摘要:
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.

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.

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.

摘要:
A controller for model trains on a train track is provided. The controller transmits control signals between a rail of the track and earth ground, generating an electromagnetic field which extends for several inches around the track. A receiver in the locomotive can then pick up signals from this electromagnetic field.

A system and method is provided for substantially synchronizing sound and smoke, or the like, 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 (e.g., a count) 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 (or predict) a transmission time of a next (or second) signal from the sensor, wherein the next (or second) signal is used by the smoke generating device to produce a next (or second) production of smoke. In one embodiment of the present invention, the controller does this by (i) using the signal from the sensor to identify a first count from the motor, and (ii) using the first count from the motor (e.g., together with “chuffs” per revolution) to identify a second count from the motor, wherein the second count corresponds to a transmission time of a next (or second) signal from the sensor. The controller then uses the “estimated time” to transmit a signal to the sound generating device, wherein the signal is used by the sound generating device to produce a “chuffing” sound that is substantially synchronized to a next (or second) production of smoke.

An apparatus for controlling operating features of a model train includes a plurality of selection devices, each of which corresponds to a respective operating feature of the train. The apparatus also includes a controller connected to the selection devices of the apparatus. The controller is operative to generate control signals such as digital messages or DC offset signals corresponding to the selection devices. The apparatus further includes a plurality of switches to control the form the control signals take, and a transmitter connected to the controller. The transmitter is operative to send the digital or DC offset messages that are generated by the controller to a receiver located on the train in order to carry out the desired functions. This invention provides for at least a single button output of complex messages.
摘要:
A control and motor arrangement for use in a model train includes a control arrangement integrally constructed with a motor. The control arrangement receives rotational speed and positional information from the motor and uses this information to determine how much power to supply to the motor, thus controlling the rotational speed of the motor. In this way, the control arrangement maintains a constant motor speed, if desired. In addition, the speed and positional information is optionally provided to a sound control arrangement for use in selecting appropriate sound effects.
