  • Patent number: 6883280
    Abstract: An apparatus and method for reducing corrosion in post-tension construction is described. An anchor base having an aperture with at two continuously opening surfaces is used with a post-tension tendon. A sheath surrounds the anchor and includes a cylindrical extension having a contact end distal from the anchor base for contacting the tendon as the tendon is inserted through the cylindrical extension and the anchor base aperture. The method positions an anchor base in a selected location so that a tendon end can be inserted into the anchor base to engaged the contact end distal from the anchor base. The tendon is threaded through the anchor base until a selected length extends through the base. The tendon is tensioned, a segment of the tendon sleeve is removed proximate to the anchor base, and a wedge is anchored between the tendon and the anchor base.

  • Patent number: 6459415
    Abstract: An omni-directional, planar folded dipole antenna and related quadrature phase shifter implemented on printed circuit boards (PCBs) having differing properties that are perpendicularly engaged. The planar antenna segment is implemented on a single-sided inexpensive PCB and a quadrature phase shifter and system electronics are implemented on more expensive multi-layer PCBs. The invention reduces cost and improves system reliability because coaxial or like connectors of varying material and installation quality are not required between a planar antenna and a quadrature phase shifter. Planar antenna transmits radio frequency signals in an omni-directional pattern and is capable of receiving signals from remote dipole antennas positioned in arbitrary physical orientations. The quadrature phase shifter provides both phase shifting functions and also converts an unbalanced radio frequency transceiver output signal into a balanced input signal to the planar antenna.
