Abstract: In an illustrative embodiment of the present invention, a hearing aid device is tethered to a selector module via a cable. A keypad of the selector is pressed to program the hearing aid device with a particular acoustical format. More specifically, a command generated by the selector module is received at the hearing aid test unit to program a corresponding acoustical format. Consequently, a hearing impaired patient can reprogram the hearing aid device to compare which of multiple formats provides an optimal response for use.

Abstract: By combining electro-osmotic and electrohydrodynamic pumps in a microchannel, both polar and non-polar fluids can be moved along said channel. The pumps can be made from pairs of wire electrodes inserted into openings in the channel and connected to a source of a pulsed DC power. By reversing the voltages on alternate pairs of pumps, fluid flow can be reversed, thereby acting as a gate or valve. By using digital drivers, for example shift registers that can apply a signal to a switching device connected to an electrode by means of enabling and latch signals to an AND gate, control of flow in individual channels in an array of channels can be had with a high degree of integration, and provide for ready manufacturability.

Abstract: A system and method for accomplishing a plurality of combinatorial processes in parallel comprising a microelectronic and fluidic array (device array) having micron-sized reservoirs, connecting microchannels and reaction cells etched into a substrate. The device array is supported by a station which serves to interface and perform electro-optic measurements of material in the reaction cells of the device array. The device array incorporates a modular configuration with three distinct layers or plates. The device array comprises a top feedthru plate, a center distribution plate and a bottom cell plate. The three plates are stacked vertically and coupled together to form a liquid-tight seal. Reservoirs, microchannels and reactions cells are controllably etched onto the plates using traditional semiconductor fabrication techniques. The top feedthru plate serves as a cover for the device array and contains apertures selectively positioned above the reservoirs located in the center distribution plate.
