1. An apparatus comprising:
- an odometer configured to measuring the horizontal movement of the apparatus in either a first direction or a second direction;
a road surface measuring device configured to generate a first set of data points indicative of a first road surface profile when the apparatus is traveling in the first direction and configured to generate a second set of data points indicative of a second road surface profile when the apparatus is traveling in the second direction, the first set of data points and the second set of data points being correlated depending on the travel direction of the apparatus;
a computation device configured to generate a first plot of the profile of the first road surface from the first set of data points and to generate a second plot of the profile of the second road surface from the second set of data points.

Abstract
A light weight, bi-directional, computerized profilograph is disclosed. The bi-directional profilograph includes an odometer for measuring the horizontal movement of the profilograph in either a first direction or a second direction, and a road surface measuring device for measuring a road surface profile while the profilograph is traveling in either the first direction or the second direction. A computation device is also included for plotting the profile of the road surface versus the horizontal movement of the profilograph while the profilograph is traveling in either the first direction or the second direction.

13. An apparatus comprising:
a computer configured to generate road surface profile reports, the computer comprising; an input port configured to receive horizontal movement information and vertical height information generated during a profile run of the apparatus; a memory, coupled to the input port, and configured to store the horizontal movement information and the vertical height information in an unprocessed form, the horizontal movement information being correlated depending on the travel direction of the apparatus; and a processing unit, coupled to the memory, and configured to receive the horizontal movement information and the vertical height information in an unprocessed form and further configured to generate a road surface profile report from the horizontal movement information and the vertical height information using a processing algorithm. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. An apparatus configured to measure the surface profile of a first run and an adjacent second run of a road surface, the apparatus comprising:
-
a first measuring device configured to measure the horizontal movement of the apparatus along the road surface; a second measuring device configured to measure the vertical profile of the road surface when the apparatus is moving horizontally along the road surface; and a computation device, coupled to the first measuring device and the second measuring device, the computation device configured to generate a first surface profile plot of the first run of the apparatus along the road surface and to generate a second surface profile plot of the second run of the apparatus along the road surface, wherein the second plot is correlated to the first plot, without having to return the apparatus to the starting point of the first run to begin the second run or turning the apparatus around to start the second profile run. - View Dependent Claims (27, 28, 29, 30, 31, 32)
