| 20110140133 | LIGHT EMITTING DEVICE HAVING INCREASED LIGHT OUTPUT - The light intensity emitted from a package is increased by adjusting a portion of the package encapsulant so that light impacting the side walls of the adjusted encapsulant portion will encounter total internal reflection (TIR) with the reflected light directed toward the top surface of the package. The adjusted portion of the package is positioned so that air can be used as the second (exterior) medium with the critical TIR angle being such that light emitted from a light source (such as from an LED die) will be directed primarily so as to escape the package from the top surface as opposed to being scattered internal to the package. In one embodiment, a lower portion of the encapsulant is surrounded by a casing to inwardly direct light from the light source that impacts the side of the encapsulant with an angle less than the critical TIR angle. | 06-16-2011 |
| 20100149578 | PRINTER FORMATTER IN A CABLE - A printer cable that is configured for coupling to a printer having an enclosure and a printer port. The printer cable includes a first connector for connecting to the printer port and a second connector for coupling to a host device (e.g., a personal computer (PC)). The printer cable includes a printer formatter for providing formatting services to the printer via the first connector. Since the printer formatter is integrated into the printer cable, the printer formatter is external to the printer enclosure and is easily removable and configurable by a user. | 06-17-2010 |
| 20100139852 | METHOD FOR HIGH-VOLUME PRODUCTION OF LIGHT EMITTING DIODES WITH ATTACHED LENSES - A method for high-volume production of light emitting diodes with attached lenses involves providing pre-fabricated lenses, wherein the pre-fabricated lenses are held by a common transfer structure, simultaneously attaching the pre-fabricated lenses to respective ones of light emitting diodes, and releasing the pre-fabricated lenses from the common transfer structure. In an embodiment, the light emitting diodes are distributed in a pattern on a common substrate and the common transfer structure is configured to hold the pre-fabricated lenses in a pattern that corresponds to the pattern of the light emitting diodes on the common substrate. Further, to attach the pre-fabricated lenses to the light emitting diodes, the common transfer structure is positioned relative to the common substrate such that the pre-fabricated lenses are aligned with the light emitting diodes. | 06-10-2010 |
| 20100066680 | METHODS AND SYSTEMS FOR MEASURING SPECKLE TRANSLATION WITH SPATIAL FILTERS - Two or more spatial filters are used in determining velocity based on speckle translation. A light source may be turned on, turned off, or both for a variable amount of time during operation. The velocity may then be determined with trend identification, correlation, recursive frequency estimation, or measurement bandwidth variation. A confidence level may also be calculated for the measured velocity, and the measured velocity reported or used only when the calculated confidence level meets or exceeds a given value. | 03-18-2010 |
| 20090201108 | Switched Length Match Transmission Path Instrument - A testing apparatus includes one or more trace banks. Each trace bank includes (1) an input switch operable to couple an input port to one of multiple output ports, (2) an output switch operable to couple one of multiple input ports to one output port, and (3) transmission lines of different lengths coupled between the output ports of the input switch and the input ports of the output switch. The trace banks can be cascaded using cables to connect their output and input ports. The input and output switches in the trace banks are controlled to provide a transmission path of the desired length. | 08-13-2009 |
| 20090127446 | Optical Encoder Apparatus for Removable Connection with Printed Circuit Board and Methods of Assembling Optical Encoder - There is disclosed optical encoder apparatus for removable connection with a printed circuit board. In an embodiment, the apparatus includes a light emitting component, a light detecting component, a mounting component for attaching the light emitting component thereon, and another mounting component for attaching the light detecting component thereon, wherein each of the mounting components have a removable connection with the printed circuit board. A method of assembling optical encoder apparatus is disclosed. In an embodiment, the method includes attaching a light emitting component and a terminal of a first mounting component to one another; attaching a light detecting component and a terminal of a second mounting component to one another; attaching a terminal of the first mounting component to a printed circuit board; and attaching a terminal of the second mounting component to the printed circuit board. Other embodiments are also disclosed. | 05-21-2009 |
| 20090061929 | Cell Phone Based Product Research - A cell phone is used to access product information. The cell phone obtains a universal product code (UPC) for a product. A product identifier for the product along with a request for information about the product is sent from the cell phone to a remote site. The remote site obtains the requested information. The remote site sends the requested information to the cell phone. The cell phone communicates the requested information to the user. | 03-05-2009 |
| 20090057542 | ABSOLUTE ENCODER UTILIZING LIGHT OF DIFFERENT WAVELENGTHS TO RECUDE CROSS TALK - An encoder having a code scale, an illumination system, and a plurality of photodetectors is disclosed. The code scale has a plurality of tracks that are illuminated by the illumination system. Each photodetector receives light from a corresponding one of the tracks and generates a signal indicative of a quantity of light received from that track. Each photodetector is limited to detecting light in a band of wavelengths corresponding to that track. Each track generates light in a band of wavelengths corresponding to that track, and the band of wavelengths corresponding to one of the tracks is different from the band of wavelengths corresponding to the tracks that are next to that track. The tracks can include alternating reflective and absorptive stripes, alternating transmissive and reflective stripes, or alternating luminescent and absorptive stripes. | 03-05-2009 |
