  • Publication number: 20200151372
    Abstract: In an approach for providing simulation results of an interaction between a transducer head and a magnetic medium, a computer identifies a first raster scan of a sample via a scanning probe microscope. The computer generates a topography image based on the first raster scan of the sample. The computer identifies one or more reference features within the created topography image. The computer calculates an average height based on the one or more reference features. The computer determines a lift distance associated with a probe of the scanning probe microscope. The computer defines a uniform plane based on the calculated average height and the determined lift distance. The computer performs a second raster scan of the sample based on the defined uniform plane. The computer generates a fly-height image based on the second raster scan. The computer provides simulation results based at least in part on the second raster scan.

  • Publication number: 20190362750
    Abstract: A method for measuring a distance between features of a sample, according to one embodiment, includes moving a precision stage having the sample thereon for positioning a first feature of the sample in a field of view of an imaging device. The imaging device is instructed to generate a first image of the first feature of the sample. The sample is moved a defined distance using the precision stage. The imaging device is instructed to generate a second image of a second feature of the sample at the defined distance. The first image and the second image are used to determine an actual distance between the first feature and the second feature. A product, according to one embodiment, includes a thin film structure having a plurality of elements, and at least two features dedicated for enabling measurement therebetween. Each feature is positioned at a known position relative to a respective one of the elements.

  • Publication number: 20190217186
    Abstract: An electronic game subscribes to events—such as a physical gesture or appearance of the user, certain spoken user commands, or the like—identified by a game mediation infrastructure. The game mediation infrastructure receives user input data received from the user's client device, analyzes the data, and determines whether one of the events subscribed to by the electronic game has occurred. If so, the game mediation infrastructure notifies the electronic game of the occurrence of the event, and the electronic game alters the state of the game accordingly. The electronic game may additionally and/or alternatively use an API of the game mediation infrastructure to cause alteration of a user interface of a game mediator component in which the electronic game is displayed, based on actions taking place within the game.

  • Publication number: 20190217205
    Abstract: An environment includes one or more clients, a game mediator server, and a game server connected by a network. The clients include a game mediator and a game. The game server executes game playing sessions of the games. The game mediator server and the game mediators form a game mediation infrastructure to mediate game playing sessions. For example, the game mediation infrastructure creates “lobbies” for game playing sessions and enables clients connected to lobbies to communicate with one another. The games receive interactions at the client and communicate with the game server to impact execution of game playing sessions. The game mediator server sends deep links to clients, e.g., to initiate game installation, or to start the game at a particular portion of the game. The game mediation infrastructure may also enrich gameplay by customizing gameplay and/or the lobby, e.g. based on events that occur during execution of the game playing session, or locations of the clients.
