Abstract: Disclosed herein are methods of tomographic imaging, the methods comprising emitting a beam of light from a light source to a sample and modulating the beam of light through a spatial light modulator configured to convert the beam of light to an Airy beam. The spatial light modulator can be rotatable and positioned at a first angle relative to the sample. The method can further obtain a first perspective view of the sample, rotate the spatial light modulator to a second angle relative to the sample, and obtain a second perspective view of the sample. Each of the perspective views can be generated by the Airy beam interacting with the sample on a focal plane. The method can then reconstruct a volumetric three-dimensional view of the sample using the first perspective view and the second perspective view.

Abstract: In a method of filtering an image from data received from a CMOS camera, image data is loaded by a computational device from the camera. Camera parameters corresponding to the CMOS camera are loaded. Fixed pattern noise associated with the camera is removed based on the camera parameters. A readout noise estimation based on characteristics of the camera and filtering estimated readout noise from the image data is generated. Sparse filtering: selecting sub-frames within the image that have similar features; applying a three-dimensional transform on the sub-frames transforming the sub-frame data into a non-two-dimensional domain and generating a first transformed data set; filtering noise data from the first transformed data set to generate a first thresholded image data set; and applying a reverse three-dimensional transform on the first thresholded image data set so as to generate an image.

Abstract: Disclosed is an endoscopic imaging system, comprising a camera, a plurality of GRIN lenses, a processor, and a memory. Each GRIN optical lens can have a first end configured to be inserted into a cavity of a subject and receive light reflected from a point of interest in the cavity of the patient and a second end configured to transmit the light to the camera. The light can be representative of a distinct image of a perspective view of the point of interest relative to the respective GRIN optical lens. The system can: generate image data corresponding to the light received from each of the plurality of GRIN optical lenses; deconvolve the image data to generate deconvolved image data representative of the distinct images; and generate, using the deconvolved image data, 3D image data representative of a 3D image of the point of interest.

Abstract: A hearing normalization and correction system and process provides accurate correction for users with mild to moderate hearing loss by using actual measured hearing response at multiple sound pressure levels. User measured hearing data is collected at considerably higher resolution and accuracy at multiple sound pressure levels and is automatically converted to multiple accurate correction responses. Dynamic adaptive cross-fade response correction is used to deliver hearing normalization at varying sound pressure levels. Adaptive release response allows the hearing normalization system to accurately track the envelope of the incoming audio signal providing greatly enhanced accuracy and transparency. Adaptive headroom control is also applied to increase both input and output headroom providing professional dynamic range performance. The hearing normalization and correction system delivers audio fidelity and performance transcending that of normal hearing aid technology.

Abstract: In some examples, a method includes receiving a user input string and generating an application password for a particular application from the user input string. Generating the application password may include generating a key for the particular application and specifying a derivation parameter of the application password by applying an indiscriminate selection process to select a character set from multiple character sets for generating the application password. Generating the application password may also include mapping a portion of a hash value of the key and the user input string to characters of the character set selected through the indiscriminate selection process to obtain the application password.

Abstract: The present invention generally relates to super-resolution imaging and other imaging techniques, including imaging in three dimensions. In one aspect, light from emissive entities in a sample may be used to produce polarized beams of light, which can be altered to produce Airy beams. Airy beams can maintain their intensity profiles over large distances without substantial diffraction, according to certain embodiments of the invention. For example, such beams can be used to determine the position of an emissive entity within a sample, and in some embodiments, in 3 dimensions; in some cases, the position may be determined at relatively high resolutions in all 3 dimensions.

And then, the surface of the substrate is processed, for example planarizing the surface of the substrate, to recycle the substrate for repeatedly producing thin single crystal silicons. Therefore, the substrate can be fully utilized, the purpose of decreasing the cost can be achieved and the application can be increased.
