Appl. No.:

09/535882

Inventors:

Antonis A. Armoundas - Cambridge MA
Andrew B. Feldman - Newport RI
Derin A. Sherman - Lincoln MA
Richard J. Cohen - Chestnut Hill MA

Assignee:

Massachusetts Institute of Technology - Cambridge MA

International Classification:

A61B 504

US Classification:

600373, 600515

Abstract:

This invention involves method and apparatus for guiding ablative therapy of abnormal biological electrical excitation. In particular, it is designed for treatment of cardiac arrhythmias. In the method of this invention electrical signals are acquired from passive electrodes, and an inverse dipole method is used to identify the site of origin of an arrhythmia. The location of the tip of the ablation catheter is similarly localized from signals acquired from the passive electrodes while electrical energy is delivered to the tip of the catheter. The catheter tip is then guided to the site of origin of the arrhythmia, and ablative radio frequency energy is delivered to its tip to ablate the site.

International Classification:

H04M 336

US Classification:

37926503, 37911206, 37911207, 37911208, 37911209, 37926506, 37926512, 37926605

Abstract:

A multi-site call processing system includes multiple distributed call center sites, and utilizes a load balancing process to distribute calls among the sites for handling by agents. The system generates a multi-site performance score characterizing the performance of the load balancing process. Adjustments may be made in the load balancing process, such as selection of one type of load balancing over another for use at a particular time, based at least in part on the multi-site performance score. The multi-site performance score may be determined using single-site performance measures such as Average Speed of Answer (ASA) and agent occupancy generated across multiple time intervals. The multi-site performance score as generated for a given interval may be, e. g. , a ratio of the maximum and minimum values of a single-site performance measure for that interval. As another example, the multi-site performance score may be in the form of a standard deviation of a set of normalized scores generated for the multiple sites across the specified time intervals.

US Classification:

37926506, 37926508, 37926505

Abstract:

An arrangement ( ) for monitoring contact-center ( ) performance automates the monitoring process by using a database schema ( ) that records ( ) the contact center to be monitored, its skills, the locations where the skills are located (in the case of a distributed contact center), the objective or target value for a given skill attribute (such as average speed of answer, maximum delay, etc. ), the acceptable deviation from the objective (tolerance), the maximum acceptable deviation between locations (in the case of a distributed contact center), the periodicity or frequency of the monitoring, and the comparison operator needed to determine how a given observed or actual value for the skill attribute is to be compared with its specified objective and tolerance. Monitoring is then effected ( ) as follows. Periodically, the contact center is automatically polled for performance data, actual values of the skill attributes are computed therefrom, and the actual values, the objective values, and the tolerances are used in a meta formula to determine the performance metrics.

Appl. No.:

09/219995

Inventors:

Richard Alan Cohen - Wayland MA, US
Robin H. Foster - Little Silver NJ, US

Assignee:

Avaya Technology Corp. - Basking Ridge NJ

International Classification:

H04M003/00

US Classification:

379265, 37926502

Abstract:

A call selection process in a call center is configured to utilize a continuum of skill levels, in one or more categories, for a given multi-skill agent. In an illustrative embodiment, categories of levels are associated with skills supported by the given agent, with each of the categories including a level, e. g. , a numerical value, for each of the skills. The levels are used in a call selection computation that determines which of a number of waiting calls should be delivered to the agent. The categories may include, for example, a speed category including levels indicative of the speed at which the agent can process calls for each of the corresponding skills, a yield category including levels indicative of results likely to be obtainable by the agent for each of the corresponding skills, and a preference category including levels indicative of preferences of the agent for calls requiring each of the corresponding skills. The process may involve selecting different subsets of one or more of the categories in a given set of categories for use at different times, depending on factors such as call volume. The call selection computation may involve, for example, computing a value for each of the skills, as a function of the corresponding level or levels and a wait time measure, e. g.

International Classification:

A61B 5/0444

US Classification:

600517, 600508

Abstract:

Identifying infants at risk for SIDS includes applying electrodes to an infant, receiving electrical signals from the electrodes, analyzing the received electrical signals to measure alternans of a heart of the infant, and identifying whether the infant is at risk for SIDS. A system for identifying infants at risk for SIDS includes an input unit configured to receive electrical signals from electrodes applied to an infant, a processor connected to the input unit and configured to process the received electrical signals to measure alternans of a heart of the infant, and a comparator configured to compare the measured alternans with alternans in a population of infants.
