VES has placed great emphasis on enhancing the performance and safety of heavy-duty tractor vehicles and has allocated extensive R&D towards the development of innovative products and applications within the industry:
POWER LINE CARRIER (PLC)
Power Line Carrier (PLC) is a reliable, bi-directional communication method, using SAE J2497 communication, that allows the transfer of data and information between the tractor and trailer. PLC communicates using up to 10kBaud and functions through non-intelligent trailers. PLC reduces the amount of wiring required for communication, and is considered a transparent technology that functions in the real world.
The Development of PLC Spread Spectrum Technology for Communication in the Heavy-Duty Trucking Industry:
During the early 1990s, VES considered the problem of interference with data communication signals in commercial vehicles and became aware of a computer chip (used in the home plug-n-play market) that used spread spectrum technology to modulate a data communication signal on several frequencies simultaneously. VES was intrigued by this technology and began an investigation of the potential applicability of this technology to tractor/trailer communication. An extensive R&D effort ensued and by the fall of 1995, VES had developed a communication system utilizing a spread spectrum modulated power line for communication of data within and between tractors and trailers or other towed or driven vehicles (“PLC/SS communication system”). VES filed for patent protection on this PLC/SS communication system on October 14, 1996, and that patent application was published and became available to the public on May 15, 1997.
The National Highway Traffic and Safety Administration (NHTSA) had previously issued a mandate, FMVSS-121, effective as 2001, that all new tractors and trailers, sold in the United States, must be equipped with antilock braking systems providing communication between the tractor and trailer with malfunction warning to the driver. In or about late 1997, an industry-wide consortium, formed to consider the mandate FMVSS-121, and in an industry-wide response thereto embodied PLC/SS technology as an industry standard for satisfying the FMVSS-121 mandate.
VES was granted U.S. Patent No. 6,127,939, entitled “Systems and Methods for Monitoring and Controlling Tractor/Trailer Vehicle Systems” on October 3, 2000. In November 2001, VES lost ownership rights to this patent when the company split from its former business partners.
THE GATEWAY SYSTEM
The Gateway System is a wireless product/system that receives local RF (range of 300 ft.) data from sensors and serially communicates data —to include, but not limited to, unique trailer ID, temperature, pressure, internal battery voltage, etc.—to telematics systems using a RF 433.92 MHz transmitter/receiver, flash memory microprocessor with two (2) RS-232 serial interface ports/connectors. This frequency (433.92 MHz) is standardized in the commercial markets (worldwide) and used in applications for commercial TPMS (Tire Pressure Monitor Systems). The RF 433.92 MHz sensors/transmitter(s) have received FCC approval.
The second generation Gateway integrates a PLC (Power Line Carrier) SAE J2497 communication daughter PC board to the Gateway mother PC board which allows the collection of data over the SAE J560 Seven (7)-pin connector (existing vehicle wire conductors) from the trailer to the tractor. This offers a more complete product offering to fleets/customers.
The Gateway System was developed in collaboration between VES, Inc. and IMI, previously known as International Marketing, Inc.

JJr. - SAE J1708/1587 TO RS323 INTERFACE
JJr. is a firmware and/or software package/product that converts SAE J1708/1587 serial communications — such as engine oil level, engine oil temperature, engine oil pressure, engine coolant temperature, engine coolant level, battery voltage, average fuel economy, instantaneous fuel economy, engine fault code, Vehicle ID, odometer, throttle position, road speed, and engine speed — into RS-232 Communications. The JJr. can be utilized as an independent/standalone product (electronic module consisting of firmware & software) or it can be incorporated into other products.
SafeNut improves the retention of the clamp load and electrical conductivity in electrical, electronic, and mechanical applications by integrating multi-rise cam surfaces onto the locking surface of a nut. The SafeNut can be paired with a NORD-LOCKTM washer to offer a simple and effective fastening solution. The initial SafeNut product is designed to fit Group 31 battery posts and targets electrical systems in the trucking, marine, and off-road industries. Vehicles in these industries demand secure electrical connections that ensure stable torque and positioning. Over time, the clamp load connectivity will not be loosened by variables such as vibrations, shock and thermo cycling.
Patent: US D581,778 & D604,600
Torque-Load and Vibration testing was successfully performed by Nord-Lock Inc. in accordance with DIN65151 to determine whether the SafeNut and NORD-LOCK® washer could hold a battery terminal securely. No movement was observed.

VESPLEX™ IR (IRIS®)
VESPLEX™ IR technology (that was to be marketed under the IRIS name) was a dynamic communications system that used infrared (IR) technology to wirelessly extract/transmit data between a vehicle and a PC once an infrared connection was made. The VESPLEX™ IR technology evolved from an earlier concept, known as VESPLEX™, originally derived from VES’ research and development into multiplexing tractor/trailer connectors. VESPLEX ™ enabled a much broader range of communications in a variety of applications that previously required wired communications between a vehicle and a base station. The system consisted of an infrared transceiver that allowed for two-way communications between PC based software applications and the SAE J1708/1587 diagnostic data port on most heavy-duty vehicles. Unlike RF (radio frequency), which has a wide range of transmission, IR has a narrower and more defined spectrum that could be increased or decreased to target a specific receiving zone(s). Thus, infrared allowed for peripheral physical mounting, yet generated accurate, specific, selected isolated data transmission(s) and reception(s).
Applications included but were not limited to: Asset Tracking (e.g. fuel economy, speed, etc.); Fault Code Monitoring; Vehicle Service Diagnostics; Automatic updating of Vehicle/Engine Software/Computers.
