Tyre condition indicating apparatus
First Claim
1. Tyre condition indicating apparatus, adapted to be carried by a vehicle, comprising:
- an indicator; and
indicator control means connected with the indicator and operable, in dependence upon information relating to tyre condition, to change the indicator between a first state, in which the indicator is deactivated constantly, and a second state, in which the indicator is activated constantly, and a third state in which the indicator is activated intermittently;
characterised in that in the said third state a rate of intermittent activation of the indicator is dependent on the value of a tyre-condition sensing parameter included in said information.

Abstract
Tyre condition sensing apparatus carried by a vehicle has a relay module (4) in the vicinity of a vehicle wheel. The relay module (4) detects a tyre condition of a tyre in the vehicle such as tyre pressure. Tyre condition indicating apparatus carried by the vehicle has a display module (5) at the vehicle dashboard, and a sounder module (50) arranged in the vicinity of the wheel. The sounder module (50) gives audio indications audible at the wheel corresponding to visual or audio indications given at the dashboard by the display module (5). The indications are permanently off for a normal condition, permanently on for an above-normal condition and intermittently on for a below-normal condition.
