Duos Technologies Selected to Develop Automated Pantograph Inspection System for Chicago METRA.

CHICAGO & JACKSONVILLE, Fla. -- Duos Technologies, Inc. (Duos) has been selected to develop an Automated Pantograph Pantograph

A four-bar parallel linkage, with no links fixed, used as a copying device for generating geometrically similar figures, larger or smaller in size, within the limits of the mechanism.
 Inspection System (APIS Apis (ā`pĭs), in Egyptian religion, sacred bull of Memphis, said to be the incarnation of Osiris or of Ptah. His worship spread throughout the Mediterranean world and was particularly important during the time of the Roman Empire. ) for the Chicago METRA metra /me·tra/ (me´trah) the uterus.

the uterus.
 Electric District (METRA) in Chicago, Illinois, one of North America's largest city transit companies. Divane Brothers Electrical, Inc. is the prime contractor for this project. Duos will execute this project as a turn-key subcontract.

The system will use video analytics developed by Duos' R&D team to continuously inspect METRA's train pantographs and automatically detect suspicious anomalies suggesting defects in the pantographs. As trains pass through strategic inspection points, high resolution cameras will capture digital video images of each pantograph. The images will be overlaid with AEI AEI American Enterprise Institute
AEI Archive of European Integration
AEI Australian Education International
AEI Automotive Engineering International

AEI Albert Einstein Institute
 (Automatic Equipment Identification) tag information from the respective cars passing by. Each high resolution digital pantograph image and corresponding car number will be fused, synchronized, and transmitted to an rvspro[TM] server, a Duos proprietary, remotely programmable digital recording unit where the images are processed, analyzed for defects, and stored on a SQL SQL
 in full Structured Query Language.

Computer programming language used for retrieving records or parts of records in databases and performing various calculations before displaying the results.

The system will flag pantograph defects and will enable trained METRA technicians to zoom in for close-up inspection. Records will be digitally recorded, time-stamped, and the archived video and analytics will be available for forensics See computer forensics. . Real-time and archived streaming video as well as the inspection data will be accessible from remote operator stations through a browser-based interface developed by Duos as part of the system.
