ABSTRACT:
A portable personal computer, such as a notebook computer, is provided with an infrared (IR) port which is accessible to IR light signals sent toward the frontal face or aspect of the computer, where the data entry mechanism, such as a keyboard or touchpad, is located. The computer system may also include a conventional, rear mounted infrared light entry port, so that infrared communications may be made to the computer from several directions, such as both the front and rear of the computer. This overcomes the need for special cabling and a separate electronics board for extra IR interface electronics in the portable computer housing, where space is typically at a premium.
