A recently granted patent (Publication Number: US11921197B2) discloses a controller for a communication and ranging apparatus that can transmit both data and ranging signals from different antennas. The controller is designed to determine scheduled transmission events for both signals and prioritize one over the other if their transmission events overlap within a predetermined time window. Factors such as distance from the remote device, movement of the apparatus, signal strength, power supply level, historical transmission logs, and user-initiated events are considered in determining the priority signal and secondary signal. The controller can adjust priority scores based on various criteria, such as distance, signal strength, movement, and historical transmission events, to ensure efficient signal transmission.

Furthermore, the patent also covers a communication and ranging apparatus equipped with antennas for data and ranging signals transmission, along with the aforementioned controller. The method outlined in the patent involves determining scheduled transmission events for data and ranging signals, prioritizing one signal over the other based on various factors, and providing signaling to prevent the transmission of the secondary signal when necessary. The method also includes calculating priority scores, adjusting them based on signal strength thresholds, historical data, and user-initiated events, and designating the priority signal for transmission. Additionally, the patent includes a computer-readable medium with instructions for carrying out the method and a mechanism to increase impedance in the apparatus to prevent the secondary signal from reaching the antenna, ensuring only the priority signal is transmitted effectively.
