Abstract: An acoustic delay measurement apparatus measures an audio delay introduced by an audio system. A programmable delay buffer, which introduces a programmable delay into the audio stream, receives an audio stream from an audio source and outputs a reference signal representing the audio stream. An adaptive filter is responsive to the reference signal to generate an estimate signal to match on convergence of the adaptive filter an audio signal output by the audio system, which is the audio stream delayed by an amount representative of the audio delay introduced by the audio system. A processor including a coefficient analysis block reads coefficients in the adaptive filter after convergence, computes a delay introduced into said estimate signal by the adaptive filter, and adds the computed delay to the programmable delay buffer to provide a measurement of the audio delay.

The counter circuit generates a feedback command for the pulse width modulation device based on the health bit.

Abstract: A rigid or inflatable stand up paddleboard (SUP) conversion kit to provide a stable recreational platform for fishing. diving, hunting, nature photography, birdwatching or other activity. A detachable frame positions a pair of pontoons rearward relative to the SUP to avoid interference with rowing. A rolling storage case stores activity accessories such as diving or fishing equipment. After securing the storage case to the SUP, the case serves as a storage seat. A rear canopy frame may be assembled onto the SUP in order to support a rear canopy to conceal the user; and a front canopy frame may assembled onto the SUP in order to provide additional concealment that may be used for a hunting dog. The various conversion kits are compact and self-contained, and can fit easily in the trunk of a car.

Abstract: A device is temporarily attached to one side of the stern of a boat in order to modify the wake pattern of the boat by effectively making one side of the boat longer than the other side. The delayed wave on the opposite side of the boat from the wake shaping device allows the wave to crest over the natural wave on the side where the device is installed. In one example, the device has a frame with a side surface angled outwardly 12 degrees from the side of the boat, a mounting surface with a platform index notch configured to be positioned over a portion of a boat platform. A wedge shape utilizes water pressure to distribute the load evenly across the fastening side of the device, thereby allowing for a tight fit to the back of the boat.

Abstract: A rowing device conversion kit for a stand up paddleboard (SUP) includes a frame assembly with seat tracks; a seat assembly with a rolling seat; and a rigger assembly. The frame assembly is attached to the SUP with four attachment clamps that each engage a portion of a rail of the stand up paddleboard. Universal attachment clamps are metal coated in non-slip plastic or rubber, so that the clamps conform to the profile of the rails. The clamps are strapped to the frame assembly by wrapping straps around the frame; tightening the straps; and buckling the straps. A locking mechanism keeps the seat in place as the user is climbing on or off the SUP. The rowing mechanism folds up into a bag the size of a golf club bag. The rigger detaches from the framework and breaks down into two pieces.
