Patent ID: 8284549

Claim:
An inverted U-shaped frame, comprising: a coupling at either end of the inverted U-shaped frame for pivotably securing to front corners of an electronic device; a micro-projector pivotably mounted on a transverse part of the inverted U-shaped frame; and a camera pivotably mounted on the transverse part of the inverted U-shaped frame besides the micro-projector; wherein either coupling comprises a hollow cylindrical projection projecting toward the other coupling, the projection including a toothed outer surface and an axial conductive hole electrically connected to both the micro-projector and the camera; and wherein the electronic device is a laptop comprising a joint at either one of two front corners, the joint including a cylindrical aperture having a toothed inner surface and an axial conductive shaft, and wherein the couplings are adapted to pivotably secure to the joints by inserting the projections into the apertures with the holes fitted on the shafts and the toothed outer surfaces being in pivotal tooth engagement with the toothed inner surfaces so that an electrical connection from the laptop to both the micro-projector and the camera and a signal communication between the laptop and each of the micro-projector and the camera are carried out.
