Abstract: A reagent reaction determination method and device applied to a test tube, a computer-readable storage medium and a test tube, wherein, the reagent reaction determination method comprises: outputting a brightness control signal to the light-incident component to control the light-incident component to emit the RGB light, and to adjust the brightness control signal according to a preset step length, so as to adjust the brightness of the RGB light; detecting brightness variations of the light derived by the light-emergent component to generate an electrical signal detection value; perform an interpolation calculation on the present brightness control signal to obtain an estimated value of the brightness control signal when the electrical signal detection value is less than a preset threshold, and determining a reaction result in the reagent reaction chamber according to the estimated value of the brightness control signal. The reagent reaction determination device can greatly improve the user experience.

Abstract: A spectroanalytic system and process for analyzing the absorption properties of highly absorbing viscous materials is disclosed. The measurement probe includes a UV-VIS optical system. A single crystal is shaped so that the light enters the crystal perpendicular to its surface and is Incident on the back face at an angle of 45 degree or greater and the reflected light is collected and channeled to a detector system. This system provides an attenuated total reflectance measurement with minimal reflection points wherein the total path length is comparable with a typically printed offset ink film (0.7-1.3 micron). The total absorption process path length depends only on the refractive index of the chosen crystal and on the angle of incidence of the single reflection. High refractive index materials, like diamond, have path lengths of 50 nm, and an economical material such as cubic zirconium provides a path length of 0.1 micron.

Abstract: A container system includes a container for shipping a parcel and a labeling system for providing information about the shipping of the container, such as to/from information. The container system further includes a closure mechanism for closing the lid of the container, a protection system for protecting the item housed in the container, and a rail system for supporting the container and maintaining its structure.

Abstract: A method of estimating the trap of an overprint of at least two primary colors from the spectral density curve of the overprint by computing the amounts of the two primary colors that will produce a spectral density curve that matches the spectral density curve of the overprint, and then relating the amounts to one another.

Abstract: Methods are disclosed for providing a means for identifying recovered component parts of a destroyed assembly quickly and relatively easily using digital or electronic scanning techniques and comparison to virtual components that are presumed to have constituted the original assembly. The method also provides a means for digitally rigging the component parts in three-dimensional virtual space, thereby minimizing and, in some situations, possibly eliminating any need to physical rig the component parts. The methods include texture mapping a photographic image of a component part onto a representation of the component.
