  • Publication number: 20250114052
    Abstract: An X-ray imaging system, such as a computed tomography (CT) computed tomography (CT) imaging system is provided for material decomposition calibration and intended for use with a calibration phantom. The X-ray imaging system comprises an X-ray source configured to emit X-rays and an X-ray detector arranged in the X-ray beam path configured to generate detector data. The calibration phantom is located in the X-ray beam path. The X-ray imaging system further comprises an X-ray beam limiting device including at least one calibration element in the X-ray beam path. The X-ray imaging system also comprises image processing circuitry configured to acquire projection data for a set of projections based on the detector data, and to determine pathlengths through at least one material of the at least one calibration element and at least one material of the calibration phantom, at least partly based on acquired projection data, for performing material decomposition calibration.

  • Patent number: 9628086
    Abstract: An antifuse apparatus can include a cantilever extending from a first electrode portion to terminate in a distal end. A second electrode portion can be spaced apart from the cantilever by an air gap. In response to a program voltage across the first and second electrode portions, the cantilever can be adapted to move from an unprogrammed condition, corresponding to an open circuit condition where the cantilever is spaced apart from the second electrode portion, to at least one permanent programmed condition, corresponding to a short circuit condition between the first and second electrode portions where the cantilever engages the second electrode portion.

  • Publication number: 20160047855
    Abstract: This disclosure relates generally to printed circuit board authentication, such as for protecting printed circuit boards against counterfeiting. The authentication can be implemented based on measurements from the PCB used to generate a unique signature for the PCB. The generated signature of the PCB can be evaluated to determine if the PCB is authentic or counterfeit.
