Interfaces for positive pressure therapy having a mask assembly, a headgear assembly and a connection port assembly are disclosed herein. The connection port assembly has a ball joint connection with the mask assembly and includes a quick release button for easily disconnecting the gases source conduit from the mask assembly. The mask assembly may include a bias flow vent that is formed separately and attached to the mask assembly. The headgear assembly encircles the rear region of the user's head and may include at least some portions that are substantially non-stretchable.

A method for connecting piping includes securing a first piping portion to a base. A second piping portion is secured to a rotating portion. The second piping portion is then rotated. While the second piping portion is rotating, the second piping portion is inserted and driven through the first piping portion. A portion of the first piping portion disconnects from the remainder of the first piping portion. After this disconnection, a rotation of the second piping portion is stopped. A solid weld is formed between the first piping portion and the second piping portion.

A container is formed to include and interior region that is configured to receive a product therein and the container is insulated.

A signal processing evaluator and methods that compare a digital waveform of a cardiac signal to a first processed signal generated by a test system such as an EP recorder or an EP mapping system and generates a first finding evaluating how well the test system filters non-cardiac signals or simulated body impedance. A simulator and methods that send cardiac signals including non-cardiac signals or simulated body impedance to a test system and to a signal processing evaluator for evaluation of the test system.

A container is formed to include an interior region and a mouth opening into the interior region. The container includes a floor and a side wall coupled to the floor to define the interior region between the floor and the side wall
