Sensor assembly having a seismic sensor, pressure sensor, and processor to apply first and second digital filters
First Claim
1. A sensor assembly comprising:
- a housing structure;
a seismic sensor in the housing structure to measure seismic waves propagated through a subterranean structure;
a pressure sensor in the housing structure;
a processor in the housing structure configured to;
receive a first signal based on an output of the seismic sensor, and a second signal based on an output of the pressure sensor;
apply a first digital filter to the first signal;
apply a second digital filter to the second signal,wherein application of the first digital filter and second digital filter is to cause production of a substantially zero output by the processor in response to input that includes just noise data detected at the seismic sensor and the pressure sensor; and
a storage medium to store a collection of digital filters, wherein the processor is configured to select the first digital filter from among multiple digital filters in the collection, and to select the second digital filter from among multiple digital filters in the collection, and wherein selecting the first and second digital filters is according to one or more criteria.

Abstract
A sensor assembly includes a housing structure, a seismic sensor in the housing structure to measure seismic waves propagated through a subterranean structure, and a pressure sensor in the housing structure. A processor in the housing structure is configured to receive a first signal based on an output of the seismic sensor, and a second signal based on an output of the pressure sensor. First and second digital filters are applied to the first and second signals. Application of the first and second digital filters to the first and second signals causes production of a substantially zero output in response to input that includes just noise data detected at the seismic sensor and the pressure sensor.
