    摘要: Providing for a wafer level optical system employing composite lenses is disclosed herein. Conventional focus lens assemblies require three or more lenses. By way of example, two composite lenses can be used to reduce the cost of a wafer-level camera. In some aspects, the composite lenses can be aspheric and can employ a broader variety of wafer materials than earlier designs that only operated in narrow ranges of refractive indices and Abbe numbers.

    摘要: Balloon catheters are prepared to include body affecting chemicals within microcapsules on the exterior of the balloon either alone or with a stent. The coating releases from the balloon when the balloon is inflated into contact with the lumen to be treated. The device provides accurate placement of the dosage required at the location in need of treatment. A sheath may be employed over the balloon and microcapsules to prevent the microcapsules from being rubbed off during delivery through a body lumen. The catheters are especially useful in balloon angioplasty procedures.

    摘要: An optical angle measuring apparatus for measuring the angular displacement of a polygon with light reflecting facets, for use, e.g., in machine tools. The apparatus comprises an autocollimator for projecting collimated light beams onto a facet of a polygon, a matrix array detector for detecting and transducing into angle measuring data the location of the focused light reflected from the polygon facets, a processor and angle error memory unit; for computing the difference between the angles of any given facet and an adjacent facet relative to a respective angle of an ideal regular polygon, and a control unit for processing and compensating for the said angle data to yield a corrected angle measurement. The corrected angle measurement is displayed on display means. A method for measuring the angular displacement of an object relative to a reference position employing the apparatus is also disclosed.
