  • Patent number: 9927205
    Abstract: A vortex ring producing gun includes a body defining a first interior volume. The vortex ring producing gun includes a movable nozzle coupled with the body, comprising at least one nozzle opening, and defining a second interior volume. The vortex ring producing gun includes one or more conduits providing fluid communication between said first interior volume and said second interior volume. The vortex ring producing gun includes an energy storage element configured to bias the movable nozzle in a first direction. The vortex ring producing gun includes a latching key configured to hold the movable nozzle in a retained position against the bias from the energy storage element. The vortex ring producing gun includes a movable cocking/firing element configured to interact with the body, the energy storage element, the latching key, and the movable nozzle to selectively cock or fire the vortex ring-producing gun.

  • Patent number: 8469363
    Abstract: A target for use in an underwater target game and a method of the underwater target game are described. The target comprises a body for capturing a volume of gas; and one or more target surfaces positioned to release gas from an impacting vortex ring for capture by the body. A method comprises transitioning a target positioned within a body of water to a hit indication state in response to impact on the target by a vortex ring.

  • Patent number: 6160792
    Abstract: A tone generating circuit comprises a counter circuit having a clock input for receiving a clock signal and a plurality of outputs which generate sequential binary values in response to transitioning of the clock signal; a multiplexer having several inputs, a number of select lines connected to the counter circuit outputs, and at least one output; and a resistor divider network connected to the multiplexer inputs. The multiplexer select lines select one of the multiplexer inputs in accordance with the binary value received from the counter circuit. The multiplexer inputs are connected to different taps on the resistor divider network. The counter selects multiplexer inputs on the falling edge of the clock signal, while the output signal level transitions before the rising edge of the clock signal.
