Remote control systems for toy vehicles, and the like
First Claim
1. A remote control system for an instrumentality to be controlled comprising:
- a controller for producing at least one analog control signal;
analog/digital converter circuitry connected to the controller for converting the analog control signal into digital control signals representing at least one command to be transmitted to the instrumentality;
encoding circuitry connected to the analog/digital converter circuitry for processing the digital control signals from the analog/digital converter circuitry into successive words containing binary coded bits representative of said digital control signals;
cyclic signal generating circuitry connected to said controller for introducing a cyclic signal to said controller to cause said encoding circuiry to produce a predetermined number of such successive words for each cycle of said signal with the binary value of the binary coded bits in the words generated during each of the cycles being dependent upon the value of said analog control signal; and
means connected to the encoding circuit for transmitting the successive words to the instrumentality.

Abstract
A remote control system in which control signals from a transmitter are sent to receivers mounted in a number of cars, or other vehicles. Manually operated controllers for the respective vehicles are connected to the transmitter. The transmitter is capacitively coupled to the receivers, and there is no conversion of the control signals into modulated radio frequency carriers in the embodiment to be described. The track on which the cars are propelled is coated with a conductive material which forms one plate of a capacitor, the other plate being formed by a second conductor which extends around the track and which is spaced and insulated from the conductive coating. Under some circumstances, the second conductor may be ground. Each car forms two additional capacitor plates within the first capacitor to provide capacitive coupling between the transmitter and the cars. The data transmission system at the transmitter uses a type of pulse code which permits the individual cars to be controlled by their individual controllers independently of one another, and which enables various commands to be transmitted to the individual cars so that each car may be steered, and so that the speed of each car may be controlled.
