Abstract: According to the disclosure, a target analyte detection cartridge includes a sample chamber into which sample is inserted, a metering chamber connected to the sample chamber to meter a predetermined amount of sample, a mixing chamber connected to the metering chamber to receive a magnet bead, and a waste chamber connected to the metering chamber. The metering chamber has one side connected to each of the sample chamber and the mixing chamber and another side connected to the waste chamber. A first pneumatic flow path to which pneumatic pressure is provided is connected to a waste flow path that joins the other side of the metering chamber to connect the metering chamber and the waster chamber.

Abstract: An accelerator module for an electric vehicle, including a rotor actuator designed to hold a magnet in one end and to provide a drive interface with the vehicle at the other end. The accelerator module employs a Hall Effect chip configured to produce a variable voltage output in proportion to the relative locations of the magnet and the Hall Effect chip, such that when the rotor actuator is caused to rotate, the magnet is rotated across the Hall Effect chip. The Hall Effect chip includes a Hall Effect sensor, which senses differences in magnetic fields. When the magnet is passed across the Hall Effect sensor, the magnetic field will change in proportion to the amount of rotation of the rotor actuator. The variable voltage produced by the Hall Effect chip may then be translated into variable acceleration for the vehicle.

Abstract: An anti-scald apparatus for a tub and shower single control faucet which incorporates a novel cam and cam follower arrangement on the hot and cold water valve means which permits substantially more than 180 degrees of rotation of the control handle. Adjustable temperature stops provide both a comfort stop for normal use and a safety stop which can be reached only by activation of a release button carried by the faucet handle by means of which the comfort stop may be overridden by continuing the rotation of the handle.

Abstract: A frictional control for a single lever faucet construction wherein a compensating cam follower member is made from a material having a higher coefficient of friction than that used for two cam followers which actuate valve members effecting mixing of hot and cold water. All of the cam followers are under the control of a single ball cam member. The cam followers which actuate the valve members have convex surfaces to establish substantially point contact with the ball cam member while the compensating cam follower has a concave surface to engage a substantially larger, and preferably spherical, area of the ball cam member.

Abstract: An all plastic valve construction wherein a removable cartridge contains all wearable seal surfaces. A hollow valve body member is threadedly received in an underbody member and provided with a plurality of separate and distinct sealing locations. The underbody member includes an annular support seat for supporting a plastic stem member in a position only slightly below its assembled position to facilitate the assembly of the stem with a handle for turning same. Two different embodiments are included for stop means which limit the amount of rotation of the stem member relative to the hollow valve body member.

Abstract: A single lever faucet construction utilizing a removable cartridge assembly and improved force balance and friction control on an operating ball cam member. A pair of valve members are mounted in the cartridge in side-by-side relationship with cam follower control means therefor and means to effect vertical adjustment to compensate for both tolerance variations and wear of parts. An underbody member and adapter therefor with three passageway inlets permits the use of a diverter valve and sink spray arrangement in a single installation.
