Abstract: An ear tip for a sound device. The ear tip has an asymmetrical arrangement which more closely aligns with a user's ear canal. The ear tip includes an ear tip base, ear tip shaft, and a first group of low-profile flanges. The ear tip is arranged along an ear tip central axis. The ear tip has a sound tube connection and a sound channel which extends through the ear tip base and ear tip shaft. The first group of low-profile flanges are spaced along an ear tip shaft axis, and extend radially from the ear tip shaft in perpendicular alignment to the ear tip shaft axis. A first flange, a second flange and an intermediate flange are provided. Each flange is constructed of a flat roof with a downwardly transitioning radial wall. There is a space between each of the flanges. The flanges seal against the ear wall to attenuate sound and reduce resonance.

Abstract: A sound amplification system which has a sound application ear device operating a programmable control board. The control board provides a low pitched signal and a high pitch signal. It also provides a mono audio signal and a stereo audio signal and a recharging current. The recharging current charges the rechargeable battery. The rechargeable battery provides power to the device. A microphone is also provided and it transmits exterior sound signals to the programmable control board. An earphone operates with the device and can receive the stereo audio signal. The mono audio signal is amplified and broadcast through a first speaker in the ear device. The stereo audio signal is amplified and broadcast through a second speaker in the earphone.

Abstract: A hearing amplification system. The system has a rechargeable hearing amplifier and a portable charging system. The rechargeable hearing amplifier has a rechargeable battery, a sound amplification portion which will receive sound waves from between 200 to 6000 Hz amplifies sound waves to between 40 dB and 60 dB and broadcast the sound waves to a human user. The rechargeable hearing amplifier also has an ear engaging membrane which is designed to secure to a human ear. The amplification system also has a portable charging system to charge the rechargeable battery in the rechargeable hearing amplifier. The portable charging system has a single 1.5 V battery charger, and alternatively an AC adapter providing 3 V DC. The portable charging system has a seat for charging the rechargeable hearing amplifier and at least one seat for the ear engagement membrane.

Abstract: A marination device for marinating a food item. The marination device includes a flavor injector configured to inject during a first stage marinating process liquid preparation into the food. A vacuum canister configured to pressurize to a negative pressure state during a second stage marinating process the food. The food is vacuumed to remove the air in the food, and re-pressurized to an atmospheric state in the vacuum canister to imbue the liquid preparation into the food.
