Abstract
The present disclosure relates generally to a taggant system based on adsorbing at least two different metal elements in varying proportions into an inert encapsulating material, wherein the combination of metal elements and/or proportion of metal elements is an identifying marker of the taggant. The taggants can be uniquely identified by the metal elements it contains and/or the quantitation of their relative proportions. The taggants are stable, are quickly and easily identified, do not degrade or interact with the tagged material, can be designed to not degrade in extreme environments, and have a detection based on the emission of electromagnetic radiation that permits detection at trace levels.

Ion trap mass analyzer apparatus, methods, and systems utilizing one or more multiple potential ion guide (MPIG) electrodes

Inventor
Hanson, Curtiss Dwight
Abstract
In one aspect of the invention, an ion trap mass analyzer includes a variable- or multi-potential type ion guide (MPIG) assembly which has been pre-configured to produce a parabolic-type potential field. Each MPIG electrode has a resistive coating of designed characteristics. In one example the coating varies in thickness along the length of an underlying uniform substrate. The MPIG assembly can be a single MPIG electrode or an array of a plurality of MPIG electrodes. An array can facilitate delocalization for improved performance. This chemical modification of a uniform underlying substrate promotes cheaper and flexible instruments. The modified MPIG electrodes also allow miniaturization (e.g. micro and perhaps even nano-scale), which allows miniaturization of the instrument in which the single or plural modified MPIG electrode(s) are placed. This promotes portability and field use instead of limitation to laboratory settings.

Abstract
An apparatus and method for non-contact measurement, with nanometer precision, of surface properties such as the local slope and/or vibration amplitude of a solid material, or the surface tension of a small liquid sample. The apparatus provides a laser light source and optic transmission line adapted to be positioned above and near the sample surface, together with a mechanism adapted to move and/or vibrate or oscillate either the surface or probe, or both, with respect to each other. In turn, an interference pattern by the interaction of reflected light from the surface and light reflected by the terminus, that can be correlated to either: i) the amplitude of vibrations imparted to the surface, or ii) the local slope of the surface as determined in the course of controlled oscillation of the terminus.

Abstract
Method for studying the relationship between the sensitivity of a profile -profile method and the size of the sequence profile, which is defined as the average number of different residue types observed at the profile's positions. Improvements in the sensitivity of a profile-profile method can be made by incorporating a profile dependent scoring scheme, such as position specific background frequencies. The techniques of the present invention are implemented in an alignment algorithm, which when tested against other well established methods for fold recognition, shows increased sensitivity and specificity in detecting remote relationships between protein sequences.

Abstract
A virtual coatings application system has several features to enhance the realism of simulated spray painting. The system generally includes a display screen on which is defined a virtual surface (such as a truck door) that is intended to be virtually painted or coated by the user. The user operates an instrumented spray gun controller that outputs one or more signals representing data as to the status of the controls on the spray gun controller. The system also has a motion tracking system that tracks the position and orientation of the spray gun controller with respect to the virtual surface defined on the display screen. Simulation software generates virtual spray pattern data in response to at least the data from the spray gun controller and the position and orientation data received from the tracking system. Virtual spray pattern images are displayed in real time on the display screen in accordance with the accumulation of virtual spray pattern data at each location on the virtual surface.

Abstract
A blasting system for the removal of coatings or paint from an underlying surface uses an optical device to position the blasting nozzle an appropriate stand¬ off distance from the surface. The blasting media can use a variety of blasting media including abrasives, water, and various specialty blasting media. The preferred optical system is mounted to or integral with the blasting nozzle, and uses a diode laser, a beam splitter and a reflecting mirror to generate a reference beam and a gauge beam. Alternatively, two diode lasers can be used to generate the reference beam and gauge beam respectively. The reference beam propagates in a fixed forward direction, but the direction of the gauge beam is adjustable. The user adjusts the orientation of the gauge beam so that the image of the beam on the surface aligns with the image of the reference beam on the surface when the blasting nozzle is positioned at the appropriate stand-off distance from the surface. Alternatively, the center of the blasting pattern o the surface can be used as a rough estimate for the reference beam, thereby avoiding the need to generate and align two non-parallel beams.
