Abstract: A coupler including an at least partially cylindrically shaped external body portion having a longitudinal axis, which further includes an integral first and second, axially opposed ends that have a taper along the longitudinal axis. The coupler includes an integral gate consisting of two axially opposed, disconnected tongue sections having an open space there between. The at least partially cylindrically shaped external body portion has an open space at least partially enclosed by an inner surface of the body portion and disposed over at least a portion of the at least partially cylindrically shaped external body portion. The external body portion is characterized by a maximum radial dimension, including a circumferential region of the at least partially cylindrically shaped external body portion intermediate the first and second axially opposed ends where the gate is disposed.

Abstract: A coupler for a cable includes a body portion having integral first and second ends and an integral gate having a key entry region, wherein the body portion has a free space at least partially enclosed by an inner surface of the body portion and the gate. A complimentary coupling ring includes an integral perimetal body having a head section, a foot section, and two arm sections therebetween, wherein at least one of the arm sections has a key region, wherein the key region consists of a solid, integral portion of the at least one arm section. A coupler/coupling ring assembly comprises a coupler and a coupling ring that is removeably engageable with the coupler. The coupler/coupling ring assembly is suited for interconnecting lengths of cable, particularly suited for, but not limited to, undersea applications such as attaching a seismic data recording device to the coupler via the coupling ring.

Abstract: A coupler for a load-bearing, non-signal-transmitting cable includes a body portion having integral first and second ends and an integral gate having a key entry region, wherein the body portion has a free space at least partially enclosed by an inner surface of the body portion and the gate. A complimentary coupling ring includes an integral perimetal body having a head section, a foot section, and two arm sections therebetween, wherein at least one of the arm sections has a key region, further wherein the key region consists of a solid, integral portion of the at least one arm section. A coupler/coupling ring assembly includes a coupler and a coupling ring that is removeably engageable with the coupler. The coupler/coupling ring assembly is particularly suited for interconnecting lengths of load-bearing, non-signal-transmitting cable, particularly suited for, but not limited to, undersea applications such as attaching a seismic data recording device to the coupler via the coupling ring.

Abstract: A marine seismic exploration method and system comprised of continuous recording, self-contained ocean bottom pods characterized by low profile casings. An external bumper is provided to promote ocean bottom coupling and prevent fishing net entrapment. Pods are tethered together with flexible, non-rigid, non-conducting cable used to control pod deployment. Pods are deployed and retrieved from a boat deck configured to have a storage system and a handling system to attach pods to cable on-the-fly. The storage system is a juke box configuration of slots wherein individual pods are randomly stored in the slots to permit data extraction, charging, testing and synchronizing without opening the pods. A pod may include an inertial navigation system to determine ocean floor location and a rubidium clock for timing. The system includes mathematical gimballing. The cable may include shear couplings designed to automatically shear apart if a certain level of cable tension is reached.
