  • Publication number: 20240065380
    Abstract: A rope tightener includes a bottom seat having a bottom plate and an annular body portion, a roll-up disc having a pivot hole, and a cover having ratchet teeth and fixed to the roll-up disc. The bottom seat has an accommodating space, and a rotation axle disposed in the pivot hole. The annular body portion has at least one pawl corresponding to the ratchet teeth. The cover drives the roll-up disc to rotate or displace between pressed-down and pulled-up positions relative to the bottom seat. When the cover is located at the pressed-down position, the ratchet teeth are engaged with the pawl, enabling the cover to drive the roll-up disc to rotate about the rotation axle in a single direction. When the cover is located at the pulled-up position, the ratchet teeth are separated from the pawl, enabling the cover to drive the roll-up disc to rotate freely.

  • Publication number: 20240072736
    Abstract: An amplifier DC bias protection circuit includes an amplifier module, a filter module and a comparator module. The amplifier module converts an input signal into a non-inverting signal and an inverting signal. The filter module blocks AC signals in the non-inverting signal and the inverting signal, thereby providing a first DC bias signal and a second DC bias signal accordingly. The comparator module is configured to determine whether the absolute value of a DC bias difference signal is greater than a predetermined value, and output a determination signal for deactivating the amplifier module when the absolute value of the DC bias difference signal is greater than the predetermined value. The DC bias difference signal is associated with the voltage difference between the first DC bias signal and the second DC bias signal.
