Abstract: A Polygonal Unibody Pole Sign is a single piece of cardboard, or other flexible semi-rigid material, designed to enclose a pole, post, or column, that can remain elevated without adhesives, or external support while providing surfaces for advertising, display, or decoration. Installation does not require the Polygonal Unibody Pole Sign to be placed over the top of the pole, column or beam. Instead, the invention is wrapped around the support and kept enclosed by inserting tabs at one vertical end into slots in the other. Flaps with circular or other shaped aperture the same diameter of the support in place along the horizontal ends of each display panel are then folded inward to enclose the support and hold the invention at height. The final installed Polygonal Unibody Pole Sign then presents display surfaces visible from multiple directions, providing 360 degree visibility in the preferred enclosed embodiment.

Abstract: A method and apparatus is provided for protecting a patient during a radio frequency medical procedure. A detector includes an input receiving electrical impulses representing at least one patient parameter to be monitored from at least one shielded sensor connected to the patient. The detector detects at least one of (a) a voltage associated with parasitic current generated during a radio frequency medical procedure and (b) a current generated during a radio frequency medical procedure.
