Abstract: A system for detecting deoxyribonucleic acid (DNA) biomarkers. The system is configured to monitor and control standard parameters (temperature, pH, free chlorine, redox potential, TDS, turbidity), via an array of sensors. The system is configured to perform automated microbiological testing using a DNA hybridization based optical detection sensor, wherein the sensor is configured to provide automated sample collection, primer and buffer addition, thermocycling and fluorescence detection via laser excitation and a linear CCD.

Abstract: A method is provided for maintaining the aggregate stiffness of a pivot bearing assembly generally employed along with an actuator assembly of a magnetic disk drive, while increasing the stiffness in a predetermined direction. More specifically, bearing cartridges used in conjunction with actuator assemblies of the prior art employ at least one ball bearing assembly positioned about a stationary shaft. A modification is presented herein that generally concerns repositioning and maintaining the balls of the ball bearing along a predetermined axis for efficient reaction of loads.
