20130129983 | SILICON CARBIDE STABILIZING OF SOLID DIAMOND AND STABILIZED MOLDED AND FORMED DIAMOND STRUCTURES - A technique allows diamonds, whether synthetic or naturally occurring, and regardless of shape, to resist high temperatures in an oxidizing environment. This is accomplished by coating the diamond with silicon carbide (SiC). The resulting product may be referred to as SiC-stabilized diamond. A further benefit with respect to diamond jewelry is that by applying SiC to the diamond jewel, a unique pattern is made by small variations in the film thickness. These variations appear under UV and X-ray examination, and along with a unique and invariant weight, provide a unique signature to the jewel. | 05-23-2013 |
20130098865 | ANGLE CONTROL OF MULTI-CAVITY MOLDED COMPONENTS FOR MEMS AND NEMS GROUP ASSEMBLY - A method of making a mold includes forming spaced mold cavities in a mold body. The mold cavities include geometrically similar portions, but have respective depths below an initial reference surface that vary as a function of position along a particular direction. The mold cavities can be formed using anisotropic etching of preferred crystal directions in single crystal materials such as silicon. A portion of the mold material adjacent the initial reference surface is removed to expose a new reference surface at a tilt angle with respect to the initial reference surface. The modified mold cavities have their respective axes at a new desired tilt angle relative to the new reference surface. | 04-25-2013 |
20120092490 | VELOCITY, INTERNAL BALLISTICS AND EXTERNAL BALLISTICS DETECTION AND CONTROL FOR PROJECTILE DEVICES AND A REDUCTION IN DEVICE RELATED POLLUTION - Improvements to projectile devices (particularly air guns) include techniques for measuring and controlling the velocity of projectiles in the barrel and after leaving the barrel, allowing the use of non-toxic projectiles. Tracking of a projectile's flight by its unique sound and/or its unique electromagnetic signal or signal modulation are also provided, along with after-barrel guidance that can be used to improve accuracy. Control for discriminating between authorized and unauthorized users is also provided. A projectile device can also be used for inexpensive and harmless practice using optical and/or acoustic information gathered by targeting and imaging systems built into the device. | 04-19-2012 |
20120089525 | Superconducting Power and Transport System - A transport and power system having a plurality of tubes or tunnels, a magnetic levitation and linear motor train, and a superconducting power cable. One of the tubes can be an escape, power distribution, and maintenance tunnel. These tubes can be above ground, below ground, at ground, or under water. | 04-12-2012 |
20090071055 | Firearm with multiple targeting laser diodes - All or some of the component parts of a firearm are made of synthetic diamond materials. Some firearms include a specially designed trigger capable of verifying a user's identity so that only an authorized user can discharge the firearm. Some firearms include a diamond barrel designed to impart a unique pattern of grooves to any bullet leaving the barrel, thereby facilitating reliable identification of the firearm that fired a particular bullet. | 03-19-2009 |
