20040252585, Dec 16, 2004
Filed:

Apr 14, 2004
Appl. No.:

10/492628
Inventors:

Dexter Smith - Columbia MD, US
Nicholas Evancich - Columbia MD, US
Michael McLoughlin - Sykesville MD, US
Douglas Wenstrand - Columbia MD, US
International Classification:

G01V001/18
US Classification:

367/066000
Abstract:

A high capacity digital geophone system capable of distributing seismic data over a computer network connection in a real-time manner. Each geophone can convert seismic energy signals to analog then digital data before forwarding the observed data to a network connection for dissemination. Moreover, each geophone may be embedded with a processing capability that allows for instant front end processing of data. Remote processing computers can then access geophone data over the network connection and feed it into software analysis applications.
