Abstract: A thermoelectric cooler for maintaining intravenous (IV) solution within a temperature range of 1° C. to 4° C. for inducing rapid, emergency, point-of-injury, mild-to-moderate hypothermia. The thermoelectric cooler includes a substantially rectangular insulated container with a door extending in a vertical plane on the forward facing container wall and pivoting on a horizontal hinge located on the bottom edge of the door. The container is cooled by a thermoelectric module mounted between two heat exchangers and electrically powered fan assemblies. An electronic control unit controls the thermoelectric cooling module to maintain the interior of the insulated container and the IV solution within the set temperature range. The thermoelectric cooler has an exterior display panel with warning lights to visually communicate to the user if the interior temperature is in or out of range.

Abstract: A streamer-cable assembly is provided having a tubular outer jacket enclosing an open-cell and closed-cell foam core. The foam core provides an axial hole for retaining a plurality of pressure sensors and a plurality of off-axial holes providing passages for the transmission bundle. Longitudinal channels along the exterior of the foam inserts receive substantially rigid stress members which provide longitudinally strength to the streamer. Cable noise associated with the cable jerk and cable whip/vibration is radially reduced by the open-cell foam core and rigid stress members while the closed-cell foam core provides buoyancy to the streamer cable at the connectors between sections.

Abstract: An apparatus is disclosed for balancing a seismic streamer cable. The housing is comprised of a first and a second valve coupled about the streamer cable. Each valve has a clasp adapted to engage a socket on the other valve to ridigly fasten the valves together about the streamer cable. The housing surrounds and retains weights applied to the streamer cable. An alternate embodiment is disclosed where the weight is integral with each valve. The exterior of the housing is designed to produce laminar flow conditions for the fluid passing over the housing as the cable is under tow, reducing ambient noise detected by the sensors within the streamer cable.

Abstract: A streamer-cable assembly is provided having a tubular outer jacket enclosing an open-cell foam case providing an axial hole for retaining a plurality of pressure sensors. A plurality of off-axial holes provide passages for the transmission bundle. Longitudinal channels along the exterior receive stress members which provide longitudinal rigidity to the streamer. Cable noise associated with cable jerk, and cable-whip or vibration is radically reduced by the foam core and rigid stress members.
