Abstract: A system and method is provided for substantially synchronizing sound and smoke in a model train or other model vehicle. In one embodiment of the present invention, a sensor is configured to send a signal periodically to a smoke generating device and a controller, wherein the signal is used by the smoke generating device to produce a particular quantity of smoke. The controller is then configured to receive a signal from a motor, wherein the signal includes information that can be used to identify a rotational position of the motor, or a rotational position of an axle in communication with the motor. The controller then uses the signal from the sensor and the signal from the motor to estimate a transmission lime of a next signal from the sensor, wherein the next signal is used by the smoke generating device to produce a next production of smoke.

Abstract: Control over velocity of a model train may be determined based upon the speed of rotation of a control knob. A processor receives electronic pulses indicating rotation of the knob beyond a predetermined increment of angular distance. The processor calculates the amount of power ultimately conveyed to the model train based not only upon the number of pulses received, but also upon the elapsed time between these pulses. The shorter the elapsed time between pulses, the greater the change in power communicated to the train. Initially, a user can rapidly rotate the knob to attain coarse control over a wide range of velocities, and then rotate the knob more slowly to achieve fine-grained control over the coarse velocity. Utilizing the control scheme in accordance with embodiments of the present invention, in a compact and uninterrupted physical motion, a user can rapidly exercise both coarse and fine control over velocity of a model train.

Abstract: Methods and apparatuses implement a bi-directional model train communications protocol compatible with existing uni-directional communications protocols. In one specific embodiment, the existing uni-directional Lionel Train Master command set is expanded utilizing the checksum error nibble to flag an alternative command signal format. This expanded command set is in turn utilized to transmit a command inquiry signal from the base unit to a specifically addressed element. The addressed element in turn transmits a response based upon the expanded command set. Older model railroad elements not configured to recognize the expanded command set, regard the command inquiry signal as a transmission error and are unaffected. Newer model railroad elements not specifically addressed by the command inquiry signal ignore the command and continue operation.

Abstract: A control circuit which will momentarily apply a pulse of power to the E-Unit solenoid in response to the momentary interruption of power by the transformer or another control signal. The E-Unit rest state is thus with no power applied, eliminating noise and saving power. A seek-to-forward cycling capability is also provided. The overall system has a remote transmitter and a base unit coupled to the train tracks with a receiver. The base unit controls track switching and individual trains through FSK signals transmitted over the track. The base unit also controls a triac switch between the transformer and the track to allow remote control of track power and impose DC offsets on the track power signal.
