  • Toy vehicle with on-board electronics
    Patent number: 7275975
    Abstract: A toy vehicle that measures and displays performance characteristics is presented. The toy vehicle may be configured to measure performance of the toy, such as speed or acceleration, and display a value for the performance characteristic. A display for showing the performance values may be mounted on the body of the toy vehicle. Movement of the toy vehicle may be measured using an accelerometer. The toy vehicle may determine the number of wheel rotations in a set period of time using a rotary encoder. The value of the performance characteristic may be output to a microprocessor onboard the toy vehicle. The microprocessor may use the value in calculations and the result of the calculations, such as a scaled speed value, may be shown on the display screen.
