  • Publication number: 20160180587
    Abstract: Apparatus and associated methods relate to determining a fit-quality metric for a mask/face combination based upon a calculated dead-space volume between a virtual mask and a virtual face virtually aligned so as to create an integrity seal circumscribing a mouth and nose region. In an illustrative embodiment, an interactive virtual fitting system may receive a three-dimensional (3D) virtual face associated with a person. The system may retrieve 3D models of various respirators selected by user determined criteria. The system may then compute a fit-quality metric for each of the retrieved 3D models. The potential wearer may then be presented with the metrics for review. The potential wearer may select a respirator based upon these computed metrics. A virtual fitting of many respirators may advantageously reduce the time needed for selecting a properly fitting respirator while simultaneously ensuring that the selected respirator may be comfortable and well fitting.

  • Patent number: 9361411
    Abstract: 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.

  • Publication number: 20160070851
    Abstract: Apparatus and associated methods may relate to a system for predicting a respirator fit by comparing a respirator model in a deformed state to a specific facial model. In an illustrative example, an internal measurement may be calculated between an inside part of the respirator model and the facial model. The internal measurement may be compared against a predetermined threshold to determine a fit of the respirator model, for example. In various implementations, the internal measurement may be a distance and/or a volume between the respirator and facial model. 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.

    Abstract: A process for sensor placement and analysis using a virtual environment includes receiving into a computer processor a model of an area, a position in the model that represents a placement of a virtual sensor, and an orientation of the virtual sensor. A shadow map of the area is generated as a function of the position and orientation of the virtual sensor. The shadow map is used to determine one or more portions of the area that can be sensed by the virtual sensor. The area of the model that is covered as a function of the position and orientation of the virtual sensor is determined, and information relating to the area of the model that is covered as a function of the position and orientation of the virtual sensor is transmitted to an output device.

  • Patent number: 8934017
    Abstract: A system for automatically determining the placement of cameras receives data relating to a plurality of polygons. T polygons represent one or more of a surveillance area, a non-surveillance area, a blank area, and an obstacle. The system selects one or more initial cameras, including one or more initial camera positions, initial camera orientations, and initial camera features, wherein the initial camera positions and the initial camera orientations cause one or more fields of view of the initial cameras to cover at least a part of the surveillance area. The system alters one or more of a number of cameras, an orientation of the cameras, a location of the cameras, a type of the cameras, and a crossover of two or more cameras. The system uses a fitness function to evaluate all of the cameras and all of the camera positions, and selects one or more cameras and the locations and orientations of the one or more cameras as a function of the fitness function.
