Abstract: A system and method for using a portable device to communicate with a vehicle to authorize one or more vehicle operations. The portable device may authorize the vehicle to unlock/lock doors, start the vehicle engine, or mobilize the vehicle, or a combination thereof. The vehicle may include a vehicle transmitter system with one or more transmitters disposed at various locations on the vehicle, and the portable device may be configured to monitor a communication strength between the portable device and the one or more transmitters of the transmitter system. Based on the monitored signal strength, the portable device may determine location information about itself.

Abstract: A method for genetically engineering gymnosperm tree species is based on accelerated particle transformation. Tissue of spruce is cultured into an embryogenic callus. Somatic embryos are produced by the callus and then subjected to an accelerated particle transformation process. The treated embryos are then induced to form embryogenic callus cultures and selected for the presence of gene products coded by the introduced genes. Somatic embryos are then induced from the callus and transgenic seedlings are produced.

Abstract: A method of manufacturing a large size tubular cellulosic food casing suitable for being stuffed with a foodstuff without requiring an additional moisturizing step prior to stuffing, comprising the steps of providing a large size tubular cellulosic food casing including a plasticizer substantially uniformly incorporated therein; adjusting the moisture content of the casing to impart to the casing sufficient extensibility and flexibility for the casing to be stuffed without the addition of further moisture prior to the stuffing of said casing, and treating the casing with an antimycotic agent to incorporate a sufficient amount of the antimycotic agent in the casing to render the casing resistant to growth of molds, fungi, and microorganisms prior to the stuffing of the casing with the foodstuff.

Abstract: A generating device for producing a laser energizing gas in the singlet delta, electronic state comprising a vacuum chamber; a tubular reaction chamber positioned within said vacuum chamber, said reaction chamber having a closed end and an oppositely disposed open end; means positioned in said closed end for introducing a flow of a gaseous reactant into said reaction chamber; means positioned adjacent said closed end at an angle perpendicular to the position of said gas introducing means for introducing a stream of a liquid reactant into said gas flow to effect a chemical reaction therebetween and the generation of a laser energizing, singlet delta gas; and means for interconnection to a lasing device for directing a flow of said generated, singlet delta gas to a lasing cavity.

Abstract: Iodine vapor is supplied to an oxygen iodine laser by an improved iodine vaporizer. The vaporizer has a radiation transparent window and iodine crystals are contained in the vaporizer. Broad beam radiation from a variable intensity source is directed through the window into the vaporizer where it is absorbed by the iodine crystals, causing the iodine crystals to sublime. The iodine vapor is transported to the laser by a carrier gas flowed through the vaporizer. Coarse control of the iodine flow is achieved by controlling the carrier gas flow. Control of the amount of iodine vapor introduced into the carrier gas flow is achieved by varying the amount of radiation directed into the vaporizer.
