Abstract: A device may include a secure processor and a secure memory coupled to the secure processor. The secure memory may be inaccessible to other device systems. The secure processor may store some keys and/or entropy values in the secure memory and other keys and/or entropy values outside the secure memory. The keys and/or entropy values stored outside the secure memory may be encrypted using information stored inside the secure memory.

Abstract: The present invention comprises a bellmouth adapter assembly for deploying nd retrieving a towed array from a vessel that includes a bellmouth having a rearwardly extending tubular member with an axial centerline, and a distal first flange member extending outwardly from the tubular member, the first flange member having a first inner curved surface. The adapter has a second flange member which is concentrically superimposed over and fixed to the first flange member and has a second inner curved surface. This second curved surface is selected so that its bend radius is larger than the bend radius of the first inner curved surface.

Abstract: A large diameter load monitor sheave is provided for measuring the tension n a cable. The sheave is rotatably mounted on a cantilevered, generally vertical, fixed axle. The cantilevered axle allows the cable to be looped over the sheave without having to thread the cable between axle supports. The lower end of the axle is attached to a plate which is bolted to a mating plate on a vertical rod. Slotted holes on the axle plate allow the tilt of the sheave to be adjusted. The length of the rod can be adjusted, thus adjusting the height of the sheave. The lower end of the rod is supported by a pin connection to a base plate. A collar surrounds the upper portion of the rod just below the plate connection and the collar is affixed to an upright member projecting from a mounting support. A tensile force on the cable is translated to a tensile force between the collar and the upright member which is measured by a load cell.

Abstract: The arrangement is directed to a roller excitation device for frictionally ngaging and turning rollers of a roller box assembly. The roller box assembly is of the type that includes a generally U-shaped housing having a partial tube which covers the open end of the housing, and a plurality of rollers captured by the housing. The rollers and partial tube define a space through which a cable is received. The arrangement being such that the rollers are adapted to roll upon engaging the cable located in the space defined by the tube and rollers. The roller excitation device includes a body portion fabricated from resilient material and sized for occupying the space defined by the tube and roller and for frictionally engaging the rollers, and means for moving the body portion over the rollers. Preferably, the body portion has an outer surface with a plurality of ribs extending outwardly along the circumference of the body portion.

Abstract: A small, strong swivel coupling includes a spindle connectable to a pulling device, the spindle having a reduced diameter, axially extending central core which is threaded to receive a thrust nut and a lock nut. At the other end of the coupling, an end cap is connected to an axially extending sleeve which has an inwardly protruding flange. The flange and thrust nut form oppositely facing surfaces which are separated from each other by a low-friction washer preferably made of polytetrafluoroethylene. The coupling can withstand large axial forces and still rotate to relieve torques which might damage a cable being pulled.
