System of apparatus for monitoring a tire condition value in a pneumatic tire
First Claim
1. A system of apparatus for monitoring at least one tire condition value in each of a plurality of pneumatic tires of a moving vehicle, each of the tires having associated therewith a passive electronic tire tag for sensing the at least one tire condition value, and each of the tire tags responsive to an interrogation signal transmitted thereto to transmit a data modulated signal representative of the at least one tire condition value, the monitoring system comprising:
- (a) portable ramp apparatus for supporting thereon the moving vehicle;
(b) vehicle sensing apparatus for sensing the presence of the moving vehicle;
(c) tire pressure sensing apparatus embedded in the ramp apparatus for detecting the presence thereon of a tire of the moving vehicle;
(d) transceiver apparatus including transmitter antenna structure and receiver antenna structure respectively embedded in the ramp apparatus for transmitting the interrogation signal to respective tire tags when the tire pressure sensing apparatus detects the tire of the moving vehicle; and
(e) receiving the respective data modulated tire tag signals independently of one another from different tire tags and demodulating the respective data modulated tire tag signals and digitizing data therefrom.

Abstract
A system for monitoring at least one tire condition value in each of a plurality of pneumatic tires of a moving vehicle, wherein each of the tires has associated therewith a passive electronic tire tag for sensing the at least one tire condition value and is responsive to an interrogation signal transmitted thereto to transmit a data modulated signal representative of the at least one tire condition value. The monitoring system includes portable ramp apparatus for supporting the moving vehicle, portable vehicle sensing apparatus for sensing the presence of the moving vehicle and tire pressure sensing apparatus embedded in the ramp apparatus for detecting the presence thereon of a vehicle tire on the ramp apparatus. In addition, the monitoring system includes transmitter antenna structure and receiver antenna structure respectively embedded in the ramp apparatus. The transceiver apparatus is operable for causing the transmitter antenna structure to transmit the interrogation signal to the respective tire tags when the tire pressure sensing apparatus detects the vehicle tire. In addition, the transceiver apparatus is operable for causing the receiver antenna structure to receive the respective data modulated tire tag signals independently of one another from different tire tags. And, the transceiver apparatus is operable for demodulating the respective data modulated tire tag signals and digitizing data therefrom.
