Publication number: 20230343040Abstract: Augmented reality-based training systems are described that dynamically construct and render AR content based on physical attributes of a user to train the user to correctly fit one or more articles of a personal protective equipment (PPE) onto the user's body. In some examples, an AR system includes a display and a computing device having a memory and one or more processors. The memory includes instructions that when executed by the processors simulate a fitting of a PPE to a worker by capturing at least a first image of the worker; selecting a digital model of the PPE; determining an alignment of the digital model of the PPE to the first image of the worker; and outputting for display augmented reality content comprising a composite of a least a second image of the worker overlaid with the digital model of the PPE in accordance with the determined alignment.Type: ApplicationFiled: May 5, 2021Publication date: October 26, 2023Inventors: Claire R.

Publication number: 20230290091Abstract: 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.Type: ApplicationFiled: July 28, 2021Publication date: September 14, 2023Inventors: Ambuj Sharma, Claire R.

Patent number: 11748983Abstract: Example PPE fit systems are described that verify that a current fit of a PPE on a wearer is consistent with a previous fit test of the PPE on the particular wearer. During a fit test of a PPE, an image capture device captures an image of the wearer with the PPE that represents a verified reference for a fit of PPE of a same or similar type on the particular wearer. During a verification check, an image capture device captures an image of the wearer with the PPE. Visual features of the fit test image are compared with visual features of the verification image to determine whether the fit of the PPE on the wearer is correct. Differences between the visual features are alerted to the user, such as for correction, adjustment, or retest.Type: GrantFiled: May 14, 2019Date of Patent: September 5, 2023Assignee: 3M Innovative Properties CompanyInventors: Claire R.
