Abstract: Various examples are provided for flat lens antennas and their operation. In one example, among others, an antenna includes electrically thin (W<<?high), highly conducting, TEM mode antenna arms fed at a first end by a balun. The TEM mode antenna arms can be embedded in a spatially varied anisotropic dielectric material. A separation between the TEM mode antenna arms can increase from the first end to a second end where the TEM mode antenna arms transition to resistive card (Rcard) terminations when the TEM mode antenna arms are separated by a distance Hr, where a ratio of Hr to a height (H) of the antenna is in a range from about 0.2 to about 0.8.

Abstract: A deposition apparatus comprises: an infeed chamber; a preheat chamber; a deposition chamber; and optionally at least one of a cooldown chamber and an outlet chamber. At least a first of the preheat chamber and the cooldown chamber contains a buffer system for buffering workpieces respectively passing to or from the deposition chamber.

Abstract: A rotatable self-lam for attachment to an elongate object can be made by variations to conventional self-lams. In some forms, the rotatable self-lam can be made by folding a portion of the head end of the self-lam onto itself to provide an adhesive-free length which is first wrapped around the elongate object during marker application. In other forms, a bifurcated release liner can have a portion proximate the head end of the marker which can be removed to help template or accommodate the fold to create the adhesive-free length or can have a portion proximate the head end which is retained when the portion proximate the tail end is removed such that the retained portion of the release liner provides an adhesive-free surface during application.

Abstract: An apparatus and method for securing a structure and its roof against damage from high winds. A harness of a plurality of strap-like elements runs from or over the roof of a structure to anchors in the ground, with a coarse fabric such as shadecloth attached to and running between the strap-like elements. As the wind velocity increases, the wind pressure against the shadecloth in the area between the eaves of the roof and the ground increases, thus increasing the downward tension on the harness and further securing the roof and structure against damage.
