  • Patent number: 12276017
    Abstract: Multi-layer metal or pseudometallic materials having engineered anisotropy are disclosed. The multi-layer materials having defined engineered grain orientations in each layer of the multi-layer material and bond layers between adjacent layers orthogonal to the grain orientations. This configuration distributes applied stress across the plurality of layers in the multi-layer metal material and around a neutral axis of the multi-layer metal material and increases the overall mechanical properties of the disclosed multi-layer metal material relative to conventional wrought metal materials of the same or similar chemical constitution. The microstructure of each layer, group of layers, or across multiple layers may be tailored to the intended application of a device made from the material. Individual layers may be tuned for property variations, such as gradients, or to adjust the bond layer characteristics.

  • Patent number: 11624635
    Abstract: The present invention provides a method for realizing high stability of micro-nano optical fiber sagnac loop output by means of filter mode control, and belongs to the field of photoelectric detection technologies. In the present invention, the optical filter is combined with the micro-nano optical fiber Sagnac interference structure so as to control the Sagnac in-loop working mode by use of the mode selection characteristics of the filter. In this way, the interference mode is suppressed to better concentrate energy on the working mode, thereby improving the spectrum output uniformity and stability of the Sagnac loop. Further, the reflection and transmission modes of the optical filter do not participate in interference spectrum output and thus the performance of the system will not be affected. By designing and changing the parameters of the optical filter, the output characteristics of the interferometer can be dynamically controlled.

  • Patent number: 11530958
    Abstract: An intelligent optical fiber tactile sounding system and a method thereof, and belongs to the field of intelligent optical fiber sensing. The system includes a flexible optical fiber tactile sensing array, a photoelectric detection system, an intelligent pressure analysis software and an acoustic emission system; a small-scale distributed tactile sensing array is constructed by embedding a fiber-core mismatched optical fiber interferometric sensor into a flexible substrate material and performing sensing region division for an asymmetrical structure with an optical fiber structure as a delimiting line; a tactile sensor transmits tactile signals to the photoelectric detection system in the form of optical signals, the photoelectric detection system inputs these pressure signals into the intelligent pressure analysis software to determine a region and a size of a tactile source, and then sends an instruction to the acoustic emission system to enable the acoustic emission system to emit different sounds.

  • Patent number: 6380096
    Abstract: An integrated in situ oxide etch process particularly useful for a counterbore dual-damascene structure over copper having in one inter-layer dielectric level a lower nitride stop layer, a lower oxide dielectric, a lower nitride stop layer, an upper oxide dielectric layer, and an anti-reflective coating (ARC). The process is divided into a counterbore etch and a trench etch with photolithography for each, and each step is preferably performed in a high-density plasma reactor having an inductively coupled plasma source primarily generating the plasma and a capacitively coupled pedestal supporting the wafer and producing the bias power. The counterbore etch preferably includes at least four substeps of opening the ARC, etching through the upper oxide and nitride layers, selectively etching the lower oxide layer but stopping on the lower nitride layer, and a post-etch treatment for removing residue.
