Abstract: A respirator mask facepiece thermoformed from a sheet of polymer material includes an opening that is covered by a filter membrane, which may be part of a detachable disposable filter cartridge. The polymer material of the facepiece may be transparent to enable a wearer's lips to be seen. The filter cartridge may include a filter membrane attached to a carrier frame, and may be attached to the facepiece via a set of threads formed on the carrier frame and the facepiece, which draw the cartridge and facepiece together to form a seal therebetween. A latch, catch, or other similar structure may be formed in the facepiece and/or carrier frame to inhibit the cartridge from being inadvertently detached from the facepiece.

Abstract: Methods and devices for identifying available applications for use with hardware of a computer device may include generating an application request with at least one device identification and a hardware identification to determine available applications. The methods and devices may include transmitting the application request to a remote application store. The methods and devices may include receiving, from the remote application store, an available application list with one or more applications having application relationship metadata that identifies compatible usage with the at least one hardware identification. The methods and devices may include presenting the available application list on a display of the computer device.
