    摘要： A micromachined thermal probe has a substrate with a surface and an edge, and at least one flexible probe body formed on the substrate that includes a cantilever beam section that extends from a proximal end outwardly to a distal end. A pair of conductors in the probe body extend to a junction at the distal end at which is formed a probe tip. Current passed through the conductors to the junction heats the probe tip, with changes in the effective probe resistance occurring as the probe tip is scanned over a sample with different thermal conductivities at different positions. A second flexible probe body may be mounted to the substrate and constructed similarly to the first probe body to act as a reference probe to allow compensation of the first probe. The probe body may be formed of layers of flexible polymer joined together over pairs of conductors, which is bent back onto itself and secured together at a proximal end of the cantilever beam.

    摘要： A micro-electro-discharge machining apparatus includes a substrate, a plurality of electrically conductive electrodes on the substrate arranged in an array, and a plurality of electrical interconnect lines formed on the substrate extending to one or more of the electrodes. An electrical power source is connected from one of its terminals through a resistor to each of the interconnect lines and from its other terminal to a workpiece to be machined. The electrodes connected to different interconnect lines may charge and discharge independently of each other, speeding up the machining process. An interconnect line may extend individually to each electrode so that all of the electrodes can charge and discharge independently of the others. The capacitor that is charged to produce the discharge voltage may be a separate discrete capacitor or a conductive substrate.

    摘要： This invention addresses a contact mode hybrid scanning system (HSS), which can be used for measuring topography. The system consists of a cantilever or a cantilever array, a scanning stage, a light source, and instrumentation to synchronize and control the individual components. Detection of the cantilever's movement is achieved by directly measuring the change in disposition of the cantilever including its height, rotation at one or more points on the cantilever thereby providing a partial three-dimensional reconstruction without the need for actuating the cantilever. This is achieved by employing a displacement meter such as a triangulation meter or a confocal meter.

The apparatus includes a substrate and an anode electrode and a cathode electrode supported on the substrate. One of the electrodes, such as the cathode, is preferably a liquid electrode. The electrodes are spaced apart to define an inter-electrode gap therebetween. The apparatus further includes a voltage source for applying a voltage between the electrodes sufficient to generate a glow micro-discharge in the gap to cause a first emission having a first desired excitation spectrum. An optical element is integrated with the substrate to direct the first emission to travel along an optical path including an axis. In one embodiment, the system detects the direct fluorescence of a sample such as tryptophan and other amino acids. In another embodiment, the system detects fluorescence of dye-labeled biochemicals.
