Abstract: A small number of transmissions are performed at a sufficient number of frequencies and power levels so that a correlation between frequency, measured power, and detector values is established. Once a correlation is established, the wireless transmitter employs the measured data and calculates target detector values for all supported frequencies and at all supported power levels, eliminating the need for one frequency and one power level at a time iterations with a host device. Using the calculated target detector values and closed loop transmissions, the radio self-calibrates. Once employed in the field, the wireless transmitter can utilize measured changes in signal strength to determine when to re-calibrate, and using measured values from other network components, can employ the methodology of the present invention to self-calibrate, eliminating the need for field re-calibrations.

Abstract: A method and control system are provided for controlling a modular conveyor system, which may be networked together with other such systems in order to implement a control strategy for a modular conveyor system. The control system comprises a communications port for interconnection of the control system with a network for sending outgoing addressed data to other devices on the address-based network and for receiving incoming addressed data from other devices. The control system further comprises a logic system, which may receive a signal from an object sensor and provide a control signal or output adapted to control activation of a motorized roller assembly, based on an input signal from the object sensor or the communications port. The logic system may provide for single step operation whereby system troubleshooting may be facilitated, and in addition may provide situation aware and output value source selection functionality.
