Abstract: A system may include a controller coupled to a user interface. A user may provide user commands specifying mapping relationships between one or more audio inputs and one or more audio zones via the user interface. The controller may be configured to determine individual audio inputs to be outputted to individual audio zones based on a priority policy. The system may further include audio streaming applications coupled to the controller. The controller may launch the audio streaming applications to the user interface for interaction with the user. The audio streaming applications may provide audio streams to be outputted at the individual audio zones. The system may further include a streaming interface coupled to the controller and the audio streaming applications and configured to receive the audio streams. The streaming interface may be further configured to transmit the audio streams to output devices of the individual audio zones.

Abstract: According to an aspect of an embodiment, a method may include receiving, at an embedded computing device of a multi-zone audio amplifier system, audio inputs from audio sources. The method may further include mapping the audio inputs to an zone for the audio inputs to be available for the zone, in which the zone represents a location having a speaker configured for playback of sound. A particular audio input may be selected from the audio inputs for transmission to the zone, where such selection may be based on a priority policy. The embedded computing device may transmit the particular audio input to the zone using an amplifier associated with the zone. The method may further include causing the speaker to play the particular audio input.

The embedded computing device may cause a user interface to be displayed on a mobile device via a mobile application. The user interface may show a list of zones and a list of audio inputs. The embedded computing device may obtain a user input via the user interface. The user input may indicate relationships between the audio inputs and the zones. The zones may represent physical locations. Each of the physical locations may include an audio output device configured to play sound.

The amplifiers may obtain a portion of the audio inputs based on the relationships. The amplifiers may also provide the portion of the audio inputs to the audio output device.

Abstract: According to an aspect of an embodiment, a multi-zone audio amplifier may include an audio manager, a data bus, and multiple amplifiers coupled to the data bus. The audio manager may obtain audio inputs representative of sound to be played at an audio output device, from an audio source via a network. The multiple amplifiers may provide audio outputs representative of the sound to multiple zones, each zone corresponding to one or more different audio output device for playback of the sound. The multiple amplifiers may receive the audio inputs from the audio manager via the data bus.

Abstract: Devices that couple to high voltage transmission lines obtain power themselves using the body capacitance of an element of the devices. The devices generate a comparatively lower voltage from the current flowing between the high voltage line and the element of the device that generates the body capacitance. The devices can be used to operate sensors that monitor the transmission lines or parameters of the power distribution system, such as current, line temperature, vibration, and the like. The devices can also be used as indicators, such as aircraft warning lights, information signs, etc. In addition, the devices can operate as RF transmission/reception or repeater devices, radar devices, mesh networking nodes, video/audio surveillance, sound emitting devices for scaring animals, drones that traverse the power line, etc. Because the devices operate in response to line voltage rather than current, the devices are reliable even in low current conditions.
