Abstract: Computer implemented methods of identifying in-dwelling mobility patterns of a subject are disclosed. The methods involve collecting information from a plurality of sensors in the dwelling of the subject. Contextual variables associated with the dwelling, the subject, and/or the surroundings of the dwelling are determined. A mobility pattern within the dwelling based upon the data and the contextual variables is calculated using a regression model.

Abstract: Systems and methods for determining time a subject spends outside of their home based on signals received from unobtrusive sensors in the home are disclosed. In one example approach, a method for determining time a subject spends outside of their home comprises receiving sensor firing data for a duration from sensors in the home, dividing the duration into epochs, extracting features from the sensor firing data received during the epoch, and classifying each epoch as out-of-home or in-home based on the features extracted from the sensor firing data during the epoch.

Abstract: A system and method for conducting a clinical trial of a medical treatment of human patients. The system uses an array of sensors in the patient's home for substantially continuously monitoring one or more objective functions of the patient. The monitored objective functions of the patient are compared against a baseline set of data for the monitored objective functions for the patient or a set of patients. The comparison includes detecting a trend of deviation between the one or more monitored objective functions of the patient and the baseline set of data. The trend of deviation can be correlated with an application or nonapplication of the medical treatment to the patient.
