Abstract: A combination of capillary forces and gas pressure is used to control the movement of liquid samples within a microfluidic device. A liquid sample introduced to a proximal portion of a capillary channel of a microfluidic device moves by capillary action partway along the capillary channel. As the liquid sample moves, a pressure of a gas acting upon a distal gas-liquid interface of the liquid sample increases by an amount sufficient to stop further movement of the liquid sample. To initiate further movement of the liquid sample, a pump connected to a distal portion of the capillary channel decreases the pressure of the gas acting upon the distal gas-liquid interface of the liquid sample by an amount sufficient to permit the liquid sample to move by capillary action further along the capillary channel of the microfluidic device.

Abstract: An elliptically interfacing gear assisted braking system may include an input shaft with a coupled input gear, a wobble plate, a rotor with a reaction gear, and an actuated brake mechanism, or brake. The input shaft may define an axis of rotation and the wobble plate may have a wobble axis disposed at a non-zero angle relative to the rotation axis. A set of face teeth disposed on one surface of the wobble plate may partially mesh with the input gear, and a set of wobble teeth on an opposite surface of the wobble plate may partially mesh with the reaction gear. Rotation of the input shaft may thereby cause rotation of the wobble plate and rotor. The brake may mate with the rotor and when actuated, slow the rotor with respect to the input shaft. Rolling contact forces between the surfaces of the wobble teeth and reaction teeth may then induce nutation in the wobble plate, thereby dissipating rotational energy.
