| 20110264923 | SELF-PROTECTING DIGITAL CONTENT - Technologies are disclosed to transfer responsibility and control over security from player makers to content authors by enabling integration of security logic and content. An exemplary optical disc carries an encrypted digital video title combined with data processing operations that implement the title's security policies and decryption processes. Player devices include a processing environment (e.g., a real-time virtual machine), which plays content by interpreting its processing operations. Players also provide procedure calls to enable content code to load data from media, perform network communications, determine playback environment configurations, access secure nonvolatile storage, submit data to CODECs for output, and/or perform cryptographic operations. Content can insert forensic watermarks in decoded output for tracing pirate copies. If pirates compromise a player or title, future content can be mastered with security features that, for example, block the attack, revoke pirated media, or use native code to correct player vulnerabilities. | 10-27-2011 |

| 20100091982 | DIFFERENTIAL POWER ANALYSIS - RESISTANT CRYPTOGRAPHIC PROCESSING - Information leaked from smart cards and other tamper resistant cryptographic devices can be statistically analyzed to determine keys or other secret data. A data collection and analysis system is configured with an analog-to-digital converter connected to measure the device's consumption of electrical power, or some other property of the target device, that varies during the device's processing. As the target device performs cryptographic operations, data from the A/D converter are recorded for each cryptographic operation. The stored data are then processed using statistical analysis, yielding the entire key, or partial information about the key that can be used to accelerate a brute force search or other attack. | 04-15-2010 |

| 20080307658 | Scissors with a blade having a tapered center for hinge - A scissors is provided. The scissors according to current application has a specially designed first blade. The specially designed first blade has a tapered bump at the central part, on which a hinge hole is developed. The tapered bump on the first blade allow the second blade of the scissors to cross over the first blade with an angle. Therefore, the second blade's wide edge crosses over the first blade's wide edge with an angle and sweeps wide surface of the first blade with an angle. Such angled cross over of the blades provides a more precise cut of customer's hair as a barber intended. | 12-18-2008 |

| 20090149008 | METHOD FOR DEPOSITING GROUP III/V COMPOUNDS - Embodiments of the invention generally relate to methods for forming Group III-V materials by a hydride vapor phase epitaxy (HVPE) process. In one embodiment, a method for forming a gallium nitride material on a substrate within a processing chamber is provided which includes heating a metallic source to form a heated metallic source, wherein the heated metallic source contains gallium, aluminum, indium, alloys thereof, or combinations thereof, exposing the heated metallic source to chlorine gas while forming a metallic chloride gas, exposing the substrate to the metallic chloride gas and a nitrogen precursor gas while forming a metal nitride layer on the substrate during the HVPE process. The method further provides exposing the substrate to chlorine gas during a pretreatment process prior to forming the metal nitride layer. In one example, the exhaust conduit of the processing chamber is heated to about 200° C. or less during the pretreatment process. | 06-11-2009 |

| 20100303414 | CHIP-BASED SLOT WAVEGUIDE SPONTANEOUS EMISSION LIGHT SOURCES - An optical device includes an optically emitting material producing spontaneous emission and an optical waveguide coupled to the optically emitting material. The spontaneous emission from the optically emitting material is emitted into at least one optical mode of the optical waveguide. The optical waveguide coupled to the optically emitting material does not provide optical gain, and the presence of the optical waveguide causes the spontaneous emission rate to be substantially more rapid than in the absence of the optical waveguide. The optical waveguide causes the more rapid spontaneous emission rate over a broad range of frequencies. | 12-02-2010 |
