Abstract: Aspects of the present invention relate to methods for characterizing a multi-layered tire tread. In one example, a method comprises providing a first rubber composition having a first refractive index and providing a second rubber composition having a second refractive index. The method further comprises determining a difference between the first refractive index and the second refractive index and comparing the difference to a threshold refractive index. In addition, the method comprises adding a refractive index modifier to the first rubber composition and/or second rubber composition in case the comparison provides that the difference is lower than the threshold refractive index, so that the difference is greater than, or equal to, the threshold refractive index.

The system further comprises tag readers for wirelessly receiving and reading electromagnetic signals. In particular, each of the wheels comprises one of the tag readers for receiving electromagnetic signals sent by one of the tags mounted in a wheel well. Furthermore, the invention is directed to a vehicle comprising a wheel monitoring system, wherein each tag of a plurality of tags comprises unique information identifying one or more of the tag and a mounting position of the tag. Moreover, the invention is directed to a method of locating mounting positions of wheels.

Abstract: This invention relates to tire tread wear monitoring. A sacrificial magnet portion is arranged in a tread of the tire so that it undergoes wear along with the tread and generates a useful magnetic field signal indicative of remaining tread thickness. With a magnetic field sensor arranged on or in the tire, an overall magnetic field signal is measured, which includes the useful magnetic field signal, and a superimposed interfering magnetic field signal generated by magnetizable material contained in the tire. A non-sacrificial magnet portion is used to saturate the magnetizable material at least locally so as to make the interfering magnetic field signal sensed by the magnetic field sensor substantially independent of the useful magnetic field signal sensed by the magnetic field sensor. Further aspects of the invention relate to tires, e.g., vehicle tires, featuring a tire tread wear monitoring system.

The controller is configured to operate the coextruder based on the response of the multi-layer tire tread extrudate to the THz electromagnetic radiation.

Abstract: The invention provides a method and an apparatus for measuring a thickness of each layer of a tire tread or a tire component, wherein the tire tread or tire component has conductive and non-conductive layers. One or more sensors are used, which emit radiation beams or pulses that travel through one or more of the layers. The radiation beams or pulses are reflected from the surfaces and interfaces of the layers and received by a receiving device of the one or more sensors. The reflected radiation beams or pulses are used to determine a thickness of each tread layer.

Abstract: A method for generating a user interface within a graphics application for a set of materials, such that each material includes a material definition and is capable of being applied to a geometry in a graphics scene when performing a rendering operation. A GUI generation engine obtains configuration information associated with an environment for a computer system and determines that a first set of materials is associated with the configuration information. The GUI generation selects the first set of materials to be displayed in a graphical user interface, and the graphical user interface is displaying to an end-user. Advantageously, embodiments of the invention provide for a technique for exposing only those materials, user interface objects, editable material parameters, user interface elements, vocabulary, rendering engines, and/or rendering engine implementations that are relevant to the user of a particular rendering application.

Abstract: One embodiment of the invention sets forth a mechanism for displaying lighting values associated with a 3-D graphics model by superimposing an overlay grid with lighting values on the 3-D graphics model. A software rendering engine computes lighting values for each frame that includes the 3-D graphics model, where each frame may have different lighting settings. An overlay grid with lighting values may be superimposed on an area defined by a light meter on the 3-D graphics model. The lighting values on the overlay grid are associated with the light meter and may vary frame-over-frame. In another embodiment, a JPEG image with a superimposed overlay grid with per-pixel lighting values covering a 3-D graphics model is generated for each frame that includes the 3-D graphics model. These JPEG images may be displayed on the screen and stored to an external memory.

Abstract: A method for generating a library of materials that can be applied to geometry in a graphics scene when performing rendering operations. The method includes generating a class file that includes material parameters representing rendering characteristics of a material class and generating a library root file that includes a reference to the class file. The method further includes generating a rendering implementation file for translating values of the material parameters into a format recognized by a particular rendering engine and generating a user interface file that includes at least one user interface configured to allow a user to modify the values of the material parameters. The method also includes linking the class file to the library root file, and linking the rendering implementation file and the user interface file to the class file. Advantageously, the library can be organized and updated more effectively when compared to prior art techniques.
