Abstract:
An apparatus for sensing user input includes a first strain gauge grouping at an inner surface of a housing of a device, and a second strain gauge grouping at the inner surface of the housing. The apparatus includes a circuit coupled to the first and second strain gauge groupings. The circuit: (i) receives a first signal from the first strain gauge grouping in response to user input at the housing over a location of the first strain gauge grouping, (ii) indicates a first type of user input has been received in response to receipt of the first parameter signal, (iii) receives a second signal from the second strain gauge grouping in response to user input at the housing over a location of the second strain gauge grouping, and (iv) indicates that a second type of user input has been received in response to receipt of the second parameter signal.
Abstract:
Systems and methods for using a smart carpet to monitor a health status of an individual. The smart carpet has electronics and a plurality of pressure sensing areas for sensing plantar pressure of the individual. A monitoring computer comprising a processor and a memory including machine readable instructions processes carpet data. A first part of the smart carpet is scanned at a first frequency and a second part of the smart carpet is scanned at a second frequency greater than the first frequency. Plantar pressures are received from the second part of the carpet and the instructions evaluate the plantar pressures to determine at least one of a physical activity and a physiological activity. Where an emergency condition is determined, an alarm is communicated to monitoring personnel.
