  • Patent number: 7723810
    Abstract: To reduce cross-talk between adjacent hot electrodes, the present invention provides a ground plane, which extends beneath each side of a MEMS mirror platform covering opposite edges of a hot electrode along each side thereof. The ground plane includes an overhang section extending between the mirror platform and the hot electrode forming a first gap between the hot electrode and the overhang section, and a second gap between the overhang section and the mirror platform. The method of the present invention enables highly accurate construction using lithographic patterning and deep reactive ion etching (DRIE).

  • Patent number: 7514009
    Abstract: Devices and methods are provided for treating, preventing from growth, and neutralizing microorganisms using high-frequency, low-energy ultrasound. A particular method is provided for treating a fountain solution including simultaneously exposing the fountain solution to gas microbubbles and high-frequency ultrasound. A particular device is also provided, including a compartment for holding a reservoir of fountain solution, a gas microbubble emitter configured to emit microbubbles into the compartment, and a high-frequency ultrasound-emitter configured to emit ultrasound signals into the compartment. The high-frequency ultrasound may be higher than 100 kHz.

  • Patent number: 7359053
    Abstract: An array of optical elements for processing a spatially dispersed optical beam including monitoring optical elements for determining the position of the optical beam in the array is disclosed. The monitoring optical elements have a width that varies in ay direction normal to the array axis, enabling the determination of the beam position across the monitoring elements in both x and y directions. The monitoring optical elements are preferably disposed in the end portions of the array for the beam tilt determination. The optical elements can be e.g. liquid crystal pixels or micro-mirrors.

  • Patent number: 6611642
    Abstract: An optical coupler and method of making an optical filter is disclosed wherein a compound lens having two separate movable lenses are disposed between input/output ports and a filter element, such as a dichroic filter element. The filter is tuned during assembly by varying the gap between the movable lenses. Once it is established that optimum coupling is achieved and a desired wavelength response is achieved, the two lenses are fixed in place.

  • Patent number: 6462306
    Abstract: A material machining system for machining a workpiece (PCB, PWB etc.) for drilling blind vias. The system includes a laser supply system (20, 26, 30) for supplying discrete machining beams (22a, 22b) that are separate from each other. A deflecting devices (28, 32) is provided for deflecting each of the discrete machining beams to generate multiple independent beams at a plurality of positions within a field of operation on the workpiece. A scan lens (34) having an entrance pupil configured to receive the multiple independent beams from the deflecting devices is provided proximate to the entrance pupil of the scan lens. A computer is used for controlling the deflecting devices to change the respective positions of the multiple independent beams in at least one co-ordinate direction within the field of operation. The deflecting devices include galvo/mirror pairs at the entrance pupil of the scan lens. This is accomplished since the scan lens has a relatively large entrance pupil and the mirror parts are small.
