Publication number: 20250111118Abstract: Provided are methods and apparatus that provide for removing unnecessary configuration information from the bitstream to configure a field programmable gate array (FPGA) using a reduced bitstream stylized as a “microbitstream.” The method and apparatus split FPGA configuration information into two separate configurations to reduce the initial configuration while applying encryption and authentication to the initial bitstream and leverage partial reconfiguration through a bootloader to load in secondary functionalities during or after run time of the initial configuration. Encryption and authentication are also applied to secure the bitstream from tampering, cloning, and malicious insertions. The present apparatus and methods achieve significant reductions in the total configuration time of an FPGA, which is particularly useful for time-sensitive systems, thus decreasing program development costs and time spent in the design process.Type: ApplicationFiled: July 24, 2024Publication date: April 3, 2025Applicant: The United States of America, as represented by the Secretary of the NavyInventors: Christopher Sozio, Grant Skipper, Adam Duncan

Patent number: 12260518Abstract: A method for using a single-pixel camera to reconstruct images of objects obscured by fog or other dynamic scattering media. A pseudo-random phase or intensity pattern is imposed on illumination beams directed at a target. The beam with the imposed pattern forms a pseudo random pattern on the target. Information regarding the pattern imposed on each pulse is entered into a data processor/controller. The illumination beams with the pseudo random patterns are reflected off the target, collected by receiving optics and a bucket detector and converted into electronic signals fed into the data processor/controller. The data processor/controller applies a high-pass filter to remove slower signal variations produced by dynamic changes in the scattering medium over time. The filtered bucket values are then used together with their corresponding speckle patterns to generate the images using any appropriate reconstruction algorithm such as CGI or CSI.Type: GrantFiled: March 10, 2022Date of Patent: March 25, 2025Assignee: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Mark Bashkansky, Samuel Park, John F.
