Abstract: In some examples, a system includes a respirator; a sensor operatively coupled to the respirator comprising: an electric circuit configured to determine a change in at least one electrical characteristic of a sensing element, wherein the change in the at least one electrical characteristic is based at least in part on detection of a particulate matter; and a computing device configured to: output for display at least one graphical element in a set of graphical elements; in response to receiving the data that is based at least in part on the change in the at least one electrical characteristic of the sensing element, determine, without counting particles of the particulate matter, whether the fit test was satisfied; and in response to the determination whether the fit test was satisfied, perform at least one operation that is based at least in part on the determination whether the fit test was satisfied.

CPC classification number: G06T19/20 , G06T2219/2021
Abstract: A method for determining personal protective equipment (PPE) comfort for an individual wearer includes defining a first anatomical shape data representative of an anatomical area of the individual wearer prior to donning a PPE, a second anatomical shape data representative of the anatomical area of the individual wearer after donning the PPE, and comparing the first anatomical shape data with the second anatomical shape data. The method further includes determining a soft skin tissue deformation at a plurality of predetermined anatomical positions based on the comparison between the first anatomical shape data and the second anatomical shape data, and determining a displacement comfort threshold (CTd) value based on the soft skin tissue deformation. The method also includes determining a pressure pain threshold (PPT) value, and determining a comfort metric based on the PPT values and the CTd values. The method also includes generating a notification corresponding to the comfort metric.

Abstract: In some examples, a system includes a respirator configured to be worn by a user; a sensor operatively coupled to the respirator; and a computing device comprising a memory and one or more computer processors, the memory comprising instructions that when executed by the one or more computer processors cause the one or more computer processors to: in response to receiving data from the sensor, determine, during at least one action that is performed by the user and that corresponds to at least one graphical element, that the fit test was not satisfied; determine, based at least in part on particular context data associated with the fit test, at least one remedial recommendation to satisfy the fit test; and output for display the at least one remedial recommendation to satisfy the fit test.
