Abstract

A tri-layer optical fiber. The fiber has a core which is preferably a single crystal and outer cladding, to reduce signal loss. The cladding process begins with high porosity particles, and is known to introduce porosity in the cladding and at the core/cladding interface. The porosity increases refraction and signal loss. The invention interposes a film layer intermediate the core and cladding. The film layer is sputter coated and preferably of the of same material as the cladding. The film prevents diffusion of the porous cladding into the core, minimizing porosity and improving signal transmission.

Abstract

A method of analyzing and correcting a complex dynamic waveform, such as a radar wave or communication wave. The method comprises dividing a complex waveform into its real and imaginary components, then separately analyzing each such waveform in a dedicated neural to determine respective real and imaginary loss functions as the difference between the actual characteristics and desired characteristics of the mean squared error and at least one of frequency-domain power, time-domain envelope, and frequency-domain phase. The real waveform and imaginary waveform are independently corrected, then recombined into a single corrected complex waveform. These differences are fed into a neural network to improve prediction correction to bring the actual waveform closer to a benchmark waveform. The method of the present invention displays increased accuracy over the prior art without increased computing time or sacrificing notch depth.

Abstract

An image processing system receives a digital image and analyzes the digital image to determine a resolution limit, referred to herein as “feature resolution,” for measuring a metric for features of the image within an acceptable margin of error. Specifically, the system segments a digital image and calculates the error associated with the segmented data when features within a certain range a measured metric (e.g., size range) are removed from the segmented data. This analysis can be repeatedly performed with different cutoff values for the metric until at least a threshold amount of error is reached, thereby indicating a resolution limit at the boundary of an acceptable amount of error.

A method of predicting acute mountain sickness (AMS) at sea level, prior to altitude ascent, that identifies level of AMS risk (no, mild, severe). The method includes collecting a urine sample from a subject and analyzing the urine sample for a quantity of at least one metabolite selected from the group consisting of creatine, taurine, N-methylhistidine, hypoxanthine, 1-methylnicotinamide, 4-hydroxyphenylpyruvate, acetylcarnitine, and 3-methylhistidine. The quantity is compared to a threshold value for the respective metabolite. Based on the comparison, it is determined whether the subject will be susceptible to experience AMS, and its severity, once at high altitude.

Abstract

An actuator element of a MEMS device on a substrate able to create large, out-of-plane deflection includes two separated metallic layers contacting the substrate. The second metallic layer has a first portion contacting the substrate and a second portion having cantilevered over the substrate and first metallic layer. A first insulating layer contacts the cantilevered metallic layer on a bottom contacting surface and a second insulating layer contacting the cantilevered metallic layer on a portion of a top contacting surface. The second, cantilevered portion of the metallic layer is prestressed causing the distal end to deform away from the substrate. Applying a voltage potential between the first and second metallic layers creates an electrostatic field drawing the distal end toward the substrate.

Abstract

A vascular access disassembling needle assembly is provided that enables rapid insertion of a guide wire into the needle and subsequent rapid removal of the access needle off the guide wire by facile disassembly of the needle. The disassembling needle assembly includes a needle portion wherein the needle breaks apart by splitting along at least one seam that extends from the proximal to the distal end to allow removal of the guide wire. Various mechanical features are described that can facilitate the separation of the needle body along at least one seam. Once one or more seams are separated, the needle body may be removed from the guide wire without the need to withdraw the needle along the length of the guide wire, which permits preloading of expanders and other medical devices onto the guidewire.

Abstract

The present invention relates a method of improving a radar system, a module for improving a radar system and an improved radar system that are more efficient than current radar systems and methods of using same. Specifically, in the context of space-time adaptive processing at high angle-doppler resolutions, this advanced radar system utilizes an improved estimator of the interference covariance matrix together with the plug-in whiten-then-match filter. This improvement (a) roughly optimizes the output signal-to-interference-plus-noise, thereby increasing the probability of accurately detecting targets' angular positions and radial velocities, (b) maintains a roughly constant, and thus controllable, false alarm rate, and (c) sometimes associates data preprocessing steps with a Reed-Mallett-Brennan detection loss, providing a guideline for rejecting certain preprocessing steps. Collectively, these advancements signify a considerable leap forward in radar technology.
