| 20080201302 | USING PROMOTION ALGORITHMS TO SUPPORT SPATIAL SEARCHES - Computerized methods and systems for performing a search utilizing a spatial index are provided. Upon receiving a search query having a zoom level component (e.g., “Italian Restaurants in Seattle”), a search is initially conducted of the zoom level tags associated with the content items in the spatial index to determine if any of the content items include a zoom level tag indicative of the zoom level component of the search query (e.g., zoom level of city for Seattle). Subsequently, only those content items satisfying the zoom level search are grouped into a primary subset, whereby the primary subset may be filtered by selecting those returned content items with location-based tags that match a location-based component of the query (e.g., Seattle, Wash.). Next, the those content items satisfying the location-based filter are grouped into a location-based subset, which are filtered according to the parsed query components (e.g., category component Italian Restaurants). | 08-21-2008 |

| 20080273560 | Method and Apparatus for Optical Mode Multiplexing of Multimode Lasers and Arrays - According to methods and apparatus described herein, multimode laser source capable of emitting a diffraction-limited beam of various shapes (including single-lobe shape) can be realized. An optical apparatus for generating a such diffraction-limited beam comprises a spatial phase modulator for spatially modulating a spectrally dispersed optical signal emitted from a semiconductor laser into a combined-mode optical signal, wherein the lateral modes of the optical signal from the laser are combined into a diffraction-limited beam. Also, a coupling optical system is provided for wavelength-demultiplexing the multimode optical signal before the multimode optical signal is spatially modulated by the spatial phase modulator, and also for wavelength-multiplexing the combined-mode optical signal. | 11-06-2008 |
| 20110164879 | Compact Multi-Port Optical Signal Processor - In a method and system to fabricate a compact optical device, a periodic group-delay device (PGDD) includes N optical input ports, N being a positive integer number, each port being configured to include one or more wavelength-division- multiplexing (WDM) channels; N corresponding optical output ports, each port being configured to include one or more WDM channels. The PGDD also includes a first slab waveguide region (FSWR) coupled to the N optical input ports, a second slab waveguide region (SSWR) coupled to the said N optical output ports, a first optical grating coupled to the FSWR, a second optical grating coupled to the SSWR, and; a third slab waveguide region (TSWR) coupled to at least one of the first and second optical gratings. The TSWR is configured to provide a configurable amount of dispersion to the N optical output ports. Optical signals carried by each WDM channel are processed concurrently and independently. | 07-07-2011 |
