Abstract

A technique for controlling lockable devices includes a key device wirelessly transmitting a first request to a server apparatus. The server apparatus receives the first request and proceeds to identify a controllable lock whose location the server apparatus has measured to be within a physical space mapped by the server apparatus, causing the identified controllable lock to emit a human-detectable indication. In response to an action by a user, the key device wirelessly transmits a second request that directs the server apparatus to toggle a lock state of the identified controllable lock, such as to lock the controllable lock or to unlock it.

Claims

1. A method of electronically controlling lockable devices, the method comprising:

wirelessly transmitting a first request from a key device to a server apparatus;

identifying, by the server apparatus in response to receiving the first request, a controllable lock whose location the server apparatus has measured to be within a physical space mapped by the server apparatus;

directing, by the server apparatus, the controllable lock to issue a human-detectable indication that the controllable lock has been selected for operation; and

in response to the key device receiving user input from a human user after the controllable lock has issued the human-detectable indication, wirelessly transmitting a second request from the key device to the server apparatus, the second request directing the server apparatus to toggle a lock state of the controllable lock.

2. The method of claim 1, further comprising;

measuring, by the server apparatus, a physical location of the key device relative to the physical space,

wherein identifying the controllable lock includes selecting, by the server apparatus, the controllable lock from among multiple controllable locks in the physical space based at least in part on a location of the key device and respective locations of the multiple controllable locks.

3. The method of claim 2, wherein wirelessly transmitting the second request from the key device to the server apparatus is performed after:

the server apparatus has directed a first candidate lock of the multiple controllable locks in the physical space to issue a human-detectable indication; and

in response to a user action, the key device has wirelessly transmitted a request to indicate a next candidate lock of the multiple controllable locks.

4. The method of claim 2,

wherein the key device further includes an orientation sensor,

wherein the first request includes an orientation measurement made by the orientation sensor, the orientation measurement indicating a direction which the key device is pointing, and

wherein selecting, by the server apparatus, the controllable lock is further based on the orientation measurement.

5. The method of claim 4,

wherein identifying the physical location of the key device is performed by sensing a wireless packet emitted by the key device using a location positioning service that includes multiple antenna units.

6. The method of claim 2, wherein the server apparatus stores a map of the physical space, and wherein selecting, by the server apparatus, the controllable lock is further based on the map of the physical space indicating that the key device has an unobstructed view of the controllable lock.

7. The method of claim 1,

wherein, prior to transmitting the first request, the method further comprises performing, by the key device, a biometric test of the user of the key device to confirm an identity of the user, and

wherein the key device is configured to transmit the first request in response to the biometric test succeeding and to prevent transmission of the first request in response to the biometric test not succeeding.

8. The method of claim 7, wherein performing the biometric test includes operating a thumbprint sensor in the key device.

9. The method of claim 8, wherein the thumbprint sensor is incorporated in a button of the key device, and wherein transmitting the first request is performed in response to (i) the user pushing the button and (ii) the key device successfully authenticating the user using the thumbprint sensor.

10. The method of claim 9, further comprising, in response to the user pushing the button on the key device when the key device is disposed in a second physical space mapped by a second server apparatus, providing identifying information about the user to an element in the second physical location by:

(i) the key device wirelessly sending a user identifier of the user to the second server apparatus,

(ii) the second server apparatus contacting the server apparatus to request the identifying information about the user,

(iii) the server apparatus providing the identifying information about the user to the second server apparatus, and

(iv) the second server apparatus providing the identifying information about the user to the element in the second physical space.

11. The method of claim 2, further comprising operating the key device to unlock a second controllable lock, the key device establishing a first point-to-point session with the second controllable lock, the second controllable lock establishing a second point-to-point session with the server apparatus, the server apparatus directing the second controllable lock to unlock in response to exchanging authentication content over the first point-to-point session and the second point-to-point session.

12. The method of claim 11 wherein, when operating the key device to unlock the second controllable lock, the key device is disposed outside the mapped physical space.

13. The method of claim 11, wherein the server apparatus is a mobile server apparatus disposed within an automobile.

14. The method of claim 11, wherein the key device is a portable device having a portable power source, and wherein the method further comprises:

the key device assuming an inactive state; and

the key device transitioning from the inactive state to an active state in response to the key device receiving wireless energy emitted by the second controllable lock,

wherein the server apparatus directing the second controllable lock to unlock is performed automatically in response to the key device transitioning from the inactive state to the active state.

15. The method of claim 2, further comprising operating the key device to unlock a third controllable lock, the key device effecting unlocking of the third controllable lock by (i) making physical contact with the third controllable lock and (ii) while making physical contact, sending a shared secret to the third controllable lock over an optical connection.

16. The method of claim 15, wherein sending the shared secret over the optical connection is carried out in response to a user operation performed on the key device while the key device and the third controllable lock are making physical contact.

17. The method of claim 15, wherein the key device includes a contact interface having an infrared transceiver, and wherein the method further comprises:

with the contact interface of the key device placed against a contact interface of a second key device, exchanging, over the optical connection, identifying information about the user of the key device and a second user of the second key device to enable subsequent communication between the user and the second user.

18. The method of claim 2, wherein the key device is a portable device having a portable power source, and wherein the method further comprises:

the key device assuming an inactive state; and

the key device transitioning from the inactive state to an active state in response to the key device receiving wireless energy emitted by the controllable lock.

19. The method of claim 18, wherein transmitting the first request is performed automatically by the key device upon transitioning from the inactive state to the active state.

20. An electronic key device, comprising:

a body;

a user control in the body; and

control circuitry including a set of processors and memory, the control circuitry constructed and arranged to;

wirelessly transmit, in response to a first operation of the user control, a first request to a server apparatus, the first request directing the server apparatus to identify a controllable lock whose location the server apparatus has measured to be within a physical space mapped by the server apparatus; and

in response to a second operation of the user control, wirelessly transmit a second request from the key device to the server apparatus, the second request directing the server apparatus to toggle a lock state of the controllable lock identified in response to the first operation of the user control.
