Abstract: An example computing system that maintains a playlist of media items for playback by one or more playback devices receives, from a first playback device, a request to play back the playlist and first operational data and also receives, from a second playback device, a request to play back the playlist and second operational data. The computing system provides the media items in the playlist to the first and second playback devices for substantially synchronous playback and, based on the first and second operational data, determines respective first and second advertisements. The computing system provides the first advertisement to the first playback device for playback during a given time slot designated for advertisements, and also provides the second advertisement to the second playback device for playback during the given time slot, such that the second playback device plays the second advertisement while the first playback device plays the first advertisement.

Abstract: An Auto Setup Program (“ASP”) may be implemented in the sound system of a vehicle to accomplish the goal of a dramatically improved audio quality achievable in any vehicle, regardless of the speaker components and head-unit utilized. The ASP performs automated time alignment measurements and equalizer processes using an external microphone. The ASP eliminates the need for expensive and time consuming professional tuning operations. The on-board ASP can be run multiple times as desired. For example, the ASP can be executed after changes to the system, such as upgrading speakers.

Abstract: An example computing device in a media playback system receives a first request to create a first zone scene including a first preconfigured grouping of zones including a first zone and a second zone, and based on the first request, causes creation and storage of the first zone scene. The computing device receives a second request to create a second zone scene including a second preconfigured grouping of zones including the first zone and a third zone, and based on the second request, causes creation and storage of the second zone scene. While displaying a representation of the first zone scene and a representation of the second zone scene, the computing devices receives a third request to invoke the first zone scene, and based on the third request, causes the first zone scene to be invoked such that the first zone and the second zone become configured for synchronous playback of media.

Abstract: A device and method for adjusting an output to an audio port based on a determined sensitivity is provided. The device comprises a processor, an audio port, and an electrical measurement device configured to measure electrical properties of an external device plugged into the audio port over a range of frequencies. Using the electrical measurement device, one or more electrical properties of the external device plugged into the audio port are measured at a plurality of frequencies. A sensitivity of the external device is determined using the one or more electrical properties of the external device measured using the electrical measurement device. An output to the audio port is adjusted based on the sensitivity.

Abstract: In one arrangement, a person's position in a movie auditorium is discerned by detection of audio signals from two or more speakers, and the person is then assigned a role or task in a game based on this discerned location. In another arrangement, a person's current position in a home listening environment is similarly discerned; this position information is used to control the balance of complementary audio channels of a home audio system, so that the audio “sweet spot” is located at the person's current position. A great number of other features and arrangements are also detailed.

Abstract: Techniques for controlling the volumes of multiple audio output devices using a collective (master) volume control and an individual volume control for each audio output device. In one set of embodiments, each individual volume control can be configured to indicate the current absolute volume level of its corresponding audio output device. When the master volume control is manually adjusted, the individual volume controls can be automatically adjusted in a manner proportional to the manual adjustment of the master volume control. In addition, when an individual volume control is manually adjusted to a setting or value that exceeds the master volume control, the master volume control can be automatically adjusted to be equal to, or greater than, the manually adjusted setting for the individual volume control. In this scenario, the other individual volume controls can remain unchanged.

The robot is supported to operate in a horizontal plane by an insulating pole. The robot is hung in a vertical plane to support operation by an insulating rope. The locating mechanism can grip a socket accurately, which can be indicated in place by a horizontally positioned lamp and a vertically positioned lamp. The clamping mechanism can clamp a W-pin for disassembling and assembling. The transmission mechanism can transmit the clamping mechanism to clamp, release, advance and retreat the clamp. Placement and clamping of the clamp can be indicated with a clamping position lamp and a limiting lamp. The live working robot can replace the insulator string without the need of power cut, is in simple structure, works reliably and accurately and is time and labor saving. The living working robot is used for maintenance of high voltage lines.

Abstract: Techniques for enhancing audio at a network-accessible computing platform and then providing the enhanced audio to a client device. By enhancing the audio remotely at the computing platform rather than locally at the client device, the client device need not include the infrastructure (e.g., hardware and software) required to perform these audio enhancements. Therefore, the client device may be manufactured at a lesser expense as compared to devices that perform the enhancements themselves. Instead, the client devices described herein simply receive the pre-enhanced audio and directly output this audio.
