The restricting piece includes a pivot and a cable outlet. The coiling piece includes a coiling post. A side of the coiling post defines a pivot hole which receives the pivot of the restricting piece inserted therein to pivotally mount the coiling piece in the containing space. The cable is wrapped on the coiling post, and a part of the cable is inserted through the cable cutout.

Abstract: A power plug is configured for connecting a power adaptor to a power supply socket. The power plug includes a first portion and a second portion. At least two prongs are disposed on the first portion and are capable of being coupled to the power supply socket. The second portion is configured to be electrically coupled to the power adaptor. The second portion defines a receiving housing capable of accommodating the power adaptor.

Abstract: A computer system includes a chassis, a keyboard, a light-emitting member, a light-guiding member, and a control system. The keyboard is attached to the chassis. The light-emitting member is disposed in the chassis and capable of emitting light. The light-guiding member directs light of the light-emitting member to irradiate on the keyboard. The control system is electronically coupled to the light-emitting member to control light brightness of the light-emitting member.

Abstract: An apparatus includes an electronic device. The electronic device includes a cursor controlling apparatus which is detachably mounted to the electronic device. The cursor controlling apparatus includes a touchpad mounted on a top portion of the cursor controlling apparatus, a mouse module mounted in the cursor controlling apparatus, and a controller connected to the touchpad and the mouse module. The controller is capable of detecting whether the cursor controlling apparatus is mounted to the electronic device. The controller enables the touchpad and disables the mouse module when the controller detects the cursor controlling apparatus is mounted to the electronic device. The controller enables the mouse module and disables the touchpad when the controller detects the cursor controlling apparatus is not mounted to the electronic device.

Abstract: A fastening apparatus is provided to secure a first component to a second component. The fastening apparatus includes a fastening anchor and a securing member. The fastening anchor includes two separated securing parts defining internal screw thread and external screw thread. The securing member defines external screw thread. The securing member is accommodated into the fastening anchor by the securing member external screw thread engaging the fastening anchor internal screw thread, and the two separated securing parts of the fastening anchor is urged to expand outward to engage with one of the first component and the second component.

Abstract: A keyboard includes a base and a cover. The base receives a main circuit board therein, and the cover receives a flexible circuit board therein. The flexible circuit board is electrically coupled to the main circuit board and comprises of a plurality of touch areas located thereon. Each touch area is capable of generating electrical signals in the flexible circuit board when touched. The electrical signals are capable of being transmitted to the main circuit board. A plurality of key areas is integrated on the cover respectively corresponding to the touch areas. Each of the key areas is resiliently deformable and capable of touching the corresponding touch area.
