Patent number: 9968283Abstract: A method and related system to, among other things, automatically infer answers to all of the ADL questions and the first four questions of the IADL in the home. The inference methods detect the relevant activities unobtrusively, continuously, accurately, objectively, quantifiably and without relying on the patient's own memory (which may be fading due to aging or an existing health condition, such as Traumatic Brain Injury (TBI)) or on a caregiver's subjective report. The methods rely on the judicious placement of a number of sensors in the subject's place of residence, including motion detection sensors in every room, the decomposition of each relevant activity into the sub-tasks involved, identification of additional sensors required to detect the relevant sub-tasks and spatial-temporal conditions between the signals of sensors to formulate the rules that will detect the occurrence of the specific activities of interest.Type: GrantFiled: November 24, 2014Date of Patent: May 15, 2018Assignee: University of Virgina Patent FoundationInventors: Majd Alwan, Robin A. Felder, Steven W. Kell, Sarah G. Wood, Michael Cvetanovich, Beverly L. Turner, J. William Holman

Patent number: 8551026Abstract: The gait monitor system and method provides various basic gait parameters including step count, cadence, and step duration, in addition to its ability to distinguish between normal, limping and shuffling gait modes, as well as determine falls. Moreover, this gait monitor may be provided with additional sensors, e.g. beam break at the beginning and end of a corridor to estimate average walking velocity (with the distance between the beams known or determined); this enables the calculation of additional gait characteristics such as average step length and average stride length. These parameters can additionally be used to detect various gait anomalies and other diagnostic information.Type: GrantFiled: December 23, 2010Date of Patent: October 8, 2013Assignee: University of Virginia Patent FoundationInventors: Majd Alwan, Robin A. Felder, Steven W. Kell, Siddharth Dalal

Publication number: 20110087113Abstract: A system and method for detecting, monitoring and analyzing physiological characteristics. Signals from a subject are acquired from a suite of sensors, such as temperature, carbon dioxide, humidity, light, movement, electromagnetic and vibration sensors, in a passive, non-invasive manner. The signals are processed and physiological characteristics are isolated for analysis. The system and method are to analyze sleep patterns, as well as to prevent bed sores or detect conditions such as illness, restless leg syndrome, periodic leg movement, sleep walking, or sleep apnea. However, numerous other applications of the invention are also disclosed.Type: ApplicationFiled: August 30, 2010Publication date: April 14, 2011Applicant: WellAWARE Systems, Inc.Inventors: David C. Mack, Steve Kell, Majd Alwan, Robin Felder, Beverly Turner, Sarah Wood

Patent number: 7826983Abstract: Various implementations are disclosed for an instrumented mobility assistance device, such as an instrumented walker. The device includes an attached sensor that is operable to convert an operational action of a user of the mobility assistance device into a sensor signal. A use analyzer is operable to relate the sensor signal to a contact attribute associated with a contact of the user of the mobility assistance device with an underlying surface. The use analyzer is further operable to determine a gait characteristic of the user, based on the contact attribute. The sensor may include a force or moment sensor. The contact attribute may include a foot-initial contact, or a foot-off contact. In this way, gait characteristics of the user may be determined during normal operation of the instrumented device. Also, the sensor may be used to determine a stability measure associated with the device.Type: GrantFiled: January 5, 2007Date of Patent: November 2, 2010Inventors: Majd Alwan, Glenn S. Wasson, Pradip N. Sheth, Alexandre Ledoux, Cunjun Huang
