A microcomputer interface arrangement includes a microcomputer having I/O ports coupled to individual interface units. A fault detection circuit detects a fault in an interface unit, interrupts the microcomputer and inverts the input state of the faulty unit without affecting the output states so that the faulty unit can be identified by the microcomputer by reading inputs of the interface units.

A polymeric laminate for use with a glass layer in a laminated bilayer or anti-lacerative shield application comprises a first layer of moisture tolerant plasticized polyvinyl butyral containing a) adhesion control agent(s) and b) residual hydroxyl content which optimize glass adhesion and optical performance over a range of moisture contents in the first layer likely to be encountered in use, i.e...

Composite films comprised of an unloaded semicrystalline polyester film support with a roughness Ra no greater than 0.01 mu m having, on at least one of its faces, a coating based on a modified polymer produced by polymerising one or several acrylic monomers in the presence of a water-dispersable sulphonated copolyester. The composite films according to the invention are particularly well suited...

An image processing apparatus for displaying an accumulated image of very faint light emitted from an object superimposed on an image of the object's configuration. Configuration image data representing an external form of an object is stored in advance in a configuration image memory (20).

The stack reflectance is predicted from an on-line, wavelength dependent measurement of the sheet reflectance and the on-line measurement of the sheet opacity at a wavelength interval. The stack reflectance Rst is then used to predict and/or control stack color, preferably by using the parameter K/S=(1-Rst2)/2 Rst where K is the dye absorption coefficient and S is the dye scattering coefficient.

A method for determining the amount of an analyte in a sample fluid utilizing an assay element which comprises at least one reagent layer.
