Abstract: Methods, apparatus, and systems for an airflow system, wherein the positive applied pressure is maintained at an approximately constant level over a variety of conditions. In one embodiment, a laminar flow is maintained by a foam housing and configuration. The use low air volume is enabled by using a closed system, wherein feedback information from the system is used to control the speed of an impeller. In one embodiment, moisture recirculation and recycling is applied to extract moisture from exhalation and inject the moisture back into the inhalation portion of the breathing cycle.

Abstract: A cooking vessel bracket and handle provides a first handle portion and a second handle portion each having opposing end portions, parallel spaced apart sides and a back defining a channel between the ends. First handle has handle flanges at first end portion and locking seat at second end portion. Second end portion of first handle and first end portion of second handle are pivotally interconnected for first handle to optionally fold into channel of second handle. Spring biased locking pin within channel of first handle protrudes from first handle between the handle flanges for releasable engagement with pot bracket carried by vessel and operatively communicates with a thumb slide for axial movement in channel. Spring biased handle lock in second handle channel releasably engages with locking seat of first handle to secure the first handle and second handle in extended end to end alignment for use.
