    摘要： A kayak seat is provided that includes a seat base, and a seat pan supported by, and attached to, the seat base. The seat pan is made from a flexible material such that the seat pan is configured to be adjustable. The seat pan is configured to support the pelvis and thighs of a user seated in the seat pan. A seat back is attached to the seat base. A first adjustment mechanism is configured to adjust a position of the seat pan from a single point of adjustment. A second adjustment mechanism is configured to adjust a position of the seat back.

    摘要： An antenna assembly for radio frequency energy is disclosed wherein individual antenna elements making up an array are fed in an improved manner so that the width of a directive beam, or beams, formed by such elements is, or are, maintained substantially constant over a wide band of operating frequencies. The antenna assembly includes a printed circuit lens having a plurality of feedports coupled to a like plurality of the antenna elements through different constrained electrical paths. The desired operating characteristic is attained by disposing radio frequency energy absorbing material of varying length in the constrained electrical paths, to selectively attenuate radio frequency energy to the antenna elements as operating frequency is changed, with the result that the width of the beam, or beams, radiated from the array of antenna elements remains substantially constant over a wide band of operating frequencies.
