TL;DR: In this article, an electronic paddle that requires a player to strike an object with the paddle in a certain sequence is presented. But the game circuit and speaker can be switched off at any time.
Abstract: An electronic paddle that requires a player to strike an object with the paddle in a certain sequence. The electronic paddle includes a paddle that contains a game circuit and a speaker. The game circuit is connected to a first pressure sensor located on a first side of the paddle, and a second pressure sensor located on a second side of the paddle. The pressure sensors provide feedback signals to the game circuit when the paddle strikes the object. The game circuit and speaker generate a first sound when the object strikes the first side of the paddle, and a second sound when the object strikes the second side of the paddle. To play a game the player strikes the object with the first and second sides of the paddle in a pattern that is compared by the game circuit with a predetermined sequence. The game circuit and speaker can emit one sound to indicate a successful matching of the sequence, or another sound to indicate that the player did not strike the object in the correct sequence. The sequence can be either generated by the game circuit, or a pre-existing pattern created by another player striking the object with the first and second sides of the paddle.

TL;DR: In this article, a paddle is transformed into a squirt gun by hand turning a nut on the paddle shaft, inserting the bottom end of the paddle into the water and then pulling on the handle to draw a central piston several feet out of the outer paddle shaft.
Abstract: This aquatic sporting device can be used by paddlers of water crafts or boats to paddle their craft or alternately use their paddles as quick-action squirt guns or water cannons with high range and high water exchange rate. The ridged paddle is transformed into a squirt gun by hand turning a nut on the paddle shaft to free the movement of a piston within the paddle shaft, inserting the bottom end of the paddle into the water and then pulling on the paddle handle to draw a central piston several feet out of the outer paddle shaft thereby creating a suction which draws water into the paddle shaft through a nozzle at the bottom end of the paddle blade. The paddle is lifted out of the water and pointed toward the target then the handle is pushed causing the piston to forcefully squirt the water, within the paddle shafts' water chamber, out of the nozzle. The squirt gun can be switched back to paddle mode by pushing the piston back into the outer shaft and re-tightening the central nut. When the piston is fully protracted the paddle can be used as a gaff to pull swimmers toward the boat.
