Abstract: A system may include a computer-readable storage media configured to store instructions. The system may also include one or more processors communicatively coupled to the one or more computer-readable storage media. The one or more processors may be configured to, in response to execution of the instructions, cause the system to perform operations. The operations may include measuring a pressure of a volume while a user wears a mask and breathes. The volume may be defined by an interior surface of the mask and a face of the user. The operations may also include determining a differential pressure due to the mask. The differential pressure may be equal to a difference between the pressure of the volume and an ambient pressure of an environment proximate an exterior surface of the mask. In addition, the operations may include determining a mask leakage rate of the mask based on the differential pressure.

Abstract: The liquid capture device has a horizontal support resting upon a support surface having a front edge in close proximity to the edge of a table. A vertical support member has a second connecting top edge. The first and second connecting devices are complementary to each other. On the lower portion of the vertical support member is a liquid receiving means. The liquid receiving means is located under a spigot so any dripping liquid is captured. The liquid receiving means may also include a corrugated floor. In one embodiment, the vertical support member can be removed from the horizontal support member to empty excess liquid. The connecting means may be a hooking member over a pin; or a magnet. In another embodiment, the connecting means may be a hinge and pin or a flexible hinge. This allows the vertical member to rotate for liquid to flow out through an exit.

Abstract: A fluid capture apparatus comprises a fluid-receiving body, a drain member, a generally flat support body and a fluid-channeling extension body. The fluid-receiving body has an open end and a bottom end. A fluid reservoir is defined between the open end and the bottom end. The drain member is attached to the fluid receiving body and communicative with the fluid reservoir for enabling fluid within the fluid reservoir to pass through the drain member. The fluid-channeling extension body has a first end thereof attached to the support body and a second end thereof attached to the fluid-receiving body. The fluid-channeling extension body includes a front face and spaced apart fluid guide members. The spaced apart fluid guide members protrude above the front face and extend at least partially between the support body and the fluid-receiving body thereby providing means for channeling fluid into the fluid reservoir of the fluid-receiving body.
