Abstract: The present disclosure relates to adjustable stands for supporting a user operated device, such as a compound bow, arrangements for attaching the user operated device to the stand, and/or arrangements for mounting one or more additional accessories to the stand. The stand includes telescoping, height-adjustable leg assemblies and user operable locking arrangements to lock the height of the stand. The arrangements for attaching the user operated device are adjustable to accommodate differently sized user operated devices and provide clearance between the user-operated device and the stand for users of various hand sizes.

Abstract: An automatic clinical analyzer in which the number of cuvette ports available for reaction vessels on a reaction carousel are 50% in a configuration using a single reagent storage areas; in a second configuration an additional reagent storage areas is employed and additional ones of the cuvette ports on reaction carousel are utilized, thereby significantly increasing throughput.

Abstract: A method for determining not to reuse a previously used and cleaned reaction cuvette in an analyzer when an assay scheduled to be performed may be adversely affected by contaminants remaining in the cleaned reaction cuvette. If determined not to reuse a previously used and cleaned reaction cuvette, the previously used and cleaned reaction cuvette is replaced with an unused new reaction cuvette.
