In a seismic exploration system, an adaptive seismometer group recorder having enhanced operating capabilities for acquiring, processing, and storing seismic signals is provided. The adaptive seismometer group recorder includes a solid state memory, a microprocessor and input means for electronically downloading operating programs into the solid state memory whereby menus of recorder operating parameter are provided by the operating programs to the microprocessor to electronically reconfigure the SGR for various geological settings. The microprocessor is responsive to coded signals for selecting sets of recorder operating parameters from the menu of recorder operating parameters provided by the operating programs. The electronically downloaded menus of recorder operating parameters digitally reconfigure the operating characteristics of the seismometer group recorder without necessitating the implementation of hard wired circuitry changes.

Adaptive seismometer group recorder having enhanced operating

A portable thermally insulated case has an outer shell formed of a bottom wall and upwardly extending side walls integral with each other with integral rigid polyurethane foam adhering to the inner surface of each of the walls. A cover, which has rigid polyurethane foam on its inner surface, is hinged to the rear upwardly extending wall to close an access opening at the top of the outer shell. Each of the bottom and upwardly extending walls of the outer shell has a separate container in contact with the inner surface of the polyurethane foam and defining a recess therebetween. The cover has a container supported within the rigid polyurethane foam and substantially closing an access opening at the upper ends of the separate containers adjacent the upwardly extending walls so that the containers substantially surround any object within the recess. Each of the containers has a phase change material therein to supply heat to any object within the recess. Each of the containers of the outer shell has an electrical heating element in contact with its inner surface and connected by wires exteriorly of the case to enable heat to be supplied from an external power source to the phase change material to change it to its original state when the case is disposed at a location having an external power source.
