  • Patent number: 5896017
    Abstract: Electronic circuits and methods are disclosed for remote control of a locomotive in a model railroad layout having an interruptible DC power supply coupled to the railroad track. The locomotive motor is isolated from the track so as to allow use of polarity reversals on the track power signal for controlling remote effects in the locomotive such as sound and visual effects. An on-board electronic state generator is provided in the locomotive for maintaining one at a time of a predetermined set of states, at least one of the states having a corresponding remote effect associated therewith. Remote control signals such as a pulsed reversal in polarity of the DC track power signal (PRP) or high voltage pulse (HVP) are used to clock the state generator to a desired state, thereby permitting control of a plurality of remote effects using only the traditional DC power supply interface.

  • Patent number: 5773939
    Abstract: Apparatus and methods are disclosed for transmitting very fast digital DC signals over the track for remote control in a model railroad layout, by selecting positive and negative lobes from the applied AC track power signal. This method allows digital transmission at 120 Hz rate that can be used within a 60 Hz AC system. This is fast enough to be used for Digital Command Control (DCC) and also capable of delivering large power output efficiently without the expense of filtering or exotic electronic control circuits. This method also has low sensitivity to electrical noise and does not generate significant noise during operation. We describe methods of transmitting and receiving positive and negative lobes and methods to extend this technology. We also describe other areas where this technology can be applied such as remote control of appliances connected to any AC power environment such as home or industrial electric power systems.

  • Patent number: 5678789
    Abstract: A model railroad car position indicator includes a sensor receptive to the presence of a model railroad car on a track. Control circuitry determines the location of the car relative to a predetermined position on the track and approves initiation of a model train process if the car is within a range of acceptable positions for initiating the process. A preferred embodiment includes circuitry for determining whether the car velocity is less than a predetermined threshold velocity. In this embodiment, approval of initiation of the model train process is conditioned on both the car position being acceptable and the car velocity being acceptable. An indicator provides feedback to the model train operator for manual initiation of the model train process. Alternatively, the control circuit may automatically initiate the process.

    Abstract: A digital sound reproducing system which produces a plurality of sound effects from digital data stored at predetermined addresses in a digital sound memory. A controller connected to the digital sound memory causes recall of a sound data from a predetermined sequence of addresses when triggered. This recalled sound data is converted into an analog audio signal for reproduction by a speaker. In a first embodiment the digital sound reproducing system is disposed in the car of a model train. Magnets disposed between the tracks trigger corresponding sound effects when the digital sound reproducing system detects passage of the magnets. A speed sensor detects the rotation rate of a wheel of the car to permit sound effects to be synchronous with the rate of speed of the model train.
