Abstract: Example techniques involve selection of playback devices within a media playback system for outputting a media stream based on user input. An example implementation involves a controller causing a plurality of first representations of at least some of a plurality of playback devices to be displayed on a first portion of a display. The controller causes a plurality of second representations of at least some of one or more groups playback devices to be displayed on a second portion of the display, each group having at least two associated playback devices of the plurality of playback devices. The controller receives an input indicative of a particular group of the one or more groups and adjusts a selected status of the particular group. The controller also determines which playback devices are associated with the particular group, and adjusts a selected status of the playback devices that associated with the particular group.

Abstract: An example computing device establishes a first network connection to a playback device that supports a first communication protocol for sending audio content for playback to the playback device, and detects user input associated with a modification to the playback. While the computing device and the playback device are connected to a common data network that supports a second communication protocol, the computing device transmits, via the common data network using the second communication protocol, a command to modify media playback based on the user input. While the computing device or playback device are not connected to the common data network that supports the second communication protocol, the computing device (i) establishes a second network connection to the playback device that supports a third communication protocol, and (ii) transmits, via the second network connection using the third communication protocol, a command to modify media playback based on the user input.

Abstract: An example computing device is configured to use a first communication protocol to connect to a local network. After connecting to the local network, the computing device uses the first communication protocol to receive first information identifying a first playback device connected to the local network. The computing device also uses a second communication protocol different from the first communication protocol to connect to a second playback device that is not connected to the local network. Further, the computing device uses a third communication protocol different from the first and second communication protocols to receive second information identifying the second playback device. The computing device displays (i) a first representation of the first playback device based on the first information identifying the first playback device and (ii) a second representation of the second playback device based on the second information identifying the second playback device.

Abstract: Tar sand and Gilsonite are preferably crushed together so that the Gilsonite overcomes the stickiness of the tar sand and the tar sand alleviates Gilsonite dust, the relative proportions and the character of Gilsonite being such as to produce an additive product for an asphalt, usually refinery asphalt, and a resulting modified asphaltic cement for paving purposes to simulate Trinidad Lake Asphalt. One embodiment of the additive composition of the invention results in an asphaltic cement that outperforms that produced by use of Trinidad Lake Asphalt as the additive, while a second embodiment of the additive composition of the invention contains additional tar-sand-extracted bitumen and the resulting asphaltic cement more closely matches the performance of that containing Trinidad Lake Asphalt as the additive. The invention includes a system for extracting bitumen from tar sand and in one form provides for adding Gilsonite to the extracted liquid bitumen so it will effectively solidify when cooled.

Abstract: A composition useful in copying and printing is described. In one embodiment, the composition comprises a purified fraction of uintaite and a thermoplastic polymer. Preferably, the composition comprises a maltene-enriched fraction of uintaite derived by solvent extraction, a thermoplastic polymer and a colorant. In another embodiment, the present invention is an electrophotographic method comprising the steps of generating a latent electrostatic image; developing said latent image with a toner comprising a purified fraction of uintaite; and fixing said toner. The present invention is also a printing ink emulsion comprising a maltene-enriched fraction of uintaite.

Abstract: A water-based drilling mud additive comprising a pre-blended combination of about 2 parts of high softening point uintaite, about 1 part of a lower softening point uintaite, about 1 part of causticized lignite, and a strongly lipophilic, non-ionic surfactant is disclosed. This composition decreases shale sloughing and borehole instability during drilling of wells.
