Leo M. Dekkers - Houston TX

Assignee:

Input/Output, Inc. - Stafford TX

International Classification:

G01V 116

US Classification:

181112, 181104, 181122, 181401, 181105, 367 35

Abstract:

A method and apparatus for isolating a seismic sensor module from high-g shock loads such as those encountered during handling, deployment and retrieval of the module. The sensor module includes one or more MEMS accelerometers in an electronics package. The electronics package is housed within a module case. And one or more isolators are disposed between the electronics package and the module case to provide shock isolation.

I/O Exploration Products (U.S.A.), Inc. - Stafford TX

International Classification:

H02G 1502

US Classification:

174 74R

Abstract:

The invention disclosed herein is for an improved electrical connector assembly used on couplers and program modules in marine streamers used in offshore seismic exploration. In particular, the invention disclosed herein is comprised of a deformable seal ring with a plurality of holes formed therein through which pass individual conductor wires through which are transmitted signals from various hydrophones disposed along the marine streamer. Deformable nipples are disposed on each side of the seal disk 16 around each of the openings extending through the seal disk. The seal disk and nipples are deformed around the conductor wires passing through the openings in the seal disk through use of a compression disk and spring which provides dynamic spring loading of the seal disk-conductor wire interface, thereby maintaining the integrity of the seal established between those components.
