Abstract: Embodiments of the positive airway pressure (PAP) mask fitting system and method provide a PAP mask fitting process to a specific patient that is as automatic as possible and that returns the patient the most appropriate PAP mask fit. The PAP mask fitting is done in a relatively quick manner. Once a PAP mask fitting has identified a preferred PAP mask for the patient, an appropriate PAP mask can be ordered on demand and is quickly, and possibly immediately, provided to the patient.

Abstract: A lighting system. Implementations may include an AC input power source coupled with a power conditioning and control module adapted output a low voltage high frequency pulse width modulated (PWM) signal. A remote transmission cable may be adapted to carry the low voltage high frequency PWM signal to a remote transformer adapted to convert the low voltage high frequency PWM signal to a high voltage high frequency PWM signal. A charge pump may be included which is adapted to receive the high voltage high frequency PWM signal and increase a voltage of the signal. A gas discharge tube may be coupled to the charge pump. A controller may be coupled to the power conditioning and control module and adapted to operate the gas discharge tube at two or more light intensity levels with the low voltage high frequency PWM signal.

Abstract: A control interface for a visual presentation system. Implementations include a graphical interface including a plurality of parallel lines and plurality of spaces between and adjacent to the plurality of lines that define at least one visual staff. One or more visual notes may be disposed on the at least one visual staff. An output data stream may be included that includes a control sequence of one or more visual element parameters adapted to operate a visual presentation system and corresponding with the one or more visual notes. The output data stream may be coupled with a visual presentation system. One or more music notes on one or more music staffs may be included on the graphical interface adjacent to the at least one visual staff where the one or more music notes are correlated with the one or more visual notes on the at least one visual staff.
