Abstract: The disclosure pertains to a vessel for holding replacement heart valves and associated positioning and installation apparatus which is configured and adapted to contain a biocidal sterilization fluid during and following exposure of a delivery system for the replacement heart valve to sterilization by ionizing radiation and methods of use therefor. The vessel includes a shield which limits exposure of biologically derived material therein to radiation. The vessel also provides a storage and shipping container for the replacement heart valve in which the biologically derived material is maintained in a sterile fluid environment.

Abstract: Apparatus and methods are presented for compensating for offsets in digital-to-analog converters (DACs). An apparatus may comprise a gain block. The non-inverting input of the gain block may be provided with a bias voltage selected to exceed the worst-case expected positive offset of a DAC. Feedback from the output of the gain block may be provided to a processor. The processor may be connected to drive the DAC.

Abstract: A method of reducing the occurrence of ring-sticking in an internal combustion engine in which the crankcase of such an engine is lubricated with a multigrade crankcase lubricating oil composition containing 1 to 15 mass %, based on the mass of the oil composition, of a non-hydrogenated olefin polymer having a number average molecular weight in the range of 100 to 5,000.

Abstract: A system and method for personalizing cards and other secure identification documents. The card personalizing system and method have improved data integrity, system reliability, and system performance. Improvements to card handling and processing within the modules, improved card transfer between modules, improvements to control of the modules, and other improvements are set forth, all of which contribute, individually and collectively, to achieving these goals.
