Abstract

A variety of improvements to docking systems for portable computing devices are disclosed. For example, improved techniques for maintaining a data connection between a base portion of the docking system and a case portion of the docking system are disclosed. As an example, the docking system can include improved magnetics that help maintain the data connection between the base portion and the case portion, even during rotational movements of the case portion relative to the base portion. Further still, examples are described where the detection of a docking action between the case portion and the base portion can trigger any of a number of responsive actions.

First claim

What is claimed is:

1. A docking system comprising:
a case enclosure for receiving a portable computer, the case enclosure comprising (1) a first circuit, (2) a plurality of case enclosure contacts, and (3) a metallic element, the case enclosure contacts connected to the first circuit;
a base mount, the base mount comprising (1) a second circuit, (2) a plurality of angled resilient contact pins, and (3) a magnet, the angled resilient contact pins connected to the second circuit;
wherein the base mount is rotatable relative to an axis;
wherein the case enclosure is adapted to releasably dock with the base mount in a docked position, wherein the docked position includes a physical connection between the angled resilient contact pins and the case enclosure contacts to form an electrical connection between the first circuit and the second circuit;
wherein the first and second circuits are configured for data communication with each other through an interface that includes a data communication connection through the physical connection; and
wherein the docked position further includes a magnetic attraction between the magnet and the metallic element that holds the case enclosure in place with the base mount.

2. The system of claim 1 wherein the first and second circuits are configured for data communication with each other through the interface according to a protocol that does not guarantee data delivery.

3. The system of claim 1 wherein the magnetic attraction between the magnet and the metallic element restricts relative motion between the case enclosure and the base mount sufficient to prevent a loss of the data communication connection during operation.

4. The system of any of claim 1 wherein the case enclosure is adapted to releasably undock with the base mount in an undocked position, wherein the undocked position does not include a physical connection between the angled resilient contact pins and the case enclosure contacts; and
wherein the magnetic attraction is sufficient to require a force in a range from 5-20 kg force in an opposing direction that is normal to a user interface plane of the case enclosure to move the case enclosure to the undocked position.

5. The system of any of claim 1 wherein the magnetic attraction between the magnet and the metal member when the case enclosure is in the docked position restricts relative motion between the case enclosure and the base mount sufficient to prevent a loss of the data communication connection during operation and in the event of a force in a range of 1-5 kg being applied to the docked case enclosure in a rotational or tangential direction with respect to the axis.

6. The system of any of claim 1 wherein the magnetic attraction between the magnet and the metal member when the case enclosure is in the docked position restricts relative motion between the case enclosure and the base mount sufficient to prevent a loss of the data communication connection over the course of 50,000 rotations of the base mount.

7. The system of claim 1 wherein the angled resilient contact pins comprise a plurality of pogo pin contacts that extend from a surface of the base mount.

8. A docking system comprising:
a case enclosure for receiving a portable computer, the case enclosure comprising (1) a first circuit, and (2) a plurality of case enclosure contacts, the case enclosure contacts connected to the first circuit, and wherein the case enclosure contacts are located on a surface of the case enclosure;
a base mount, the base mount comprising (1) a circuit board, (2) a second circuit disposed on the circuit board, and (3) a plurality of resilient contact pins connected to the second circuit, wherein each of a plurality of the resilient contact pins extend from the circuit board at a cant angle that is off perpendicular from the circuit board; and
wherein the case enclosure is adapted to releasably dock with the base mount in a docked position, wherein the docked position includes a physical connection between the angled resilient contact pins and a plurality of the case enclosure contacts to form an electrical connection between the first circuit and the second circuit.

9. The system of claim 8 wherein the cant angles are in a range between 0.5 degrees and 10 degrees off perpendicular from the circuit board.

10. The system of claim 9 wherein the cant angles are in a range between 1 degree and 6 degrees off perpendicular from the circuit board.

11. The system of claim 9 wherein the cant angles are in a range between 2 degrees and 4 degrees off perpendicular from the circuit board.

12. The system of any of claim 8 wherein the base mount is rotatable relative to an axis.

13. The system of claim 12 wherein the first circuit is configured for data communication with the second circuit through an interface that includes a data communication connection through the physical connection.

14. The system of claim 13 wherein the first circuit is configured for data communication with the second circuit through the interface according to a protocol that does not guarantee data delivery.

15. A docking system comprising:
a base mount adapted to dock in a docked position with a case enclosure for a computing device, the base mount comprising a first circuit;
a stand adapted to support the base mount, the stand comprising a second circuit;
an arm that extends from the stand; and
a cable that runs through an interior portion of the arm and is adapted to electrically connect the first circuit with the second circuit;
a shuttle located inside the arm interior portion, the shuttle having an open interior, and wherein the cable runs axially through the open interior of the shuttle;
wherein the mount is physically connected to the arm;
wherein the mount is articulatable relative to the stand;
wherein the shuttle is adapted to slide within the arm interior portion in response to an articulation of the mount that imparts a force onto the cable; and
wherein the docked position includes a physical connection between the angled resilient contact pins and a plurality of case enclosure contacts of the case enclosure to form an electrical connection between the first circuit and the second circuit.

16. The system of claim 15 wherein the articulatable mount is rotatable about an axis.

17. The system of claim 16 further comprising another arm that extends from the stand, wherein the mount is also physically connected to the another arm, and wherein the axis extends from the arm to the another arm.

18. The system of any of claim 15 wherein the arm interior portion extends from a first arm opening to a second arm opening, wherein the cable includes a first cable end and a second cable end opposite the first cable end, wherein the first cable end extends from the first arm opening to connect with the first circuit, wherein the second cable end extends from the second arm opening to connect with the second circuit, and wherein the first arm opening is at an angle in a range between 60 degrees and 120 degrees relative to the second arm opening.

19. The system of any of claim 15 wherein the cable comprises a plurality of conductors, and wherein a plurality of the conductors are unbundled within the arm.

20. The system of claim 19 wherein the conductors include a sheathed cable that comprises a first data wire, a second data wire, and a shield wire, wherein the first data wire and the second data wire are arranged as a twisted pair, and wherein the sheathed cable is unbundled relative to the u
