Abstract: A content extraction system can analyze a network data stream communicated among nodes of a network. The content extraction system can include non-transitory computer storage configured to store at least a portion of the network data stream and a hardware processor in communication with the non-transitory computer storage. The hardware processor can be programmed to access the at least a portion of the network data stream, apply a machine learning technique to the at least a portion of the network data stream to extract an information content, and store the information content in the non-transitory computer storage. In various implementations, the content extraction system can be applied to geographic information services, prescription medication information, or the Internet of Things.

Abstract: Compressive imaging captures images in compressed form, where each sensor does not directly correspond with a pixel, as opposed to standard image capture techniques. This can lead to faster image capture rates due to lower I/O bandwidth requirements, and avoids the need for image compression hardware, as the image is captured in compressed form. Measuring the transformation of an emitted multimodal signal is one method of compressive imaging. Metamaterial antennas and transceivers are well suited for both emitting and receiving multimodal signals, and are thus prime candidates for compressive imaging.

Abstract: Multi-sensor compressive imaging systems can include an imaging component (such an an RF, microwave, or mmW metamaterial surface antenna) and an auxialiary sensing component (such as an EO/IR sensor). In some approaches, the auxiliary sensing component includes a structured light sensor configured to identify the location or posture of an imaging target within a field of view of the imaging component. In some approaches, a reconstructed RF, microwave, or mmW image may be combined with a visual image of a region of interest to provide a multi-spectral representation of the region of interest.

Abstract: An imaging system includes an array of lenses, a plurality of sensor pixels for each lens, the sensor pixels being on an image plane of the imaging system, and a corresponding plurality of focal plane coding elements. A focal plane coding element for each sensor pixel has multiple sub-pixel resolution elements. The focal plane coding element being between the lens and each sensor pixel, wherein sub-pixel resolution elements over the plurality of focal plane coding elements represent a selected transform matrix having a non-zero determinant. The output of the plurality of sensor pixels being an image multiplied by this matrix.

Abstract: Among other things, in one aspect, an apparatus comprises features to enable mounting first and second jetting assemblies on a frame. The features comprise first and second alignment datums pre-fixed with respect to the frame for establishing respective positions of the first and second jetting assemblies, when mounted, so that at least some of the nozzles along a length of one of the jetting assemblies have predetermined offsets relative to at least some of the nozzles along a length of the other of the jetting assemblies, and an opening exposing all of the nozzles along the lengths of the first and second jetting assemblies are exposed to permit jetting of a fluid onto a substrate.

Abstract: Systems and methods for automatically polling for data changes in an on-demand database service environment. A polling server communicates with application servers and client systems. Application servers send update messages to the polling server identifying which database objects have been updated, and client systems communicate with the polling server on a regular basis, rather than with the application server, to determine whether updates to a data object may have been made. When it has been determined that an update may have been made, the client system then sends a refresh request to the application server to request an update to the data object, thereby controlling (e.g., reducing) the number of refresh requests sent to the application server.

Abstract: The present invention relates to systems and methods for compiling communication material across a range of formats. A first aspect of the present invention relates to a method of editing an image for printing. The image data for a high resolution image is stored and the image is displayed at a lower resolution. The user can then edit the displayed image and image modifier data is generated based on the editing performed by the user. The image modifier data is subsequently applied to the stored high resolution image data and a modified version of the image is output based on said modified high resolution image data. The present invention also relates to a system and method for monitoring an electronic file. Furthermore, the present invention relates to a system and method of sharing data across a range of different templates for online and print material. The invention also relates to a system and method of generating online and print material in a common file format.

Abstract: A class of aperture coded spectrometer is optimized for the spectral characterization of diffuse sources. The instrument achieves high throughput and high spatial resolution by replacing the slit of conventional dispersive spectrometers with a spatial filter or mask. A number of masks can be used including Harmonic masks, Legendre masks, and Hadamard masks.

Abstract: A transmission mask or coded aperture is used in spectroscopy to compressively sample an optical signal. The locations of transmissive and opaque elements of the mask are determined by a transmission function. The optical signal transmitted by the mask is detected at each sensor of a plurality of sensors dispersed spatially with respect to the mask. A number of estimated optical signal values is calculated from sensor measurements and the transmission function. The optical signal is compressed by selecting the transmission function so that the number of measurements is less than the number of estimated optical signal values. A reconstructed optical signal is further calculated using signal inference. An imaging system created from plurality of encoded subimaging systems compressively samples an optical signal.
