Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
125 words
A tire abnormal condition alarming system for a vehicle comprising: a remote control device including: a signal receiver for receiving a door unlocking or locking aerial propagation signal from an operating key; a door locking mechanism operated according to the signal reception of the signal receiver, to unlock or lock a door; a signal transmitter coupled to a tire of the motor vehicle, the signal transmitter detecting an abnormal condition of the tire to transmit an abnormal condition detection signal as an aerial propagation signal to the signal receiver; and alarming means for performing a warning operation to inform the occurrence of the abnormal condition of the tire by operating the signal receiver upon reception of the abnormal condition detection signal from the signal transmitter.
Claim 2
Dependent Claim
125 words
A tire abnormal condition alarming system for a vehicle comprising: a remote control device including: a signal receiver for receiving a door unlocking or locking aerial propagation signal from an operating key; a door locking mechanism operated according to the signal reception of the signal receiver, to unlock or lock a door; a signal transmitter coupled to a tire of the motor vehicle, the signal transmitter detecting an abnormal condition of the tire to transmit an abnormal condition detection signal as an aerial propagation signal to the signal receiver; and alarming means for performing a warning operation to inform the occurrence of the abnormal condition of the tire by operating the signal receiver upon reception of the abnormal condition detection signal from the signal transmitter.
Claim 3
Dependent Claim
107 words
A tire abnormal condition alarming system for a vehicle as claimed in claim 1, wherein the signal transmitter includes: at least two abnormal condition detecting switches turned off upon detection of an abnormal condition of the tire; a DC source having one of its terminals grounded through one of the abnormal condition detecting switches; a switching element with a control terminal which is grounded through another of the abnormal condition detecting switches and is connected through bias means to another terminal of the DC source; and an oscillator for outputting the abnormal condition detection signal as an aerial propagation signal when the switching element is turned on.
Claim 4
Dependent Claim
76 words
