    摘要: A system for detecting light scattered from a tissue and for finding an IPL point for extracting oxygen saturation and pulse rate comprises: (a) at least one light source for illuminating a tissue, the at least one light source has a beam alignable to pass through the tissue; and (b) a plurality of photodetectors/cameras placed at multiple angles with respect to the tissue for collecting the light scattered from the tissue at multiple angles at the same time. The beam of the light source is centered either on a first axis parallel to the tissue and/or on a second axis with respect to the tissue, and the plurality of the photodetectors/cameras are either stationary or movable for conducting measurements at multiple angles for producing a first full scattering profile (FSP) and a second FSP applicable or finding the IPL point for extracting the oxygen saturation and the pulse rate.

    摘要: Processes for creating a two-dimensional-target structure are disclosed. An example process to create a two-dimensional-target structure may include the process of providing two-dimensional material grown on an initial substrate to create a two-dimensional-substrate structure; applying the two-dimensional-substrate structure to a target substrate via an adhesion promoter to create a lamination stack; applying a lamination process to the lamination stack; and then removing the initial substrate from the lamination stack, post-lamination, to create the two-dimensional-target structure. The two-dimensional-target structure may then be used in such rigid or flexible electronic devices and/or non-standard devices as the target substrate may be rigid or flexible and/or translucent in contrast to the initial substrate first used to grow the two-dimensional material.
