Abstract

A sensor package may include a sensor housing unit and a first sensor that may acquire a first set of measurements within a first measurement range. The sensor package may also include a second sensor configured to acquire a second set of measurements within a second measurement range. The first measurement range and the second measurement range may include an overlapping range used to calibrate the first set of measurements, the second set of measurements, or both.

First claim

The invention claimed is:

1. A sensor package, comprising:
a sensor housing unit;
a first accelerometer sensor configured to acquire a first set of measurements associated with a ground roll of seismic energy detected within a first measurement range of the first accelerometer sensor, the first accelerometer sensor having a first accuracy property, a first resolution, and a first calibration stability associated with an amount of time; and
a second accelerometer sensor configured to acquire a second set of measurements associated with the ground roll within a second measurement range of the second accelerometer sensor, wherein the second measurement range includes a higher measurement value as compared to a greatest measurement value within the first measurement range, the second accelerometer sensor being a different type of accelerometer sensor as compared to the first accelerometer sensor and having:
a second accuracy property greater than the first accuracy property,
a second resolution lower than the first resolution; and
a second calibration stability greater than the first calibration stability, wherein the first measurement range and the second measurement range comprise an overlapping range used to automatically calibrate the first set of measurements at a periodic frequency, wherein the first set of measurements is automatically calibrated with respect to the second set of measurements based on a first portion of the first set of measurements and a second portion of the second set of measurements, wherein the first portion and the second portion are within the overlapping range; and

a processing system configured to obtain a third set of measurements having a third resolution higher than the second resolution by applying a gain to the second set of measurements based on automatically calibrating the first set of measurements, wherein the third set of measurements is within the first measurement range and corresponds to a saturation region of the first accelerometer sensor.

2. The sensor package of claim 1 , wherein the first accelerometer sensor comprises a piezoelectric accelerometer.

3. The sensor package of claim 1 , wherein the second accelerometer sensor comprises a Micro-Electro Mechanical Systems (MEMS) accelerometer.

4. The sensor package of claim 3 , wherein the MEMS accelerometer is configured to acquire a one-dimensional acceleration measurement.

5. The sensor package of claim 3 , wherein the MEMS accelerometer is configured to acquire a three-dimensional acceleration measurement.

6. The sensor package of claim 1 , wherein the processing system is configured to:
perform a synchronization-based cross-correlation operation on the first portion of the first set of measurements and the second portion of the second set of measurements;
determine a time shift based on the synchronization-based cross-correlation operation;
apply the time shift to the first set of measurements;
adjust an amplitude to the first set of measurements based on the second set of measurements;
normalize the first portion of the first set of measurements for the first measurement range; and
combine the normalized first portion of the first set of measurements with the second portion of the second set of measurements.

7. The sensor package of claim 1 , wherein the processing system is configured to:
receive a remote clock signal via a communication protocol;
determine an expected transmission delay for the remote clock signal based on the communication protocol; and
synchronize a clock based on the remote clock signal and the expected transmission delay.

8. The sensor package of claim 1 , wherein the processing system is configured to:
determine whether a base station is within a distance threshold; and
send the first set of measurements, the second set of measurements, the third set of measurements, or any combination thereof to an additional sensor package within the distance threshold in response to determining that the base station is outside the distance threshold.

9. The sensor package of claim 1 , wherein the first set of measurements and the second set of measurements comprise acceleration data.
