Abstract: A display badge comprises an outer casing having a cover member, a light source disposed within the outer casing, a source of electrical energy electrically connectable to the light source, a fiber optic strand disposed within the outer casing so that a fiber tip of the fiber optic strand extends through the cover member so as to be visible from the outside of the display badge, and a power switch mounted in the outer casing and including a press button partially extending through the cover member. The power switch is electrically connected to the light source and the source of electrical energy so as to selectively turn on the light source by pressing the press button. The fiber optic strand extends between the cover member and the light source, and configured to transmit the light from the light source to the outside of the display badge.

Abstract: A drinking vessel comprises a waterproof double-walled body member defining an enclosed hollow space therewithin, illumination means and a flexible substrate supporting the illumination means disposed in the enclosed hollow space, a source of electrical energy to the illumination means and a power switch mounted to the double-walled body member and including a mechanical switch pin extendable from and retractable into a bottom portion of the body member. The mechanical switch pin is operable between a first position when the drinking vessel is disposed on a supporting surface, in which the mechanical switch pin is retracted into the bottom portion and the power switch is in an electrically open state, and a second position when the drinking vessel is lifted from the supporting surface, in which the mechanical switch pin is extended from the bottom portion and the power switch is in an electrically closed state.
