IMAGE SENSOR WITH IN-PIXEL BACKGROUND SUBTRACTION AND MOTION DETECTION
20230209216 · 2023-06-29 ·

An imaging system includes a pixel array configured to generate image charge voltage signals in response to incident light received from an external scene. An infrared illumination source is deactivated during the capture of a first image of the external scene and activated during the capture of a second image of the external scene. An array of sample and hold circuits is coupled to the pixel array. Each sample and hold circuit is coupled to a respective pixel of the pixel array and includes first and second capacitors to store first and second image charge voltage signals of the captured first and second images, respectively. A column voltage domain differential amplifier is coupled to the first and second capacitors to determine a difference between the first and second image charge voltage signals to identify an object in a foreground of the external scene.

PROCEDURE FOR OBTAINING FLEXIBLE EXPANDABLE MATERIAL (FEM) RESISTANT TO COMBUSTION USING BIOPLASTIFICIZERS

The present invention is a novel fire-resistant material used for the manufacturing of pipe collars as passive fire protection. The technological process consists of two phases. The first phase involves mixing poly (vinyl chloride-co-vinyl acetate) copolymers (VC-co-VAc) or a modified poly(vinyl chloride-co-vinyl acetate) copolymer (VC-co-VAc) with expandable graphite and plasticizers/modifiers such as: diisononyl phthalate—DINP, dioctyl adipate—DOA, 1-hexadecene or methyl esters of soybean fatty acids (MBS), azodicarbonamide (ADC), tri-p-cresyl phosphate, tri-m-cresyl phosphate or tri-o-cresyl phosphate, epoxidized soybean oil (ESO) and polyacrylate or poly(vinylacetate) emulsion. The second phase considers shaping the resulting mixture in a temperature-controlled press to make various samples, which are further tested. The samples had different dimensions: 4-6 mm thickness, 70-400 mm width and 240-500 mm length.

METHOD AND APPARATUS FOR MANUFACTURE OF 3D OBJECTS
20170369731 · 2017-12-28 ·

The current three-dimensional object manufacturing technique relies on the deposition of a pseudoplastic flame retardant material in gel aggregate state. The gel flows through a deposition nozzle because the applied agitation and pressure shears the bonds and induces a breakdown in the material elasticity. The elasticity recovers immediately after leaving the nozzle, and the gel solidifies to maintain its shape and strength.
