20120227303 | Magnetohydrodynamic Sensor System - A magnetohydrodynamic sensor system for testing or arming high speed projectiles by providing a high speed signal at the time of projectile exit from a firearm. The sensor unit generally includes a magnet, a first electrode, and a second electrode spaced apart from the first electrode. The first electrode and the second electrode detect an induced voltage caused by a conductive gas passing through a properly oriented magnetic field as the gas exits the barrel with a projectile. The sensor unit may be mounted on the barrel of a firearm, etc., may be mounted on the projectile, and/or motor of the projectile (e.g. rocket). When mounted on a projectile, the sensor unit or onboard electrical circuitry are preferably located at the rear end of the projectile to allow activation of the onboard electrical circuitry and/or sensor unit when substantially the entire projectile exits the barrel for added safety. | 09-13-2012 |

20120245498 | Immobilizer - This invention generally relates to a product and method to restrain movement, and more particularly to a product and method to releasably restrain the movement of a part of the human body, such as an arm or a leg. In one embodiment of the invention, a first piece is releasably positioned at a part of the body the movement of which is desired to be restrained and a second piece is positioned at the desired location of restraint. The first piece and the second piece are adapted to be releasably connected to each other, such as by magnetic forces, the attractive magnetic forces of two or more magnets, or by mechanical forces such as by a snap, button, buckle, pin, hook and loop fastener or other device. | 09-27-2012 |

20100082116 | ANATOMICALLY-CONFIGURED ADJUSTABLE UPPER EXTREMITY PROSTHETIC DEVICE - An upper extremity prosthetic device is provided that comprises three main components, namely, an arm cuff, a forearm section and a distal connector. The arm cuff is adjustable to accommodate lower arms of different sizes. The forearm section may be constructed in certain limited sizes to accommodate different sized forearm residual limbs. The distal connector is designed to connect to any of the forearm section configurations, and the distal connector enables any terminal device to be attached to the connector. The components may be mixed and matched in various combinations to fit the physical dimensions of virtually any amputee. The interchangeable parts will accommodate a wide range of residual limb geometries, overall sizes and lengths. Embodiments of the present invention minimize the need for time and resource-intensive customized fitting and create an affordable, relatively low-cost prosthetic interface. | 04-01-2010 |

20120143109 | Selectively Adjustable Arm and Shoulder Support - A contouring arm and shoulder support is provided that is secured to a supporting and stabilizing belt. The support is interconnected to the belt by an adjustable shoulder component that supports an adjustable arm cuff and provides upward force that moves the patient's shoulder joint out of subluxation. | 06-07-2012 |

20120091398 | ANTI-CORROSIVE TREATMENT FOR SURFACES MADE OF ZINC AND ZINC ALLOYS - The invention refers to a process for producing an anticorrosive coating in which a surface to be treated is brought into contact with an aqueous treatment solution containing chromium(III) ions and at least one phosphate compound and an organosol. The corrosive protection of metal surfaces, in particular those containing zinc and zinciferous surfaces with conversion layers is improved. The decorative and functional properties of the surfaces are retained or improved. In addition, the well-known problems associated with the use of compounds containing chromium(VI) or with multi-stage processes are avoided in which a passivation layer containing chromium ions and a sealing are applied one after the other. | 04-19-2012 |

20130078382 | PROCESS FOR FORMING CORROSION PROTECTION LAYERS ON METAL SURFACES - The invention relates to a process for producing a corrosion-inhibiting coating for substrates having a surface consisting of zinc, magnesium, aluminium or one of their alloys, wherein the surface to be treated is brought into contact in direct succession with two aqueous treatment solutions containing chromium(III) ions, metal ions of the substrate surface to be treated and at least one complexing agent. The first treatment solution has a pH in the range from 1.0 to 4.0, while the second treatment solution has a pH of from 3.0 to 12.0. The process of the invention produces a smaller amount of wastewater polluted with heavy metals. | 03-28-2013 |
