Abstract
A receiver assembly (16) includes an amplitude shift keyed mode (52) and a frequency shift keyed mode (58) selectively engagable to receive radio frequency transmissions from the tire monitoring system (26) and a remote keyless entry system (20) and switches between modes in response to receipt of a wake up pattern.
Claims19
A receiver assembly for receiving signals from different devices with differing signal formats comprising;
- a first mode for receiving a first signal;
- and
- a second mode to receive a second signal of a different format than said first signal, said first mode engaged to receive signals in a default condition, said second mode engaged to receiver signals in response to a wake up pattern.
A method of receiving signals of different formats from different systems comprising the steps of;
- a. receiving a first signal in a first mode;
- b. receiving a second signal in a second mode, said second signal differing from said first signal and including a wake up pattern;
- c. switching between said first and second modes in response to receipt of said wake up pattern.
