First Claim
Patent Images
1. An automobile flat tire and blowout alert system, consisting of several pairs of ultrasonic sensors of equal number with tires of an automobile, one micro-processor and several alert indicators, characterized in that:
- said ultrasonic sensor is an ultrasonic distance measuring device made of piezoelectric ceramic, it is placed above a shaft of said tire to protect itself from damage caused by objects on the ground, while keeping at a fixed distance from a center of said tire that allows distance between said sensor and the ground to change with height between said tire and the ground;
a micro-processor lies beneath a dashboard of said automobile, in which one integrated circuit for calculation and contrast and one buzzer for sending out alert signals are attached and alert indicators of equal numbers with said ultrasonic sensors inlay on a surface, said integrated circuit connects each pair of ultrasonic sensor through wire leads for detecting signals and then triggers said circuit of said buzzer and of each pair of said alert indicators, which prompts said buzzer to send out alert signals and put lights of said alert indicators on;
as such, said invention detects variation of height between each tire and the ground with said ultrasonic sensor, and said ultrasonic sensor in turn monitors variation of tire pressure, then, in accordance with a detected status calculated and contrasted by said micro-processor, said buzzer sends out alert signals and triggers each indicative light of said alert indicators so as to protect the driver during driving by maintaining security of said tire.

Abstract
The present invention relates to an automobile flat tires/tire blowout alert system—a detecting system combining a micro-processor and several pairs of alert indicators with an ultrasonic sensor. With the ultrasonic sensor to detect the height variation between each tire and the ground, the system monitors the variation of the each tire'"'"'s tire pressure. Then, after the micro-processor calculates and contrasts the detected status, the buzzer sends out alert signals and commands the alert indicators to signalize for identification, which in turn to maintain the security of the automobile'"'"'s tires and prevent the them from being damaged.
