| 20090168602 | Seismic data recording - A seismic survey is conducted by positioning an array of remote acquisition units (RAUs) ( | 07-02-2009 |
| 20090086797 | Data transmission system - A data transmission system, particularly for use in seismic data acquisition, transmits digital signals from remote units to a central control unit via a backbone network and root nodes. Data is transmitted wirelessly between the remote units and the root nodes by means of each remote unit having two transceivers, one of which acts as a client and one as an access point. The remote units transmit metrics which enable the adaptive formation of a mesh-like network. | 04-02-2009 |
| 20080291783 | Seismic data acquisition - A seismic system uses a plurality of remote acquisition units in each of which geophone signals in digital form are temporarily stored in a buffer for near-real-time transmission by a transmitter. The whole of the digital data is also stored in a bulk store within the acquisition unit, from which it can be retrieved and transmitted under control of signals received by a receiver. This allows a central control unit to cause lost or low quality data to be retransmitted in a flexible manner. | 11-27-2008 |
