Abstract: A scuff and mar-resistant paint composition includes a base paint formulation and a slip additive dispersed in the base paint formulation. Characteristically, the slip additive has a surface energy less than about 30 mJ/m2. Advantageously, the slip additive being in a sufficient amount such that slip resistance of a coating formed from the scuff and mar-resistant paint composition is decreased compared to a coating formed from the base paint formulation. A method of upgrading a manufactured base paint formulation is also provided.

Abstract: An emulsion composition includes an acrylic polymer, a metal silicate, and water. Advantageously, the emulsion composition provides coatings with superior adhesion of coatings to a concrete, clay, or ceramic substrate. In particular, the emulsion composition provides improved adhesion of the silicate primer to the concrete, clay, or ceramic substrate and strong cohesion between the primer and top coat paint allow for a much better overall performance. A method for applying the emulsion composition is also provided.

Abstract: A multilayer coating that provides a switchable color includes a substrate, an electrically conductive heating paint layer disposed over the substrate, a non-electrically conductive paint layer disposed over the electrically conductive heating paint layer, and a thermochromic paint layer disposed over the non-electrically conductive paint layer. The non-electrically conductive paint layer has a base color at 25° C. The thermochromic paint layer has a first preset color at 25° C. and a second preset color at a switching temperature that is higher than 25° C. Characteristically, the first preset color is matched to the base color. A controllable voltage source is in communication with the electrically conductive heating paint layer to switch between a first preset color and a second preset color.

Abstract: A paint composition with reduced seed formation includes a solvent, a polymeric binder, and a plurality of zeolite particles. Characteristically, each zeolite particle defines a plurality of pores therein with an average pore size from about 1 to 100 angstroms and having cations disposed within the pores. Advantageously, the paint composition exhibits reduced seed formation by sequestering cations in the paint composition that tend to cause seed formation.

Abstract: An optical fiber emulator. The emulator receives a digitally-encoded optical signal; demodulates the optical signal to produce serial electrical pulses representative of the digital signal; converts the serial pulses to parallel pulses; propagates the parallel pulses through a shift register whose propagation time is less than or equal to the time of a length of fiber to be emulated. The emulator then converts the parallel pulses at the output of the shift register to serial pulses; modulates an optical carrier with the serial pulses from the shift register; and attenuates the modulated optical signal an amount corresponding to the length of the fiber being emulated to produce an output optical signal whose propagation time is substantially equal to that of a section of optical fiber to be emulated. The shift register may be tapped at any point to obtain an output delayed by a desired amount corresponding to a selected section of optical fiber.

Abstract: A serial differential link glitcher system and method which allow for verification of error recovery by an interfaced or linked architecture system. The system and method provide accurate, reliable, and more assured fault simulation, such as noisy interface and dirty link simulations, within an interfaced or linked architecture system for verification of such error recovery and verifies and checks data at a lower level between interfaced devices. The system and method verify disparity errors between interfaced devices and also perform verification of error recovery between electrically linked devices or optically linked devices. At least two devices are coupled together by communication lines. Normal mode allows for normal operation of and normal communication between the at least two devices, and glitch mode provides fault simulation and disparity errors and phase inversion between the at least two devices for testing error recovery of the system.

Abstract: A redundant power system that includes switch array and component failure detection circuitry is disclosed. The redundant power system includes a plurality of available AC power lines, one of which is coupled to a load through the switch array. A controller instructs the switch array to couple an available AC power line to the load, based upon status information received about the condition of a particular AC power line. Each switch within the switch array includes detection circuitry to determine if the switch has failed, for example, in a stuck closed position.
