    Abstract: Provided is a paddle retaining device which may be easily mounted to a stand-up paddle board, wherein the paddle retaining device is specifically configured and adapted to allow a user to quickly and easily securing the paddle to the board. The paddle retaining device may be attached to the board without significantly interfering with the structure and integrity of the paddle surfboard. Along these lines, the paddle retaining device may be secured to the board without drilling holes or making other material modifications to the structure of the paddle surfboard.

    Abstract: A control system for reducing noise or vibration in a target zone. The noise or vibration is produced by a source and transferred to the target zone by a main path. The control system is provided with an actuator, at least one error sensor and a controller. The actuator is positioned to deliver actuated signals into at least a portion of the target zone. The at least one error sensor monitors the residual noise or vibration power in the target zone and produces an error signal representative thereof. The controller receives a reference signal representative of noise or vibration produced by the source, and the error signal representative of the residual noise power in the target zone. The controller analyzes sub-bands of the reference signal and the error signal without identification of a secondary path, and provides drive signals to the actuator to cause the actuator to deliver the actuated signals into the target zone so as to reduce the residual noise power in the target zone.
