  • Patent number: 7592281
    Abstract: A composition is provided that includes a plurality of calcined particles of terbium aluminum oxide having a mean particle domain size of between 30 and 600 nanometers. A translucent article having a surface includes polycrystalline terbium aluminum garnet having a mean grain size from 1 to 10 microns and light scattering inclusions of aluminum-rich oxide and/or terbium-rich oxide that are present at less than 2 surface area percent of the surface. A process for forming such an article involves sintering the above provided composition at a temperature between 1500° C. and 1700° C. to yield a sintered article. The article has improved translucency and even transparency as sintering is performed under vacuum at a temperature between 1610° C. and 1680° C. Hot isostatic pressing alone or in combination with article polishing also improves article translucency.

  • Publication number: 20080211306
    Abstract: Methods and systems for supplying power to multiple voltage islands using a single supply source are disclosed. Aspects of one method may include providing power to a first of a plurality of voltage islands, and individually controlling providing of power to each of a remaining portion of the plurality of voltage islands. For example, when an electronic system is first powered on, a low current voltage source may be used to supply power to a primary voltage island. As a higher current voltage source becomes available, power derived from the higher current voltage source may be provided to the primary voltage island and to secondary voltage islands. Power to each of the secondary voltage islands may be, for example, individually controlled via a power MOS transistor. The power MOS transistor may also be configured to allow a faster blocking time than unblocking time.

  • Publication number: 20080099692
    Abstract: Apparatus and accompanying methods for the detection and subsequent destruction or disablement of Improvised Explosive Devices (IEDs) while maintaining a satisfactory level of human safety. Operationally, our inventive method and apparatus detects the IED using one or more methods including: detecting internal battery components; detecting magnetic signature(s) of the IED; detecting a characteristic energy spectrum of the IED; and/or detecting characteristic chemical signatures of the device(s). Once detected, the device may be further characterized and then subsequently deactivated and/or destroyed by a shaped pulse charge directed at the device or its power source (battery) from a safe distance.

  • Patent number: 7337309
    Abstract: A method for securely updating a basic input/output system (BIOS) using a multi-layer scheme. A new BIOS image is received and stored at a computer system. In one embodiment, the new BIOS image is sent to the computer system in a BIOS capsule that also contains the data structure and instructions of how to build a new BIOS image for the computer system. The current BIOS image of the computer system is maintained in a first portion of the BIOS. An access check verifies the integrity of a data structure representation of the current BIOS image. An administration check verifies that proper authority has requested the BIOS update. A checksum is performed on the new BIOS image while writing the new BIOS image to a second portion of the BIOS. Once the new BIOS image passes the multi-layer check, indicia is provided such that the computer system loads BIOS instructions from the new BIOS image on subsequent boots of the computer system.

  • Patent number: 7295978
    Abstract: A system for recognizing speech receives an input speech vector and identifies a Gaussian distribution. The system determines an address from the input speech vector (610) and uses the address to retrieve a distance value for the Gaussian distribution from a table (620). The system then determines the probability of the Gaussian distribution using the distance value (630) and recognizes the input speech vector based on the determined probability (640).

  • Publication number: 20060188991
    Abstract: Herein-described are various methods for making a vaccine that are made of re-assembled virus like particles (VLP). First, the VLPs are disassembled into encapsidation intermediate populations. Each encapsidation intermediate population undergoes, for instance, chemical conjugation of unique peptide or nucleic moieties to form separate populations. Thereafter, a predetermined amount of each of the several (one or more) different encapsidation intermediates from the different populations is mixed and joined, forming intact VLPs, surrounding a nucleic acid core, that are composed of different encapsidation intermediate such that the reassembled VLP displays more than one peptide or nucleic acid. The nucleic acid can function either as a scaffold alone or can be engineered for the expression of an immunomodulatory protein in a eukaryotic cell.

  • Publication number: 20060171527
    Abstract: A driver is operated to drive signals from an integrated circuit. Operating the driver generates interference at substantially a first frequency that may interfere with circuitry sharing a power supply with the driver. A supply node is repeatedly coupled to and decoupled from the driver at substantially a second frequency higher than the first frequency to help supply power to the driver and to help prevent interference from propagating to circuitry sharing the power supply.
