Abstract: A noise canceling audio in/out device includes an audible in/out transducer operable to convert an audible noise signal to a noise signal and convert an audio transmit (TX) signal to an audible output signal. A transducer signal of the audible in/out transducer generated by the audio TX signal is affected by the noise signal. The noise canceling audio in/out device further includes a noise canceling circuit operable to convert a digital TX signal to a TX reference signal, compare the transducer signal with the TX reference signal to produce an analog comparison signal, where the analog comparison signal includes a representation of the audio TX signal and the noise signal, and regulate the transducer signal to substantially match the TX reference signal to remove the effect of the noise signal on the transducer signal.

Abstract: A stator vane includes a platform that defines an opening. The stator vane further includes an airfoil that has a leading edge, a trailing edge, a suction side wall, and a pressure side wall. The airfoil extends radially between a base and a tip. At least one of the base or the tip includes a protrusion. The protrusion extends into the opening of the platform such that the platform surrounds the protrusion of the airfoil. The stator vane further includes a braze joint disposed between and fixedly coupling the platform and the protrusion of the airfoil. The stator vane further includes a cooling circuit defined in at least one of the protrusion or the platform to cool the braze joint.

Abstract: Techniques are described herein for using a high-pressure reactor to separate clean water from dirty water without filtration and to extract and concentrate contaminants from dirty water for use as a fuel. In particular, techniques and systems are described for separating water from hydrocarbon contaminates, other BTU-laden compounds, and dissolved minerals, while also boiling water and condensing the resulting steam into distilled water. In addition, system in which the described techniques are performed can be used as a high-pressure pump for moving the separated hydrocarbon contaminates forward into other processes, such as a high-pressure reactor or incinerator.

Abstract: Fuel mixed in water is combusted in a reactor having an internal operating pressure and temperature greater than 3200 psi and greater than 374° C., where the combustion of the fuel is exothermic. Air and fuel are pressurized for introduction into the reactor to a pressure greater than the internal operating pressure using energy generated from the combustion of the fuel, and the pressurized air and the pressurized fuel are injected into the reactor. Pressurized water from the reactor is injected into a drive water column that is partially filled with water to increase a pressure of the drive water column, and water at a temperature less than 100° C. is injected into the reactor to replace water from the reactor that is injected into the drive water column. Pressurized water from the drive water column is used to drive a hydroelectric drive system to produce electrical power.

Abstract: In a general aspect, a system can include a reactor for combusting fuel and producing high-temperature, high-pressure liquid as a byproduct, and at least one vessel defining a cavity to be partially filled with water, with an air pocket within the cavity above the water. The system can further include respective valves to control admission of liquid from the reactor into the air pocket when the air pocket has a pressure lower than an operating pressure of the reactor, and to control emission of the water from the at least one vessel through of the vessel after the water in the at least one vessel has been pressurized by the liquid from the reactor. The system can also include a hydroelectric drive system for receiving water emitted from the cavity, and for converting energy in the received water into electrical energy.

Abstract: A charging system for charging a reactor with air used energy produced by the reactor and includes a vessel having a hollow interior cavity partially filled with a liquid slug, a first air pocket within the cavity on a first side of the liquid slug, and a second air pocket within the cavity on a second side of the liquid slug. The liquid slug forms a water trap seal in the cavity between the two pockets and moves within the vessel in a cycle in which gas is loaded into the first air pocket in a first stroke and gas in the first air pocket is compressed in a second stroke. Movement of the liquid slug during the second stroke is caused by an increasing pressure in the second air pocket due to introduction of high-pressure gas from the reactor into the second air pocket.

Abstract: A system and method are provided for a magazine-fed, pump-action firearm. The system comprises an extruded receiver having a longitudinal bore extending along the length of the extruded receiver, where the longitudinal bore forms a first opening in the extruded receiver for receiving a barrel, and a second opening in the extruded receiver for receiving a stock, a barrel extension key extending inward from an interior surface of the longitudinal bore, the barrel extension key configured to index and position the barrel, and a barrel nut configured to couple with the first opening of the extruded receiver and maintain the barrel substantially inside of the longitudinal bore between the barrel extension key and the barrel nut. The method includes extruding a receiver having a longitudinal bore, machining features on an exterior surface of the receiver, machining transverse openings in the receiver, and providing a barrel nut.

Abstract: The present invention provides a surgical specimen retrieval device that allows one-handed use by incorporating a geared spool to amplify take up of a flexible line to close the mouth of the specimen bag after the surgical specimen is deposited in the bag. The retrieval device includes a spool with an attached gear that is rotated by movement of a deployment rod with serrated teeth. A flexible line has a proximal end attached to the spool and the distal end attached to the mouth of the bag. When the deployment reel is moved from an extended position to an inserted position, the spool rotates and pays out flexible line to allow the mouth of the deployed bag to open. Once a specimen is taken and deposited in the bag, the deployment rod is moved from the inserted position toward the extended position. This rod movement rotates the spool to take up the line and close the mouth of the bag.
