Title: Method for producing a waveguide structure in a surface-emitting semiconductor laser and surface-emitting semiconductor laser
Inventor: AMANN MARKUS CHRISTIAN
IPC: H01S5/183
Filed: 2003-11-19
Abstract: The aim of the invention is to produce a waveguide structure in a surface-emitting semiconductor layer having an active zone (3) and a tunnel contact (7) on the p-side of the active zone (3), which borders a second n-doped semiconductor layer (8). To this end, the invention provides that, in a first epitaxial growth process, an n-doped barrier layer (6, 6a) is applied to a p-doped semiconductor layer (5) and is subsequently removed in part whereby forming an aperture (10). In a second epitaxial growth process, the layer provided for the tunnel contact (7) is then applied to the remaining barrier layer (6, 6a) and the aperture (10). By varying the thickness of this barrier layer (6, 6a), the lateral wave guiding and mode selection can be continuously adjusted.

Title: Video game terminal and security activation arrangement
Inventor: PODVOISKI EFIM
IPC: A63F13/77
Filed: 2005-07-29
Abstract: An arrangement for effective updating of video game terminals uses a security key device which is capable of operating next major generation software that at the time of sale or distribution of the security device is not available. Once this software is available, the security key with this forward compatibility to the next major generation of software, allows the owner to update any terminal having the security device. Therefore, existing product, both terminals and/or software upgrades can be sold with the capability for the purchaser to upgrade without return of the security key device. Software can be made generally freely available as it requires a security key device to function. This system is convenient and effective, and allows continued sale of product up to the release of the next major generation of software. The purchaser is buying a next generation key and as such, is buying product that is not about to be replaced.

Title: Method of producing and establishing embryogenic tissue from multiple pine genotypes (genus pinus)
Inventor: PELAYO-ORTIZ CARLOS
IPC: A01H4/00
Filed: 2003-02-28
Abstract: The invention relates to a conifer cloning method which offers the basic essentials in order to provide genetic diversity, said diversity being regarded as the opposite to cloning. The inventive method involves the production and establishment of embryogenic tissue from a wide range of genotypes of selected trees which correspond to species of the Diploxylon and Haploxylon subgenera. Said novel method comprises: the initiation of embryogenic tissue from a wide variety of genotypes, for a period of up to 5 months, of the Diploxylon subgenus; the reinitiation of more than 80 % of the polyembryogenic masses which are produced in vivo and the establishment of almost 90 % of said polyembryogenic masses; the induction of between 50 and 93 % of the embryogenic tissue from the precotyledonary embryos, said percentage being dependent on the tree selected and the quantity of seed used; and, finally, the establishment of 100 % of the genotypes that have proliferated from the Haploxylon subgenus. All of the above is obtained by exploiting the genetic survival capacity of the immature embryos from both subgenera, which enables same to proliferate in any culture medium. The inventive method is based on the principle of not exhausting said capacity in one medium, but rather maintaining the suitable, periodic stimulus when interchanging the embryogenic masses between the culture media used. The advantage of said method lies in the different components from each culture medium used which can be applied alternatively or simultaneously. The media are modified with different ratios and sources of ammonium nitrate, carbon sources and, optionally, a chemical adsorbent or a maturation promoter which are generally used for other purposes.

Abstract: The present invention relates to a method for fabricating a composite gas separation module and to gas separation modules formed by the method. The present invention also relates to a method for selectively separating hydrogen gas from a hydrogen gas-containing gaseous stream. In one embodiment, the method for fabricating a composite gas separation module includes depositing a first material on a porous substrate, thereby forming a coated substrate. The coated substrate is abraded, thereby forming a polished substrate. A second material is then deposited on the polished substrate. The first material, the second material, or both the first material and the second material can include a gas-selective material. For example, the gas-selective material can include a hydrogen-selective metal, e.g., palladium, or an alloy thereof. In one embodiment, the method includes the step of forming a dense gas-selective membrane over the porous substrate. Practice of the present invention can produce gas separation modules that have thinner and/or more uniform dense gas-selective membranes than are possible using conventional manufacturing techniques.

IPC: F02C3/16
Filed: 2004-02-04
Abstract: A trapped vortex combustor for gas turbine engines. An annular combustor housing is provided having a plurality of inlet centerbodies disposed along a helical axis. The inlet centerbodies include a leading edge structure, opposing sidewalls, a pressurizable cavity, and a rear wall. Inlet centerbodies cooperate with adjacent structure and an aft bluff body to define a trapped vortex cavity combustion chamber for mixing an inlet fluid and burning fuel to form hot combustion gases. Mixing is enhanced by utilizing struts adjacent to the rear wall to create eddies in the fluid flow, and by injecting fuel and/or air in opposition to swirl created by the bulk fluid flow. Hot combustion gases are utilized in a turbine for extraction of kinetic energy, or in heat exchange equipment for recovery of thermal energy. High combustion efficiencies and less than 10 ppm emissions of oxides of nitrogen and of carbon monoxide are achieved.

Patent CA-2533498-A1 (CA)
Title: Modulated triangular wave amplifier
Inventor: CHRISTIAN KEVIN
IPC: H03F3/217
Filed: 2004-07-26
Abstract: The invention is a power amplifier circuit for providing a signal acceptable for use in audio amplifiers or similar applications without requiring a stable power supply free from fluctuation. An alternating current power supply signal rectified to a direct current signal is processed by two voltage multipliers (20, 23). A voltage divider (15) establishes a unity gain level, and the variance from this voltage is squared by the first voltage multiplier. This squared voltage is then multiplied with a triangular wave signal to generate a modulated triangular wave signal. The modulated triangular wave signal and a signal to be amplified, typically an audio signal, are processed by an internal comparator (25) to generate a pulse width modulated signal. This modulated signal is processed by a power transistor network (30) and filter (40) to provide an amplified signal to a load device (45). By modulating the triangle wave signal to compensate for fluctuations in the power supply to the amplifier circuit, noise or ripples present in the power supply are demodulated, eliminating the requirement for a regulated power supply.
