According to one embodiment of the present invention, the article or piece of clothing includes a hat having a crown and a bill extending outwardly from the crown. Specifically, Vdd and Vss rails are divided to segregate the ESD current within a circuit, thus isolating the sensitive circuitry from ESD exposure. One or more openings are made in a part of the non-expansion portion. Following receipt of the message, each of the nodes modifies a transmit capability mode by entering a run state during the epochs within the subset to enable communication of network traffic and by entering a low power consumption idle state during the remaining epochs within the time window. The actuator assembly may be operable for opening andor closing the rail clamp. A venturi patient interface circuit is combined with medicated aerosol to deliver continuous high-frequency oscillation therapy.
