Abstract

A handheld computing device includes an electronic component assembly including at least one user interface component, and an enclosure formed from an extruded tube. The extruded tube defines an internal lumen between open ends, and has a substantially uniform cross section along a longitudinal axis thereof. The extruded tube includes a front face, a back face, side portions connecting the front face and the back face, at least one access opening provided on the front face, and a pair of guide rails formed in the lumen along the side portions in parallel with the longitudinal axis, the guide rails slidably guiding and receiving the electronic component assembly. The guide rails support the electronic component assembly and provide a reference surface for positioning the electronic component assembly relative to the front face such that the user interface is placed right behind the access opening to provide user access therethrough.

5. The method as recited in claim 2, wherein the second assembly further includes a frame for carrying the input device,

and wherein, in said inserting the second assembly, a bottom surface of the frame abuts the top surface of the internal rails.

6. The method as recited in claim 2, wherein the second assembly is inserted in a space between the pair of the internal rails above the bottom reference surface beneath the second access opening, while part of the first assembly is inserted in a space under the bottom reference surface beneath the second access opening.

7. The method as recited in claim 1, wherein the providing the enclosure formed from an extruded tube includes:

extruding a tube having the front face, a back face, and side portions connecting the front face and the back face, the pair of internal rails formed in the lumen along the side portions;

cutting the extruded tube to a desired length, forming a top open end and a bottom open end;

forming access openings on the front face of the extruded tube; and

forming a recessed area on a top surface of the extruded tube.

8. The method as recited in claim 7, wherein the electronic components include a first assembly having a display and a top plate, and wherein said assembling electronic components comprises:

inserting the first assembly into the lumen through the top open end of the extruded tube, the first assembly being positioned relative to the longitudinal axis by the top plate abutting the recessed area such that the display aligns with a first access opening.

9. The method as recited in claim 8, wherein the providing the enclosure formed from an extruded tube further includes:

removing a portion of the internal rails from the internal wall of the lumen in a vicinity of the bottom end the extruded tube;

forming slots on the internal wall of the lumen in the vicinity of the bottom open end; and

mounting a window in one of the access openings.

10. The method as recited in claim 9, wherein the electronic components further include a second assembly having an input device, and the window includes a flange having stop members, and wherein said assembling electronic components further comprises:

inserting the second assembly into the lumen through the bottom open end of the extruded tube, the second assembly being positioned relative to the longitudinal axis by abutting the stop members such that the input device aligns with a second access opening.

11. The method as recited in claim 10, wherein the second assembly further includes a tag, and wherein said assembling electronic components further comprises:
