  • Patent number: 6952478
    Abstract: The present invention provides permutation instructions which can be used in software executed in a programmable processor for solving permutation problems in cryptography, multimedia and other applications. The permute instructions are based on an omega-flip network comprising at least two stages in which each stage can perform the function of either an omega network stage or a flip network stage. Intermediate sequences of bits are defined that an initial sequence of bits from a source register are transformed into. Each intermediate sequence of bits is used as input to a subsequent permutation instruction. Permutation instructions are determined for permuting the initial source sequence of bits into one or more intermediate sequence of bits until a desired sequence is obtained. The intermediate sequences of bits are determined by configuration bits. The permutation instructions form a permutation instruction sequence, of at least one instruction.

  • Patent number: 6936435
    Abstract: The production of a purified extracellular bacterial signal called autoinducer-2 is regulated by changes in environmental conditions associated with a shift from a free-living existence to a colonizing or pathogenic existence in a host organism. Autoinducer-2 stimulates LuxQ luminescence genes, and is believed also to stimulate a variety of pathogenesis related genes in the bacterial species that produce it. A new class of bacterial genes is involved in the biosynthesis of autoinducer-2.

  • Patent number: 6919770
    Abstract: The present invention relates to a method and system for using end resonances of highly spin-polarized alkali metal vapors for an atomic clock, magnetometer or other system. A left end resonance involves a transition from the quantum state of minimum spin angular momentum along the direction of the magnetic field. A right end resonance involves a transition from the quantum state of maximum spin angular momentum along the direction of the magnetic field. For each quantum state of extreme spin there are two end resonances, a microwave resonance and a Zeeman resonance. The microwave resonance is especially useful for atomic clocks, but it can also be used in magnetometers. The low frequency Zeeman resonance is useful for magnetometers.

  • Patent number: 6888780
    Abstract: The present invention provides a method and system to simultaneously use the microwave and Zeeman end resonances associated with the same sublevel of maximum (or minimum) azimuthal quantum number m to lock both the atomic clock frequency and the magnetic field to definite values. This eliminates the concern about the field dependence of the end-resonance frequency. In an embodiment of the system of the present invention, alkali metal vapor is pumped with circularly-polarized D1 laser light that is intensity-modulated at appropriate resonance frequencies, thereby providing coherent population trapping (CPT) resonances. In another embodiment, pumping with constant-intensity circularly-polarized D1 laser light enhances magnetic resonances that are excited by alternating magnetic fields oscillating at appropriate resonance frequencies.

  • Patent number: 6871583
    Abstract: The method of the present invention for handling scrap tires, includes a step of providing a compacting apparatus to a scrap tire generator, such as a tire retailer. Before compacting the tires, the tire can be marked with a unique identifier assigned to every tire generator. By marking the scrap tires with a unique identifier, the scrap tires can be tracked on their way to the final destination. The compacting apparatus provides volume reduction of the scrap tires individually into a form that can have a reduction of at least fifty percent of original cubic volume. The tires can be pinched to maintain the compacted tire in the compacted form and prevent the compacted tire from regaining its original shape. The compacted scrap tires can be accumulated inside a tire collection enclosure, such as a trailer or dumpster. The collected tires can be transported with much more weight efficient loads of the tires to a transfer station, a recycling facility, or an end user.
