This puts us at a decided advantage to our competitors from many standpoints. We are not heavily reliant upon third-party vendors and are therefore not subject to their scheduling constraints. By manufacturing and assembling our own equipment, we are not subject to implementation delays due to equipment non-delivery or other supply problems that our competitors face.
Because Gordon-Darby manufactures equipment on an as-needed rather than continuous basis, substantial flexibility has been designed into our manufacturing process and procedures. The company’s primary manufacturing facility is co-located with Gordon-Darby’s corporate offices and license sales system service depot in Louisville, Kentucky, while additional program-specific facilities are used on an as-needed basis.
Gordon-Darby’s role as an equipment manufacturer also provides the company with significant insight into the hardware and software development and checkout processes that are required whenever I/M program updates or other changes occur.

Gordon-Darby was one of the first in the I/M industry to develop a prototype OBD kiosk, suitable for both self-serve or assisted-serve applications. The company’s patented kiosk was designed for use by either a motorist or an untrained attendant, providing visual and auditory prompts designed to walk motorist or inspectors through complete OBD inspections.

TransMass™, a low-cost software-based testing approach, was developed by Gordon-Darby to predict mass emissions during a transient drive cycle (e.g., the IM240). This patented approach to transient emissions testing uses BAR97-type equipment to determine mass emissions scores without the need to measure total exhaust flow. States can use this solution to generate near-IM240 SIP credits.
We developed the Gordon-Darby VIN decoder by analyzing millions of records from our I/M programs as well as large datasets of additional vehicle identification information obtained from other sources. The resulting database system has been deployed in Gordon-Darby programs to fill in almost all required vehicle information at the beginning of each test based on the VIN entered by the inspector, regardless of whether an online or offline test is being conducted.
The implementation of OBD testing on 1996 and newer model year passenger cars and light trucks by most U.S. vehicle inspection programs has been accompanied by concerns about possible “clean scanning.” This term refers to an illegal practice in which a known clean vehicle is subjected to an electronic OBDII scan in place of the vehicle that is supposed to actually be tested.
Gordon-Darby developed and trademarked the RIMS™ test technology, which involves remote oversight of OBDII kiosk inspections conducted in either decentralized or centralized inspection networks, and data exchange between the remote test kiosks and a centralized database. Using the RIMS™ inspection process / technology, inspection results (including a digital video display of the inspection as it is being performed) are transmitted via any of several possible communications networks (e.g., the Internet, leased phone line, dedicated phone line, satellite connection, etc.) to a central database and oversight location.
