Tire condition monitoring apparatus
First Claim
1. A tire condition monitoring apparatus for monitoring the condition of a tire attached to a vehicle, comprising:
- a transmitter, wherein the transmitter is driven by a battery for detecting the condition of the tire and wirelessly transmitting a signal including condition data that indicates the detected tire condition; and
a receiver, wherein the receiver receives the signal transmitted by the transmitter and processes the received signal;
wherein;
the signal transmitted by the transmitter includes synchronous data, which is provided at the beginning of the transmitted signal;
the data included in the transmitted signal other than the synchronous data are each configured by a binary code signal; and
the synchronous data is configured by a specific signal that has a pattern different from the binary code signal.

Abstract
Different types of data included in a signal transmitted by a transmitter, except for synchronous data, are each configured by a binary code signal of a predetermined bit count. The synchronous data is configured by a signal of a pattern different from the bit codes that configure the data other than the synchronous data. This enables a receiver to recognize the synchronous data in the transmitted signal easily and reliably. Further, the data length of the synchronous data is shortened. This shortens the data length of the signal, thus ensuring optimal wireless communication between the transmitter and the receiver.
