Abstract: Systems, devices, and methods that utilize assistive listening systems, central control of endpoint devices, and a screen are described herein. Some environments, such as a classroom, may include legacy assistive listening systems. Systems may be configured to coordinate assistive listening functions between the legacy assistive listening system and other audio output devices. In such cases, the audio output devices and/or a stationary device may be used in conjunction with a legacy assistive listening system. The audio output devices and/or the stationary device may be configured to communicate one or more settings for one or more control parameters of the audio output devices. The stationary device may provide centralized control of at least some control parameters of the audio output devices. The stationary device may include a screen or display to output visual data in addition to audio data.

Abstract: Systems, devices, and methods for assistive listening that uses sound waves for devices pairing is described herein. An assistive listening system may use sound waves to pair mobile devices acting as assistive listening devices with stationary devices. To establish a communication link (e.g., pair the two devices), a mobile device may exchange a plurality of signals over a plurality of sound waves with a stationary device. The plurality of sound waves may operate in a set of frequencies above a frequency range detectable by a human ear (e.g., above 20 kHz). After the pairing procedure over the sound waves is complete, the assistive listening system may use electromagnetic waves to pair the mobile devices with the stationary devices over a wireless access technology, such as Digital Enhanced Cordless Telecommunications (DECT).

Abstract: Systems, devices, and techniques are described herein to establish and/or maintain communication links between devices using signals communicated over high-frequency sound waves. To establish a communication link (e.g., pair the two devices), a mobile device may exchange a plurality of signals over a plurality of sound waves with a stationary device. The plurality of sound waves may operate in a set of frequencies above a frequency range detectable by a human ear (e.g., above 20 kHz). The communication link may be established using a radio frequency access technology, such as DECT, after the pairing procedure over the sound waves is complete. Using sound waves to pair devices and maintain device pairings may increase the locality of device pairings because sound waves cannot penetrate walls or structures as easily as electromagnetic waves.

Abstract: Systems, devices, and methods for using sounds waves to locate a mobile device in a wireless communication network are described herein. Some sound waves may not be capable of penetrating or passing through many objects such as structures. Consequently, the number of signal paths that a sound wave may take to reach one or more receivers may be reduced, as compared to electromagnetic waves. A wireless communication system may be configured to use sound waves to more accurately determine a location of the mobile device transmitting a signal in the wireless communication system. The plurality of sound waves may operate in a set of frequencies above a frequency range detectable by a human ear (e.g., above 20 kHz). The wireless communication system may be configured to identify the location of a device that is transmitting alert message or panic messages seeking assistance.

Abstract: A watersports paddle includes an elongated handle body having a first material, a biased member having a second material more flexible than the first material such that the biased member is more flexible than the elongated handle body, and a paddle blade coupled to the biased member opposite the elongated handle body. The biased member deforms when a force is applied to the biased member with the elongated handle body by pulling the paddle blade through water and reforms when the force is not applied to the biased member by the elongated handle body to store and release energy during use of the watersports paddle. The biased member may be a substantially planar leaf spring or a bowed leaf spring.

Abstract: The present disclosure generally relates to systems, devices, or methods for providing low-latency communication between content sources and output devices. An integration device may be configured to integrate input data streams from a plurality of sources, including legacy systems (e.g., intercom systems or telephone systems), and output a combined data stream to the relevant output devices. Rooms increasingly include a variety of multimedia devices such as televisions, speakers, projectors, individual computers, etc. In some cases, a room may have redundant output devices that are specialized for a particular system. For example, a room may have a speaker for a television, a speaker for an intercom system, a speaker for an audio system, or various combinations thereof. By managing multiple input data streams and multiple output data streams, the integration device may be configured to reduce the need for redundant hardware.

Abstract: A power and stabilizing apparatus for rolling or sliding-based recreational activities is disclosed. The apparatus may include a shafted body coupled to a biased member. The biased member may be a bowed biased member or any other biased member configured to store and release energy during use of the apparatus. The apparatus may also include a shoe coupled to the biased member opposite the body, the shoe having a traction element coupled thereto. The body may be a shafted telescoping body configured to lock in an extended position and lock in a retracted position. The body may be coupled to the bowed biased member with a coupling member having a first leg coupled to the body and a second leg coupled to the bowed biased member.
