| 20090196213 | SYSTEM, DEVICE AND METHOD FOR CONTROLLING A BEARER CHANGE - A system and a device for controlling bearer change are provided. The system includes a bearer change notifying entity and a bearer change control entity. The bearer change notifying entity is adapted to acquire information that a bearer needs to be changed, and send a bearer change notice to the bearer change control entity. The bearer change control entity is adapted to determine and control conversion from a multicast bearer mode to a unicast bearer mode or conversion from the unicast bearer mode to the multicast bearer mode according to the received bearer change notice. Further, a method for controlling bearer change is also provided. The system, the device, and the method are capable of sensing changes in multicast capability and user will and establishing the unicast/multicast bearer mode for data transmission | 08-06-2009 |
| 20110019620 | METHOD, SYSTEM, AND APPARATUS FOR SWITCHING STREAMING SERVICE - A method, a system, and an apparatus for switching a streaming service are disclosed herein. The method for switching a streaming service is applied in IP Multimedia Subsystem (IMS) architecture and includes: receiving a switching request that carries an identifier of requested media; and using a before-switching media channel to send switched media content to User Equipment (UE). The streaming service switching method disclosed herein uses the fast switching capability of the real-time streams in the IMS architecture to switch the streaming service, and uses the before-switching media channel to transmit the switched media content in the IMS architecture, thus improving the switching speed, the user experience, and the network capability of controlling the switching. | 01-27-2011 |
| 20110023071 | Method, System, and Apparatus for Creating Content-on-Demand Service - A method, a system, and an apparatus for creating a Content-on-Demand (CoD) service are disclosed herein. The method includes receiving a Session Initiation Protocol (SIP) service request sent by a User Equipment (UE); converting the SIP service request into a Real-Time Streaming Protocol (RTSP) service request, and sending the RTSP service request to a server; receiving an RTSP service response sent by the server; and converting the RTSP service response into a SIP service response, and sending the SIP service response to the UE to create the CoD service between the UE and the server. | 01-27-2011 |
| 20110060900 | METHOD, SYSTEM, CORRESPONDING DEVICE, AND COMMUNICATION TERMINAL FOR PROVIDING MBMS SERVICE - A method, a system, a security device, a service control device, and a communication terminal for providing a Multimedia Broadcast/Multicast Service (MBMS) service are provided. The method includes the following steps: A service control module in an IP Multimedia Subsystem (IMS) system carries out service authorization according to a service authorization request, and obtains an authorization-passed result. The service control module sends the authorization-passed result to a security module. The security module obtains the authorization-passed result and then sends a service decryption code of the MBMS service to UEs. In the present invention, a controlling capacity of an IMS and a bearer capacity of an MBMS are multiplexed based on an IMS system and an MBMS system to achieve IPTV services, so as to achieve the uniform authorization and uniform network management. The binding of the IPTV service with other services based on the IMS can be achieved by using the IMS, and personalized services can be provided to UEs. | 03-10-2011 |

| 20080262559 | Method and apparatus for adjusting the sensing threshold of a cardiac rhythm management device - A method and apparatus for automatically adjusting the sensing threshold of cardiac rhythm management devices. The invention is particularly suited for implementation in devices such as implantable cardiac pacemakers and implantable cardioverter/defibrillators. A method and apparatus are provided in which a noise level and signal level for a sensing channel are determined for each cardiac cycle with the sensing threshold of the channel being adjusted in accordance therewith. | 10-23-2008 |
| 20090187228 | AUTOCAPTURE PACING/SENSING CONFIGURATION - A cardiac electrical stimulation system that enhances the ability of the system to automatically detect whether an electrical stimulus results in heart capture or contraction. The cardiac electrical stimulation system may be utilized, for example, as a cardiac pacer or as a cardioverter defibrillator. The cardiac electrical stimulation system includes an electrical stimulation circuit that attenuates polarization voltages or “afterpotential” which develop at the heart tissue/electrode interface following the delivery of a stimulus to the heart tissue, which thereby allows the stimulation electrodes to be utilized to sense an evoked response to the electrical stimulus. The cardiac electrical stimulation system utilizes the stimulation electrodes to sense an evoked response, thereby eliminating the necessity for an indifferent electrode to sense an evoked response. The present invention allows accurate detection of an evoked response of the heart, to thereby determine whether each electrical stimulus results in capture. | 07-23-2009 |
| 20090306737 | Atrial Capture Verification - Methods and systems for classifying cardiac responses to pacing stimulation and/or preventing retrograde cardiac conduction are described. Following delivery of a pacing pulse to an atrium of the patient's heart during a cardiac cycle, the system senses in the atrium for a retrograde P-wave. The system classifies the atrial response to the pacing pulse based on detection of the retrograde P-wave. The system may also sense for an atrial evoked response and utilize the atrial evoked response in classifying the cardiac pacing response. | 12-10-2009 |
| 20110022109 | WIRELESS ECG IN IMPLANTABLE DEVICES - An implantable medical device such as an implantable pacemaker or implantable cardioverter/defibrillator includes a programmable sensing circuit providing for sensing of a signal approximating a surface electrocardiogram (ECG) through implanted electrodes. With various electrode configurations, signals approximating various standard surface ECG signals are acquired without the need for attaching electrodes with cables onto the skin. The various electrode configurations include, but are not limited to, various combinations of intracardiac pacing electrodes, portions of the implantable medical device contacting tissue, and electrodes incorporated onto the surface of the implantable medical device. | 01-27-2011 |
| 20110230926 | MAXIMUM PACING RATE LIMITER SYSTEM - A maximum pacing rate limiter for use in adaptive rate pacing in conjunction with a cardiac rhythm management system for a heart. The maximum pacing rate limiter may function to measure an interval, termed the ERT interval, between a paced ventricular evoked response and a T-wave. The maximum pacing rate limiter may further function to maintain the ERT interval at less than a certain percentage of the total cardiac cycle. In one disclosed embodiment, a maximum pacing rate limiter calculates an ERT rate based on the detected paced ventricular evoked response and the T-wave, and the pacing rate limiter module further communicates the minimum of the ERT rate and an adaptive-rate sensor indicated rate to a pacemaker. | 09-22-2011 |
