Abstract: A medical device performs a method for determining a cardiac event by obtaining a signal comprising cardiac cycle length information in a patient and determining cardiac cycle lengths during an established time interval. Noise is detected during the time interval and a cardiac cycle length corresponding to a time of the detected noise is rejected. Cycle length differences are determined from the cycle lengths not rejected during the time interval. The cardiac event is determined in response to the cycle length differences.

Abstract: Techniques and configurations for an apparatus are provided for creating and managing meetings using gestures. Movements of a user's hand in a three-dimensional space are detected. The hand movements in the three-dimensional space are interpreted to identify a gesture intended by the user to set up or manage a meeting among a plurality of persons. An electronic command is generated from the detected gesture to set up or manage the meeting.

Abstract: Playback of multimedia data associated with a recorded conference session is simplified, particularly for a person who participated in the conference session from a mobile device. At a recording server that is in communication with a plurality of endpoints in a conference session, multimedia received from the plurality of endpoints participating in the conference session is recorded. The recording server obtains geographical location information for at least one mobile endpoint participating in the conference session as the at least one mobile endpoint moves. The recording server temporally correlates the geographical location information for the at least one endpoint with recorded multimedia data for the conference session. The recording server stores data tags for the geographical location information for the at least one mobile endpoint in association with the recorded multimedia data for subsequent use in indexing to map data to retrieve a portion of the recorded multimedia data for playback.

Abstract: An end station for a videoconference/multimedia conference is disclosed, where the end station requests, receives and displays multiple video streams. Call control messages request video streams with specified video policies. A static policy specifies a constant source video stream, e.g., a participant. A dynamic policy dynamically maps various source streams to a requested stream and shows, for example, the current speaker, or a round robin of participants. A network access device, e.g., a media switch or a video composition system, mediates between the multi-stream end station and the core conference system. Multi-stream endpoints need not handle the complexity of directly receiving video according to a potentially wide variety of call control protocols, formats, and bit-rates. Multi-stream endpoints decentralize compositing video streams, which increases functional flexibility and reduces the need for centralized equipment.

Abstract: In an example embodiment, there is disclosed herein an automatic speech recognition (ASR) system that employs speaker clustering (or speaker type) for transcribing audio. A large corpus of audio with corresponding transcripts is analyzed to determine a plurality of speaker types (e.g., dialects). The ASR system is trained for each speaker type. Upon encountering a new user, the ASR system attempts to map the user to a speaker type. After the new user is mapped to a speaker type, the ASR employs the speaker type for transcribing audio from the new user.

Abstract: A conference adapter. In an illustrative embodiment, the conference adapter implements a method for interfacing one or more conference endpoints with one or more conference servers. The method includes registering an endpoint and a conference server to determine endpoint registration information associated with the endpoint and to determine conference-server registration information associated with the conference server. Next, the method includes receiving a connection from the endpoint and a connection from the conference server. Subsequently, the conference adapter establishes communications between the endpoint and the conference server as initiated by the endpoint and based on the endpoint registration information and the conference-server registration information. In a more specific embodiment, the method further includes receiving plural connections from conference servers of disparate types, and then selectively switching communications between the endpoint and a first conference server to communications between the endpoint and a second conference server. The method further includes selectively switching endpoints for a given conference session.
