  • Publication number: 20240118413
    Abstract: The present disclosure provides a method for surface wear inspection using millimeter wave radar. The system initially receives a plurality of uncompressed raw Synthetic Aperture Radar (SAR) images. Further, a plurality of reconstructed SAR images are generated based on the plurality of uncompressed raw SAR images using a variable focusing based Range Doppler Algorithm (RDA). Further, a master image and a slave image are selected from the reconstructed SAR images and corresponding anchor points are assigned. Further a plurality of fine level and coarse level shift coordinates are computed based on the corresponding anchor points. Further, a net shift value is computed based on the plurality of fine level and coarse level shift coordinates. The master and the slave images are aligned based on the net shift value and the interferogram is generated. The interferogram is further analyzed to profile the corresponding deformation pertaining to the surface under test.

  • Patent number: 11541826
    Abstract: A bracket for a display assembly includes a body that has a first edge and a second edge that define a first surface and a second surface of the body. An elongated retention feature is coupled to the first edge of the body and defines an elongated slot proximate to the first surface of the body. A plurality of retention clips are coupled to the second edge of the body. Each of the plurality of retention clips define a slot proximate to the first surface of the body. At least one housing is coupled to the second surface of the body and defines locking apertures. At least one cap is selectively coupled to the at least one housing. The at least one cap defines locking features selectively disposed within the locking apertures that are defined by the at least one housing.
