Patent number: 9687195Abstract: A wearable platform embodied in a belt or patch provides physiological monitoring of soldiers during field operations or trauma victims at accident sites and makes health state assessments. The platform includes sensors for heart rate, body motion, respiration rate and intensity, and temperature and further contains a microprocessor and short range transmitter. An analog circuit running an algorithm obtains the R-wave period from the EKG signal and produces electrical pulses with the period between pulses corresponding to the R-wave period. A rule based processing engine having an evaluation algorithm is capable of making a medical evaluation of subject condition and determines a confidence level for the evaluation. The rules are subject to variation depending upon the subject population. The information is communicated wirelessly to a local hub for relay to a remote monitor.Type: GrantFiled: October 8, 2013Date of Patent: June 27, 2017Assignees: THE UNITED STATES OF AMERICA AS REPRESENTED BY THE SECRETARY OF THE ARMY, THE GENERAL HOSPITAL CORPORATIONInventors: Nathaniel M. Sims, Nhedti Colquitt, Michael Wollowitz, Matt Hickcox, Michael Dempsey, Reed J. Hoyt, Mark J. Buller, John S. Ames

Patent number: 8491493Abstract: A method and system for assessing the health status of a patient, such as the asthma status of a patient, provides an asthma status score and a confidence rating indicative of the score's reliability using continuous real-time data. In some embodiments, the assessment comprises a multidimensional analysis in which asthma status scores and respective confidence ratings are generated for multiple individual asthma health dimensions as well as a summary asthma health dimension indicative of overall asthma health. In some embodiments, the individual dimensions include an environmental trigger dimension based on sensor-based environmental data, a physiological burden dimension based on sensor-based physiological data, a medication adherence dimension based on patient diary data and a perceived symptom dimension based on patient diary data.Type: GrantFiled: June 29, 2012Date of Patent: July 23, 2013Assignee: Sharp Laboratories of America, Inc.Inventors: Nhedti Colquitt, Deepak Ayyagari

Patent number: 8085145Abstract: A personal environmental monitoring method and system and a portable monitor for use therein permit real-time mobile monitoring of environmental conditions in the immediate vicinity to ensure compatibility with the particular environmental sensitivities of a person being monitored. The portable monitor may be a fully integrated mobile device that provides real-time mobile monitoring of immediate environmental conditions without network connectivity.Type: GrantFiled: April 3, 2009Date of Patent: December 27, 2011Assignee: Sharp Laboratories of America, Inc.Inventors: Yongji Fu, Deepak Ayyagari, Nhedti Colquitt

Publication number: 20100262031Abstract: A method and system classify respiratory phases in a single channel acoustic signal as inspiratory and expiratory using explicit labeling with label verification. In the method and system, a subject explicitly indicates through a user input the start of a respiratory cycle (i.e. start of inspiration). The phase indication is applied to provisionally label several consecutive phases of a single channel acoustic signal as inspiratory and expiratory. A provisional phase rule set is then generated based on characteristic differences between the inspiratory and expiratory phases. The phase indication, provisional labeling and provisional rule set generation steps are then repeated. The two generated provisional rule sets are then compared for a match to verify the accuracy of the subject's phase indications and the ability to automatically recover phase in the event of signal loss.Type: ApplicationFiled: April 14, 2009Publication date: October 14, 2010Inventors: Yongji Fu, Nhedti Colquitt, Deepak Ayyagari, Jingping Xu

Publication number: 20070293781Abstract: A wearable platform embodied in a belt or flattened patch-like central body shaped to conform to the abdomen provides physiological monitoring of soldiers during field operations or trauma victims at accident sites and makes health state assessments. The platform includes sensors for heart rate, body motion, respiration rate and intensity, and temperature and further contains a microprocessor and short range transmitter. The respiration sensor uses conductive ink in a novel manner. A small square of the ink is coated on an arched structure so that flexing of the arch either to increase or decrease its radius of curvature modifies the resistance of the structure. This is utilized to set the unstressed resistance of the arch structure and to allow a greater range of resistance values capable of measuring distortions in different deformations of the arch. The respiration sensor supplements the motion information provided by an accelerometer sensor.Type: ApplicationFiled: November 3, 2004Publication date: December 20, 2007Inventors: Nathaniel Sims, Nhedti Colquitt, Michael Wollowitz, Matt Hickcox, Michael Dempsey

Publication number: 20060030759Abstract: A wireless patient monitor is adapted to communicate with any one of plural medical telemetry networks, each having one or more central stations, where each network is configured to communicate via wireless communications using one of multiple different communications settings. The monitor includes one or more sensor inputs for receiving vital signs data from a patient, a wireless transceiver, and a controller coupled to receive the vital signs data via the one or more sensor inputs and to communicate with a network via the transceiver. The monitor also includes a display device and is controllable by the controller to automatically display a notification to a user of the monitor upon establishing communications with the at least one central station. There is also a method of monitoring a patient and a wireless medical telemetry system.Type: ApplicationFiled: October 6, 2005Publication date: February 9, 2006Applicant: Welch Allyn, Inc.Inventors: Herbert Weiner, James Moon, Nhedti Colquitt, Eric Petersen, William Howell, Kenneth West
