Abstract: Methods and apparatus consistent with the invention provide the ability to organize, index, search, and present time series data based on searches. Time series data are sequences of time stamped records occurring in one or more usually continuous streams, representing some type of activity. In one embodiment, time series data is stored as discrete events time stamps. A search is received and relevant event information is retrieved based in whole or in part on the time stamp, a keyword indexing mechanism, or statistical indices calculated at the time of the search.

Abstract: A method of retail engagement includes receiving a worn article from a user in a retail establishment, where the worn article includes dirt or debris on an outer surface of the article. The method then includes robotically cleaning the worn article to at least partially remove the dirt or debris on the outer surface. The cleaning comprises contacting the shoe with a rotating brush, and at least one of the worn article or the rotating brush is robotically manipulated to cause the contacting. Finally, the outer surface of the article may be adorned with one or more adornments, where the one or more adornments are selected by the user.

Abstract: A sliding material including: a substrate, and a textured sliding layer overlying the substrate, where the sliding layer includes asperities including a plurality of apexes and nadirs, where 1) the sliding layer has a root mean square gradient of less than 0.064; 2) the sliding layer has an apex material portion of less than 10%; 3) the sliding layer has a nadir material portion of less than 75%, and where the textured sliding layer induces formation of a film when engaged in a rotational interface w/ another component.

Abstract: Systems and methods include providing a stator vane bushing for a variable stator vane assembly having a movable stator vane and a stator vane housing disposed annularly about the movable stator vane. The bushing includes a flange, a barrel extending from the flange, and a central aperture extending through the flange and the barrel and is disposed in the housing and annularly about the stator vane. The bushing is formed from a ceramic material having a coefficient of thermal expansion (CTE) lower than or equal to a CTE of one or more of a stator vane and a housing of the variable stator vane assembly.
