摘要： A method and system for reconstructing an image of a scene comprises configuring a digital light modulator according to a spatially varying pattern. Light energy associated with the scene and incident on the spatially varying pattern is collected and optically focused on the photodetectors. Data indicative of the intensity of the focused light energy from each of said at least two photodetectors is collected. Data from the photodetectors is then combined to reconstruct an image of the scene.

摘要： A method is provided for using a single-pixel imager in order to spatially reconstruct an image of a scene. The method can comprise the following: configuring a light filtering device including an array of imaging elements to a spatially varying optical filtering process of incoming light according to a series of spatial patterns corresponding to sampling functions. The light filtering device can be a transmissive filter including a first membrane, a second membrane, and a variable gap therebetween. The method further comprises tuning a controller for manipulating a variable dimension of the gap; and, measuring, using a photodetector of the single-pixel imager, a magnitude of an intensity of the filtered light across pixel locations in the series of spatial patterns. The magnitude of the intensity can be equivalent to an integral value of the scene across the pixel locations.

The reservoir includes a plurality of vertically arranged chambers. A plurality of piezoelectric transducers is distributed over the chambers in a one-to-one correspondence. At least one electrical conductor is electrically connected to each piezoelectric transducer in the plurality of piezoelectric transducers to enable each piezoelectric sensor to receive an electrical signal to a portion of a wall of the chamber to produce an acoustical wave in the chamber and to transmit an electrical signal from each piezoelectric transducer in response to a fluctuating pressure on each piezoelectric transducer produced by the acoustical wave in the chamber.

摘要： A computer system configured to improve health outcomes and reduce medical service costs includes a memory storing a computer program and a processor that executes the computer program. The computer program receives a medical inquiry, extracts a keyword using natural language processing (NLP), selects a category of concern indicated by the medical inquiry from a library using the keyword, determines leading factors contributing to the category of concern based on a statistical model analysis, selects analytic modules from a library that receive at least one of the leading factors as an input parameter or produce at least one of the leading factors as an output parameter, and generates a recommendation including a listing of the selected analytic modules and/or a constructed workflow including at least two of the selected analytic modules chained together via respective input parameters and output parameters of the at least two selected analytic modules.

摘要： A method and structure for forming an ink jet printhead can include the use of a transfer pad to transfer an adhesive solution to an ink jet printhead substrate. The adhesive solution can be placed within a patterned recess of a cliché and then an upper surface of the adhesive solution can be gelled. A surface of the transfer pad contacts the gelled upper surface and transfers the adhesive solution to the ink jet printhead substrate. During the transfer, a lower surface of the adhesive solution gels. During contact with the ink jet printhead substrate, the gelled lower surface adheres to the ink jet printhead substrate while the gelled upper surface releases from the transfer pad.

摘要： A method, non-transitory computer readable medium, and apparatus for compressive imaging of a scene in a single pixel camera are disclosed. For example, the method moves a pseudo-random pattern media behind an aperture until a pseudo-random sampling function of a plurality of pseudo-random sampling functions is viewable through the aperture, records a value of an intensity of a modulated light from the scene with a detector, wherein the intensity of the modulated light is representative of an inner product between the pseudo-random sampling function and an image of the scene and repeats the moving and the recording until a necessary number of a plurality of inner products are processed.
