Abstract: A videoconferencing device at an endpoint determines whether a person is a real person standing in front of a display device or if the person is instead an image rendered by a display device. In the first instance the real person will be included in a video feed for transmission to a remote endpoint. In the second instance, images of the display device on which the person is rendered will not be included in the video feed.

The first speaker is further disposed such that an audio output of the first speaker falls within a null of the second microphone.

Abstract: A method for determining camera framing in a teleconferencing system comprises a process loop which includes acquiring an audio-visual frame from a captured a video data frame; detecting objects and extracting image features of the objects within the video data frame, ingesting the audio-visual frame into a context-based audio-visual map in an intelligent manner, and selecting targets from within the map for inclusion in an audio-video stream for transmission to a remote endpoint.

Abstract: A method for interrupt based pairing for wireless audio devices includes determining a colocation of a wireless audio device with a subsequent wireless audio device with one or more sensors. An interrupt is generated in response to determining the colocation. A pairing mode of the wireless audio device is enabled in response to the interrupt. The wireless audio device is paired with the subsequent wireless audio device.

The earbud includes a stem having a proximal end and a distal end, a speaker disposed inside the stem at the distal end, and a sleeve disposed inside the stem. The earpiece also includes a housing connected to the proximal end of the stem. The housing contains firmware configured to communicate electronically with the speaker and to communicate wirelessly with an external device. The housing also contains curved partial sleeves. Each of the curved partial sleeves is adjacent an inner surface of a wall of the housing.

Abstract: A method for secure call endpoint pairing is disclosed. The method includes starting, at a call endpoint, a pairing procedure with a wireless headset. Also, the method includes receiving a headset identifier from the wireless headset. Further, the method includes sending the headset identifier in a request to a headset registry server, and receiving, from the headset registry server, a response to the request. Additionally, the method includes terminating the pairing procedure based on the response from the headset registry server.

Abstract: Methods and apparatuses for heart rate detection are described. In one example, a headphones apparatus and method includes emitting a first light in a first light direction directed at a left ear location from a left ear light emitter, and detecting a detected first light at a left ear light detector following interaction of the first light with a left ear tissue. The method includes emitting a second light in a second light direction directed at a right ear location from a right ear light emitter, the right ear location different from the left ear location. The method further includes detecting a detected second light at a right ear light detector following interaction of the second light with a right ear tissue, and estimating a heart rate from the detected first light and the detected second light.

Abstract: A method may include receiving a source video frame captured using a wide angle lens, deriving a characteristic of a target video frame from the source video frame, generating a transitional video frame using the source video frame and the target video frame, and transmitting the transitional video frame to an endpoint.

Abstract: Headphones include an earbud, including a knob-shaped body, an earbud tip extending from the knob-shaped body and configured to enter an ear canal of a listener, a harness strap interface disposed on the knob-shaped body and configured to removably accommodate a detachable harness strap.

Abstract: Methods and apparatuses for multiple radio frequency band operation are described. In one example, a first device is operated in a first radio frequency band. A connection request is received at the first device from a second device utilizing the first radio frequency band. The connection request is processed to designate whether the connection request is a priority services request type or a non-priority services request type. Responsive to designating the connection request as the non-priority services request type, a non-priority services communications channel is established utilizing a second radio frequency band. Responsive to designating the connection request as a priority services request type, it is determined whether a priority services channel is available or not available in the first radio frequency band.

Abstract: A method is disclosed for performing extension mobility via a headset connection. The method includes receiving a headset identifier from a headset. Also, the method includes, in response to receiving the headset identifier, sending the headset identifier to a device management server. Further, the method includes receiving a call control user identifier from the device management server, and sending, to a call control server, the call control user identifier. Still yet, the method includes receiving, from the call control server, a configuration profile associated with the call control user identifier. One or more settings of a desk phone are configured using the configuration profile.

Abstract: A mobile phone stations is disclosed. In general, in one aspect, the mobile phone station connects to a smartphone for sending and receiving data therebetween. Further, the mobile phone station includes a dial pad for placing outgoing calls via the smartphone and answering incoming calls received at the smartphone. Also, the mobile phone station includes a charging mechanism for charging the smartphone. In use during an active call at the smartphone, the mobile phone station allows a user to seamlessly switch between two or more of a handset, a speakerphone, and a headset without requiring any user interaction with the smartphone.

Abstract: The present disclosure concerns a multi-cable positioning device and a headset with multi-cable positioning device. The device comprises at least a fastening portion for removable attachment to clothing, and a cable management portion. The cable management portion comprises at least a first cable receptacle for a first cable, and a second cable receptacle for a second cable, wherein the cable receptacles are adapted for rotational and translational locking of the cables to increase comfort and stability.

Abstract: Scene changes that are done pleasingly and without user input or control. Based on the number of speakers and changes in speakers, either to a different individual or movement by the same speaker, based on the locations of the speakers and based on the overlap of the current and intended scenes, a decision is made whether to perform a smooth transition or do a cut. It has been determined that the decision on cut versus smooth transition is preferably based on the location of the center of the intended new scene versus the boundaries of the current scene, a cut used if the center is outside the boundaries and a smooth transition if inside. If a smooth transition, an easing function, such as ease in ease out, is performed to change the scene. A preferred value for the smooth transition is to perform the transition over 80 frames.

Abstract: A method is provided for encoding multiple microphone signals into a composite source-separable audio (SSA) signal, conducive for transmission over a voice network. The embodiments enable the processing of source separation of the target voice signal from its ambient sound to be performed at any point in the voice communication network, including the internet cloud. A multiplicity of processing is possible over the SSA signal, based on the intended voice application. The level of processing is adapted with the availability of the processing power at the chosen processing node in the network in one embodiment. An apparatus for separating out the target source voice from its ambient sound is also provided. The apparatus includes a directed source separation (DSS) unit, which processes the two virtual microphone signals in the SSA representation, to generate a new SSA signal including the enhanced target voice and the enhanced ambient noise.
