Patent number: 11948694Abstract: Mechanisms are provided for compartmental epidemiological computer modeling based on mobility data. Machine learning training of an isolation rate prediction computer model is performed to generate a trained isolation rate prediction model that predicts an isolation rate of a biological population. Isolation data is received which comprises data indicating a measure of mobility of the biological population. The trained isolation rate prediction model is executed on input features extracted from the isolation data to generate a predicted isolation rate. A compartmental epidemiological computer model, comprising a plurality of compartments representing states of a population with regard to an infectious disease, is executed to simulate a progression of the infectious disease and flows of portions of the population from between compartments in the compartmental epidemiological computer model are controlled based on the predicted isolation rate.Type: GrantFiled: May 12, 2021Date of Patent: April 2, 2024Inventors: Vishrawas Gopalakrishnan, Sayali Navalekar, James H. Kaufman, Simone Bianco, Kun Hu, Ajay Ashok Deshpande, Sarah Kefayati, Ujwal Reddy Moramganti, George Sirbu, Xuan Liu, Raman Srinivasan, Pan Ding

Patent number: 8170007Abstract: A packet telephony appliance includes a Euphony network processor that integrates networking and DSP functions to provide a low cost and efficient solution in building a networked appliance. In particular, a Euphony ATM Telephone (EAT) is built around the Euphony network processor. The EAT uses a real-time operating system to provide predictable processing and networking support. The EAT implements IObufs, which provides a unified buffering scheme that allows zero-copy data movement. Furthermore, the EAT uses an Event Exchange (EVX), which provides a flexible mechanism for event distribution, allowing software modules to be composed together in an extensible manner. EVX and IObufs are used together to provide highly efficient intra-appliance communication. The EAT provides a platform that can evolve gracefully to support new protocols, advanced telephony services and enhanced user interfaces.Type: GrantFiled: October 31, 2008Date of Patent: May 1, 2012Assignee: AT&T Intellectual Property II, L.P.Inventors: Mike Chan, Charles D. Cranor, Raman Gopalakrishnan, Peter Z Onufryk, Laurence W. Ruedisueli, Cormac John Sreenan

Patent number: 6671742Abstract: An event exchange mechanism for software systems is disclosed that utilizes a receiver-driven, publisher-subscriber model to overcome various problems in the prior art. The event exchange has a flexible addressing scheme so that a sending module need not be aware of all of its receiving modules. Yet, the event exchange still provides the ability to multicast messages to interested receivers. The system is also uniform since both data and control information can be exchanged using the same mechanism. Mechanisms for flow control are also provided so that a receiver can exert backpressure on a sender; this is especially useful for the transfer of multimedia data.Type: GrantFiled: April 13, 2000Date of Patent: December 30, 2003Assignee: AT&T Corp.Inventors: Charles D.
