Abstract: A system and method for reserving conference resources for a multipoint conference includes receiving a request for a multipoint conference reservation and a list of participants. Communication paths for a plurality of the participants may be predicted. A multipoint control unit resource requirement may be estimated. A first multipoint control unit may be selected to host the multipoint conference. The availability of the multipoint control unit resource requirement at approximately a scheduled start time of the multipoint conference may be determined. A second multipoint control unit may be selected to host the multipoint conference, if the first multipoint control unit does not have the multipoint control unit resource requirement available at the scheduled start time and for the duration of the conference.

Abstract: Methods and apparatus are provided for discriminating high rate polymorphic QRS complexes from high rate monomorphic QRS complexes to increase the specificity of detection of polymorphic VT and VF employing wavelet transform signal processing of the QRS complexes are disclosed. Wavelet transforms are applied to the sampled amplitude values of a sequence of QRS complexes to develop wavelet transform coefficient (WTC) data sets. At least selected ones of the WTC data sets are processed and comparisons are made to determine a wavelet match score. A determination is made as a function of the wavelet match scores of the series of successive QRS complexes that characterizes the most recent QRS complex as more or less likely to signify polymorphic VT or VF.

Abstract: A multi-layer method for detecting atrial arrhythmias using ventricular cycle length information that includes performing a base layer algorithm for detecting the onset and offset of an atrial tachyarrhythmia. The multi-layer method further includes one or more higher layer algorithms executed in response to a base layer detection to confirm or reject the base layer detection. The base layer is designed to operate with high sensitivity to atrial fibrillation and/or organized atrial tachycardia and the higher layer is designed to operate with high sensitivity and high specificity to atrial fibrillation and/or organized atrial tachycardia.

Abstract: Disclosed are methods and apparatus for methods and apparatus for automatically contacting a service center for one or more particular products, as well as contacting other types of entities with respect to any type of item. In a first embodiment, each item includes a radio frequency identification (RFID) of the particular products that is used to automatically contact a service center or the like. In a second embodiment, the RFID of the particular product is automatically sent to the service center or the like. In the first embodiment, the RFID of each product contains contact information, such as a 1-800 telephone number, a URL address, or email address, for a particular service center or the like. In one implementation, an RFID reader is coupled with a communication device, such as a telephone or computer device, and the user uses the RFID reader to scan an RFID of a particular item (e.g., a malfunctioning product). The relevant service center or the like is then contacted based on the RFID scan. For example, the user is connected to an agent at the relevant service center via a telephone or computer network. In the second embodiment, when a service center (or the like) needs RFID tag data for a particular item, a user may select a “send” option (e.g., on the communication device or reader) to have such RFID tag data automatically transmitted to the service center or the like.
