Granted: 2005-09-13
Abstract: A brain stimulation lead for precise delivery of electrical stimuli to a small dense brain target, and method of positioning such lead optimally in the patient's brain, is provided. The lead has a distal end portion which is substantially tubular or cylindrical along a longitudinal axis, and has a plurality of electrodes characterized by a diagonal geometry, permitting a greater number of electrodes to be provided within a very small lineal distance, e.g. 10 mm or even 5 mm. In a preferred embodiment, three ring electrodes are positioned on the distal end portion, each at a common angle of about 45 degrees and each extending only about 180 degrees around the lead body. The ring segment electrodes are about 0.5 mm in axial length, and have a separation of about 0.5 mm. The lead also has a tip electrode with a substantially spherical distal edge, and a proximal diagonal edge having the same angle as the ring segment electrodes. The diagonal ring geometry permits fine adjustment of the electrode assembly with respect to the target by simply rotating the lead about its axis, thereby facilitating an optimal electrode placement for precise stimulation of the target.

Abstract: A machine code generating system for improved pattern matching in a protocol analyzer. The code generating system includes a pattern relationship analysis phase and a pattern matching code generation phase. The pattern relationship analysis phase includes evaluating pairs of test patterns to determine the relationship that exists between each pair such as superset, subset, independent, external, and identical. The pattern matching code generation phase includes generating general pattern matching code in addition to generating specialized comparison code that is specific to the types of relationships that exist among a given set of patterns. The machine code that is generated, organizes the patterns into groups to minimize the number of pattern matching comparisons required to a minimum defined in the average case as the sum of the number of patterns and the maximum number of words per pattern. The machine code generated by the code generating system is ready to execute at the completion of the code generating system operation.

Filed: 1998-08-25
Granted: 2001-12-25
Abstract: In recovery type steam-cooled gas turbine, steam passage leading to moving blade is provided on central side of rotor for reducing leakage of steam. Cooling steam 70 of low temperature and high pressure is led into moving blade 1, 2 through supply side steam passage 12, 13 and steam passage 15, 16 and, after used for cooling, flows into cavity 22 through steam passage 16, 17 to be recovered as recovery steam 71 of high temperature and low pressure at rotor end 20 through recovery side steam passage 19, 21. The cooling steam 70 of low temperature and high pressure is led passing on inner side of the recovery steam 71 in rotor, hence there are less places from where the high pressure steam leaks outside as compared with prior art in which the high pressure steam is supplied from outer side in the rotor, and leakage amount of steam is reduced.

Abstract: La présente invention concerne un montage d'annulateur par polarisation adaptative permettant d'annuler tous types de signaux d'interférences concomitants reçus par un récepteur GPS en provenance de sources situées dans le lobe principal et les lobes latéraux de l'antenne. Les composantes à polarisation orthogonale du signal composite reçu sont séparées par le montage d'antenne (5) de réception, puis recalibrées par le réseau adaptateur (7, 9, 15, 17)injectant la polarisation entre l'antenne et le récepteur GPS pour annuler de façon optimale ces composantes. L'interaction entre l'antenne et le montage de l'installation provoque un filtrage par polarisation par rapport aux sources d'interférences, lequel filtrage assure un changement de l'orientation apparente de la polarisation et assure une discrimination adaptative se basant sur une différenciation des caractéristiques de polarisation par rapport aux signaux attendus. Les composantes orthogonales du signal reçu depuis la chaîne de satellites GPS et depuis des sources d'interférences se combinent pour créer, en mode adaptatif, des zéros de croisements de polarisations atténuant de façon appropriée les sources d'interférences tout en modifiant légèrement les signaux GPS reçus. Grâce à une optimisation des polarisations ou une intégration appropriée dans des environnements exempts d'interférences, le réseau de l'invention peut également procurer un meilleur niveau de signal GPS ainsi qu'un meilleur rapport signal/bruit.

Abstract: A process for preparing a PET flake mixture for use in connection with the fabrication of high-performance plastic strapping comprises the steps of initially collecting post-consumer and non-post-consumer PET materials having an initially wide range of relatively low intrinsic viscosity (IV) values with a relatively low average intrinsic viscosity (IV) value and processing the same through solid state polymerization (SSP) so as to obtain a wide range of relatively high intrinsic viscosity (IV) values with a relatively high average intrinsic viscosity (IV) value. The initially collected materials are chopped into flakes and chunks and the chunks are flattened so as to render the remaining mixture comprised substantially entirely of flake materials or segments. This is advantageous because the flake segments, as opposed to the chunk segments, are able to be substantially increased in intrinsic viscosity (IV) values and within a relatively short period of time. The initially collected materials have intrinsic viscosity (IV) values which are within the range of 0.60 - 0.80 dl/g and as high as 0.90 dl/g and the diversity of such materials is underscored or emphasized by the fact that the difference in such intrinsic viscosity (IV) values of the initial or starting materials is at least, or greater than, 0.05 dl/g, is probably at least 0.10 dl/g and can be within the range of 0.10 - 0.30 dl/g.
