20080252956 | Optical Pattern Generator Using a Single Rotating Component - An optical pattern uses a single rotating component. The rotating component includes a number of deflection sectors. Each sector deflects an incident optical beam by a substantially constant angular amount although this amount may vary from one sector to the next. The rotating component may be combined with an imaging lens group that produces, for example, image points, spots, or lines displaced along a line locus. | 10-16-2008 |
20080273231 | Optical Scan Engine Using Rotating Mirror Sectors - An optical scan engine includes a rotatable component, for example a disk or drum. The rotatable component includes a plurality of scan sectors that are arranged around the rotation axis and that lie substantially in a plane of rotation. Each scan sector includes a pair of reflective surfaces that typically are radially-facing. The incident optical beam typically propagates along a radial direction (e.g., towards the rotation axis) and each pair of reflective surfaces deflects the incident optical beam by approximately 180 degrees as that pair rotates through the incident optical beam. The deflected optical beam has a virtual image located on the rotation axis. As a result, the real image of the deflected optical beam rotates around the rotation axis at the same angular velocity as the scan sectors. Different scan sectors can be designed to yield diffeent deflections in the axial direction. The addition of a third reflective surface to each scan sector can be used to generate image points that are fixed in space as the scan sector rotates. | 11-06-2008 |
20080291518 | Optical Pattern Generator Using a Single Rotating Optical Component with Ray-Symmetry-Induced Image Stability - An optical pattern generator uses a rotating component that includes a number of deflection sectors containing optical elements. Each sector deflects an incident optical beam by a substantially constant angle although this angle may vary from one sector to the next. The constant deflection angle is achieved by symmetry within the deflection sector, specifically gut-ray symmetry. The rotating component may be combined with an imaging group that produces, for example, image points, spots, or lines displaced along a line locus. The image spots can also be displaced to either side of a line, for example by introducing a tilt in the orthogonal direction or by introducing light beams at various angles to the plane of symmetry. | 11-27-2008 |
20090195848 | Optical Pattern Generators Using Axicon Segments - Optical pattern generators use rotating reflective axicon segments to produce images that can have different dimensions along the pattern direction compared to the cross pattern direction. Examples include both single axicon pattern generators and dual axicon pattern generators that independently control the image space relative aperture and thereby control the image dimensions in two orthogonal directions. | 08-06-2009 |

20080294502 | System and Method for Providing Event-Based Services - A system and method for providing event-based services are disclosed. According to one embodiment of the present invention, merchants and users subscribe with an Event Service Provider (ESP), which includes a server and database. The database maintains information relating to merchant events and subscriber's event preferences. Based on time-sensitive merchant event information, an event is published. Furthermore, the database is queried to determine the preferred subscribers based upon the subscriber's event preferences and the merchant event information relating to the published event. Lastly, an event communication is delivered to the device associated with the preferred subscriber. | 11-27-2008 |
20090248525 | SPREAD ACTIVE MEDIA PLATFORM - Embodiments of the present invention provide a spread active media platform for distributing event-based information in a web-based communication environment. In one embodiment, a system and method for providing event-based services includes storing event information from a merchant, receiving event preference information from registered user. The event preference information may include customized user preferences, or the desired time, date, and/or location for a particular event. Next, the web-based application generates programming code associated with event preference information entered by the registered user. The registered user then transcribes the programming code into at least one electronic information source or device. Based upon a determined match between the transcribed programming code and the stored event information, event content relating to the event is published on the electronic information source or device. | 10-01-2009 |
