Transponder charging apparatus
First Claim
1. In a go-cart having an engine, a ground chassis and a coil providing an AC electrical power supply, and a racing transponder unit including a battery having first and second terminals, means for charging said battery comprising:
- a) voltage rectifying and regulating means;
b) a first wire connecting said ground chassis to said voltage rectifying and regulatory means;
c) a second wire connecting said AC power supply to said voltage rectifying and regulatory means;
d) third and fourth wires connecting said voltage rectifying and regulating means to said first and second terminals of said battery; and
e) housing means defining a space wherein both said transponder and said voltage rectifying and regulating means are at least partially contained.

Abstract
Apparatus for automatically charging a transponder mounted to a go-cart. The transponder charging unit is basically comprised of a housing having a wall which divides its space into first and second compartments wherein a PC board and a transponder are at least partially contained, respectively. A cover plate secures and protects the PC board and transponder within the housing. A wire is spliced into the go-cart'"'"'s coil grounding wire to extract A/C power therefrom and send it to the PC board. The PC board contains several solid state devices to rectify and regulate the voltage. Wires extend from the PC board'"'"'s output to charging contacts operatively connected to the transponder'"'"'s battery, thereby providing a charge thereto. Thus, the transponder'"'"'s battery, is continually being charged while the go-cart'"'"'s engine is running.
