Appl. No.:

8/328357

Inventors:

James R. Watts - Woodbridge VA

International Classification:

G06F 1500
B62D 122

US Classification:

36442402

Abstract:

A mobile robot for and a method of producing accurate physical lay-out and reference lines or performing work on a plane surface through cartesian coordinates or angle and distance systems is provided. The mobile robot has an on-board computer, a navigation system, and an emissions system. The robot is provided with a drive, for receipt of a floppy, or an internal drive, that can be programmed by an interested party directly or from a remote location by a plug-in. The program is loaded with locations that require treatment, work or equipment positioning. The robot locates and treats the coordinates with emission means, such as an ink jet type marking system, for workmen or for directly performing work at the coordinates.

Abstract:

Systems and methods may be used to monitor the integrity of a belt of an elevator system. Many buildings nowadays do not have the luxury of being able to regularly take an elevator system out of service to perform a giant magneto-resistance (GMR) scan of an entire length of the belt from which an elevator car is suspended. One method to avoid this inconvenience involves performing GMR scans of segments of the belt during the course of everyday passenger traffic and compiling data associated with different segments into a complete GMR profile for the belt. To determine whether the belt contains an irregularity, the GMR profile may then be compared to one or more baseline GMR profiles that were acquired previously, ideally at a time when the belt was known not to contain any irregularities.
