Methods and systems for statistical based monitoring and power management

Abstract

Embodiments of the present invention provide devices and techniques for detecting anomalies in monitored environments. In one embodiment of the invention, data may be acquired by monitoring an environmental variable. Based on the acquired data, statistics may be calculated which model the behavior of the environmental variable. Based on the calculated statistics, a long-term behavior and a short-term behavior of the statistics may also be calculated. A difference between the long-term statistics and the short-term statistics may then be calculated. If the difference between the long-term statistical behavior and short-term statistical behavior exceeds a dynamic or predefined threshold, an action may be taken.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]Embodiments of the present invention provide techniques and devices for detecting anomalies in a monitored environment, and transmitting information in response to detecting the anomalies.[0003]2. Description of the Related Art[0004]Often it is desirable to monitor an environment to detect anomalies or changes in the environment. The environment may have many changing variables which indicate an overall behavior of the environment. These changes in the environment may necessitate some sort of action to prevent catastrophic consequences brought on by the changes. By monitoring the environment, one may be able to alert an individual to take action.[0005]For example, it may be desirable to monitor the flow of a river to detect changes in the flow of the river. Changes in the flow of a river may indicate an approaching flash flood. A device monitoring river flow may alert a meteorologist who may issue a flash flood warning ...

AI Technical Summary

Benefits of technology

Enables the detection of unknown anomalies while conserving power by transmitting data only when necessary, improving the mobility and effectiveness of monitoring devices.

Problems solved by technology

A disadvantage to these devices is that the abnormal behavior of the environmental variable being monitored must be known in advance in order to detect anomalous behavior.

Monitoring devices which continuously transmit data consume a great deal of power.

The problem with these solutions is that a connection to a wall power outlet, solar cells or a large battery pack may limit the mobility of the device.
