27 Mar 1973TL;DR: The line-emitting phosphors are especially useful because of their distinctive emission characteristics, which provide a vast number of possible combinations of emission which are correlated against the data known about the explosive when it is manufactured as discussed by the authors.
Abstract: Phosphor-explosive material combination and method wherein a small amount of inorganic phosphor is mixed with explosive material to provide an indicia or label of information regarding the explosive, either before or after detonation of same. The phosphor can readily be located with an ultraviolet lamp even after the explosive has been detonated, and by correlating the phosphor emission spectra with data known about the explosive when it is manufactured, the explosive can be identified. Line-emitting phosphors are especially useful because of their distinctive emission characteristics, which provide a vast number of possible combinations of emission which are correlated against the data known about the explosive when it is manufactured. Preferably the phosphor is formed as a combination of finely divided "spotter" phosphor and finely divided "coding" material held together by a binder in the form of small conglomerates, in order to facilitate initial location and later identification of same. There exists a vast number of different combinations of distinctive fluorescent emission, and these can be combined to label any item for later identification.

01 Oct 1976TL;DR: In this article, the authors proposed a method for storing a pulse width modulated wave of predetermined pattern for any discrete value of successive desired output voltage levels, where the notches characterizing a particular pattern are stored in the form of a digital representation one level along several possible levels defining subdivisions of a given time interval which is itself a submultiple of the total duration of the stored quandrant.
Abstract: Pulse width modulation is produced by digital means. Pulse width modulated waves are stored digitally in a memory and retrieved under control of a voltage signal in order to generate a pulse width modulated wave of predetermined pattern for any discrete value of successive desired output voltage levels. Optimal waveforms are selected and stored which extend only for one quadrant but an alteration of the addressing code based on symmetry yields the mirror image of the stored quadrant while sign modification provides symmetry about the abscissa axis. Also, only a single phase is stored and phase shifting by code alteration of the coded information provides the other phases after retrieval. The notches characterizing a particular pattern are stored in the form of a digital representation one level along several possible levels defining subdivisions of a given time interval which is itself a submultiple of the total duration of the stored quandrant. A comparator responsive to a series of ramp signals detects in real time the stored levels thereby to effect switching from one state to the other and define one edge of a notch. The notches may extend over several of the ramp signals. The invention provides, with substantially the same hardware, for a fixed pattern mode of operation in the normal frequency range, and for a free running triangulation mode for the lower frequency range. The invention applies to the field of induction motor drives with adjustable speed.

23 Sep 1980TL;DR: A clear solution is prepared by reacting metal alkoxide with a mixture of critical amounts of water and/or acid in an alcohol diluted medium as mentioned in this paper, which reduces reflectivity on silicon solar cells.
Abstract: A clear solution is prepared by reacting metal alkoxide with a mixture of critical amounts of water and/or acid in an alcohol diluted medium. Alkoxides may be Ti(OR) 4 or Ta(OR) 5 , or another metal alkoxide such as Si(OR) 4 in admixture with these alkoxides. Acids may be HCl or HNO 3 . Quarter wave inorganic optical coatings are deposited by applying the alkoxide solution to a substrate then heating the coating at over 350° C. The coatings reduce reflectivity on silicon solar cells. The index of refraction of the coating can be varied by several techniques, including altering the proportion of titanium and silicon in the coating firing temperature, firing atmosphere. Thicknesses of the coating can be controlled by varying the rpm in spin application, withdrawal rate in dipping application, by concentration of the solution, by the type of solvent or the degree of polymerization of the titanium complexes.

08 May 1995TL;DR: An interferometric synthetic aperture radar (SAR) processing technique, interferometry moving target focusing (IMTF), which is capable of creating clutter suppressed moving ground target images is described.
Abstract: This paper describes an interferometric synthetic aperture radar (SAR) processing technique, interferometric moving target focusing (IMTF), which is capable of creating clutter suppressed moving ground target images. One-meter range resolution data has been processed and is presented. The potential benefit of a moving ground target imaging system, the IMTF processing approach, differences between IMTF and other moving ground target imaging techniques and attributes of the moving target imagery are discussed.
