Pattern recognition based motion detection for asset tracking system
First Claim
Patent Images
1. A method of tracking an asset, the method comprising:
- detecting one or more motions of a transmitter located with the asset, wherein the one or more motions are detected using a motion sensor coupled to the transmitter;
identifying the one or more motions, wherein a motion is associated with a magnitude and a duration;
parameterizing magnitudes and durations associated with the one or more motions;
determining a deliberate motion threshold;
identifying one or more deliberate motions from the one or more motions, wherein a deliberate motion is a motion having a magnitude and a duration above the deliberate motion threshold;
combining the one or more deliberate motions to generate one or more consecutive actions, wherein the one or more consecutive actions have a corresponding signature;
analyzing the signature corresponding to the one or more consecutive actions, wherein analyzing includes correlating the one or more consecutive actions to an event; and
transmitting a data ping, wherein transmitting the data ping signifies qualification of the event.

Abstract
An asset tracking system that optimizes the value per ping by tying the ping to a pattern of movements of the asset. The asset tracking device will send a ping to a remote host (i.e., receiver) when predetermined qualified event is detected by the device. In such a manner, the value per ping is optimized, leading to increased battery life and decreased operational cost. To satisfy these conditions, the asset tracking device is equipped with appropriate sensors, actuators, and trigger mechanism(s). A four-phase methodology or algorithm used to detect and determine when detected motions and movements warrant triggering the data ping.

11. A wireless radio frequency (RF) tracking system comprising:
a transmitter located with an asset, wherein the transmitter includes; a motion sensor; an RF communication module; a processor; and a non-transitory computer-readable medium containing instructions that, when executed by the processor, cause the processor to perform operations including; detect one or more motions of the transmitter using the motion sensor; identify the one or more motions, wherein a motion is associated with a magnitude and a duration; parameterize magnitudes and durations associated with the one or more motions; determine a deliberate motion threshold; identify one or more deliberate motions from the one or more motions, wherein a deliberate motion is a motion having a magnitude and a duration above the deliberate motion threshold; combine the one or more deliberate motions to generate one or more consecutive actions, wherein the one or more consecutive actions have a corresponding signature; analyze the signature corresponding to the one or more consecutive actions, wherein analyzing includes correlating the one or more consecutive actions to an event; and transmit a data ping, wherein transmitting the data ping signifies qualification of the event. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
