## Abstract

The locations of electronic devices in an institutional facility are determined based on interaction with the wireless mobile devices of users who roam though the facility and interact with (or are detected by) the devices.

## Claims

### Claim at position 1

-12. (canceled)

### Claim 13

A movable electronic device configured for interaction with users, the movable electronic device comprising:
a wireless interface for interaction with portable wireless mobile devices of users;
an input device for receiving input from the users;
a processor; and
a computer memory storing agent instructions for execution by the processor, the agent instructions, when executed, causing the movable electronic device to:
authenticating a user for access to restricted data consistent with a security policy and a privilege level of the user, via an authentication sequence comprising (i) obtaining an authentication credential of the user, via the wireless interface, from a portable wireless mobile device of the user, (ii) verifying the authentication credential, and (iii) granting access, for the user, to the restricted data when the authentication credential is verified, and
during or after the authentication, (a) interrogating the portable wireless device of the user, via the wireless interface, for local GPS coordinates of the portable wireless mobile device, and (b) registering the local GPS coordinates as a location of the movable electronic device.

### Claim 14 (depends on 13)

The device of claim 13, wherein registering the local GPS coordinates comprises electronically communicating the local GPS coordinates to a location server as the location of the movable electronic device.

### Claim 15 (depends on 13)

The device of claim 13, wherein the computer memory stores an update interval for the movable electronic device, the agent instructions being configured to only interrogate the portable wireless device for local GPS coordinates if an elapsed time since an immediately preceding location update for the movable electronic device exceeds the update interval.

### Claim 16 (depends on 15)

The device of claim 15, wherein the update interval corresponds to an adaptive time period based on a frequency with which the location of the movable electronic device changes.

### Claim 17 (depends on 15)

The device of claim 15, wherein the update interval corresponds to a fixed amount of time.

### Claim 18 (depends on 13)

The device of claim 13, wherein the authentication credential comprises a biometric indicium.

### Claim 19 (depends on 13)

The device of claim 13, wherein the wireless interface implements a short-range wireless protocol, thereby ensuring co-location of the portable wireless mobile device and the movable electronic device.

### Claim 20 (depends on 13)

The device of claim 13, wherein the movable electronic device is configured to wake up when the portable wireless mobile device enters a communication range of the movable electronic device.

### Claim 21 (depends on 20)

The device of claim 20, wherein the communication range is an NFC range.

### Claim 22 (depends on 13)

The device of claim 13, further comprising a display.

### Claim 23 (depends on 13)

The device of claim 13, wherein the movable electronic device is incapable of receiving GPS signals.

### Claim 24 (depends on 23)

The device of claim 23, wherein the movable electronic device lacks a GPS chipset.

### Claim 25 (depends on 13)

The device of claim 13, wherein the agent instructions cause the movable electronic device to authenticate the user upon occurrence of a proximity event.

### Claim 26 (depends on 25)

The device of claim 25, wherein the proximity event occurs when the portable wireless mobile device is moved into proximity to the movable electronic device.

### Claim 27

A method of tracking and updating the location of a movable electronic device that includes a wireless interface for interaction with portable wireless mobile devices of users, the method comprising:
establishing an update interval for the movable electronic device; and
only when the update interval has elapsed, (i) opportunistically interrogating a portable wireless device of a user, via the wireless interface, for local GPS coordinates of the portable wireless mobile device only upon occurrence of a proximity event when the portable wireless mobile device is moved into proximity with the mobile electronic device, and (ii) electronically communicating the local GPS coordinates to a location server as a location of the movable electronic device.

### Claim 28 (depends on 27)

The method of claim 27, wherein the portable wireless device is interrogated for the local GPS coordinates only when instructions to do so have been received by the movable electronic device.

### Claim 29 (depends on 28)

The method of claim 28, wherein the instructions are received from the location server.

### Claim 30 (depends on 27)

The method of claim 27, wherein the update interval corresponds to a fixed amount of time.

### Claim 31 (depends on 27)

The method of claim 27, wherein the update interval corresponds to an adaptive time period based on a frequency with which the location of the movable electronic device changes.

### Claim 32 (depends on 27)

The method of claim 27, wherein the wireless interface implements a short-range wireless protocol, thereby ensuring co-location of the portable wireless mobile device and the movable electronic device.

### Claim 33 (depends on 27)

The method of claim 27, wherein the movable electronic device is configured to wake up when the portable wireless mobile device enters a communication range of the movable electronic device.

### Claim 34 (depends on 33)

The method of claim 33, wherein the communication range is an NFC range.

### Claim 35 (depends on 27)

The method of claim 27, wherein the movable electronic device comprises a display.

### Claim 36 (depends on 27)

The method of claim 27, wherein the movable electronic device is incapable of receiving GPS signals.

### Claim 37 (depends on 36)

The method of claim 36, wherein the movable electronic device lacks a GPS chipset.
