  • Patent number: 12634575
    Abstract: A media application receives, from a server, an identification of a first composition type from a set of compositions to apply to an initial image captured with a user device. Responsive to one or more people being detected in the initial image, the media application generates a modified image, where the one or more people are removed from the initial image to obtain the modified image. The media application scores at least one candidate position within the modified image based on corresponding composition rules for the first composition type. The media application provides a graphical guide on a viewfinder of the user device to guide a user to capture a final image, wherein the graphical guide indicates a recommended position for the one or more people in the final image.

  • Patent number: 12585182
    Abstract: Various examples described herein include a correction for a layer-to-layer or substrate-to-substrate overlay alignment based upon feedback from critical-dimension (CD) measurements of locations of various features that are to be formed on subsequently formed layers of a substrate with regard to locations of similar features on previously formed layers. The layer-to-layer or substrate-to-substrate overlay-alignment feedback can be enhanced by determining positions of multiple ones of the features on each of the formed layers with respect to the first layer in the stack. Further, the layer-to-layer or substrate-to-substrate overlay-alignment feedback can be enhanced by determining positions of multiple ones of the features on each of the formed layers with respect to the previously formed layer. Overlay-alignment errors may be sent back to a photolithographic exposure tool. An accumulated overlay error can be flagged. Other techniques and methods are also disclosed.

  • Publication number: 20250355368
    Abstract: Various examples herein describe an apparatus and related method to track and correct alignment errors of features used on a substrate. For example, in various embodiments, the disclosed subject-matter is a method for measuring x-coordinates and y-coordinates of a number of features (such as vias) on a layer on the substrate for each of the layers formed on the substrate that are to underlie a subsequently formed layer; compare the x-coordinates and the y-coordinates on the layer to respective locations of a production file used to determine a planned location of the features for each of the respective layers; prepare offset data based on the comparison for each of the respective layers; and enter the offset data into a lithographic tool database to minimize or correct the alignment errors for each of the respective layers. Other systems, apparatuses, and methods are also disclosed.

  • Patent number: 12322778
    Abstract: The present disclosure relates to an energy module having a plurality of energy generating cells, and at least one cooling plate having opposing surfaces. The cooling plate is disposed between an adjacent pair of the energy generating cells such that the opposing surfaces of the cooling plate are in contact with surfaces of the adjacent pair of energy generating cells. The cooling plate has at least one coolant flow channel configured to receive a coolant flow therethrough to limit propagation of heat from one to the other of either one of the adjacent pair of energy generating cells when either one of the adjacent pair of energy generating cells fails.
