Abstract: Disclosed is a secure telephone call management system for authenticating users of a telephone system in an institutional facility. Authentication of the users is accomplished by using a personal identification number, preferably in conjunction with speaker independent voice recognition and speaker dependent voice identification. When a user first enters the system, the user speaks his or her name which is used as a sample voice print. During each subsequent use of the system, the user is required to speak his or her name. Voice identification software is used to verify that the provided speech matches the sample voice print. The secure system includes accounting software to limit access based on funds in a user's account or other related limitations. Management software implements widespread or local changes to the system and can modify or set any number of user account parameters.

Abstract: Example implementations may relate to creation and control of channels. In particular, a computing device may receive a first channel-addition request indicating content from a first audio-provider service and may responsively send to a server an instruction to establish a first channel that provides access to content from the first audio-provider service via an application-program account. With this arrangement, a subsequent second channel-addition request may then similarly lead to establishment of a second channel that provides access to content from the second audio-provider service via the application-program account. After channel-additions, the device may determine a first selection of the added first channel and may responsively cause content from the first audio-provider service to be output by an audio output device.

Abstract: A video calling service provides a mobile device user is provided the capability to transition from a voice call to a video call within a calling session in a voice over long term evolution (VoLTE). The example video calling service offers a seamless transition of a voice call to a video call in a simplified and efficient process. In an example, a graphical user interface is provided that allows a user to select controls to provide real-time stream of video of a live scene via a rear facing camera to another user during a video call. Other examples describe the merger of individual voice calls into a merged call with the individual calls grouped as a conference call. The examples provide simplified use of a mobile device to transition voice calls to a video call in a cellular carrier's mobile network.

Abstract: In one embodiment, a pre-correcting engine generates a pre-corrected signal that may be used to mitigate air path distortions in sounds generated by loudspeaker systems that include loudspeakers coupled to waveguides. In operation, the pre-correcting engine virtually propagates a target signal in a reverse direction from the output of the waveguide to the output of a driver. Notably, the pre-correcting engine implements a propagation distortion compensation model that, when applied to the target signal, corrects for the effects of air path distortions on the target signal. The pre-correcting engine then transmits the pre-corrected signal to the driver. As the driver drives the waveguide based on the pre-corrected signal, effects of the pre-corrected distortions negate effects of air path distortions and the loudspeaker system generates high-fidelity sounds.

Abstract: A computer-implemented online conferencing transactional platform system comprising an interaction module, a video-conferencing module, and a storage device may allow multiple participants in a video-conference to access, co-browse, collaboratively edit, and sign a transactional document. An interaction module fetches an image of a transactional document and a field identifier for an interactive transactional document element to be filled out from a remotely-connected secure signature API, and displays the image of the document, along with the interactive transactional document element on a webpage interface to a moderator and a signer end user in a video-conference. The interaction module receives a filled-out transactional document in an I-frame from the secure signature API, allowing the signer end user to sign the transactional document using a secure embedded signature process.

Abstract: The invention is directed to recording, transmitting, and displaying a three-dimensional image of a face of a user in a video stream. Reflected light from a curved or geometrically shaped screen is employed to provide multiple perspective views of the user's face that are transformed into the image, which is communicated to remotely located other users. A head mounted projection display system is employed to capture the reflective light. The system includes a frame, that when worn by a user, wraps around and grips the user's head. Also, at least two separate image capture modules are included on the frame and generally positioned relatively adjacent to the left and right eyes of a user when the system is worn. Each module includes one or more sensor components, such as cameras, that are arranged to detect at least reflected non-visible light from a screen positioned in front of the user.

Abstract: A headset includes a microphone that detects an acoustic signal, and converts the acoustic signal into a microphone signal, an audio processor that receives the microphone signal, and a twisted pair conductor element coupling the microphone and the audio processor.

Abstract: An electronic device may be configured to identify a load coupled to the device. The device may measure direct current (DC) and/or alternating current (AC) characteristics of the load to identify the load. The device may then take action based on the identification of the load. For example, a specific transducer may be identified as coupled to the electronic device and an appropriate equalization curve applied to an audio output of the device. The measurement of characteristics of the load may include controlling a reference generator according to a search algorithm, such as a step ramp or binary search, to identify the load. An analog-to-digital converter (ADC) may operate through the search algorithm to provide feedback to digital circuitry regarding how to proceed through the search algorithm to identify the load.

The first adjusted video content can be provided to the first recipient communication device via the video conference communication session. Non-adjusted video content can be provided according to the video conference policy to the second recipient communication device via the video conference communication session. Other embodiments are disclosed.
