Abstract
An exemplary system and method are disclosed for a respiratory protective device configured to continuously monitor, via an integrated sensor network embedded in the device's frame, the fit or proper particulate-filtering operation of the respiratory protective device. The system can ensure proper operation of respiratory protective device while providing monitoring and tracking of the fit to ensure personal safety for users wearing the device. In some embodiments, the system can monitor, track, and aggregate the data to present via a user interface to the user.
Claims21
A system comprising:
- a respiratory protective device comprising a frame having a contour that maintains a breathable filter covering over a facial region of a user, wherein the frame includes at least one sensor cavity, including a first sensor cavity;
- and
- a sensor network coupled to the respiratory protective device, the sensor network comprising:
- at least one sensor, including a first sensor, wherein the first sensor is disposed within the first sensor cavity to detect pressure or proximity at an interface between the frame and the facial region;
- and
- a signal processing module in operative communication with the at least one sensor, the signal processing module configured to continuously detect the pressure or proximity at the interface between the frame and the facial region via the at least one sensor for continuously monitoring fit or particulate-filtering operation of the respiratory protective device.
A method of monitoring fit of a respiratory protective device, the method comprising:
- providing a respiratory protective device comprising:
- a frame having a contour that maintains a breathable filter covering over a facial region of a user, wherein the frame includes at least one sensor cavity, including a first sensor cavity;
- and
- a sensor network coupled to the respiratory protective device, the sensor network comprising (i) at least one sensor, including a first sensor, wherein the first sensor is disposed within the first sensor cavity to detect pressure or proximity at an interface between the frame and the facial region;
- and (ii) a signal processing module in operative communication with the at least one sensor, the signal processing module configured to continuously detect the pressure or proximity at the interface between the frame and the facial region via the at least one sensor for continuously monitoring fit or particulate-filtering operation of the respiratory protective device;
- continuously monitoring signal or derived values produced by the first sensor;
- and
- providing the signal or derived value to a controller for display or alert generation.
A system comprising:
- computing devices configured to operate with a respiratory protective device, wherein the computing devices are configured to continuously monitor fit of the respiratory protective device on a user,
- wherein the respiratory protective device includes a frame having a contour that maintains a breathable filter covering over a facial region of a user, wherein the frame includes at least one sensor cavity, including a first sensor cavity;
- wherein the frame is configured to house a sensor network coupled to the respiratory protective device, the sensor network comprising (i) at least one sensor, including a first sensor, wherein the first sensor is disposed within the first sensor cavity to detect pressure or proximity at an interface between the frame and the facial region;
- and (ii) a signal processing module in operative communication with the at least one sensor, the signal processing module configured to continuously detect the pressure or proximity at the interface between the frame and the facial region via the at least one sensor for continuously monitoring fit or particulate-filtering operation of the respiratory protective device.
