20110110193 | WIRELESS EXPLORATION SEISMIC SYSTEM - Systems and methods for seismic data acquisition employing a dynamic multiplexing technique. The dynamic multiplexing technique may include advancing one or more modules in a seismic array through a multiplexing signature sequence in successive transmission periods. The multiplexing signature sequence may be random or pseudo-random. A shared multiplexing signature sequence may be used at all the modules in the seismic array. As such, modules belonging to a common collision domain may operate out of phase with respect to the shared multiplexing signature sequence. | 05-12-2011 |
20120008460 | DATA ACQUISITION SYSTEM WITH REMOVABLE - Data acquisition modules and systems including batteries with integrated data storage. The battery with integrated data storage can be selectively removed from the data acquisition module. This allows for reduced logistical effort associated with data retrieval and battery charging. For instance, the entire data acquisition module need not be transported to a central location for data recovery and charging, but rather the removable battery with integrated storage may be removed and transported. Also facilitated is extended surveys in that the battery or storage module may be replaced, such that survey design limitations such as storage capacity or battery life may be eliminated. | 01-12-2012 |
20120170407 | SYSTEMS AND METHODS FOR IMPROVING BANDWIDTH OF WIRELESS NETWORKS - Systems and methods for seismic data acquisition with location aware network nodes. Based on location information of the nodes of the network, a multiplexing signature may be provided for the node. The location information may be used in conjunction with other information (e.g., location information of other nodes in the network and transmission ranges for nodes in the network) to determine collision domains. A multiplexing signature may be assigned to a node based on information regarding a collision domain to which the node belongs. As such, the assigned multiplexing signature may be used to avoid data collisions. | 07-05-2012 |
20120170408 | SYSTEMS AND METHODS FOR SEISMIC DATA ACQUISITION - Systems and methods for seismic data acquisition utilizing wireless modules to perform real time data read out. The wireless modules may be assigned a shared multiplexing sequence through which each module advances in successive transmission periods. Wireless modules belonging to a shared collision domain may be operated out of phase from one another with respect to the shared multiplexing signature sequence. As such, a dynamic multiplexing regime may be implemented. The shared multiplexing signature sequence may include, among others, a plurality of different frequencies, a plurality of different codes, or a plurality of different discrete time periods. | 07-05-2012 |

20140307526 | MULTIMODE SEISMIC SURVEY SYSTEM - A multimode seismic survey system is disclosed where seismic information for a given seismic survey is read out by different seismic units using different modes. Such multimode systems encompass hybrid arrays where information is read out via different output modes for a single seismic event, and other multimode arrays where seismic information is read out via different modes for different seismic events. The modes utilized in such arrays may include wireless, nodal and/or cable modes. The multimode arrays can be implemented using multimode seismic units or single mode seismic units. In any event, the multimode arrays can be utilized to achieve a combination of advantages associated with the different readout modes or to address any of various multimode mode contexts in relation to seismic surveys. | 10-16-2014 |
