Abstract: A moving platform roll sensor system comprises an ellipsometric detector capable of detecting a polarized beam within the detector's line-of-sight, and measuring the beam's polarization state, such that the polarization state indicates the rotational orientation of the moving platform with respect to a predefined coordinate system. The ellipsometric detector comprises a venetian blind component through which the polarized beam passes, arranged such that the intensity of the exiting beam varies with its incident angle with respect to the moving platform, a polarizing beamsplitter which splits the exiting beam into components having orthogonal circular polarizations, the relative intensities of which vary with the relative polarization vector of the beam, and first and second detectors which receive the first and second orthogonal circular components and generate respective outputs that vary with the intensities of their received components.

Abstract: A moving object command link system includes a transmitter which outputs a EM beam and a steering mechanism which directs the beam toward one or more objects, at least one of which is moving. The system may include a variable attenuator which modulates the average output power of the beam, and/or a divergence controller to maintain a desired beam size. The beam may be polarized, and the system may include a polarization modulator which changes the beam's polarization in accordance with a predetermined sequence and schedule. The system may include a 1×2 switch to selectively provide the beam to one of first and second outputs. A tiltable dichroic beam splitter may be used to couple beams received from first and second objects to track cameras having respective boresights that are offset with respect to each other.

Abstract: Computer-readable media, computer systems, and computing methods are provided for discovering applications using phone-number information. Initially, an application uploaded to an application marketplace is targeted. Phone numbers associated with the targeted application are discovered by identifying attributes of the targeted application from metadata associated therewith in the application marketplace, and identifying the phone numbers that reach at least one business affiliated with the targeted application or are relevant to the identified attributes of the targeted application. The associated phone numbers are mapped to the targeted application and maintained within an application manifest. Upon detecting user-initiated call-based operation(s) at a client device, the phone number(s) involved in the call-based operation(s) are compared against the application manifest to determine relevant applications.

Abstract: A method of fabricating large area birefringent grating films requires directing a UV beam through a large-scale LC polymer film alignment template on which a predetermined periodic alignment pattern has been imprinted and onto a photo-alignment layer such that the pattern is transferred thereon. The alignment template is fabricated by directing a collimated linearly polarized UV beam through a birefringent prism to produce two UV beams, which are directed onto a photo-alignment layer through a uniform quarter-wave plate to create a UV hologram which imprints the desired pattern onto the photo-alignment layer. These steps are repeated on different portions of the photo-alignment layer to create a large-scale photo-alignment layer.

The polarization state indicates the rotational orientation of the moving platform with respect to the predefined coordinate system. The beam could also be used to convey guidance commands to the platform.

Abstract: A fiber optic sensing system for determining the position of an object requires a light source, an optical fiber, a fiber optic splitter, a fiber tip lens, an optical detector and signal processing circuitry. Light emitted by the light source is conveyed via optical fiber and the splitter to the lens and onto an object, such that at least a portion of the light is reflected by the object and conveyed via fiber and the splitter to the detector. Signal processing circuitry coupled to the detector determines the position of the object with respect to the lens based on a characteristic of the reflected light. The system is suitably employed with a hydraulic accumulator having a piston, the position of which varies with the volume of fluid in the accumulator, with the system arranged to determine the position of the piston, from which the volume can be calculated.

Abstract: Computer-readable media, computer systems, and computing methods are provided for implicitly discovering applications using a query or search results, where the query does not explicitly target a particular application. A search engine is used to receive a user-initiated query and to employ a keyword of the query to generate an initial set of search results. Characteristics of the search results are identified and applications that are relevant to the characteristics are determined. The determination of relevant applications include: accessing an application manifest that manages a mapping between applications and predefined characteristics; comparing the characteristics of the search results against the predefined characteristics of the application manifest to determine a match; and, when a match exists between the search-result characteristics and the predefined characteristics, identifying applications mapped to the matched characteristics as being relevant to the search results.

Abstract: One feature of the present invention uses the parsing capabilities of a structured language model in the information extraction process. During training, the structured language model is first initialized with syntactically annotated training data. The model is then trained by generating parses on semantically annotated training data enforcing annotated constituent boundaries. The syntactic labels in the parse trees generated by the parser are then replaced with joint syntactic and semantic labels. The model is then trained by generating parses on the semantically annotated training data enforcing the semantic tags or labels found in the training data. The trained model can then be used to extract information from test data using the parses generated by the model.

Abstract: Computer-readable media, computer systems, and computing methods are provided for implicitly discovering applications that have a corresponding location. Initially, an application manifest is constructed that maintains a mapping between apps and their respective geographic boundaries. In operation, upon detecting a location signal being transmitted from a mobile device, the location signal is employed to identify a set of valid applications. Generally, the location signal represents location-based information entered to or received from the mobile device. Identifying the set of valid applications involves comparing the location signal against the application manifest and, based on the comparison, designating those apps that are mapped to geographic boundaries that meet the location signal as the set of valid applications.

Abstract: A laser communication and spatial referencing system and related methods provides effective and secure non-line-of-sight communications. A laser communication and spatial referencing system includes a laser transmitter transmitting a pulsed laser beam encoded with binary communications data, and an imaging data receiver for receiving the pulsed laser beam reflecting off a reflective target. The imaging receiver decodes the binary communications data and determines the position of the laser beam. The laser communication and spatial referencing system may operate synchronously and/or asynchronously, and may include a display displaying a video image of area surrounding the target with the reflecting location superimposed on the image to provide visual identification of the target.
