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.

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.

An amplifier selection device includes: a storage that stores a database containing motor models and information pertaining to amplifier capacities and feature amounts; a means that obtains motor model information; a means that calculates a number of amplifiers; a means that selects spindle amplifiers; a means that creates a combination of servo amplifiers and spindle amplifiers; a means that extracts information pertaining to the feature amounts; a means that determines a combination on the basis of the information pertaining to the feature amounts; a power source capacity calculation means that calculates capacities of a main power source and a control power source; a means that calculates a total power consumed by motors; and a display control means that displays the combination of amplifiers and time series data of the total value of the power consumed by the motors along with the main power source and control power source capacities.

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.

Some embodiments of the disclosed systems and methods include displaying a graphical user interface comprising a first section and a second section, wherein the first section includes a first media icon corresponding to a first media item, and wherein the second section includes a first zone icon corresponding to a first zone comprising a first set of one or more playback devices; and in response to detecting a drag of the first media icon to the first zone icon, instructing at least one playback device in the first set of one or more playback devices to play the first media item corresponding to the first media icon.

A network device is configured to perform functions including (i) operating in a first playback-control mode including retrieving, via a first network interface, first media in a playback queue and streaming, via a second network interface to a headphone, the first media (ii) while streaming the first media to the headphone, displaying a representation of one or more playback devices in a media playback system, (iii) receiving input indicating a selection of a given playback device, (iv) based on the input, causing the given playback device to obtain data indicating the second media in the playback queue, use the obtained data to retrieve the second media, and play back the retrieved second media, and (v) after receiving the input, stopping streaming the retrieved first media and transitioning from operating in the first playback-control mode to operating in a second playback-control mode to control the given playback device's playback of the second media.

A first network device is configured to (i) receive, using a first communication protocol, first media content from a second network device, (ii) transmit, using a second communication protocol, the first media content to a third network device, (iii) cause the third network device to play back the first media content, (iv) receive second media content from a fourth network device, (v) receive, via a microphone, microphone data, (vi) while transmitting the first media content to the third network device and causing the third network device to play back the first media content, play back the second media content via an audio transducer, and (vii) while transmitting the first media content to the third network device and causing the third network device to play back the first media content, transmit, to the fourth network device, audio content corresponding to the received microphone data.

Some embodiments of the disclosed systems and methods for managing zones of a multi zone media playback system include displaying a plurality of zone icons in a first zone group display region, receiving a first drag and drop input that selects the second zone icon and drags the second zone icon from inside the first zone group display region to outside the first zone group display region, and after the first drag and drop input, (i) causing one or more zone players identified by the second zone icon to be disassociated with the first zone group, (ii) displaying the second zone icon outside the first zone group display region; and (iii) displaying a second status icon representative of a second playback status of the one or more zone players identified by the second zone icon.

A multiple recording device management system including an intermediate multiple recording device managing apparatus, a vehicle recording device mounted in a police vehicle and synced to the managing apparatus, and a personal recording device carried by a police officer and wirelessly synced to the managing apparatus. The managing apparatus is operable to detect when the vehicle recording device, personal recording device, or any other synced device in range has begun recording and to transmit a communication signal to any synced recording device in range indicating that the recording device should begin recording and to further transmit a time stamp to synced recording devices for corroborating recorded data.
