| 20140098641 | METHOD AND SYSTEM FOR TRANSMISSION OF SEISMIC DATA - The transmission method utilizes multiple seismic acquisition units within an array as intermediate short range radio receivers/transmitters to pass collected seismic data in relay fashion back to a control station.

Preferably, as a transmission is passed along a chain, it is bounced between seismic units so as to be relayed by each unit in the array. | 04-10-2014 |
