Vehicle wireless alarm system
First Claim
1. A vehicle wireless alarm system comprises a front car subsystem installed in a front car and a rear car subsystem installed in a rear car;
- the front car being in front of the rear car;
wherein the front car subsystem comprising;
a reverse car sensor and a brake car sensor;
an alarm source receiving signals from the reverse car sensor and the brake car sensor;
an oscillator receiving signals from the alarm source for mixing the receiving signals with carriers signals;
an encoder receiving signals from the oscillator for encoding the receiving signals;
an amplifier receiving signals from the encoder for amplifying the input signals to have a larger power for transmission; and
a transmitter for receiving the signals from the amplifier for emitting the receiving signals wirelessly as emitting signals;
the rear car subsystem comprising;
a receiver receiving the transmitting signals from the transmitter;
an amplifier receiving signals from the receiver for amplifying the signals;
a decoder for receiving signals from the amplifier for decoding the receiving signals;
an output device receiving signals from the decoder and outputting the receiving signals; and
an alarm device receiving signals from the output device and emitting alarm signals;
wherein by above system, a driver in the rear car knows that the front car now reverses or brakes.

Abstract
A vehicle wireless alarm system comprises a front car subsystem installed in a front car and a rear car subsystem installed in a rear car. The front car is in front of the rear car. The front car subsystem comprises a reverse car sensor and a brake car sensor; an alarm source; an oscillator; an encoder; an amplifier receiving signals; and a transmitter for emitting the receiving signals wirelessly as emitting signals. The rear car subsystem comprises a receiver receiving the transmitting signals; an amplifier; a decoder; an output device and outputting the receiving signals; and an alarm device receiving signals from the output device and emits alarm signals. By above system, a driver in the rear car can know that the front car now reverses or brakes.
