Abstract: An internal balloon projector includes a body insertable through a balloon opening having a power module and a projection module. The projection module receives electrical power from the power module and is operable to project an image onto an inner surface of the balloon when inserted therein. A balloon assembly includes a balloon with the projector inserted therein. The balloon is inflatable via an inflation passage formed within the body, and can be deflated and reinflated. The internal balloon projector can sequentially project multiple images on the inner surface of the balloon.

Abstract: A gyroscopic motion feedback device utilizes one or more pairs of masses mounted on a common axis but independently rotatable to allow rapid variation of the gyroscopic force produced thereby. A sensor detects motion of the mount and a controller uses the detected motion to vary the relative rotational speed of the masses. The device provides haptic feedback where the mount is used to the control the interaction of an objection in a virtual environment, with the controller further varying the relatively rotational speed based on virtual interactions experienced by the object.
