Land based unit for seismic data acquisition
First Claim
1. A land-based seismic data collection system, comprising:
- a case comprising a cap and a container, each of the cap and the container having a wall with an outer surface and an inner surface and a closed end, each of the walls forming an open end, the open ends in contact with each other;
a geophone disposed in the case; and
an external electrical contact disposed in a through bore of the cap, a first end surface of the external electrical contact exposed from a conductive pad element of a portion of the outer surface of the cap, and a second end surface of the external electrical contact communicatively coupled to an internal circuit board via a flexible electrical wire that provides non-rigid attachment of the external electrical contact to the internal circuit board.

Abstract
A self-contained, wireless seismic data acquisition unit having a cylindrically shaped case with smooth side walls along the length of the case. A retaining ring around the circumference is used to secure the cylindrical upper portion of the case to the cylindrical lower portion of the case. Interleaved fingers on the upper portion of the case and the lower portion of the case prevent the upper portion and the lower portion from rotating relative to one another. Ruggedized external electrical contacts are physically decoupled from rigid attachment to the internal electrical components of the unit utilizing electrical pins that “float” relative to the external case and the internal circuit board on which the pins are carried. The seismic sensors in the unit, such as geophones, and the antennae for the unit are located along the major axis of the cylindrically shaped case to improve fidelity and timing functions.
