Vanishing Sensor Measurement via Reference Data in M2M Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In machine-to-machine (M2M) systems, there is a challenge in managing and generating measurements for vanishing sensors, which disappear after fulfilling their role, such as disposable sensors in high-heat environments.
Innovation Solution
The solution involves using a reference sensor to generate a measurement for a vanishing sensor after it has vanished, by applying a preconfigured mathematical equation to the measurements from the reference sensor.

1Object-affected harmful factors
If a vanishing sensor is used in high-heat environments, then the sensor can fulfill its measurement role in harsh conditions, but the sensor disappears after use causing data interruption
Solution Approach 1:
The patent creates a virtual copy of the vanishing sensor's measurement data by using a mathematical equation that relates the vanishing sensor to a reference sensor. When the vanishing sensor disappears, the system generates its measurement values indirectly through the reference sensor's data transformed by the predefined equation, thus maintaining data continuity without requiring the physical sensor to persist.
2Reliability
If a reference sensor is used to generate measurements after vanishing sensor disappearance, then data continuity is maintained, but system complexity increases
Solution Approach 1:
The patent establishes a preconfigured mathematical equation that defines the relationship between the vanishing sensor and the reference sensor before the vanishing sensor is deployed. This preliminary setup allows the system to automatically generate vanishing sensor measurements from reference sensor data using the pre-defined relationship, reducing the complexity of real-time sensor management and elimination logic.

AI summary
In a machine-to-machine (M2M) system, a method for generating a measurement of a vanishing sensor may include steps of: receiving at least one of a first measurement of the vanishing sensor or a second measurement of a reference sensor, determining whether or not the vanishing sensor has vanished, generating a third measurement based on the second measurement in case the vanishing sensor is determined to have vanished, and storing the third measurement as a measurement of the vanishing sensor that has vanished. An apparatus for generating the measurement of the vanishing sensor in the M2M system includes a transceiver and a processor, where the processor is configured to perform the above steps.
