Abstract: A method and apparatus for protecting an electronic implantable medical device prior to it being implanted in a patient's body. The apparatus affords protection against electronic component damage due to electrostatic discharge and/or physical damage due to improper handling. The apparatus is comprised of a circuit board having conductive surface means for receiving and releasably grasping the electrodes of the medical device to support the device's housing proximate to the surface of the circuit board. First and second conductive paths are formed on the circuit board extending between the first and second conductive surfaces for shunting electrostatic discharge currents to prevent such currents from passing through the device's electronic circuitry. The respective shunt paths include oppositely oriented diodes, preferably comprising diodes which emit light (i.e., LEDs) when current passes therethrough. Additionally, means are provided to enable functional testing of the medical device.

Abstract: Disclosed are uniformly sized domains of liquid crystals, a method for forming the domains, and their performance in polymer dispersed liquid crystal displays. The method provides the ability to form discrete domains of liquid crystal surrounded by a polymer shell, also known as polymer encased liquid crystals, or PELCs. Further, the method provides for the ability to make PELCs that have uniformly sized particles. Displays made comprising uniformly sized PELCs demonstrate markedly improved electro-optical performance over displays made by conventional polymer dispersed liquid crystal processes.

Abstract: Titanium dioxide particles are dispersed in an aqueous medium with a polymeric latex which adsorbs to the surface of the titanium dioxide to give a low-viscosity slurry or pigment grind of composite titanium dioxide-polymeric latex particles. A high glass transition polymeric latex can be used as the dispersant, and a low glass transition temperature binder latex can be added. The zeta potential of the polymeric latex can be at least about 30 millivolts more negative than the zeta potential of the titanium dioxide. The adsorbed polymeric latex provides more optimal spacing of the titanium dioxide particles in films formed from coating compositions formulated using the composite particles, and consequently greater film opacity and hiding at a given pigment volume concentration.

Abstract: Inorganic material particles are dispersed in an aqueous medium with surface charge adjusting additives to give a moderately stable slurry or pigment grind. The dispersion can be used to prepare fully formulated compositions. Products formulated using the aqueous dispersion can be prepared to give the same performance as products including inorganic material dispersed with conventional polyelectrolyte pigment dispersants, but with higher levels of inorganic material, or superior performance properties with like levels of inorganic material.
