Abstract: A vessel includes a container, a bracket, and a brace. The container has a cavity. The bracket extends from the container and includes an arm spaced from the container. The arm has opposed first and second ends, and the arm is connected to the container only at its first end. The brace connects the first end of the arm and the container. A first plurality of structural reinforcement flanges extend along the container between the brace and the second end of the arm. The first plurality of structural reinforcement flanges have curved exterior surfaces.

Abstract: A vessel includes a container, a bracket, a bail and a grip. The container has a cavity configured to hold a liquid. The bracket extends from the container and comprises an arm spaced from the container. The arm has opposed first and second ends, and the arm is connected to the container only at its first end. The bail is pivotally connected to the container and has a grip thereon. The vessel is configured so that the grip has a position that is in contact with the arm, thereby defining, in combination, a composite vessel handle. A method of supporting a vessel includes pivoting the bail so that the grip is in contact with the arm and positioning at least a portion of a hand on the grip.

Abstract: Acoustical voice-feedback systems include headsets connected through a connector or central hub for vocalizing and sound formation assistance. A user's voice is conveyed directly into his or her own ear as well as the ears of each connected user. A central hub allows selective connection of one or more headsets to each other, or allows an instructor to selectively connect an instructor headset to one or more instructee headsets.
