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.

Claims

1. A personal computer system with infrared light communication capability, comprising:

a processor;

a data entry input mechanism for entry of data into said processor;

a housing containing said processor and having said data entry input mechanism mounted on a data entry surface thereof;

an infrared light sensor for receiving infrared communications for said processor;

an infrared receiving port coupled to said infrared light sensor and formed in said data entry surface of said housing for passage of infrared light to said infrared sensor; and

a light reflective mechanism moveable to selectively block and pass light between said infrared port and said infrared sensor.

2. The personal computer system of claim 1 wherein said light reflective mechanism comprises a light reflective surface which is reflective of infrared light.

3. The personal computer system of claim 2, wherein said light reflective surface comprises a mirror.

4. The personal computer system of claim 1, further including

said housing having a side wall;

and

an infrared port in said housing side wall for passage of infrared light to said infrared sensor.

5. The personal computer system of claim 4, wherein said light reflective mechanism selectively directs light entering said infrared port in said data entry surface and light entering said infrared port in said side wall onto said infrared sensor.

6. A personal computer system with infrared light communication capability, comprising:

a processor;

a data entry input mechanism for entry of data into said processor;

a housing containing said processor and having said data entry input mechanism mounted on a data entry surface thereof;

an infrared sensor for receiving infrared communications for said processor; and

an infrared port formed in said data entry surface of said housing for passage of infrared light to said infrared sensor;

said housing having a side wall;

an infrared port in said housing side wall for passage of infrared light to said infrared sensor; and

a light reflective mechanism moveable to selectively block and pass light between said infrared port and said infrared sensor.

7. The personal computer system of claim 6, wherein said personal computer system is a laptop computer.

8. The personal computer system of claim 6, wherein said personal computer system is a notebook computer.

9. The personal computer system of claim 6, wherein said data entry input mechanism comprises a keyboard.

10. The personal computer system of claim 6, further including:

said housing having a rear side wall; and

an infrared port in said housing rear side wall for passage of infrared light to said infrared sensor.

11. The personal computer system of claim 6 wherein said light reflective mechanism comprises a light reflective surface which is reflective of infrared light.

12. The personal computer system of claim 11, wherein said light reflective surface comprises a mirror.

13. The personal computer system of claim 6, wherein said light reflective mechanism selectively directs light entering said infrared port in said data entry surface and light entering said infrared port in said side wall onto said infrared sensor.
