A wind resistant module for advertisement curtain is movably mounted to a frame of an advertisement curtain to effectively cushion and counteract wind forces acting on the advertisement curtain and includes: a base, a board, a first resilient cushioning mechanism, and a second resilient cushioning mechanism. The rate of discharge of a dedicated capacitor as measured by a change in the voltage drop thereacross in a predetermined period is used to indicate the magnitude of the conduction current. Plural paired risers, with one riser disposed on each ring member, are aligned with one another along the axis of the connected pipe sections and are each adapted for secure connection to a respective connecting rod for securely coupling the two ring members together and restraining relative movement between the two pipe sections. The exercise device can further include an actuation mechanism coupled to the sliding member where the actuation mechanism can be configured to selectively adjust the position of the sliding member relative to the vertical support member.
