An example computing device in a first mode is configured for playback of given audio content. While in the first mode, the computing device displays a representation of one or more playback devices in a media playback system that are available to accept playback responsibility for the given audio content and receives user input indicating a selection of a given playback device. The computing device transmits an instruction for playback responsibility to be transferred to the given playback device such that i) an identifier of the given audio content and a playback position for the given audio content are provided to the given playback device and ii) the given playback device becomes configured for playback of the given audio content. The computing device transitions from the first mode to a second mode in which the computing device is configured to control the given playback device's playback of the given audio content.

Techniques described herein may involve modification of playback based on the proximity of a user to a playback device. An example technique involves a device determining that a listener is within a given proximity of a first playback device and based on determining that the listener is within the given proximity of the first playback device, causing the first playback device to begin playback of first media and causing a second playback device to modify playback of second media.

An example zone player is configured to play back a first media item identified in a remote playback queue provided by a computing system that is communicatively coupled to the zone player via at least a cloud-based network. The zone player is also configured to, while playing back the first media item, transmit a first indication that the zone player is ready for a next one or more media items identified in the remote playback queue and, after transmitting the first indication, (i) receive, from the computing system, data for retrieving at least a second media item identified in the remote playback queue from a cloud-based media service, and (ii) use the data for retrieving the second media item to retrieve the second media item from the cloud-based media service. The zone player is also configured to transition from playing back the first media item to playing back the second media item.

An amplifier selection device includes: a storage means for storing a database containing information pertaining to motor models, amplifier capacities and feature amounts; a means that obtain information of motor models necessary to configure a desired system; a means that calculate a number of necessary amplifiers; a means that select spindle amplifiers; a means that create a combination of servo amplifiers for each spindle amplifier; a means that extract information pertaining to the feature amounts by referring to the database; a means that determine a combination on a basis of the information pertaining to the feature amounts; a power source capacity calculation means that calculate capacities of a main power source and a control power source by referring to the database; and a display control means that display the combination of amplifiers along with the main power source and control power source capacities.

Example implementations may involve using a prompt to prevent inadvertent control or playback of audio content. When a mobile device receives input data indicating a command to play back audio content on a first playback device, the mobile device determines whether the mobile device is in proximity to the first playback device. If the mobile device determines that the mobile device within a given proximity to the first playback device, the mobile device transmits, via the network interface, one or more commands to instruct the first playback device to play back the audio content. However, if the mobile device determines that the mobile device outside the proximity, the mobile device displays a prompt indicating that the mobile device is the outside the given proximity to the first playback device and a selectable control that, when selected, transmits the one or more commands to play back the audio content.

Systems, methods, apparatus, and articles of manufacture to facilitate connection to a multimedia playback network are disclosed. An example method provides content to a local playback network. The example method includes identifying multimedia content from a content provider. The example method includes passing information regarding the multimedia content to a local playback system including one or more multimedia playback devices in response to a trigger. The example method includes facilitating play of the multimedia content via a local playback network associated with the local playback system.

A real-time hydraulic representation system may comprise a memory to store information on components of a hydraulic system. The real-time hydraulic representation system may receive a component data comprising a hydraulic component type, and upstream data and downstream data associated with the component data. The real-time hydraulic representation system may generate a node comprising the component data, the upstream data, and the downstream data. Additionally, the real-time hydraulic representation system may generate a diagram illustrating the node in relation to a plurality of other nodes based on the component data, the upstream data, and the downstream data.

A system and method for controlling media through a user interface integrated within a taskbar is described. This system and method enable a user to control media while a user interface of another application remains in perspective. Further, this system includes a taskbar media player, which can play media and enable a user to control the play of that media from within a taskbar.

A digital downloading jukebox system including a mechanism for delivering custom services to a recognized user is provided. For example, information specific to a recognized user may be stored and optionally may include a recognized user avatar representative of the recognized user. The user avatar may be an image, video, and/or animation, which may be displayed on and/or played through the jukebox. The user avatar may be associated with transactions associated with the user. For example, an avatar may be displayed when a playlist of the recognized user is played, when a message is sent, etc. In other examples, the avatar may introduce instances of media by playing an audio and/or video message, and the avatar may sing, dance, etc. while an instance of media is playing.
