Abstract

An electronic device is configured to analyze movement data generated by a sensor (e.g., an accelerometer assembly) in the electronic device to determine if the electronic device should be activated from a reduced power state. A control circuit in the electronic device can compare the movement data to a predetermined movement pattern to determine whether the movement should be ignored, or if the movement is consistent with a user shaking the electronic device to activate the electronic device. As a result of this approach, erroneous activation of the electronic device is avoided, thereby preventing the electronic device from needlessly depleting its battery before deployment by the end user.

First claim

What is claimed is:

1 . A method of activating an electronic device comprising:
obtaining movement data indicative of movement of the electronic device; determining whether at least a portion of the movement data satisfies a predetermined activation criteria comprising one or more predetermined motion patterns of the electronic device; activating a power state based on determining whether the portion of the movement data satisfies the predetermined activation criteria; and disabling activation of the control circuit for a period of time in response to one or more consecutive determinations that the portion of the movement data does not satisfy the predetermined activation criteria.

2 . The method of claim 1 , wherein activating the power state comprises reverting to a first power state in response to determining that the portion of the movement data does not satisfy the predetermined activation criteria, wherein reverting to the first power state includes deactivating a control circuit.

3 . The method of claim 1 , wherein activating the power state comprises activating a third power state in response to determining that the portion of the movement data satisfies the predetermined activation criteria, wherein activating the third power state includes activating a communication interface.

4 . The method of claim 3 , further comprising:
transmitting the movement data to a host computing system during the third power state.

5 . The method of claim 1 , further comprising:
activating a second power state prior to obtaining the movement data, wherein activating the second power state includes activating a control circuit.

6 . The method of claim 1 , wherein obtaining the movement data includes receiving the movement data from a buffer that is part of a sensor that generates the movement data.

7 . The method of claim 1 , wherein the activation criteria includes at least one of a magnitude of acceleration, a change in acceleration, a number of changes in acceleration, or a predetermined pattern of acceleration changes.

8 . The method of claim 1 , wherein the predetermined motion pattern is representative of a user shaking the electronic device.

9 . The method of claim 1 , wherein the activation criteria includes a predetermined pattern of alternating acceleration.

10 . The method of claim 1 , wherein determining whether the movement data satisfies the predetermined activation criteria includes applying a statistical model to compare the movement data to the predetermined activation criteria.

11 . The method of claim 1 , wherein the predetermined activation criteria is based off of a trained model.

12 . The method of claim 1 , wherein the movement data is representative of movement of the electronic device over a fixed period of time.

13 . The method of claim 1 , wherein the movement data is acceleration data.

14 . An electronic device comprising:
a communications interface; a sensor configured to:
generate movement data indicative of movement of the electronic device; and
a control circuit configured to:
obtain the movement data from the sensor;
determine whether at least a portion of the movement data satisfies a predetermined activation criteria comprising a predetermined motion pattern of the electronic device;
activate a power state based on determining whether the portion of the movement data satisfies the predetermined activation criteria; and
disable activation of the control circuit for a period of time in response to one or more consecutive determinations that the portion of the movement data does not satisfy the predetermined activation criteria.

15 . The electronic device of claim 14 , wherein the control circuit is configured to activate a first power state in response to determining that the portion of the movement data does not satisfy the predetermined activation criteria, wherein activating the first power state includes deactivating the control circuit.

16 . The electronic device of claim 14 , wherein the control circuit is configured to activate a third power state in response to determining that the portion of the movement data satisfies the predetermined activation criteria, and activating the third power state includes activating the communications interface.

17 . The electronic device of claim 16 , wherein the control circuit is further configured to transmit the movement data, using the communication interface, to a host computing system during the third power state.

18 . The electronic device of claim 14 , wherein the activation criteria is at least one of a magnitude of acceleration, a change in acceleration, a number of changes in acceleration, or a predetermined pattern of acceleration changes.

19 . The electronic device of claim 14 , wherein the predetermined motion pattern is representative of a user shaking the electronic device.

20 . A non-transitory computer-readable storage medium having stored thereon computer-executable instructions that, when executed, configure a control circuit to:
obtain movement data indicative of movement of an electronic device; determine whether the movement data satisfies a predetermined activation criteria comprising a predetermined motion pattern of the electronic device; deactivate the control circuit in response to determining that the movement data does not correspond to the predetermined activation criteria; and activate a communication interface in response to determining that the movement data corresponds to the predetermined activation criteria.
