Abstract:
The Wearable Satellite Tracker (WST) is a worn by the operator and carries a two-way satellite transceiver that communicates to a Central Tracking Monitor a message with; a unique serial number of the device, position information (via GPS receiver), and the status of the WST. Optionally, the WST will have a satellite telephone interface to place a null911null or emergency call to the Central Tracking Monitor. The WST can be used anywhere in the world and requires no other local equipment. An embodiment of the WST is a Personal Flotation Device or Life Vest with the WST embedded in it. The Life Vest owner can trigger the Life Vest with a panic button at will or, upon being immersed in water, the WST will self-trigger. In the Alarm-state, the WST send frequent alarm messages to the Central Tracking Monitoring, a LED Status Indicator will show the operator of the WST its progress in sending a message to the Central Monitoring Center. These are acknowledged messages and the WST wearer knows they have been received. Both status checks and alarms messages will be sent to a Central Tracking Monitor. The Central Monitoring Center will then mate the unique ID of the WST and with its database information, and begin notifying the appropriate authorities in the event of an alarm message. Most importantly with the WST, there is no new equipment or personal needs to be added to the vessel or operation unit to monitor the WST. The WST is self-contained and includes a visual check for operator to confirm the operational status of the battery, GPS, satellite transceiver and communication to the Central Tracking Monitor. Test messages can be initiated by the wearer of the WST to ensure the complete system is working before the beginning a shift, or during, a work shift.
Abstract:
A sand spike system anchors a cable in an earthen substrate. A penetrator connected to the cable has folded petal-shaped sections of spring steel propelled into the earth by a propellant. Cables connected to opposite petal-shaped sections help arrest penetration and spread the folded petal-shaped sections outwardly to increase the resistance to tensile loads. Sand spike system may use a delay activated or an electrically initiated propellant to drive the penetrator into the earth instead of mechanical, hydraulic, or pneumatic force. This permits remote initiation of sand spikes from a safe distance on land or underwater. In addition, each sand spike creates far a greater surface area to entrain and use the earthen substrate and not friction to anchor, and, as a consequence, it safely bears greater tensile loads on the cable.
Abstract:
A low watch circle buoy system (LWCBS) uses global positioning system (GPS) P(Y) code coordinate sensing and transmission to mark its position in wr depths up to 40 feet to a positional accuracy of 3 meters or less. LWCBS maintains this position with a flotation unit on the water's surface that transmits signals representative of its location. A submerged unit is affixed to a surface at the bottom of the body of water and has outwardly reaching extensions that lie adjacent the surface. The extensions are tethered to the flotation unit by lines that are each connected between a distal part of each of the extensions and the flotation unit. A spool on each distal part each deploys and secures one of the lines to maintain the flotation unit substantially vertically above the submerged unit. These tether lines limit the range (watch circle) the flotation unit may traverse on the water.
Abstract:
A method and apparatus for automatically releasing a gas from a pressurized cartridge of the gas is provided, especially for the purpose of inflating an emergency balloon. The apparatus includes an automatic signal balloon inflator, having a support structure, an upper surface and a bottom plate. The bottom plate has at least a single cartridge mount, each with a vent and a pin port. The pin port connects to the cartridge mount. At least a single pressurized cartridge, containing a gas stored under pressure, is received into each cartridge mount in the support structure. A spring loaded piston is mounted upon the support structure. A plunger with a piston contact surface and a puncture pin is forced by the spring loaded piston to depress and penetrate the pressurized cartridge, releasing the gas contents of the pressurized cartridge through the vent. A firing spring forces the piston to engage the plunger. The emergency or signal balloon inflator also has a lightweight and reliable self-sealing one-way valve that, after the balloon is filled, can snap off from the support structure. The emergency balloon inflator also has tether, which feeds a line to the balloon with a minimum possibility of knots and tangles.
Abstract:
Distress signal kits comprise a parafoil for carrying aloft various emergency or distress signals such as radar reflective materials, lights, flares, distress flags or smoke signals. Preferably the parafoil itself is colored International orange and contains a U.S. Coast Guard-approved distress signal (BLACK SQUARE AND CIRCLE) on both top and bottom surfaces. The parafoil can be used to raise a spinnaker sail attached to a vessel or swimmer. The spinnaker can also carry radar reflective components and/or distress flags, and can be fitted for other survival uses.
Abstract:
An improved search and rescue transponder having an improved housing assembly that permits the device to be turned on or off by rotating one segment of the housing relative to the other for ease of use even with heavy or bulky gloves. In addition, the housing assembly exterior surface includes a plurality of longitudinal ridges for ease in gripping. The housing assembly includes an upper housing and lower housing joined by a retaining ring and O-ring seal, eliminating the need for fasteners for manufacturing efficiency. The lower housing includes quick disconnect that attaches to a mounting disk affixed to a ship or life raft. The mounting disk includes a plurality of resilient fingers which act in conjunction with cam surfaces on the flange of the lower housing, which when rotated together allow for a quick disconnect. The improved overall reduced size and configuration of the housing assembly contains five batteries arranged circularly in a side-by-side array, packed together in the lower housing, allowing for a SART of reduced length and easily handling configuration.
Abstract:
An improved water flotation release device for locating the submerged position of ships that have sunk. The device comprises an improved release buoy that is self contained and communicating and a releasing system that leads to non-violent and reliable release from the sinking ship.
Abstract:
1. An apparatus comprising an intelligence capsule, a radio buoy, releasable means for retaining said buoy and said capsule attached together to be able to sink in sea water as a unit, pressure-responsive means for initiating release of said releasable means at a predetermined hydrostatic pressure, means for urging apart said buoy and capsule when said releasable means has been released;said capsule including a free-flooded chamber; a frangible cap; said chamber being formed at least in part by said frangible cap; in said chamber, a subsurface float assembly comprising an inflatable float adapted to break and remove said cap upon inflation, a winch containing a line connected to said buoy, and a depth compensating dispenser for line connecting said capsule with said subsurface float assembly, said dispenser including means to restrain payment of line from said dispenser;hydrostatic pressure responsive means, disabled from operation by said frangible cap, for activating said payment-restraining means, whereby said payment-restraining means is activated only upon removal of said frangible cap;means responsive to a coded sonic signal for causing said winch to release said buoy to rise to the surface of water; andmeans for causing said winch to retract said buoy to a predetermined depth below the water surface.
Abstract:
An oceanographic long spar buoy including a plurality of elongated tubular members connected to each other in an end-toend relationship to define a body of the buoy. A weatherproof data handling instrumentation container is demountably secured to an upper unsubmerged end of the body. The instrumentation container houses equipment which is coupled to instrument transducers mounted at selected locations along the buoy. The container is removable as a unit from the buoy for ease of servicing or repair of the contents thereof.
