摘要： 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.

摘要： A method and apparatus for allocating call resources during a conference call are disclosed. A conference call between a plurality of clients is conducted on a first call resource. The clients communicate media streams to the first call resource for mixing. A media gateway identifies a second call resource to conduct the conference call and mix the media streams, and transfers the conference call from the first call resource to the second call resource without suspending communication of a plurality of mixed media streams received by the clients.

摘要： In one embodiment, a method for enhanced call pickup includes accessing data indicating a current status of each of one or more users in a call pickup group (CPG) with respect to an incoming phone call to a phone number corresponding to the CPG and communicating the data to one or more endpoints of one or more users in the CPG for display to one or more users in the CPG. A display of the data to a first user in the CPG facilitates the first user determining a current status of each of one or more second users in the CPG to facilitate a decision by the first user regarding whether to pick up the incoming phone call.

摘要： A method for executing a video conference is provided that includes receiving one or more audio streams associated with a video conference from one or more end points and determining an active speaker associated with one of the end points. Audio information associated with the active speaker may be received at one or more media switches. One or more video streams may be suppressed except for a selected video stream associated with the active speaker, the selected video stream propagating to one or more of the media switches during the video conference. The selected video stream may be replicated such that it may be communicated to one or more of the end points associated with a selected one of the media switches.

摘要： Techniques for transmitting diagnostic information stored in an implantable medical device (IMD) based on patient hospitalization are described. For example, the IMD may transmit higher resolution diagnostic information to a clinician and/or an external device during a hospitalization period to aid the clinician in evaluating heart failure treatment and when discharge is proper. This higher resolution diagnostic information may include one or more patient metrics automatically generated and transmitted by the IMD at least once every two hours. During a post-hospitalization period, the IMD may transmit lower resolution diagnostic information to a clinician that indicates a risk level of re-hospitalization. The lower resolution diagnostic information may include the risk level and/or patient metrics once a day, for example. In this manner, the IMD transmitted diagnostic information may be tailored to the specific heart failure monitoring needed by the patient.

摘要： Techniques for estimating a cardiac chamber or vascular pressure based upon impedance are described. A device or system may measure an impedance between at least two electrodes implanted within or proximate to a cardiovascular system. The device or system may estimate a pressure of an element of the cardiovascular system based on a relationship between impedance and volume of the element, and based on a empirical relationship between the volume and the pressure. The device or system may also estimate the dimension of the element based on the impedance-volume relationship, or other characteristics based on the impedance. Because the impedance measurements may be obtained, in some examples, by using electrodes and leads implanted within the cardiovascular system and coupled to an implantable medical device, a practical estimation of a cardiovascular pressure can be obtained on a chronic basis without requiring the use other invasive sensors, such as micronanometer transducers.

摘要： System and method for identifying a prospective clinical therapy for a prospective patient. The patient has a medical device, performed with a medical apparatus. The system has a historical database and an analyzer. The historical database incorporates information relating to a multiplicity of patients, each of the multiplicity of patients having a medical device and each of the multiplicity of patients having undergone a clinical therapy, the information including, for each of the multiplicity of patients, device characteristics of the medical device and an assessment of efficacy of clinical therapy. The analyzer correlates device characteristics of the prospective patient with the device characteristics and the assessment of efficacy of clinical therapy of the multiplicity of patients using the historical database to identify a prospective clinical therapy for the prospective patient associated with the device characteristics in the historical database having a relatively greater efficacy than the clinical therapy.
