[SatNews] I.D. Systems, Inc. (NASDAQ: IDSY), a provider of wireless M2M asset management solutions, has received a notice of allowance from the United States Patent and Trademark Office for a patent on an advanced cargo sensing system for dry van trailers and intermodal containers.

Integrating a battery-powered, light-based sensor with an ultrasonic cargo detector, the system is designed to improve cargo sensing accuracy, maximize device battery life, and provide loaded/unloaded data without the need for an external door sensor.

"With this enhancement, our VeriWise trailer management system will provide critical, accurate information on loading-unloading cycle times for dry van trailers and intermodal containers—with cost-effective installation and minimal maintenance—to help our customers maximize their return on investment in their transportation assets," said Kenneth Ehrman, I.D. Systems' chairman and CEO. "We believe this addition to our patent portfolio will significantly enhance our competitive advantages in the dry van and intermodal container segments of our transportation asset management business."

I.D. Systems currently holds more than 75 patents related to its wireless M2M asset management systems.
