The movement and mixing of microdroplets through microchannels is described employing silicon-based microscale devices, comprising microdroplet transport channels, reaction regions, electrophoresis modules, and radiation detectors. The discrete droplets are differentially heated and propelled through etched channels. Electronic components are fabricated on the same substrate material, allowing sensors and controlling circuitry to be incorporated in the same device.

Thermal microvalves

A high-performance, compact, finger-operated pointing device comprises a body (), a base (), and return members (). The body has integrated input elements (). Finger-engaging elements () allow operating fingers to move the body and manipulate the integrated input elements simultaneously. Sensors () translate the body's movement to positional control signals to control positions of a computer controlled target. As an isometric device, the magnitude of the positional control signals is mapped to the moving speed of the target.

Low-profile multi-channel input device

The movement and mixing of microdroplets through microchannels is described employing silicon-based microscale devices, including microdroplet transport channels, reaction regions, electrophoresis modules, and radiation detectors. The discrete droplets are differentially heated and propelled through etched channels. Electronic components are fabricated on the same substrate material, allowing sensors and controlling circuitry to be incorporated in the same device.
