Abstract: Systems and methods are described for searching media files using a set-top box (STB), a television receiver, digital video recorder (DVR), placeshifting device or other media device, or any type of network host that communicates with a media device of any sort. Search criteria is received from a user, and the search criteria is identified in listings of media programming available from one or more sources. In some implementations, a combined search result can be provided that identifies instances of the search criteria found in program guide listings, files stored on a digital video recorder (DVR), available on-demand content, or any other sources as desired. Some implementations may prioritize search results using information about files stored on a DVR, user preferences, or any other information as desired.

Abstract: A dynamic testing system for sealing devices includes a shaft that is reciprocated in a bore through a body. The shaft includes a first seal assembly and a second seal assembly disposed a distance apart on the shaft. When the shaft is inserted into the bore, the first seal assembly and the second seal assembly form a fluid-tight seal between the external surface of the shaft and the internal surface of the bore—this forms a fluid-tight cavity between the seal assemblies. Sealing devices in each of the first seal assembly and the second seal assembly experience chemical attack and mechanical wear. One or more axial force measurement sensors measure the force applied by a prime mover to reciprocate the shaft within the bore. Data acquisition circuitry collects the force information and generates a graphical output that plots friction force against reciprocating cycle count.

Abstract: An online system associated with a venue provides an application to client devices that allows a user to select an additional user from information accessible to a client device and to identify a meeting point within the venue for the user and the additional user to meet. The application identifies the additional user to an online system, which determines whether the additional user also uses the online system and is within a threshold distance of the venue. If the additional user is a user of the online system and is within the threshold distance of the venue, the online system transmits a request to travel to the meeting point to a client device associated with the additional user. The online system also provides directions to the user's client device and to the additional user's client device for the user and the additional user, respectively, to travel to the meeting point.
