Patent number: 11918063Abstract: A strapless face mask device comprised of a hollow plastic frame that is covered by a sleeve or protective covering. The body sleeve or covering protects the face, nose, mouth and chin area of the wearer such that any respiratory droplets from the wearer are prevented from entering into the surrounding environment and potentially infecting other individuals. Further, the personal protection device has at least one and preferably two tightening mechanisms that allow a wearer to tighten or loosen the seal that the frame makes with their face. Each tightening mechanism may receive a cable that runs within the hollow frame via a spool within each mechanism. When each spool is rotated, the cable upon each spool is tightened or loosened which in turn increases or decreases the convex angle of the frame to tighten or loosen the seal of the frame against the face of the wearer.Type: GrantFiled: July 27, 2021Date of Patent: March 5, 2024Inventor: Donovan Hill

Patent number: 9361411Abstract: Apparatus and associated methods may relate to a system for predicting a respirator fit by comparing a specific respirator model to a specific facial model in a dynamic position. In an illustrative example, one or more dynamic positions may be generated by actual user movement and/or simulated user movement. For example, a facial model may be generated by altering a static model in view of actual and/or simulated movements. In various implementations, a facial model may be compared against a variety of respirator models from a respirator model database. In some implementations, a 3D representation of the respirator model may be displayed upon a 3D representation of the facial model. In some implementations, a color-coded facial display may characterize areas of comfort and discomfort with respect to the respirator model. For example, areas of comfort and discomfort may be objectively determined in view of an applied pressure by the respirator.Type: GrantFiled: March 15, 2013Date of Patent: June 7, 2016Assignee: Honeywell International, Inc.Inventors: Hari Thiruvengada, Paul Derby, Henry Chen, Hao Bai, Xiaoli Wang, Vicken Sarkissian, Yajun-Edwin Zhang
