Patent number: 8655441Abstract: In an exemplary implementation of this invention, a user wears comfortable biosensors. These sensors gather physiological data from the user and transmit this data to another radio-enabled device. This other device may be a mobile phone. The data is further transmitted, via this other radio-enabled device, to one or more networks (such as wireless networks or the Internet). A processor analyzes this transmitted data, in real time, to recognize patterns in the data that indicate the need for therapeutic intervention. Upon recognition of such a pattern, the processor outputs instructions for a transducer to deliver therapeutic stimuli. These instructions are transmitted, over one or more wired or wireless networks, to a transducer which delivers the therapeutic stimuli to the user.Type: GrantFiled: July 13, 2010Date of Patent: February 18, 2014Assignee: Massachusetts Institute of TechnologyInventors: Richard Fletcher, Rosalind Picard, Hoda Eydgahi, Clayton Williams
