Abstract

A plug-in module adds functionality to a portable electronic device. The module includes a housing that is accepted by a housing port of the portable electronic device. The module includes at least one latch to secure the module to the electronic device. Each latch includes a first member, a second member, and a third member. The housing includes at least one receptacle corresponding to each latch. The receptacles are sized and positioned to accept a member of the latch and direct the latch to a groove located on the portable electronic device. Optionally, the latch includes a slip-resistant surface sized to accept a human finger or thumb. The module also preferably includes a hardware interface connector sized and positioned within the housing to engage a 120-pin hardware interface port on the portable electronic device when the module housing is positioned on the housing port of the portable electronic device. Receptacles of the electric connector have certain functionality corresponding to the pins on the port.

Claims

1-11. -11. (canceled)

12. A portable electronic device for use in servicing a vehicle, comprising:

a handheld computing device having a device housing and device electronic components;

a module having a module housing and module electronic components, wherein the module housing is constructed and arranged to couple with the device housing, and wherein the module electronic components communicate with the device electronic components when the module housing is coupled with the device housing; and

a cartridge having a cartridge housing and cartridge electronic components, wherein the cartridge housing is constructed and arranged to couple with the module housing, and wherein the cartridge electronic components communicate with the module electronic components and the device electronic components when the cartridge housing is coupled with the module housing and the module housing is coupled with the device housing;

wherein said module provides additional functionality to said handheld computing device; and

wherein said cartridge provides additional functionality to said module.

13. The apparatus of claim 12, wherein said module housing includes at least one latch for securing the module housing to the device housing.

14. The apparatus of claim 13, wherein the device housing includes at least one receptacle to receive the at least one latch.

15. The apparatus of claim 13, wherein the at least one latch has a first member, a second member, and a third member, each of the members having a first end and a second end, wherein the first end of the first member is connected to the first end of the second member such that the first member and the second member form an angle of between 60 degrees and 130 degrees, and wherein the second end of the first member is connected to the first end of the third member such that the first member and the third member form an angle of between 60 degrees and 130 degrees.

16. The apparatus of claim 13, wherein the at least one latch includes a locking finger constructed and arranged to flexibly mate with a formation located on an interior side surface of the device housing.

17. The apparatus of claim 13, wherein the at least one latch includes a slip-resistant surface, sized to accept a human finger or thumb.

18. The apparatus of claim 13, wherein the at least one latch includes a first formation substantially at a point where a first member of the at least one latch connects to a second member of the at least one latch;

and wherein the first formation of the at least one latch is constructed and arranged to engage a second formation located on a surface of the device housing.

19. The apparatus of claim 12, wherein the cartridge electronic components include a computer processor.

20. The apparatus of claim 12, wherein the cartridge electronic components include a computer memory.

21. The apparatus of claim 12, wherein the module electronic components include a computer processor.

22. The apparatus of claim 12, wherein the module electronic components include a computer memory.

23. A method to increase functionality of a portable electronic device that services a vehicle, comprising:

providing a handheld computing device having device electronic components;

increasing the functionality of the computing device by coupling the computing device to a module having module electronic components; and

increasing the functionality of the module by coupling the module to a cartridge having cartridge electronic components,

wherein the cartridge, module, device electronic components can communicate with each other.

24. A means for servicing a vehicle using a portable electronic device, comprising:

a means for handheld computing having a housing means and an electronic means;

a means for providing primary modular functionality having a housing means and an electronic means, wherein the housing means of the means for providing primary modular functionality is designed to couple with the housing means of the means for handheld computing, wherein the electronic means of the means for providing primary modular functionality communicates with the electronic means of the means for handheld computing when the housing means of the means for providing primary modular functionality is coupled with the housing means of the means for handheld computing; and

a means for providing secondary modular functionality having a housing means and an electronic means, wherein the housing means of the means for providing secondary modular functionality is designed to couple with the housing means of the means for providing primary modular functionality, and wherein the electronic means of the means for providing secondary modular functionality communicates with the electronic means of the means for providing primary modular functionality and the electronic means of the means for handheld computing when the housing means of the means for providing secondary modular functionality is coupled with the housing means of the means for providing primary modular functionality and the means for providing primary modular functionality is coupled to the means for handheld computing;

wherein the means for providing primary modular functionality provides additional functionality to the means for handheld computing; and

wherein the means for providing secondary modular functionality provides additional functionality to the means for providing primary modular functionality.

25. The apparatus of claim 24, wherein the housing means of the means for providing primary modular functionality includes means for securing the housing means of the means for providing primary modular functionality to the housing means of the means for handheld computing.

26. The apparatus of claim 25, wherein the housing means of the means for handheld computing includes means for receiving the means for securing.

27. The apparatus of claim 25, wherein the means for securing has a first member, a second member, and a third member, each of the members having a first end and a second end, and wherein the first end of the first member is connected to the first end of the second member such that the first member and the second member form an angle of between 60 degrees and 130 degrees, and wherein the second end of the first member is connected to the first end of the third member such that the first member and the third member form an angle of between 60 degrees and 130 degrees.

28. The apparatus of claim 25, wherein the means for securing includes means for mating constructed and arranged to flexibly mate with means for mating located on an interior side surface of the housing means of the means for handheld computing.
