Abstract

A model train car having a union with a force sensor is disclosed. The force sensor is configured to measure the amount of force acting on the coupler. The information gathered from the force sensor may work in conjunction with a communication link or a local control unit so that realistic train effects can be produced reflecting the change in force being felt by the model train.

Claims (18)

1. A model train car comprising:

a union for connecting to unions of other model train cars, the union comprising a first portion and a second portion;

at least one force sensor connected between the first portion and the second portion of the union and configured to measure the amount of force acting on said union; and

a control unit included in said model train car and adapted to receive force sensor data from the at least one force sensor and to use the force sensor data to produce at least one effect, wherein the effect is selected from a list of effects consisting of smoke, sound and light.

2. The model train car of claim 1 , further comprising a communication link for transmitting the force sensor data to said model train car.

3. The model train car of claim 1 , wherein said force sensor is configured to measure forces in positive and negative directions.

4. The model train car of claim 1 , wherein said force sensor comprises a force sensitive resistor.

5. The model train car of claim 1 , wherein said force sensor comprises a force sensitive strain gauge.

6. The model train car of claim 1 , wherein the control unit is further adapted to use the force sensor data to produce at least one sound.

7. The model train car of claim 1 , further comprising a mechanism within said union that allows force to be multiplied or divided by a ratio.

8. The model train car of claim 1 , further comprising a spring configured to apply a base force to said force sensor in said union, wherein said force sensor is configured to measure forces in positive and negative directions.

9. The model train car of claim 1 , wherein the control unit is further adapted to use the force sensor data to produce at least one quantity of smoke.

10. A model train layout object comprising:

a body;

a force sensor mounted on said body at a position for measuring a force against said body; and

a control unit included in said body and adapted to use at least force sensor data from the force sensor to produce at least one effect, the effect being selected from smoke, sound and light.

11. The model train layout object of claim 10 , wherein the effect comprises sound.

12. The model train layout object of claim 11 , further comprising a bumper mounted over said force sensor to measure the force acting upon said bumper.
