  • Patent number: 10353514
    Abstract: The present application is directed to dynamic input mode selection. In general, a system may sense a user's finger approaching a surface of a display (e.g., an imminent user touch input) and, depending on at least one trigger condition, may perform at least one output operation. For example, a first trigger condition may cause a display to enlarge at least a portion of a displayed image based on the imminent user touch input, a second trigger condition may cause the display to present a menu corresponding to an object in the enlarged portion, etc. This functionality may be implemented utilizing either an operating system (OS)-aware configuration or an OS-unaware configuration. In an OS-aware configuration, an intent-to-touch (ITT) module may utilize application program interfaces (APIs) in the OS to facilitate display zooming, menu presentation, coordinate translation, etc. In an OS-unaware configuration, the ITT module may facilitate these actions without OS assistance.

  • Patent number: 9552356
    Abstract: Techniques described enable creation of a single log containing information from both server-side and client-side logs. A logging service receives page requests and other data from a user operating a computing device. These page requests are then stored in a server-side log. The logging service also receives interactions made by the user on a displayed page. These interactions are then stored in a client-side log separate from the server-side log. The logging service then converts a format of the data in the client-side log and merges the client-side and server-side logs to form a single log. A service provider may then analyze this single log to track how this and other users navigated the pages associated with the page requests.

  • Patent number: 5599150
    Abstract: A hitch pin for maintaining a clevis pin in a bore including a continuous wire member formed to include a straight portion ending in a constant radius hinge portion. A parallel portion extends from the hinge portion to a constant radius barb portion. The termination of the barb portion is located on the side of the straight portion opposite the parallel portion and resiliently maintained there by properties of the hinge portion as accentuated by material properties of the wire itself. The hitch pin may be installed in a bore defined in a clevis pin by applying force to the hinge portion after inserting the leadin portion in the bore. During installation, the barb portion is resiliently deformed about the clevis pin and returns to a preinstalled position when the hitch pin installation has been completed. Any forces attempting to remove the hitch pin cause the barb portion to strike the clevis pin presenting a mechanical obstruction to removal.
