Abstract

In one aspect of the invention, a method for determining the location of a device is described. The method involves using one or more signal emitting platforms, which are capable of performing a wide variety of operations. In some embodiments, for example, the signal emitting platform is capable of physical movement. Various embodiments relate to signal emitting platforms, devices, systems, servers, computer code, methods and techniques for determining the location of a device.

causing adjusting a strength of the signal emitted from the particular one of the platforms;

detecting a change in strength between the first received signal data and the second received signal data caused at least in part by the movement of the particular one of the platforms;

based at least in part on the change in the strength of the received signal data, determining a location of the mobile device; and

transmitting a notification based at least in part on the determined location of the mobile device to the mobile device for displaying at a display of the mobile device.

2. The method of claim 1 further comprising causing changing a direction of a directional antenna on the particular one of the platforms.

3. The method of claim 1 further comprising causing changing a type of signal being emitted from the particular one of the platforms.

4. The method of claim 3 wherein the changing of the type of signal involves switching from a first type of signal to a second type of signal, the first and second types of signals being selected from the group consisting of Bluetooth, WiFi, FM radio, ultrasound and light.

5. The method of claim 1 further comprising causing selectively turning on or off an antenna on the particular one of the platforms.

6. The method of claim 1 further comprising causing the particular one of the platforms to move in a particular linear direction.

7. The method of claim 1 wherein during a time period in which the change in the strength of the received signal takes place, the mobile device remains stationary.

8. The method of claim 1, wherein the notification includes an advertisement.

9. The method of claim 8 wherein the determination of the location of the mobile device is performed without requiring fingerprinting wherein fingerprinting involves collecting signal strength data from a plurality of different locations before receipt of the first signal data from the mobile device.

10. A signal emitting platform of a plurality of signal emitting platforms that are arranged to help determine a location of a mobile device, the signal emitting platform comprising:

a signal emitting element, the signal emitting element arranged to emit a signal, when none of the other plurality of signal emitting platforms is emitting signal and in sequence with the other plurality of signal emitting platforms, that is received by the mobile device and used to determine a location of the mobile device so that a notification based at least in part on the determined location of the mobile device is transmitted to the mobile device for displaying at a display of the mobile device;

a movement element that helps physically move the signal emitting platform;

at least one processor; and

at least one memory, the memory including a non-transitory computer readable storage medium stored in a tangible form, the non-transitory computer readable storage medium including executable computer code that, when executed by the at least one processor, causes the signal emitting platform to;

receive a request to perform a first operation wherein the first operation involves using the movement element to move the signal emitting platform in a particular direction, thereby causing a change in the strength of the signal received by the mobile device, and

receive a request to perform a second operation wherein the second operation further involves using the signal emitting element to adjust a strength of the signal.

11. The signal emitting platform of claim 10 wherein the movement element involves one selected from the group consisting of (1) one or more wheels;

(2) one or more tracks;

(3) a structure that enables the signal emitting platform to roll;
