摘要： Systems and methods of robust perceptual color identification are disclosed. The methods include a multilevel analysis for determining the robust perceptual color of an object based on observed colors. This multilevel analysis can include a pixel level, a frame level, and/or a sequence level. The determination may make use of color drift matrices and trained functions such as statistical probability functions. The color drift tables and function training are based on training data generated by observing objects of known robust perceptual color in a variety of circumstances. Embodiments of the invention are applicable to the identification and tracking of objects, for example, in a surveillance video system.

摘要： A bi-level structure based on copper metallization technique has been applied to backside of gallium arsenide (GaAs) devices. The foundation where the structure stands on is device substrate backside, on which a layer of diffusion barrier is deposited first, and to the top of it, a layer of copper metallization is plated to enhance device performance. The barrier layer can be selected from tungsten (W), tungsten nitride (WN), or titanium tungsten nitride (TiWN) by sputtering or evaporating, which effectively prevents copper from diffusing into GaAs substrate. The layer of copper metallization, formed by employing anyone of sputtering, evaporating, or electroplating, proves to offer attractive thermal and electrical conductivity and mechanical strength and the like. Moreover, these characteristic improvements coupled with a fascinating part, low cost, would benefit and motivate global GaAs fabs.

摘要： A method for fabricating articles of high-temperature aluminum alloys having a compressional strength of at least 20 kg/mm.sup.2 at temperatures of 300.degree. C. or greater, is disclosed. The method comprises the steps of: (a) forming a porous preform from particles of a first aluminum alloy via cold-pressing, the preform having the shape and dimension of the aluminum alloy article to be fabricated; (b) squeeze-casting a molten second aluminum alloy into void spaces of the porous preform to form an aluminum composite containing the first aluminum alloy, which serves as a reinforcement phase, dispersed in the second aluminum alloy, which serves as a matrix phase; (c) wherein the molten second aluminum alloy is cast at such temperatures so as to cause a surface of the first aluminum alloy particles to melt and thereby form a strong bonding with the second aluminum alloy. The first aluminum alloy particles are formed by melt-spinning, followed by rapid solidification and precipitation, of a composition of the first aluminum alloy to form a thin ribbon, then pulverizing the thin ribbon into particles. Unlike the prior art processes, which fabricate high-temperature aluminum alloys only in essentially two-dimensional articles, the method disclosed herein allows the capability of near net shaping, i.e., it can fabricate high-temperature aluminum alloy articles of essentially any intended shapes. The present process allows selective reinforcement of the fabricated articles to be achieved at strategically important locations, so as to expand the range of engineering applications of the fabricated articles without incurring substantially increased manufacturing cost.

摘要： A method of forming a copper circuit pattern on a ceramic substrate. In accordance with the method, first and second layers of copper oxide and copper are applied to the ceramic substrate. Selected regions of the copper are then masked so that unmasked regions are formed on the copper in a configuration of the copper circuit pattern. Masked regions are formed on the copper adjacent the unmasked regions, where copper cannot be plated. The unmasked regions of the copper are plated in a neutral pH solution by a reverse pulse plating process. The masking is then removed and the copper and copper oxide layers are etched so that the copper and copper oxide is removed from the unmasked regions. Thereafter, the remaining copper is direct bonded to the substrate.

摘要： The present application describes a computer-implemented method and system for obtaining position information for a moving mobile device with increased accuracy and reduced power consumption. The subject of the present application combines information from a GPS location sensor with information from MEMS devices such as an acceleration detector and a gyroscope using statistical analysis techniques such as a Kalman filter to estimate the location of the device with greater accuracy while using numerical methods such as the Newton-Raphson Method to minimize power consumption. Minimizing power consumption is possible because GPS signals sampled at a lower rate can conserve power, while GPS sampled at a lower rate and working together with MEMS devices can achieve the same level of location prediction accuracy as a GPS alone sampled at a higher rate.
