  • Publication number: 20240384198
    Abstract: Compositions and devices are provided that provide a persistent low-friction coating on a solid surface, by application of a mixture of a polyethylene glycol-containing surfactant and a vegetable to the surface. The coating thus generated does not require replenishing during use and persists through rinsing and multiple uses. Surprisingly, markedly reduced friction is found when the surfactant is provided at 3% w/v to 7% w/v in the composition. Such compositions and methods are suitable for application to both mixing and separation operations. Formulation of such compositions with food grade components permits use in food processing.

  • Patent number: 12144667
    Abstract: An apparatus and method for medical imaging uses a first and second contrast agent, the second agent targeted to a particular tissue type. First images are obtained using the first agent, and second images using the second agent using medical imaging systems. An image processing system is adapted to process the first and second medical images by fitting parameters of a pharmacokinetic model to the first medical images, identifying a nontargeted tissue type, scaling the fitted parameters to best match the nontargeted tissue in the second medical images, executing the pharmacokinetic model to prepare a correction image, and generating corrected medical images by subtracting the correction image from the second medical images.

  • Patent number: 12140774
    Abstract: An afocal sensor assembly detects a light beam with an aberrated wavefront. The afocal sensor assembly is configured to provide sorted four-dimensional (4D) light field information regarding the light beam, for example, via one or more plenoptic images. Based on the 4D light field information, a lossy reconstruction of an aberrated wavefront for one or more actuators of an adaptive optics (AO) device is performed. The AO device can be controlled based on the lossy reconstruction to correct the wavefront of the light beam. In some embodiments, the aberrated wavefront is due to passage of the light beam through atmospheric turbulence, and the lossy reconstruction and correction using the AO device is performed in less than 1.0 ms. The lossy reconstruction of the aberrated wavefront can have a phase accuracy in a range of ?/2 to ?/30.
