Abstract: An exercise apparatus for attachment and use within a door frame includes a pair of elongated frame elements with each having apertures configured to receive various types of cross bars. The frame elements are designed to be secured to vertical portions of a door frame without interfering with passing through the doorway or closing the door. A cross bar having a length greater than the door width is configured to be received within corresponding apertures among the frame elements. A cross bar has a retractable spring pin protruding from the bar so that the spring pin may engage a frame element to limit axial excursion of the bar. Two such spring pins may be included in the bar, so that with the frame elements including apertures having pin-receiving pockets, one type of bar may rotate freely while another type of bar is prevented from rotation.

Abstract: The present disclosure provides systems and methods for non-destructively estimating the thickness of buried concrete without excavation. An example method may include placing one or more first accelerometers at a plurality of vertical positions below the surface of the ground at an approximate first distance from a vertical edge of the buried concrete each time. The method may further include, for each position in the plurality of vertical positions, generating a dispersive wave in the buried concrete and determining a time of arrival of the dispersive wave at the one or more first accelerometers. The method may further include estimating the thickness of the buried concrete based on at least the times of arrival of the dispersive waves at the one or more first accelerometers.
