First Claim
Patent Images
1. A wireless tire pressure alarming system comprising:
- a plurality of tire pressure transmitters each attached to each car wheel for sensing a tire pressure in each wheel tire and operatively transmitting a tire pressure signal remotely upon sensing a low tire pressure below a predetermined safety pressure value; and
a tire pressure receiver formed in a car and connected with a plurality of alarms each alarm corresponding to one car wheel among all car wheels, whereby upon receiving of a low tire pressure signal sent from one said transmitter corresponding to one said car wheel causing low tire pressure, said receiver will actuate one said alarm corresponding to said car wheel having low tire pressure for warning a car driver for enhancing his or her driving safety;
the improvement which comprises;
said receiver including a plug plugged in a car cigarette-lighter receptacle for powering said receiver for operatively receiving the signal as sent from said transmitter;
said receiver including;
a receiver body;
said plug protruding forwardly from the receiver body and operatively plugged in said car cigarette-lighter receptacle when removing the cigarette lighter from the receptacle for connecting power supply from a car battery through the receptacle;
four LEDs respectively disposed on a front left portion, a front right portion, a rear left portion and a rear right portion corresponding to four car wheels respectively disposed on four portions of the car for optically warning the car wheel causing low tire pressure;
a buzzer formed on said receiver body for sounding an audio alarm for the car wheel having low tire pressure; and
a plurality of selectors each operatively selecting an identification code of one said transmitter attached to one said car wheel to which said transmitter is attached.

Abstract
A wireless tire pressure alarming system includes a tire pressure sensor & transmitter attached to each car wheel for sensing the tire pressure in each car wheel and for remotely sending the tire pressure signal from each car wheel; and a receiver having a plug plugged in a car cigarette-lighter receptacle to be powered by the car battery through such a cigarette-lighter receptacle and for receiving the tire pressure signal from the car wheel; whereby upon detection of a tire pressure reduced below the pre-determined safety pressure value of each car wheel, an alarm will be actuated either by an optical alarm signal or a sound alarm signal for warning the car driver for inflating his or her car wheel for enhancing driving safety.
