20110033957 | INTEGRATED THIN FILM METROLOGY SYSTEM USED IN A SOLAR CELL PRODUCTION LINE - Embodiments of the present invention generally relate to systems, apparatuses, and methods used to form solar cell devices using processing modules adapted to perform one or more processes in the formation of the solar cell devices. In one embodiment, the system provides an inline inspection system of solar cell devices within a solar cell production line while collecting and using metrology data to diagnose, tune, or improve production line processes during manufacture of solar cell devices. In one embodiment, the inspection system provides an on-the-fly characterization module positioned downstream from one or more processing tools wherein the characterization module is configured to measure on-the-fly one or more properties of one or more photovoltaic layers formed on a substrate surface and a system controller in communication with the characterization module and the one or more processing tools, where the system controller is configured to analyze information received from the characterization module. | 02-10-2011 |
20110199476 | METROLOGY SYSTEM FOR IMAGING WORKPIECE SURFACES AT HIGH ROBOT TRANSFER SPEEDS - A metrology system has an elongate stationary camera pixel array facing a workpiece transit path of a robot with an field of view corresponding to a workpiece diameter and extending transverse to the transit path portion, and a stationary elongate light emitting array generally parallel to the pixel array. An image control processor causes the camera to capture successive image frames while the, robot is moving the workpiece through the transit path. | 08-18-2011 |
20110199477 | METHOD FOR IMAGING WORKPIECE SURFACES AT HIGH ROBOT TRANSFER SPEEDS WITH REDUCTION OR PREVENTION OF MOTION-INDUCED DISTORTION - A method is provided for imaging a workpiece by capturing successive frames of an elongate stationary field of view transverse to a workpiece transit path of a robot, while the workpiece is transported by the robot. The robot transit path is illuminated with an elongate illumination pattern transverse to the transit path to obtain a workpiece image of successive frames. Motion-induced image distortion is prevented or reduced adjusting the camera frame rate in real time in proportion to changes in robot velocity profile of the workpiece along the transit path. | 08-18-2011 |
20110200247 | METHOD FOR IMAGING WORKPIECE SURFACES AT HIGH ROBOT TRANSFER SPEEDS WITH CORRECTION OF MOTION-INDUCED DISTORTION - A method is provided for imaging a workpiece by capturing successive frames of an elongate stationary field of view transverse to a workpiece transit path of a robot, while the workpiece is transported by the robot. The robot transit path is illuminated with an elongate illumination pattern transverse to the transit path to obtain a workpiece image of successive frames. Motion-induced image distortion is corrected by computing respective correct locations of respective ones of the frames along the transit path. | 08-18-2011 |

The impedance matching transmission line structure is characterized by a section geometry and a predetermined matching impedance. The predetermined matching impedance is a function of the section geometry and at least one performance parameter of the device is a function of the predetermined resonator geometry. | 05-06-2010 |
20100259336 | SURFACE MOUNTABLE CIRCULATOR - The present invention is directed to a surface mountable circulator/isolator device that includes a first dielectric layer having an electric circuit formed thereon. A second center dielectric layer is disposed adjacent the first dielectric layer, the center dielectric layer including an opening formed therein, the opening being aligned relative to the electric circuit. A ferrite element is disposed in the opening such that the ferrite abuts the electric circuit and is aligned in two-dimensions relative to the electric circuit. A third dielectric layer is disposed adjacent the second center layer. The third dielectric layer includes a ground plane formed on each major surface thereof. The first dielectric layer, the second center dielectric layer, the ferrite element, and the third dielectric layer are bonded together to form a laminated multi-layer structure. A permanent magnet is bonded to the second ground plane. | 10-14-2010 |
20120103169 | Magnetic Instrument Pickup - An instrument pickup including a stack of thin laminated printed circuit boards. Each layer includes an etched coil conductor structure with narrow lines and spaces defining the coil structure. The layers are connected via through holes. The etched lines are smaller than the insulated copper wire (also sometimes called magnetic wire) of a conventional instrument pickup, which means that the size, volume and/or height of the pickup may be reduced relative to a conventional wire wound instrument pickup. | 05-03-2012 |
20120272815 | Magnetic Instrument Pickup - Various improvements and configurations for magnetic musical instrument pickups. Many of the embodiments discussed herein include printed circuit board (pcb) coils, but other embodiments may involve conventional wire wound coils. In some embodiments, the coils (pcb and/or wire wound) are encased in rigid encasement material (see DEFINITIONS section) to reduce microphony and make a quieter pickup. Also, the use of pcb coils allows for many and various new coil shapes and/or configurations because the footprint and stacking of pcb traces are relatively easy to control and/or change. Also disclosed are electromagnetic field interference reduction techniques and integration of multiple coils directly into a single pcb substrate and/or scratchpate. Also disclosed is the use of Hallbach biasing magnet arrays in connection with wire wound and/or pcb coils. | 11-01-2012 |
