  • Publication number: 20260108723
    Abstract: An injectable wire structure electrode can assimilate with surrounding tissues after injection, inducing in-growth of blood vessels, collagen and other tissue. Assimilation secures the electrode to the tissue without sutures and prevents relative motion which can lead to inflammation and scarring. Associated methods of manufacturing and injection are disclosed, as well as systems including a dermal multiplexer for power delivery.

  • Publication number: 20260054056
    Abstract: A system for stimulating a tissue target in a body with an injectable electrode, either fully or partially implanted, may employ a protection device to prevent over-voltage or over-current from an external pulse generator (EPG) to the injectable electrode. Current is supplied from the EPG transcutaneously to the fully implanted injectable electrode and percutaneously to the partially implanted injectable electrode by various electrical connectors.

  • Patent number: 11282186
    Abstract: An aspect of the invention includes reading a scale in image data representing an image of physical characteristics and resizing at least a portion of the image data to align with target image data representing a target image based at least in part on the scale to form resized image data representing one or more resized images. Noise reduction is applied to the resized image data to produce test image data representing one or more test images. A best fit analysis is performed on the test image data with respect to the target image data. Test image data having the best fit are stored with training image data representing classification training images indicative of one or more recognized features. An anomaly in unclassified image data representing an unclassified image is identified based at least in part on an anomaly detector as trained using the classification training images.

  • Patent number: 11195969
    Abstract: A method of forming a metal silicide nanowire network that includes multiple metal silicide nanowires fused together in a disorderly arrangement on a substrate. The metal silicide nanowire network can be formed by applying a solution that contains silicon nanowires onto the substrate, forming a metal layer on the silicon nanowires, and performing a silicidation anneal such that the metal silicide nanowires are fused together in a disorderly arrangement, forming a mesh. After the silicidation anneal is performed, any unreacted silicon or metal can be selectively removed.

  • Patent number: 11056610
    Abstract: A method of forming a metal silicide nanowire network that includes multiple metal silicide nanowires fused together in an orderly arrangement on a substrate. The metal silicide nanowire network can be formed by printing a first set of multiple parallel silicon nanowires on the substrate and printing a second set of multiple parallel silicon nanowires over the first set of multiple parallel silicon nanowires such that said first set is perpendicular to said second set. A metal layer can be formed on the silicon nanowires. A silicidation anneal process is performed such that metal silicide nanowires are formed and fused together in an orderly arrangement, forming a grid network. After the silicidation anneal is performed, any unreacted silicon or metal can be selectively removed.

  • Patent number: RE50174
    Abstract: A semiconductor structure is provided that includes a semiconductor fin portion having an end wall and extending upward from a substrate. A gate structure straddles a portion of the semiconductor fin portion. A first set of gate spacers is located on opposing sidewall surfaces of the gate structure; and a second set of gate spacers is located on sidewalls of the first set of gate spacers. One gate spacer of the second set of gate spacers has a lower portion that directly contacts the end wall of the semiconductor fin portion.
