  • Patent number: 6134183
    Abstract: An air-launched sonobuoy, particularly useful for under-ice surveillance, rries a descent-retardation parachute whose lanyards activate a surface float during descent. Upon impact into an ice region, a slip-rod is jarred loose from the cannister top thus freeing the surface float, and its RF antenna, to remain above the ice while the remainder of the components deploy.

  • Patent number: 6026056
    Abstract: A method and apparatus for controlling the operation of a multiple-element marine seismic pulse generating source in rough sea surface conditions. The method first determines the shape of the path along which the elements are traveling at the point in time just before each element of the source is activated. Once the shape of the path is known, the relative vertical position of each element relative to a fixed reference is determined. Adjustments can then be entered into the firing times for each element such that the primary pressure peaks constructively interfere with one another. In a preferred embodiment, a plurality of inclinometers associated with the harness from which the devices are suspended provides a tilt angle measurement from which the shape of the path can be determined and the firing times adjusted accordingly.

  • Patent number: 5963506
    Abstract: A low flow noise sonobuoy suspension system having a surface float, a sussion cable having a compliant portion, a bridle, a hydrophone, a mechanical cable, a terminal weight, and a drogue. The hydrophone is located within the bridle and is attached to the bridle so as to allow the hydrophone to remain roughly vertical if the bridle is tilted. The bridle is located below the surface float and is connected to the surface float by means of the suspension cable. The drogue is located below the bridle and is connected to the bridle by a mechanical cable. The drogue is connected at an attachment point on the mechanical cable such that the relative velocity of the hydrophone is negligible. The terminal weight is also attached to the mechanical cable. By means of this arrangement, both the horizontal motion noise caused by the relative velocity of the hydrophone, and the vertical motion noise caused by the surface waves are reduced.

  • Patent number: 5432750
    Abstract: A deployment system is disclosed for deploying a vertical, sub-surface bud, underwater acoustic sensor array in the ocean which includes a mechanical load transfer and cable separation mechanism which is embodied as a rigid triangular member. The vertical, sub-surface buoyed underwater acoustic sensor array is attached to a support cable which is connected at one end to the sub-surface buoy and at its other end to one of the vertices of the rigid triangular member. An anchor is attached to another vertex of the rigid triangular member and the third vertex of the triangular member is fitted with a strain relief/cable support, rotatable leg that is in turn attached to the deployment or shore cable. After deployment, the triangular member becomes the mechanical link between the array anchor and the array's vertical support member. It also acts as a mounting surface for the necessary electrical cable junction boxes or other required instrumentation and hardware.

  • Patent number: 5418757
    Abstract: A battery operated system 20 responds to coded acoustic signals 15 for releasing a buoyed housing from an underwater anchor 21 to carry a retrieval line attached to a retrievable underwater object to the water surface. A novel tethering mechanism 26 is provided for attaching the housing to a line 25 tethered to the anchor and for releasing it in response to the coded acoustic signals. The tethering mechanism operates in two diverse modes. Thus the housing is released from its tether line thermally by battery power which melts an expandable wax body in a thermal actuator 36 to move an actuating member 37 through a line release stroke. However, the tether line is attached by a manually actuated latching mechanism 45, 47 provided for retethering the housing at a different location without draining battery power for resetting the latching mechanism.

  • Patent number: 5398214
    Abstract: An underwater acoustic surveillance system for obtaining data related to nd sources of interest in a large geographic area over long periods. A number of acoustic sensors are dropped from an aircraft for placement on the bottom of the sea at known locations. Each sensor automatically deploys a parachute to retard the descent in the air. A parachute riser weak link releases the parachute upon immersion in the water, and a latch operable at a preselected depth allows cylindrical staves to spread apart and form a stable platform on the bottom from which a hydrophone suspends and an acoustic projector tethers. A web-like flow shield unfolds between adjacent staves of the platform to provide additional retardation during the descent in the water and to reduce hydrophone noise due to water currents at the bottom.
