An acquatic retrieval apparatus is provided which includes a flotation bag, gas pressure bottle which is associated with the flotation bag for inflating the bag, a puncturing device connected to the pressure bottle for puncturing the bottle to let the pressurized gas into the bag, a timer connected to the puncturing device for activating the puncturing device so as to puncture the bottle after a predetermined time, and an on-off switch adapted to be connected to a power source for applying power to the timer when the switch is turned on.
A lost pet retrieval collar receives a coded radio signal and activates a puncturing device to release gas from a pressurized canister to inflate a balloon creating a visual alarm that the pet is lost. The pet collar also contains information necessary to enable a passerby to contact the pet owner. In one embodiment, the puncturing device utilizes a spring loaded pin; in a second embodiment, the puncturing device utilizes a solenoid valve; in a third embodiment, a laser is employed.
Hurlable, water rescue aid 10 comprising an initially collapsed, gas-inflatable buoyancy element 12, a ball-shaped bracket 24 supporting the buoyancy element in collapsed condition generally within the locus of the bracket, a compressed gas supply 32 within the bracket for inflating said element, a penetrating tip 40, adapted to release the gas supply from the cylinder in advance of hurling the aid toward a person to be rescued, and passageways 52 metering flow of released gas from the supply into the buoyancy element, whereby the buoyancy element is substantially collapsed at the commencement of flight but substantially inflated at the termination of flight for use by the person.
The present invention relates generally to a method and related devices for the deactivation of landmines. More particularly, the present invention includes several devices used to carry out a method of training live animals, such as rats, to seek out and destroy active landmines in the field, or to localize, unearth, and mark the location of active mines, thereby reducing the danger of their later removal by valuable sniffing mine clearing animals, technology, and mine clearing personnel, making a landmine clearance effort more effective and efficient.
The present invention relates to a gas management device 10; 20; 30; 40; 50 comprising: a gas inlet 11; 32; 42; 52 adapted to secure a casing of a vessel 22, preferably a closure 26 sealing an opening of a gas cylinder containing pressurized gas; a gas outlet 12; 33; 43; 53 adapted to be secured to an inflatable unit 23; and a puncture device 10b; 31b; 41b; 51b for puncturing the casing of the vessel 22. The puncture device 10b; 31b; 41b; 51b comprises a pyrotechnical detonator 16 that, when activated, creates a chock wave which punctures the casing of the vessel 22, whereby gas from the vessel 22 is directed to the inflatable unit 23. The invention also relates to a method and a system for transferring gas from a pressurized vessel to an inflatable unit via a gas management device.
A pre-selected fish grazing system to enhance harvesting of such pre-selected fish from a body of water. The fish grazing system includes at least one conductor unit attached to a body of a pre-selected fish for acting as a guide for other preselected fish present in such body of water. A control device is disposed in such conductor unit for controlling a path the pre-selected fish is to follow. A predetermined number of buoys are strategically located in such body of water for sending communication signals to such at least one conductor unit attached to the body of the pre-selected fish to direct such pre-selected fish having such conductor unit attached thereto a desired location.
