Abstract: A locking quick connect assembly is provided for removably coupling a first tube and a second tube. A quick connect housing presents a central bore for receiving the second tube. A redundant latch component positionable between an unlocked position and a locked position may be provided to slidingly engage the quick connect housing. A twist lock retainer surrounds the quick connect housing and the redundant latch component. The redundant latch component includes an axially extending latch retaining arm and the twist lock retainer includes a locking channel for receiving the latch retaining arm. The twist lock retainer also includes a twist lock retaining arm that locks against a bead of the second tube to resists separation. The twist lock retaining arm extends transversely to and radially inwardly of the locking channel to engage the latch retaining arm to prevent unwanted decoupling of the assembly. A handle extends from the redundant latch component in a direction opposite the latch retaining arm.

Abstract: A method of analyzing a fecal sample containing parasitic material and non-parasitic material. The fecal sample is first deposited into a carrier containing a flotation medium. The carrier is then shaken to disperse the fecal sample in the flotation medium. The fecal sample is then allowed to settle under gravity or by centrifugation. A filter device is then inserted into the carrier to separate the parasitic material from the non-parasitic material and to collect the parasitic material. The collected parasitic material is then poured into a capture filter for analysis.

Abstract: A position sensor generates a signal representative of the angular position and, if desired, angular velocity of a rotating object using only a single circular track and plural brushes that ride on the track when the object rotates. The single circular track can have plural segments, and the sensor can generate more than one signal cycle per revolution.
