Abstract: A composite Fresnel lens useful in an infrared passive detection system includes an array of Fresnel lens segments having a given vertical centerline and a curvature of a given radius. The Fresnel lens segments fall in first and second groups. Each Fresnel lens segment in the first group has a long detection range and a width less than one-third of the diameter of an original whole Fresnel lens from which the segment was taken. Also, each lens segment of the first group has a geometrical center located horizontally from the vertical centerline of the array along the curvature of the array through a circumferential distance less than one-fourth of the radius of curvature of the array. Each Fresnel lens segment in the second group has a short detection range less than the long detection range by a predetermined amount and a width less than one-third of the diameter of an original whole Fresnel lens from which the segment was taken. Also, each lens segments in the second group has a geometrical center located horizontally from the vertical centerline of the array along the curvature of the array through a circumferential distance less than one-half of the radius of curvature of the array. The Fresnel lens segments have respective optical centers which are aligned along the vertical centerline of the array. First and second Fresnel lens segments are aligned along the vertical centerline with the first Fresnel lens segment being the same in width as, being greater in length than, and disposed above, the second Fresnel lens segment. Third and fourth Fresnel lens segments are smaller in both length and width than the first Fresnel lens segment and disposed adjacent to opposite vertical sides of the first Fresnel lens segment offset from the vertical centerline.

Title: Stent delivery catheter system
Inventor: FISCHELL ROBERT E
IPC: A61F2/06
Filed: 1998-03-20
Granted: 2006-08-08
Abstract: The present invention is a stent delivery catheter system for placing a stent within a stenosis in a vessel of a human body. The stent delivery catheter system utilizes a slideable sheath with a thin-walled distal portion that is situated coaxially over a stent that is placed onto a balloon located at the distal portion of a balloon angioplasty catheter. The distal end of a central portion of the sheath has an interior shoulder which is capable of exerting a distally directed push force on the balloon angioplasty catheter at a point that is just proximal to the stent. This push force i5 then transferred through the non-deployed stent to a gradually tapered, highly flexible, lubricity coated distal tip of the balloon angioplasty catheter. The structure of a continuous outer surface extending backward from the distal tip and onto the distal section of the sheath, plus the lubricity coating of the outer surfaces of the distal tip and the sheath, plus the increased stent delivery catheter system pushability provided by the sheath and the stent itself makes it possible for the stent delivery catheter system to be pushed through even very tight stenoses.

Filed: 1996-12-02
Granted: 2002-04-23
Abstract: An improved signal processing method in a signal processor for performing the deconvolution of a signal resulting from an analytical separation process is disclosed. In a first aspect, a signal representing a plurality of partially separated sample zones is measured, a point-spread-function of the signal is determined, and the Fourier transform of the signal and the point-spread-function is taken. Next, a noise component n of the signal is determined and the value of a result signal A(f) is calculated using the following filter A(f) = (D(f)P*(f))/P*(f)P(f) + n , where D(f) is the Fourier transform of the signal, P(f) is the Fourier transform of the point-spread-function, and P*(f) is the complex conjugate of P(f). Finally, the inverse Fourier transform of the result A(f) is taken and reported as A(t). Preferably, the point-spread-function is a Gaussian function having a standard deviation .sigma., where .sigma. is determined using either an .alpha..beta. tracker or the function ..sigma.=(a+bt2)1/2, where a and b are constants. In a second aspect of the invention, a plurality of possible point-spread-functions of the signal are determined and the above-described method is applied using each PSF. The value of the largest point-spread-function which provides a non-negative result is determined, and the associated value of A(t) is reported. In a third aspect of the invention, a program storage device readable by a machine, tangibly embodying a program of instructions executable by a machine to perform the method steps of the first or the second aspects of the invention is provided.

Abstract: An electric vehicle is controlled to conform its operation to that of a conventional internal-combustion-engine powered vehicle. In some embodiments, the charging of the batteries by the auxiliary source of electricity and from dynamic braking is ramped in magnitude when the batteries lie in a state of charge between partial charge and full charge, with the magnitude of the charging being related to the relative state of charge of the battery. The deficiency between traction motor demand and the energy available from the auxiliary electrical source is provided from the batteries in an amount which depends upon the state of the batteries, so that the full amount of the deficiency is provided when the batteries are near full charge, and little or no energy is provided by the batteries when they are near a discharged condition. At charge states of the batteries between near-full-charge and near-full-discharge, the batteries supply an amount of energy which depends monotonically upon the charge state. Charging of the batteries from the auxiliary source is reduced during dynamic braking when the batteries are near full charge. Control of the amount of energy returned during dynamic braking may be performed by control of the transducing efficiency of the traction motor operated as a generator.

Abstract: The present invention relates generally to the field of optical transmission and particularly to a method and a system for controlling optical amplification in wavelength division multiplex optical transmission. WDM systems currently under development will have eighty or more channels, i.e. modulated optical signals with different wavelengths (known as Dense Wavelength Division Multiplexing, DWDM). These DWDM systems are demanding optical amplifiers which, especially considering the cascadation of a plurality of optical amplifiers along the transmission path of the DWDM system, have only very limited tolerances in certain parameters. Among these parameters gain flatness and gain tilt are of special importance. The present invention discloses a method and a system which make use of auxiliary optical signals having a given power level which is equal for all auxiliary signals. Differences in the power levels of the auxiliary signals after optical amplification are used for the control of the optical amplifiers of the WDM system.

Title: Fiber-reinforced composite wrapped steel liner
Inventor: ELLYIN FERNAND
IPC: B29C70/08
Filed: 2000-02-25
Granted: 2003-07-22
Abstract: A steel liner (a pipe or vessel) is wrapped with a stack of sheets of glass fiber-reinforced epoxy matrix composite arranged in angle-ply pattern.  The stack is cured on the liner to bond the sheets together and to the liner.  The wrapped liner is then internally pressurized to cause the liner to yield while the composite remains elastic. When de-pressurized, the liner has compressive residual stress and the composite has tensile residual stress.   When the resulting hybrid structure is subsequently again pressurized, it is found that the elastic regime of the liner has been extended.
