Special Notice NATIONAL AERONAUTICS AND SPACE ADMINISTRATION is soliciting inquiries from companies interested in obtaining license rights to commercialize, manufacture, and market an RFID-Based Rotary Position Sensor. This sensor, developed at the NASA Johnson Space Center, can be used to sense the angular position of rotating systems. It can be implemented in a controller to refine the rotation angle or used as a position/orientation sensor. The sensor is part of a suite of RFID-based technologies developed by NASA to monitor and manage inventory based on passive RFID sensors. It can track bulk levels or discrete quantities of materials within a container without attaching RFID tags to each item. The sensor was initially created for a hand-crank dispenser system but can be used in various applications to sense or control the angular position of rotating systems. Interested parties can submit a license application through NASA's Automated Technology Licensing Application System (ATLAS). No funding is provided by NASA in conjunction with these potential licenses. For more information, visit the NASA Technology Transfer Portal.
