Title: Ptfe window seal with emi shielding
Inventor: SMITH DENNIS J
IPC: G01F23/292
Filed: 1999-11-10
Abstract: A process seal (30) made of a material such as polytetrafluorethylene is used as a microwave window (31) in a radar tank level gauge (16). The periphery (32) of the process seal is surrounded by a metal containment ring (40) that is fitted to the periphery to limit the amount of expansion outwardly of the process seal material as well as provide for localized loading at the periphery for clamping pressures on the seal (30). Electromagnetic radiation shielding is provided not only by the containment ring (40), but also by an EMI shielding O-ring (46) mounted in a groove on a sealing end of the containment ring. A process environmental O-ring (41) is carried by the process seal (30) in an outer shoulder groove that is enclosed by the containment ring (40).

Title: Method and apparatus for performing rate determination using orthogonal rate-dependent walsh covering codes
Inventor: BLACK PETER J
IPC: H04B1/707
Filed: 1999-02-03
Abstract: A method and apparatus for rate determination in a communication system using orthogonal rate-dependent Walsh covering codes. Orthogonal rate-dependent Walsh codes are used to cover repeated code symbols prior to transmission over a communication link. The Walsh codes comprise orthogonal binary codes that increase by powers of two for each data rate in the system. Code symbols are repeated and then covered at the symbol rate using the inventive orthogonal Walsh codes. The symbol error rate (SER) blocks are used to generate rate-dependent SER metrics for each of the candidate rates. SER estimators (230, 232, 234, 236) associated with soft combiners (204, 206, 208, 210) using incorrect data rate hypotheses produce high symbol error rates with respect to the symbol error rate produced by the SER estimator (230, 232, 234, 236) associated with the soft combiner (204, 206, 208, 210) using the correct rate hypothesis. In another embodiment, energy metric calculators (250, 252, 254, 256) are substituted for SER estimators (230, 232, 234, 236) and used to generate rate-dependent re-encoded energy metrics for each candidate data rate. The energy metrics produce an estimate of the symbol energy, and the symbol energy is used as a data rate indicator.

Filed: 1999-03-19
Abstract: A system and method for treating atrial fibrillation using atrial pacing pulses to convert an atrial fibrillation to non-fibrillation atrial arrhythmia prior to delivering a low energy cardioversion/defibrillation shock. The system and method treats atrial fibrillations by first applying a plurality of pacing pulses to the atria which converts the atrial fibrillation to non-fibrillation atrial arrhythmia. Ventricular intervals are concurrently sensed and analyzed while the plurality of electrical pacing pulses are being applied. Upon detecting a period of stable ventricular intervals, the system then proceeds to deliver a low-energy cardioverting/defibrillating pulse of electrical energy across the atria of the heart.

Title: Bandes supraconductrices
Inventor: ZHAO RUPENG
IPC: H01L39/14
Filed: 1999-03-18
Abstract: L'invention concerne une bande supraconductrice composite comprenant plusieurs bandes supraconductrices (12) de constituant, empilées parallèlement les unes sur les autres, les faces principales étant en contact, et caractérisée en ce qu'au moins certaines bandes de constituant (12) présentent des largeurs inférieures ou égales à la moitié de la largeur du supraconducteur composite et sont disposées bord à bord. Toutes les bandes supraconductrices de constituant présentent, de préférence, une largeur égale à la moitié, ou à une autre fraction simple, de la largeur de la bande composite, de sorte qu'elles forment deux ou plusieurs sous-piles (15) avec des zones alignées entre elles, qui ne contiennent pas de matériau supraconducteur. De ce fait, il est nécessaire d'ajouter une bande pleine largeur (13) d'argent ou d'un alliage d'argent de façon à établir une passerelle de bande à bande, ce qui établit une connexion mécanique suffisamment forte entre les sous-piles (15). Des expériences préliminaires indiquent que cette structure possède un courant critique sensiblement amélioré en comparaison d'une pile de mêmes dimensions globales ainsi qu'une composition avec des bandes supraconductrices pleine largeur. On suppose que cela est dû à un découplage magnétique entre les sous-piles.

Title: Methods of forming protein-linked lipidic microparticles, and compositions thereof
Inventor: PAPAHADJOPOULOS DEMETRIOS
IPC: A61K48/00
Filed: 1999-05-11
Abstract: The present invention provides for lipid:nucleic acid complexes that have increased shelf life and high transfection activity in vivo following intravenous injection, and methods of preparing such complexes. The methods generally involve contacting a nucleic acid with an organic polycation to produce a condensed nucleic acid, and then combining the condensed nucleic acid with a lipid comprising an amphiphilic cationic lipid to produce the lipid:nucleic acid complex. This complex can be further stabilized by the addition of a hydrophilic polymer attached to hydrophobic side chains. The complex can also be made specific for specific cells, by incorporating a targeting moiety such as a Fab' fragment attached to a hydrophilic polymer. The present invention further relates to lipidic microparticles with attached proteins which have been first conjugated to linker molecules having a hydrophilic polymer domain and a hydrophobic domain capable of stable association with the microparticle, or proteins which have been engineered to contain a hydrophilic domain and a lipid moiety permitting stable association with the microparticle.

Abstract: In radiotherapy, a high quality imaging array may be placed after the patient and opposite the radiation source to be used during radiation treatment to verify operation of a shutter system or similar device and/or to compute dose delivered to the patient. A model of the patient may be used and inverted in order to estimate values of energy fluence prior to absorption by the patient and overlapping of the various radiation beams passing through the patient. A  test pattern of shutter excitation to illuminate a single ray at a time provides a simple method of obtaining the necessary model. The dose from this test pattern may be subtracted from the subsequent radiation treatment so as to provide limited or no increase in total dose to the patient.

Abstract: There is provided a driving force control system for a four-wheel drive vehicle, which is capable of preventing occurrence of a tight-turn braking phenomenon by relatively simple construction to thereby reduce the manufacturing cost thereof, and at the same time, enhancing the response of slippage-eliminating control on main drive wheels, and stability of the vehicle. The 2/WD .cndot. ECU of the driving force control system 1 controls electromagnetic clutches of a four-wheel drive vehicle having front wheels as main drive wheels and rear wheels as auxiliary drive wheels, whereby the LSD torque to be distributed to the rear wheels is controlled. More specifically, the front-wheel/rear-wheel slip ratio is determined from the average front wheel speed and the average rear wheel speed, and the left/right rear-wheel speed ratio and the front-wheel/rear-wheel slip ratio threshold are determined according to the rear wheel speeds, and a first LSD torque for use in calculation of the LSD torque is determined based on the difference between the front-wheel/rear-wheel slip ratio and the front-wheel/ rear-wheel slip ratio threshold.
