  • Publication number: 20250130206
    Abstract: An ultrasound inspection probe for a machine tool that includes a probe body and elongate member that extends from probe body and has datum surface for contacting object to be inspected. Probe also includes an ultrasound transducer and coupling assembly for acoustically coupling ultrasound transducer to object to be inspected. Ultrasound coupling assembly includes carrier shell containing ultrasound coupling element having transducer-contacting face coupled to ultrasound transducer and object-contacting face for acoustically coupling to object to be inspected. Bearing mechanism movably attaches ultrasound transducer and coupling assembly to elongate member allowing movement between extended position wherein object-contacting face of ultrasound coupling element extends beyond datum surface and measurement position wherein object-contacting face of ultrasound coupling element is substantially flush with datum surface.

  • Publication number: 20250130203
    Abstract: An ultrasound inspection probe is described for use with a coordinate positioning apparatus, such as a machine tool. The probe includes a probe body for mounting to a coordinate positioning apparatus and an elongate member extending from the probe body. The elongate member includes an ultrasound transducer assembly and a datum surface at its distal end. A movable joint connects a proximal end of the elongate member to the probe body and this movable joint is configured to permit both lateral and rotational movement of the proximal end of the elongate member relative to the probe body such that the elongate member can rotate about its distal end to allow the datum surface to angularly align with a surface of an object to be inspected. In this manner, the datum surface aligns with the surface of the object being inspected to optimise acoustic coupling.

  • Patent number: 11149851
    Abstract: A wear resistant coated piston ring for an engine is provided. The piston ring includes a coating disposed on a ring body. The coating includes initially includes alternating first and second layers, wherein the first layers include trivalent chromium, and the second layers include nickel and phosphorous. The first layers are applied by depositing a trivalent chromium electrolyte, specifically Cr3+ electrolyte. The second layers are applied by electroless deposition. The coating is left in the as-is condition and is not heat treated before being disposed on a piston and then in an engine. The coating is naturally exposed to heat while the engine is running, and this heat causes the chromium, nickel, and phosphorous of the layers to diffuse and form a surface layer on a compound layer. The surface layer includes trivalent chromium, and the compound layer includes a ternary compound of chromium, nickel, and phosphorous.

  • Patent number: 10600232
    Abstract: A texture level of detail (LOD) approximation may be performed utilizing ray differentials and a G-buffer. For example, a scene to be rendered is identified, and a G-buffer of the scene is rendered. Additionally, ray tracing is started for the scene, and during the ray tracing, a ray differential is created by accessing the G-buffer. Further, the created ray differential is appended to a current ray, and the created ray differential is traced.

  • Patent number: 10460504
    Abstract: A method, computer readable medium, and system are disclosed for performing a texture level-of-detail approximation. The method includes the steps of identifying a scene to be rendered, projecting a ray passing through a pixel of a screen space, resulting in a first hit point at a geometry element within the scene, determining a footprint angle of the pixel, determining a curvature measure for the geometry element at the first hit point within the scene, computing a texture level of detail (LOD) approximation for a component of the scene, utilizing the footprint angle of the pixel and the curvature measure for the geometry element, and performing, utilizing a hardware processor, one or more rendering operations for the scene, utilizing the texture LOD approximation.

  • Patent number: 9262583
    Abstract: Apparatus, methods, and other embodiments associated with evaluating global deformations and local deformations in a prostate are described. One example apparatus includes logics that evaluate global and local deformations in a prostate and register a pre-External Beam Radiation Treatment (EBRT) three dimensional (3D) magnetic resonance (MR) image with a post-EBRT 3D MR image. An image acquisition logic acquires a pre-EBRT image and a post EBRT image of an organ, item, or volume. An image texture information logic extracts image texture information from the pre-EBRT and post-EBRT images. A finite element model (FEM) transformation logic constructs a FEM of the volume imaged in the pre-EBRT image, deforms the FEM, deforms the pre-EBRT image as a function of the deformed FEM, and maximizes the image texture similarity between the deformed pre-EBRT image and the post-EBRT image. A registration logic registers the pre-EBRT image with the post-EBRT image based on the transformation.
