  • System, method and apparatus for supporting and concealing radio antennas
    Patent number: 8035574
    Abstract: A multi-trunk antenna structure that includes a main trunk and a plurality of upper trunks is provided. The upper trunks extend upwardly at a desired angle from the main trunk and provide a desired girth of the structure near the top. A plurality of antennas are attached to desired upper trunks at a desired height above ground level. The antennas can be adjusted to a desire azimuth. The antenna structure can include branches so that it resembles a Eucalyptus tree, an Oak tree, or other type of tree. The trunks of the structure can provide raceways for antenna cabling.

  • Tennis racket and stringing method
    Patent number: 4163553
    Abstract: A tennis racket head is strung with string sections between frame support points formed into zig-zag segments which have multiple junction points with other string sections to hold the strings in the zig-zag pattern. In a preferred embodiment, the segments are arranged in parallel tiers, and weave over and under intermediate strings between junctions. An apparatus and method for stringing the racket is included. A simple tension adjustment can be added to the racket, which adjusts the tension over the entire playing surface.
