  • Publication number: 20180327899
    Abstract: An article comprises a body having a coating. The coating comprises a Y-O-F coating or other yttrium-based oxy-fluoride coating generated either by performing a fluorination process on a yttrium-based oxide coating or an oxidation process on a yttrium-based fluorine coating.

  • Publication number: 20180330923
    Abstract: A method of applying a multi-layer plasma resistant coating on an article comprises performing plating or ALD to form a conformal first plasma resistant layer on an article, wherein the conformal first plasma resistant layer is formed on a surface of the article and on walls of high aspect ratio features in the article. The conformal first plasma resistant coating has a porosity of approximately 0% and a thickness of approximately 200 nm to approximately 1 micron. One of electron beam ion assisted deposition (EB-IAD), plasma enhanced chemical vapor deposition (PECVD), aerosol deposition or plasma spraying is then performed to form a second plasma resistant layer that covers the conformal first plasma resistant layer at a region of the surface but not at the walls of the high aspect ratio features.

  • Patent number: 10006884
    Abstract: Determining a Curie temperature (Tc) distribution of a sample comprising magnetic material involves subjecting the sample to an electromagnetic field, heating the sample over a range of temperatures, generating a signal representative of a parameter of the sample that changes as a function of changing sample temperature while the sample is subjected to the electromagnetic field, and determining the Tc distribution of the sample using the generated signal and a multiplicity of predetermined parameters of the sample.

  • Patent number: 9685183
    Abstract: An apparatus includes a substrate and a magnetic layer coupled to the substrate. The magnetic layer includes an alloy that has magnetic hardness that is a function of the degree of chemical ordering of the alloy. The degree of chemical ordering of the alloy in a first portion of the magnetic layer is greater than the degree of chemical ordering of the alloy in a second portion of the magnetic layer, and the first portion of the magnetic layer is closer to the substrate than the second portion of the magnetic layer.

  • Patent number: 9489051
    Abstract: A device and method to facilitate display navigation by touch-less gesture are described. The device includes two or more ambient light sensors arranged at respective surface locations of the device, each of the two or more ambient light sensors measuring light intensity at the respective surface location. The device also includes a processor to detect a gesture as a detected gesture performed by an object in touch-less communication with the device and output a signal corresponding with the detected gesture, and a navigation gesture library to store two or more gestures and corresponding two or more signals, wherein the processor accesses the navigation gesture library when the device is not executing an application with an associated application gesture library.
