A method is described of producing thin layers (below 10 μm in thickness) by directing droplets (preferably by inkjet printing techniques) onto precise locations on a substrate, the liquid of the droplets having a viscosity such that the droplets, on impact with the substrate, spread out to form relics on the substrate that are at least 1.4 times the diameter of the droplets in flight, adjacent droplets merging to form a continuous layer on the substrate. The droplets may have different compositions to form images within the layer. Successive layers may be added to built up a three dimensional structure whose properties can be tailored by the compositions used to build up a composite.

A method and apparatus for processing step-like output signals (primary signals) generated by non-ideal, for example, nominally single-pole ("N-1P ") devices. An exemplary method includes creating a set of secondary signals by directing the primary signal along a plurality of signal paths to a signal summation point, summing the secondary signals reaching the signal summation point after propagating along the signal paths to provide a summed signal, performing a filtering or delaying operation in at least one of said signal paths so that the secondary signals reaching said summing point have a defined time correlation with respect to one another, applying a set of weighting coefficients to the secondary signals propagating along said signal paths, and performing a capturing operation after any filtering or delaying operations so as to provide a weighted signal sum value as a measure of the integrated area QgT of the input signal.

An imaging method provides a flexographic printing member used to transfer ink from an image area to a receiver element. This flexographic printing member has a relief image including an image area that is composed of an elastomeric composition that has an elastomeric topmost surface and a relief image floor. The relief image has a plurality of dots within a sub-area of the elastomeric topmost surface wherein each dot has a minimum receiver element contact area. A fraction less than 1 of the plurality of dots, known as (b) dots, have a topmost surface that is undercut below the elastomeric topmost surface. The (b) dots are undercut below the elastomeric topmost surface in a predetermined number and arrangement so that the (b) dots are still able to transfer ink to the receiver element. Each of the remainder of the plurality of dots in the sub-area, known as (a) dots, has a topmost surface that is essentially coincident with the elastomeric topmost surface.

The invention is directed to an arrangement for the optoelectronic recording of large-area fingerprints, particularly for acquiring prints of the entire palm of the hand. The object of the invention is to find a novel possibility for recording the papillary ridge pattern of a hand which permits a complete optoelectronic image recording with one-time placement of large-area concave skin parts without the use of optical beam paths that are subject to contamination and without having to accept a loss of resolution. This object is met, according to the invention, in that the support body for supporting the skin parts has the basic shape of a cylinder providing a portion of the outer surface with a sufficient radian measure and radius as support surface, the end faces of the support body are each provided with a conical recess which is arranged coaxially around the cylinder axis in order to couple in an illumination beam path and an imaging beam path through the surface lines of the conical recesses, and the imaging beam path and a linearly extending image sensor are rotatable synchronously around the cylinder axis in order to record successive line-shaped strips of the frustrated total reflection at the illuminated outer surface of the support body with the supported skin part.

The present invention is a system and methods of establishing a Melanocyte Protection Factor (MPF), which indicates the level of protection against DNA damage to a target cell, such as the level of protection a particular sunscreen offers against UVA rays when compared to the unprotected case, i.e., no sunscreen. The present invention determines and records levels of stable melanin radicals (SMR) in a target cell. Light is applied to the target cell forming light-induced melanin radicals (LIR). The levels of SMR and intensity of LIR are measured to determine the amount of incident light reaching the target cell. Since LIR is proportional to the square root of light intensity reaching the target cell, the ratio of light reaching the target cell is defined as the MPF: $\mathrm{MPF}=\frac{\begin{array}{c}\mathrm{UV}\mathrm{reaching}\mathrm{melanocyte}\\ \mathrm{without}\mathrm{sunscreen}\end{array}}{\begin{array}{c}\mathrm{UV}\mathrm{reaching}\mathrm{melanocyte}\\ \mathrm{with}\mathrm{sunscreen}\end{array}}=\frac{{\left[\frac{{\mathrm{SMR}}_{+\mathrm{screen}}}{{\mathrm{LIR}}_{+\mathrm{UV}+\mathrm{screen}}}\right]}^2}{{\left[\frac{{\mathrm{SMR}}_{\mathrm{control}}}{\mathrm{LIR}{+}_{\mathrm{UV}\mathrm{control}}}\right]}^2}$

XHD video is acquired from a camera fitted with an ultra-wide field-of-view lens such as a fish eye lens. The active picture portion of the images are divided into patterns each having a plurality of pixels. The patterns are assigned coordinate values and then reformatted into HD format using an encryption key which reorders the patterns. The images are processed in the HD format and then returned to XHD formation by applying the reverse reordering process under the control of the key.
