  • Patent number: 8677931
    Abstract: A pattern having exceptionally small features is printed on a partially fabricated integrated circuit during integrated circuit fabrication. The pattern is printed using an array of probes, each probe having: 1) a photocatalytic nanodot at its tip; and 2) an individually controlled light source. The surface of the partially fabricated integrated circuit comprises a photochemically active species. The active species undergoes a chemical change when contacted by the nanodot, when the nanodot is illuminated by light. To print a pattern, each probe raster-scans its associated nanodot across the surface of the partially fabricated integrated circuit. When the nanodot reaches a desired location, the nanodot is illuminated by the light source, catalyzing a change in the reactive species and, thus, printing at that location. Subsequently, reacted or unreacted species are selectively removed, thereby forming a mask pattern over the partially fabricated integrated circuit.

    Abstract: A fluorometer comprising an excitation system including an excitation source for producing excitation light capable of causing fluorescence in fluorescent material; and a detection system for detecting said fluorescence. The excitation source comprises one or more light emitting diodes (LEDs) associated with means for causing said excitation light to form a beam that projects, during use, from the fluorometer. In one embodiment, the excitation system and the detection system are located in respective separate housings, the angular disposition between the housings being adjustable. In other embodiments, the excitation system and the detection system are located in the same housing. The fluorometer is particularly suited for use in detecting leaks in aqueous environments, especially when mounted on an underwater vehicle.

  • Patent number: 7322723
    Abstract: An illumination device has an illumination means formed by an arrangement of a plurality of semiconductor light sources (2) grouped together to form a field. Sensor elements (3) are arranged at individual positions of the field instead of the semiconductor sources (2). A multifunctional headlight can thus be advantageously created. The headlight can be embodied as a robust, compact, low-space unit. By virtue of the fact that the light sources (2) and the sensor elements (3) do not necessarily use the same lens system (1) i.e. each individual element of the multifunctional headlight can be provided with an individually designed lens system (1), the beam path of the illumination device can be separated from the field of vision of the sensor system and can thus be determined independently over large areas.

    Abstract: An optical alignment method is for an optical module including a housing unit, a light-sensing unit, and a lens unit. The method includes: (a) through image-capturing techniques, finding a light-sensing component of the light-sensing unit and a predetermined reference point, and determining an actual total optical path length between the light-sensing component and an object position; (b) subtracting a correction distance from the actual total optical path length to obtain a corrected total optical path length; (c) finding a first center line that divides the corrected total optical path length in half; (d) through image-capturing techniques, finding opposite first and second edges of the lens unit, and determining a lens length between the first and second edges; (e) finding a second center line that divides the lens length in half; and (f) assembling the lens unit to the housing unit such that the first and second center lines overlap.

  • Patent number: 7161585
    Abstract: There is described a method of post-processing and reporting detected displacement in an optical pointing device as well as a sensing device for an optical pointing device implementing this method. Displacement is detected and a first count representative of a magnitude of the detected displacement is accumulated in an associated accumulation unit, this first count representing the magnitude of the detected displacement at a first resolution (or detection resolution). The first count accumulated in the accumulation unit is processed to convert this first count into a report count representing the magnitude of the detected displacement at a second resolution (or reporting resolution) lower than the first resolution. This report count is then reported, for instance to a PC or an external controller. These operations are repeated to generate periodic motion reports at the second resolution.
