摘要： A method and system for determining a relative location of a device on a network is provided. In this system and method, a list of landmark nodes provided on the network is received. Then, a value which is a time, a latency and/or a distance from the device to each of the landmark nodes is determined. Each of the determined values corresponding to the respective node of the landmark nodes is transmitted to a central arrangement to provide the relative location of the device with respect to the landmark nodes.

摘要： A system includes the ability to establish a communication session between stations using protocol capabilities of an external transcoder. The stations may establish a communication session by exchanging protocol capabilities which include a protocol capability of at least one remotely located transcoder. The communication session may then be established using appropriate signalling protocol, including peer-to-peer signalling protocols.

摘要： Marking a keyframe of a media stream in a communication system involves one or more entry media switches in communication with one or more endpoints. An entry media switch receives a media stream from an endpoint, where the media stream comprises a sequence of packets with a keyframe. The keyframe is detected and marked with a keyframe indicator. The keyframe indicator is operable to notify a downstream device of the keyframe. An output media stream is outputted.

摘要： A method of communicating information between a first program and a second program over a network is described. The method includes relaying the information between the first program and a first communications program over a first network connection, relaying the information between the first communications program and a second communications program over a second network connection and relaying the information between the second communications program and the second program over a third network connection. Further, the first communications program creates the second network connection to the second communications program through a first firewall program, which prevents access to the first program initiated by the second program. Thus, the second network connection is initiated by the first communications program. The first communications program can be, for example, a protocol daemon and the second communications program can be, for example, a relay program. The first firewall program can also be configured to prevent access to the first program initiated by the second communications program.

摘要： A medical device performs a method to classify a cardiac rhythm. Differences between cycle lengths in a first heart chamber are determined during an established time interval. Evidence of ectopy associated with irregular coupling intervals is detected from the signal during the established time interval. A rhythm classification output corresponding to a second heart chamber at the expiration of the established time interval is provided in response to the consecutive cycle length differences and the evidence of ectopy associated with irregular coupling intervals.

摘要： 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.

摘要： The disclosure describes techniques for quantifying the autonomic nervous system (ANS) health of a patient with thoracic impedance measurements. Thoracic impedance may be measured utilizing cardiac electrodes and an implantable medical device housing or other electrodes located on or within the patient. Since greater variability in thoracic impedance may indicate better health of the ANS, monitoring impedance changes in a patient may be used to quantify autonomic tone of the ANS, and ultimately, overall patient health. In some examples, thoracic impedance may be measured in response to a change in patient posture for acute monitoring or at predetermined times over several days, weeks, or months for more chronic monitoring of the patient. An implantable medical device may independently analyze the impedance measurements and transmit an alert to the patient or clinician when impedance changes indicate a change in patient health.

摘要翻译： 本公开描述了用于量化具有胸部阻抗测量的患者的自主神经系统（ANS）健康的技术。 可以使用心电极和位于患者内部或内部的可植入医疗装置外壳或其它电极来测量胸腔阻抗。 由于胸部阻抗变化较大可能表明ANS的健康状况良好，所以监测患者的阻抗变化可用于量化ANS的自主音调，并最终对整体患者的健康状况进行量化。 在一些示例中，可以响应于用于急性监测的患者姿势的变化或在几天，几周或几个月的预定时间来测量胸部阻抗以进行更长期的患者监测。 当阻抗变化表示患者健康状况发生变化时，植入式医疗设备可以独立地分析阻抗测量结果并向患者或临床医生发送警报。
