Inventor: TIPTON FREDERICK JAMES
IPC: H05B37/02
Filed: 2007-04-13
Abstract: A gas discharge lamp has a gas and has a cathode, an anode, and an ignition electrode. Individual discharges of a series of lamp discharges are spaced at least one millisecond from each other, and the individual discharges are generated by providing an electrical charge between the cathode and the anode and providing two or more electrical pulses to the ignition electrode. The second and following electrical pulses occur within a predetermined time of the first pulse. The electrical charge between the cathode and anode is of sufficient voltage and current to create an electrical arc between the cathode and the anode with the gas is ionized.

Abstract: A method for manufacturing a surface emitting laser element (1) comprises a step of preparing conductive GaN composite region substrate including a high-dislocation density high-conductivity region (10a), a low-dislocation density high-conductivity region (10b), and low-dislocation density low-conductivity region (10c) as a conductive GaN substrate (10), a semiconductor layer multilayer-body fabricating step of fabricating III-V group compound semiconductor layer multilayer bodies (20) including a light-emitting layer (200) on the substrate, and an electrode forming step of forming a semiconductor-side electrode (15) and a substrate-side electrode (11). The method is characterized in that the semiconductor layer and the electrodes are so formed that the light-emitting region (200a) which is formed in the light-emitting layer (200) and into which carriers flows is in the upper portion of the low-dislocation density high-conductivity region (10b). Thus, a surface emitting laser element where light emission from the light-emitting region is uniform can be produced with high production yield.

IPC: H01M6/04
Filed: 2007-08-10
Abstract: The present invention provides compositions, formulations and methods providing for the effective dissolution of inorganic fluorides in solvents via incorporation of a dissociating agent component. Dissociating agents of the present invention participate in chemical reactions in solution, such as complex formation, acid-base reactions, and adduct formation reactions, that result in enhancement in the dissolution of inorganic fluorides in a range of solvent environments. Dissociating agents comprising Lewis acids, Lewis bases, anion receptors, cation receptors or combinations thereof are provided that significantly increase the extent of dissolution of a range of inorganic fluorides, particularly inorganic fluorides, such as LiF, that are highly insoluble in many solvents in the absence of the dissociating agents of the present invention.

Abstract: The present invention is a method and system for controlling downlink transmission power levels in a spread spectrum time division communication system having frames with time slots for communication, which receives at a user equipment (UE) a downlink communication from a base station and determines an error rate of the received communication. The UE then produces power level adjustments for each of the time slots based in part on the error rate and transmits an uplink communication to the base station which includes the power level. In response to the power level adjustments and (or) other information, transmission power level is set for each time slot in the downlink communication.

Title: Presbyopic vision improvement
Inventor: COX IAN A
IPC: G02C7/04
Filed: 2002-10-18
Abstract: A method of designing a contact lens or other correction for providing presbyopia correction to a patient relies on wavefront aberration measurement data for providing a best form correction. Preferably the correction is in the form of a multifocal translating style alternating vision contact lens or a simultaneous vision style correcting lens. A method for designing a correction for improving a person's vision is directed to correcting higher order aberrations in such a manner that a residual amount of the higher-order rotationally symmetric aberration is greater than a residual amount of the higher-order rotationally asymmetric aberration after the correction. A design method according to the invention is directed to correcting asymmetric higher order aberrations induced by decentering of a multifocal contact lens that has residual spherical aberration which provides increased depth of field.

Abstract: Techniques for sending signaling in a wireless communication system are described. Multiple feedback channels may be multiplexed such that they can share time frequency resources. Each feedback channel may be allocated a different subset of subcarriers in each of at least one tile. In one design, a subscriber station may determine time frequency resources including first and second portions of time frequency resources for first and second feedback channels, respectively. The subscriber station may send vectors of modulation symbols of a first length on the first feedback channel and/or vectors of modulation symbols of a second length on the second feedback channel. A base station may receive the first and second feedback channels and may perform detection on vectors of received symbols for each feedback channel to recover the signaling sent on that feedback channel.

Abstract: In one aspect of the invention a valve that operates in association with a downhole screen is threaded into the wall of a base pipe after being inserted through a saddle. When the valve body is threaded in, the engagement into the wall threads in the base pipe acts as a sealing force on a ring seal between the saddle and the base pipe and between the valve body and the saddle. The valve itself can be outfitted with a cover with openings that can be integral or removable and disposed at the end of the valve that is innermost to the base pipe. Preferably a series of elongated slots are used that can catch slurry if the well is to be killed while allowing subsequent production to drive the accumulated solids from well killing back into the base pipe. Another feature places the valve in a base pipe opening under a cylindrical screen section to reduce assembly time and cost of constructing an adjacent housing to one side of the cylindrical screen section to accommodate the valve.
