An apparatus and method generate oxygen gas from sodium percarbonate and water including seawater. The apparatus includes a chamber, a valve system, and an output port. The valve system controls combining a quantity of the sodium percarbonate, a quantity of the water, a quantity of potassium iodide, and optionally a quantity of sodium sulfate decahydrate. A chemical reaction between the sodium percarbonate and the water in the chamber generates oxygen gas, which is output at an output port from the chamber. The potassium iodide is a catalyst for the chemical reaction and optionally the sodium sulfate decahydrate is a temperature moderator for the chemical reaction. A ratio between the water and the sodium percarbonate is in a range of 2.5 to 8 by weight. A ratio of the potassium iodide per liter of the water yields a molarity in a range of 0.25 to 1.25.

A sandwich cable fairing designed for attachment to cables that are towed at operational speeds by marine vessels. The sandwich cable fairing has a design that combines layers of elastic and damping materials. The fairing dampens the vibration caused when the cable is towed at operational speeds. The outer layers (“bread”) of the fairing are made from a material with a modulus of elasticity that provides a desired amount of stiffness. In the middle of the sandwich cable fairing is damping layer made from a viscoelastic material. The layering of materials allows the fairing to have the flexibility to be crushed by cable equipment while maintaining the requisite stiffness to reducing flapping and the resulting vibration.

A propeller pitch adjustment assembly is provided with a base hub operatively connected by blade shafts to propeller blades in which each blade rotates about an axis of each shaft. Each blade shaft is radially disposed about a propeller drive shaft and parallel to a pressure flange of a base hub spring plate. The spring plate counterforces the blade rotation with a lever screw that impacts the plate. An opposing spring transfers a load to the plate. The equilibrium position of the plate is determined by the spring force on the lever and a counteracting force exerted on the lever by a lift force generated by fluid flow over a propeller blade. A capping mechanism can provide a preload to the spring. A force exerted by the lift of the blade on the lever screw results in a blade pitch change.

Exemplary inventive practice improves the taxiing dynamics of a seaplane by propulsively imparting roll moments so as to continually encourage levelness of the two wings, thereby maintaining both wings completely above (out of) the water. Two matching motor-driven propellers are correspondingly positioned at or near the wingtips. A computer receives sensory motion inputs and transmits sequential commands that continually adjust the respective propulsive forces of the wingtip propellers by effecting equal and opposite changes in their respective rotational speeds. An increase in one wingtip propeller's rotational speed is concomitant a decrease in the other wingtip propeller's rotational speed, wherein the increase and the decrease are of the same magnitude. The seaplane rolls upward on the wing whose wingtip propeller is increasing in rotational speed. Control of the seaplane's rolling motion is thus enabled by a sustained propulsive equilibrium between the two wingtip propellers.

Abrégé

A sensor platform is provided with a rigid hull having a planar shape having a bow, stern, a port and a starboard side. The platform includes an inflatable perimeter tube having sides extending along a perimeter of the hull. A tow connection is at the bow and rigid control surfaces are at the stern. A planar sensor array is disposed within the platform. The planar sensor array includes inflatable sensor panels attached to the port and a starboard side of the perimeter tube. Each of the inflatable sensor panels has a plurality of sensors embedded with electrical conductors for power and data transfer. A manifold disposed within the platform operationally connects to the inflatable perimeter tube and the inflatable sensor panels. An electrical controller disposed within the platform connects to the sensors and the manifold.

A dewar includes two coaxial openings of different sizes (e.g., to allow for interfacing with a Stirling cryocooler and a Stirling generator), a polytetrafluoroethylene or glass inner chamber (e.g., to reduce conductive heat transfer, particularly through the dewar neck), and an integrated, annular desiccant ring (e.g., for drying low-pressure, ambient air).

A system and related methods that generate encryption keys using two inputs. The first input is random data measured or supplied at the time the encryption keys are created. The second input is predetermined data held by the server and device. Given knowledge of the predetermined data and the random data, the UxS will be able to regenerate its previous encryption keys and also to re-establish communication by the server and device.

Abrégé

Provided is a broadband multi-line laser beam combiner apparatus and method that allows a broader spectrum of light to be emitted from a single optical path. The disclosed apparatus and method provide the ability to combine a number of unique laser lines including both visual and infrared light as one optical beam that is emitted from a single emission aperture or window using both conventional dichroic mirrors and an imaging dichroic mirror. The apparatus and method are based, in part, on an optical material selection and design that affords the ability to combine multiple broadband laser sources. Rather than merely emitting discrete laser lines, the presently disclosed broadband multi-line laser beam combiner can emit an “ultra-wide-continuum” of wavelengths from approximately 400 nm to 5000 nm at emitted optical powers greater than five (5) Watts from one emission aperture/window.

Abrégé

The present invention relates to methods and processes to prepare pre-mixed compositions that can be combined to form pyrotechnic compositions in mixed multiple parts. In exemplary embodiments, a binder curing agent ingredient is premixed with pyrotechnic fuels and can also include other pyrotechnic additives and processing aides. Other binder ingredients such as a binder resin can be premixed with the pyrotechnic oxidizers and can also include other pyrotechnic additives and processing aides. The resulting mixtures are not explosive and are much safer to handle and easier to store for extended shelf-life over a final pyrotechnic composition. Further, the pre-mixed mixtures can be stored in bulk until needed and rapidly combined to achieve the final pyrotechnic composition.
