Abstract: A self-contained breathing apparatus. The self-contained breathing apparatus comprises a back plate comprising a shoulder strap load portion and a waist belt load portion, wherein the waist belt load portion rotates about an extended axis defined by the junction of the waist belt load portion with the shoulder strap load portion, a shoulder strap coupled to the shoulder strap load portion of the back plate, a waist belt coupled to the waist belt load portion of the back plate, and a bottle of compressed breathable air secured to the shoulder strap load portion of the back plate.

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: 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.

Abstract: A system which may enable users to plan, design and observe various building systems in an abstract and intuitive view, such as with a map view. In this view, virtually all facility information and objects may be displayed as simple shapes (e.g., rectangles). Just by some drag-and-drop, a user may provide shapes and rearrange positions of these shapes quickly to reflect a desired space relationship. Objects (e.g., components, devices, controllers, and the like) may be placed, moved around, and associated with each other on a facility layer or floor. Further, the map view may be used together with a tree view and a list view to provide alternative design ways. Changes made in any of the views may be synchronized with the other views. Various presentations of the facility may be provided.

Abstract: A shoulder mounted hood cooling assembly includes a support, a blower carried by the support, and vents in fluid communication with the blower. The support when worn by a user positions at least a portion of the support adjacent the user's shoulder's and the vents are positioned to direct air exhausted from the blower to a neck or to a head or both the neck and the head of the user.

Abstract: One embodiment of the application provides a method of generating a 3D user interface (UI) in a controller for an appliance in a physical environment. The method includes: abstracting the appliance to obtain to a appliance functionality description having variables of the appliance, operations of the state variables, and relationship among the state variables; converting the state variables into corresponding 3D widgets in the controller, wherein the state variable are mapped respectively into the 3D widgets; laying out the 3D widgets to form the 3D UI in the controller; constructing communication objects in the controller from the state variables, the state variables being mapped into the communication objects; and providing interaction between the 3D UI and the appliance by a communication protocol integrated with the appliance.
