Abstract: Respiratory assemblies are disclosed that include first and second respiratory components and a latching mechanism. The latching mechanism is capable of engaging at least one retaining feature of a respiratory component, thereby impeding disengagement of the first respiratory component from the second respiratory component. Upon application of force to the actuator, the at least one latch is capable of disengaging from the retaining feature, thereby allowing disengagement of the first respiratory component from the second respiratory component. Respiratory components including or adapted to work with such latching mechanisms are also disclosed.

Abstract: A cable testing method includes a tester that includes at least one connector electrically coupled, such as by conductive traces, to a computer. Both ends of the cable are connected to the at least one connector. The computer then sends a signal to one of the conductive traces of the conductor, at one of the ends of the cable, while at the same time monitoring for a signal at the other contacts of the conductor that are in contact with conductive traces of the cable. The process of sending power while monitoring may then be repeated for other of the conductive traces of the cable, for example until substantially all of the conductive traces of the cable are tested. The process of testing multiple of the conductive traces sequentially may be performed automatically by the computer, allowing performance of the cable to be tested quickly, completely, and accurately.

Abstract: A respiratory device includes a face seal and a unitary body that forms an interface with the face seal and includes a lens and a chassis. The chassis includes at least one port for fluidic connection.
