  • Patent number: 10390160
    Abstract: An apparatus and method for verifying voice messages generated by notification devices in an emergency address system includes one or more verification devices and a validation module, which can be part of a control panel or a connected services system. The verification devices can be mobile computing devices or permanently installed devices associated with each notification device in the emergency address system. The verification devices include microphones, network interfaces, and controllers executing speech to text conversion processes. During testing, the notification devices play voice messages and the verification devices detect the messages, convert the messages to text and send the text-converted messages to the validation module, which validates the text-converted messages against the intended messages for each notification device and confirms that the messages were played in the correct locations.

  • Patent number: 10284981
    Abstract: Examples are provided for establishing a bonded zone comprising a first playback device comprising a respective first wireless radio and a second playback device comprising a second respective wireless radio. The first and second playback devices may establish a bonded zone comprising at least the first and second playback device. While in the established bonded zone, the first playback device may determine that the first playback device is in the established bonded zone and that the first playback device is not currently playing audio in synchrony with the second playback device. Responsive to determining that the first playback device is not playing audio in synchrony, the first playback device may disable communicating via the first wireless radio of the first playback device and send a message to the second playback device to disable communicating via the first wireless radio of the second playback device.

  • Patent number: 10275809
    Abstract: Systems and methods for delivering digital content to user who have pre-selected the digital content before they arrive at a device for distributing the digital content are described. The systems contain a storage device where the digital content is stored, a device for distributing the digital content to a user, a receiving device for receiving the digital content that has been distributed, and means for communicating with the user who is not located at the distribution device. The communication means allows the user to browse and/or purchase the digital content prior to arriving at the distribution device. As well, by purchasing the content before arrival, if the digital content is not located at the distribution device, it can be transferred from the storage device to the distribution device before the arrival of the user. Other embodiments are described.

    Abstract: Practical speaker connection is identified using a device having a sound channel of a 5.1 channel or 7.1 channel, and a device is provided that can easily reproduce the optimum multiple channels. Actual speaker arrangement can be identified by, for example, measuring the impedance of a terminal at the side of an audio amplifier. If incorrect connection is found, a warning is issued. This information is transmitted to a signal source with an EDID and a signal with the optimum a number of sound channel is sent. The EDID is also used for the connection with a display unit and the speaker connection with which the display unit is provided uniquely. For example, a sound through the 7.1 channel is easily reproduced using the speaker of the display unit in the channel of the front speaker.

  • Patent number: 9510116
    Abstract: A high definition distributed sound system has a master control hub with multiple serially linkable zones each capable of handling multiple serial arrays of powered speakers and a Cat5 cable. Each zone has an audio input, an internal master level controller and multiple powered-speaker outputs. Each of the serial arrays of powered speakers are connected to a corresponding powered-speaker output by the Cat5 cable. All of the zones can be used and controlled independently of the others or any number of them can be serially linked and controlled by their preceding zones. Additional master control hubs can be serially linked in a single system. The system interconnections can be done with Cat5 cable using RJ45 connectors. A low idle current power amplifier circuit offers extremely low levels of quiescent current, allowing a large number of speakers to be connected in one system.

  • Patent number: 8879748
    Abstract: A wireless audio client device such as a headset worn by a user allows the user to talk with multiple other devices using different communication protocols. In one approach, the wireless audio client device is a slave device which pairs with multiple master devices such as a game console and cell phone. The wireless audio client device uses a common set of peripherals such as a speaker, microphone, RF antenna, battery, status lights and control buttons. Processing circuitry is provided in one or more chips, to handle the different communication protocols. The wireless audio client device can automatically interrupt a game chat to allow the user to accept an incoming phone call, or can prompt the user to accept the call. Or, the wireless audio client device can play audio from the cell phone while the game chat continues.
