A reprogrammable testing circuit for testing different types of valves may obtain a direction limit for a valve; obtain a test direction input for the valve; determine whether the direction limit of the valve has been reached or when there is an attempt to exceed it based on a current position of the valve, the test direction input, a valve test procedure; run a customized test on the valve in a direction of the direction input based on determining that the direction limit has not been reached; actively comparing the current position of the valve with the direction limit while running the customized test; and discontinue the customized test when the current position of the valve reaches the direction limit.

The present disclosure relates to a composition and a method to prepare a polymer nanoparticle using miniemulsion polymerization (MEP) comprising a monomer, a reactive co-stabilizer and a reactive surfactant. The reactive co-stabilizer as disclosed is a methacrylate containing perfluorinated or semifluorinated side chains like 1H,1H,2H,2H-perfluorodecyl methacrylate (H_(2)F_(8)MA). Further, the reactive stabilizer as used in the preparation is cetyl trimethyl ammonium chloride (CTAB). The polymer nanoparticle as formed has an enhanced stability and low VOC as compared to a pure polymer prepared by MEP.

A method for producing a polymer film of polyvinyl alcohol (PVA) having a high concentration of silver nanoparticles (NPs) includes forming the NPs by drying the forming composition by the process of slow reduction of Ag ions by soft organic reductants. Changing a filling degree of Ag NPs in the film is achieved by displacement of Ag NPs and their seeds generated in the liquid PVA film under the action of a DC current at 2-6 mA. An example metal-polymer film with Ag NPs may be used in stealth technologies, for creating thermophotoelectric (TPE) elements, photo detectors, radiation cooling and heating of optoelectronic devices, in spectroscopy of surface-enhanced Raman scattering (SERS), and for manufacturing LC devices.

A light pen for writing on a polarized light sensitive surface is disclosed. Light emitting diodes emit non-polarized light and a polarization block comprising of a truncated cone shaped collimating optical element, a broad band polarization divider, a broadband semi-wave plate, shifting bi-prism and light beam coupler are built to convert the non-polarized light to be converted to polarized uniform intensity light that is focused using a set of projection lens to a writing surface. The said light pen can be used for creating non erasable writing on many types of articles, documents, and records that would provide verification of authenticity and security.

Methods for removing a material layer from a base substrate utilizing spalling in which mode III stress, i.e., the stress that is perpendicular to the fracture front created in the base substrate, during spalling is reduced. The substantial reduction of the mode III stress during spalling results in a spalling process in which the spalled material has less surface roughness at one of its edges as compared to prior art spalling processes in which the mode III stress is present and competes with spalling.
