ORT Front and Rear Triggers from a Single Gantry using Idris Loops
There are substantial cost advantages in using a single gantry for ORT plaza sites, and Idris can straightforwardly manage the tracking of vehicles from the tag read zone through to the trigger point for all current VES systems. The maximum array length for a 4 loop Idris system is 54ft, which more than accommodates all current VES focal lengths. When both front and rear triggers are required, the situation can get more difficult. This paper discusses some ways of accommodating the required tracking zone using Idris capabilities.
