Abstract: A suspended tray apparatus for avoiding spillage while carrying a single open container of liquid such as a mug of coffee or a cup of tea. The apparatus of the present invention is comprised of a tray on which the beverage is placed and a rigid element extending from the side of the tray and curved such that the outer end is centered above the tray and container; a hole or other method of attaching a cord or chain to the upper end of the rigid element, allowing the tray to hang from a loop or handle, held by a person, at the upper end of the chord or chain.

Abstract: A magnetically actuated amusement device includes a supporting structure having a fulcrum which pivotally supports rigid suspending elements each having a permanent magnet at its outer end. The magnetic swinging elements are arranged in an arc, sharing a common fulcrum, such that they will repel neighboring swinging elements in the arc, the motion of the swinging elements being constricted to swinging in the plane containing the arc.

Abstract: A method providing an online environment for a user to interact with a decision tree. The method includes operating a webserver providing a web-based, interactive decision tree, including communication content. The content is distributed by first transmitting a user interface, including the interactive decision tree, to a web browser operated by a user. The decision tree includes user interactive choices. The web server then receives a message from the user indicative of his selection of one or more choices. The web server then modifies the user interface to incorporate the user's selected choices. The server then transmits the modified user interface incorporating the choices to the web browser operated by the user so that he receives an appropriate response to the choices. One of the user's choices is uploading video content. Also preferred is a technique whereby the user may playback a sequence of content chapters with one selective action.
