    Abstract: An electromagnetically actuated hydraulic switch unit is provided by an armature plunger which reciprocally shuttles between partially overlapping magnetic paths and operating a hydraulic valve circuit through bistable snap blade means. Snap blades open and close entry ports, exit ports and vent ports to connect various passages in a housing and perform given hydraulic functions. The ratio of the permeances of the two magnetic paths, created by dedicated coaxial coils, is controlled such that one path always overpowers the other by an amount greater than the mechanical gradients of a pair of snap blades in hydraulic fluid filled cavities, to insure plunger movement in either direction.

    Abstract: An earbud is disclosed for use in a user's ear. The earbud includes an ear pad shaped to engage the concha of the ear and an audio driver coupled to the ear pad. When the earbud is installed in the user's ear the ear pad substantially occludes, or closes up the concha of the user's ear. Thus ambient noise is significantly attenuated before reaching the user's ear canal. Also, the earbud is supported primarily by the ear pad resting in the concha.

    Abstract: Systems and methods are presented that offer significant improvements in the performance of time division duplex (TDD) systems by utilizing an adaptive synchronous protocol. Conventional TDD systems are limited because data is transmitted during discreet and limited intervals of time, and because TDD transceivers may not simultaneously transmit and receive for reasons of insufficiently separated frequencies and limited receiver selectivity. Typically, TDD systems have significant latency due to the time to change from transmission to reception and the propagation delay time. By synchronizing the master nodes and the one or more remotes and by scheduling the traffic loads between these nodes, remote nodes may begin transmitting before the master node is finished with its transmission, and vice versa. This method reduces latency and improves the frame efficiency. Further, the frame efficiency may improve as the distance from the master node to the remote node increases.

    Abstract: A robotic autosampler provides for automated manipulation of microfluidic chips having multiple electrospray devices and/or sample inlets for interface to a mass spectrometer or other detection device. The autosampler also provides for connection of control voltages to the electrospray device to facilitate enablement, control and steering of charged droplets and ions. The autosampler further provides a method of fluid delivery that may be disposable or reusable. The delivery device may contain materials for component separation or sample purification. The delivery device may contain preloaded sample or the sample may be loaded by the autosampler. A method for automated manipulation of multiple electrosprays in communication with a detector, includes: providing a robot autosampler having an electrospray chip; electrospraying at least one analyte from at least one electrospray device on the electrospray chip; and manipulating the electrospray chip in communication with a detector in a manner to detect analyte from the electrospray.

    Abstract: A droplet/electrospray device and a liquid chromatography-electrospray system are disclosed. The droplet/electrospray device comprises a substrate defining a channel between an entrance orifice on an injection surface and an exit orifice on an ejection surface, a nozzle defined by a portion recessed from the ejection surface surrounding the exit orifice, and an electrode for application of an electric potential to the substrate to optimize and generate droplets or an electrospray. A plurality of these electrospray devices can be used in the form of an array of miniaturized nozzles. The liquid chromatography-electrospray device comprises a separation substrate defining an introduction channel between an entrance orifice and a reservoir and a separation channel between the reservoir and an exit orifice, the separation channel being populated with separation posts perpendicular to the fluid flow. A cover substrate is bonded to the separation substrate to enclose the reservoir and the separation channel adjacent the cover substrate. The exit orifice of the liquid chromatography device is homogeneously interfaced with the entrance orifice of the electrospray device to form an integrated single system. Procedures for fabrication of the electrospray devices of the present invention are also disclosed.
