Abstract
The respective wheels of a vehicle have transducers (11, 12) associated therewith which provide pulse trains (S1, S2) upon revolution of the wheels, the pulses being either 'mark' pulses if the transducer senses 'correct pressure', or 'space' pulses if the transducer senses 'low pressure'. The pulses from all the transducers are logically combined in a NOR-gate (23), and the output is connected via a common junction (J) to the count or shift inputs of a group of shift registers (22). The shift registers are individually reset by the pulses from the individual transducers. Thus, if one of the transducers signals 'low pressure' conditions, the particular shift register (22) will not be reset, and, upon shifting through to its terminal count, will provide respective output signals to individually connected indicators (27). All the indicators are connected to a common, particularly acoustic warning signal indicator (19), and a test timing circuit (T, 31) is provided, enabled upon turning ON the main switch of the vehicle to provide a test cycle and a test warning output.
