Abstract: A foldable, weather-resistant reference guide for wearing on the arm, torso, or leg. The foldable, weather-resistant reference guide is attached to a soft, flexible keeping member that holds the reference guide in a folded configuration. The keeping member is connected to or comprised of at least one flexible strap such as an elastic strap that encircles the arm, torso, or leg. The reference guide itself is made of a synthetic fiber paper for weather-resistance. The reference guide folds-up when not in use and is held in place by the keeping member so that the reference guide does not interfere with any physical activities such as snow skiing. The keeping member and reference guide can be opened, unfolded, refolded, and closed with only one hand, even while wearing bulky gloves. The entire invention is made of flexible materials that are comfortable, durable, and safe to a person wearing the article and participating in a rigorous physical activity. The reference guide is typically a map.

Abstract: An integral ring which is contains at least 35 weight percent of a precious metal selected from the group consisting of silver and gold and has a porosity of less than 0.1 percent, a Vickers pyramidal hardness of at least about 120, and a tensile strength at least about 60,000 pounds per square inch. The ring has an inner diameter of from about 0.55 to about 0.93 inches, and outer diameter of from about 0.61 to about 1.09 inches, a thickness of from about 0.03 to about 0.08 inches, and a circumference of from about 1.7 to about 3.5 inches. Disposed about and extending around the entire outer surface of the ring is a first annular groove and a second, spaced apart annular groove, and at least 10 adjoining recessed areas are disposed between and communicate with these annular grooves. Each of the first annular groove and the second annular groove has a width of from about 0.01 to about 0.02 inches and a depth of from about 0.008 to about 0.018 inches.
