Abstract: An aircraft includes a fuselage assembly including a first elongated structural member formed of electrically conductive material, at least one wing assembly including a second structural member formed of electrically conductive material, at least one horizontal stabilizer assembly including a third structural member formed of electrically conductive material, and at least one vertical stabilizer assembly including a fourth structural member formed of electrically conductive material. The wing assembly, the horizontal stabilizer, and the vertical stabilizer are each interconnected with the fuselage assembly in a flight configuration normal to the fuselage. The first, second, third and fourth structural members are electrically insulated from one another. An electronic communication device within the aircraft is configurable for selective electrical interconnection of two or more of said structural members to form a dipole or monopole type transmitting/receiving antenna.

Abstract: Apparatus, particularly adapted to covering and protecting the ankles of off-road bicycle riders from injury, has an ankle-length sock made of elastic knitted fabric covering each of the rider's feet and a pair of bicycling shoes having low-cut uppers. A thin guard of a hard, flexible material passing around the rider's ankle is retained at the outside of each sock, extending from the top of the sock to a line proximate the top of the shoe upper so as to protect the inside and outside of the ankle joint.
