Abstract:
1. A method for creating a standalone power regulation and power management device with unpowered output detection capability for a model railroad system comprising: (i) providing a track power source device that conveys applied track control waveforms on two input terminals, (ii) providing a plurality of detection power switch arrangements connected in a DPDT manner, with two parallel detection impedances, connecting between said two input terminals and a track feed element at two output terminals, (iii) providing an additional control logic device connected to said two input terminals and capable of generating timing and control signals, wherein the additional control logic device is connected to said detection power switches through control links, (iv) providing a sample timing and connection device, (v) providing a voltage detector decision logic device connected with said sample timing and connection device, and configured to detect voltages across said detection impedances, and to compare the voltages to said applied track control waveforms, and (vi) providing a detection output signal device connected with said voltage detector decision logic device for outputting occupancy signals, whereby, said additional control logic device is configured to turn off said detection power switches to allow said voltage detector decision logic device in connection with said detection impedances to perform voltage comparisons, and to communicate occupancy detection signals with the detection output signal device.
