Abstract: A system and method of an adaptive transmitter for an object detection system having an adaptive transmitter that enables changing power levels to meet health and safety requirements based on proximity information. Adaptive transmitters are placed on gateway pillars of a multi-sensor gateway system using an adaptive transmitter configuration. A patron passes through the center of the gate and always stays far enough away from the transmitters such that the transmitter operates in a high field configuration and remain under appropriate health and safety levels. A patron can also move close to a pillar and enter the second proximity boundary wherein the system would automatically switch to a lower power setting to remain within the appropriate health guidelines. A two-mode power level configuration can be extended to a continuous mode configuration where the power levels are adjusted dynamically. Furthermore, power consumption can be reduced and battery lifetime prolonged.
