FRAMINGHAM, Mass. — Audio products maker Bose Corp. has jumped into the trucking sector, unveiling a high-tech seat for over-the-road drivers to combat road vibration.

Iteris Inc., which makes lane-departure warning systems for the trucking industry, said Thursday its fiscal third-quarter profit decreased from a year ago.

When passive radio frequency identification began its rise almost a decade ago, hopes ran high that the new technology, which offers hands-free operation and doesn’t require a direct line of sight, would help to free the shipping industry from labor-intensive bar-code tracking, which often requires handheld devices to read labels and is consequently much prone to human error.

Diamond Phoenix and System Logistics have completed their merger and are now operating as one company under the System Logistics Corp. name, the company said Wednesday.

Navistar Inc. said Tuesday it has acquired some assets from Holley Performance Products, including intellectual property rights for valve technology used on exhaust gas recirculation systems.

BlueGrace Logistics said that it has launched an iPhone application for calculating shipping quotes from multiple carriers.

Automated vehicle tracking is now accessible to more fleets than ever before, as providers pack the technology into small — but powerful — hardware. However, economic and regulatory concerns are keeping older systems firmly entrenched in the trucking industry.

As part of its Comprehensive Safety Analysis 2010 program, the Federal Motor Carrier Safety Administration is introducing its new record-keeping system known as SMS, or safety management system.

Manufacturers and distributors of truck parts and systems are scheduled to discuss the changes coming to the industry during the next decade as they gather in Las Vegas Jan. 18-21 for a pair of heavy-duty events.
