Abstract: A vapor-dispensing device exhibiting a range of evaporation rates corresponding to a discernable range of sensory fragrance intensity levels. The vapor-delivery device includes one or more control structure (e.g., a heat control, a vent control, and/or the like) configured to allow a user to specify the evaporation rate of the vapor-dispensing device over a continuous or discretized range of values. In accordance with another aspect of the invention, the two extremes of operation correspond to a range of sensory fragrance intensity values that span at least three minimum perceivable intensity zones.

Abstract: An improved jewelry provides a body having an enlarged dimension at one end that prevents a ring from sliding off the body and a smaller dimension at a second end that readily receives the ring thereover. A chain is provided at the first end so that the body and chain with the ring forms a bracelet or necklace and the chain simultaneously secures the ring from inadvertent removal over the second end. The body can adopt a wide variety of conformations and configurations such as solid, hollow, tapered, discontinuous, and the chain can be secured through an opening that passes through the body or a separate eyelet or hook that forms an opening is provided at the first end to allow the ring to be advanced over the body before the chain is secured thereto. The body likewise can be formed of various materials such as precious metals, ceramic, plastic, porcelain, gem stone, shell, stone, or wood and/or the body may be unadorned or can be ornamented with etchings, gem stones, engraving, surface texture, color, etc.
