Procurement Transplant Coordinator. Specially-trained IOPO staff member who has many responsibilities, including discussing donation with the potential donor's family, evaluating potential donors for medical suitability, and coordinating the organ procurement and allocation process.

Positive train controls. The application of digital data communications, automatic positioning systems, wayside interface units (to communicate with switches and wayside detectors), on-board and control center computers, and other advanced display, sensor, and control technologies to manage and control railroad operations. PTC can help reduce the probability of collisions between trains, collisions between trains and maintenance-of-way crews, and overspeed accidents. PTC systems can also improve the efficiency of railroad operations by reducing some train over-the-road delays, increasing running time reliability, increasing track capacity, and improving asset utilization.
