TIRE PRESSURE MONITORING SYSTEM FOR MOTORCYCLES
First Claim
1. A tire pressure monitoring system comprising:
- a valve-stem mounted tire pressure gauge, said gauge comprising;
a first processor;
a pressure sensor, in communication with said first processor, for detecting a tire pressure;
a wake circuit adapted to periodically activate said first processor to receive an output of said pressure sensor, said output indicative of a tire pressure detected by said pressure sensor;
a memory, accessible to said first processor, for storing a value indicative of a tire pressure detected by said pressure sensor; and
a first radio frequency module, in communication with said first processor, for emitting a wireless signal indicative of a tire pressure detected by said pressure sensor;
an externally powerable remote display unit, said unit comprising;
a second processor;
a second radio frequency module in communication with said second processor, said second module configured to wirelessly communicate with said first radio frequency module; and
a display, in communication with said second processor, for displaying at least a graphical indicator indicative of the tire pressure detected by said pressure sensor.

Abstract
A tire pressure monitoring system for a motorcycle includes a tire valve stem mounted tire pressure gauge and an externally powerable remote display unit. The pressure gauge includes a pressure sensor, a wake circuit, a processor, and a first radio frequency (RF) module. The remote display unit includes a second RF module and a display. The wake circuit is adapted to activate the processor periodically at a predetermined interval of time and causes the processor to receive an output signal from the pressure sensor. The output of the pressure sensor is indicative of a tire pressure detected by the pressure sensor. The remote display unit is adapted to display the measured tire pressure value without any user input.

15. A method of monitoring tire pressure for a motorcycle comprising the steps of:
-
periodically activating a processor in a valve-stem mounted tire pressure gauge to receive an output of a pressure sensor in said tire pressure gauge, said output indicative of a tire pressure detected by said pressure sensor; causing, by said processor, a first radio frequency module in said tire pressure gauge to emit a wireless signal, said wireless signal indicative of a tire pressure detected by said pressure sensor; receiving, at a second radio frequency module in an externally powerable remote display unit, said wireless signal emitted by said first radio frequency module; and displaying, in said remote display unit, a graphical indicator representative of a value of the tire pressure detected by said pressure sensor. - View Dependent Claims (16, 17, 18)
