Abstract: Microfluidic devices are described that include a microfluidic channel, a first array of one or more magnets above the microfluidic channel, each magnet in the first array having a magnetic pole orientation opposite to a magnetic pole orientation of an adjacent magnet in the first array, and a second array of one or more magnets beneath the microfluidic channel, each magnet in the second array having a magnetic pole orientation opposite to a magnetic pole orientation of an adjacent magnet in the second array. The first array is aligned with respect to the second array such that magnetic fields emitted by the first array and second array generate a magnetic flux gradient profile extending through the channel. An absolute value of the profile includes a first maximum and a second maximum that bound a local minimum. The local minimum is located within the microfluidic channel or less than 5 mm away from a wall of the microfluidic channel. Methods of using the new devices are also described.

One method includes permitting multiple quotes to be disseminated to the market, but limiting market making to only those entities having a physical presence on the floor of the exchange. Methods of enhancing the hybrid electronic and open-outcry exchange also include automatically eliminating crossed quotes and locked quotes while permitting certain orders to trade against locked quotes.

Abstract: An electric machine including a stator having a fully non-magnetic core and stator windings formed of a non-superconducting transposed conductor to reduce eddy current losses. It further includes a rotor having a fully non-magnetic core and superconducting windings or superconducting magnets which produce a magnetic field for interaction with the stator windings. A cryogenic cooling system is arranged to cool the stator windings to reduce conduction losses in the stator windings.

Abstract: Methods and apparatus for measuring a thickness of a coating on an moving object are provided. Light is directed toward the object at a predetermined location on the object such that a portion of the light interacts with the object. A 1D and/or 2D maximum intensities for at least one wavelength channel is captured that is produced by the portion of the light interacting with the object. A measured average intensity of the wavelength channel and/or intensities and their arithmetic derivatives of multi wavelength channel geometries is converted into 1D (averaged) and/or 2D thickness values. Based on these values an acceptability of the coating is evaluated and thickness calculated.

Abstract: A microfluidic device includes: a first microfluidic channel; a second microfluidic channel extending along the first microfluidic channel; and a first array of islands separating the first microfluidic channel from the second microfluidic channel, in which each island is separated from an adjacent island in the array by an opening that fluidly couples the first microfluidic channel to the second microfluidic channel, in which the first microfluidic channel, the second microfluidic channel, and the islands are arranged so that a fluidic resistance of the first microfluidic channel increases relative to a fluidic resistance of the second microfluidic channel along a longitudinal direction of the first microfluidic channel such that, during use of the microfluidic device, a portion of a fluid sample flowing through the first microfluidic channel passes through one or more of the openings between adjacent islands into the second microfluidic channel.

Abstract: A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.

Abstract: A fail-safe interface for a by-wire vehicle control system merges driver commands and external commands developed by a by-wire control unit to form a failure-tolerant actuator command that never diminishes a driver command. External commands are passed through a fault detection circuit that filters out aberrant cyclical and constant command signals from the by-wire control unit, and the actuator command is determined according to the higher or maximum of the driver-generated and external commands. The interface is powered by vehicle power supply, and is electro-optically isolated from the external control unit so that if the external control unit loses power, the actuator command faithfully follows the driver command.

Abstract: A water pumping system, a motor drive, and a method of starting pumping by the motor drive. The method includes performing repeated starting attempts to overcome stiction in a progressive cavity pump by attempting to supply power to an electrical motor at increasing power levels in each starting attempt and supplying the power at the increasing power levels if the power is available in from a power source; and after each starting attempt: reducing the power applied to the electrical motor to a reduced power level; determining a rotational speed of the electrical motor; determining if the rotational speed matches a speed corresponding to the reduced power level applied to the electrical motor; if the rotational speed does not match and a predetermined number of starting attempts has not been reached, performing a next starting attempt; and if the rotational speed does match, entering a normal mode of operation.

Abstract: The present steerable wheel assembly incorporates a lean-to-steer mechanism into an inner race of a roller bearing, while a wheel is mounted to an outer race of the roller bearing. A shaft extending from the mechanism is attached to a body, and the mechanism acts to steer the outer race and the wheel about a vertical steering axis when the shaft is tilted about a horizontal axis. The mechanism can be a pivot joint, providing a linear steering response, or can be a lean-to-steer mechanism that provides a non-linear response where the steering action is not proportionally responsive to tilting over the expected range of tilting.
