Claim 0:
1. A tire sensor device for monitoring a condition of a tire, the tire sensor device comprising:
a plurality of sensors including a temperature sensor and a three-axis accelerometer having a first predetermined axis, wherein said first predetermined axis of said accelerometer is installed in a direction aligned with a circumference of a tire such that said accelerometer of the tire sensor device is aligned along a known axis with respect to the tire;
memory configured to store data received by the plurality of sensors;
a microprocessor coupled with the memory, the microprocessor configured to perform one or more initial processing operations on the data received by the plurality of sensors, the one or more initial processing operations including determining one or more tire characteristics using data from the plurality of sensors acquired at a frequency greater than a frequency of rotation of the tire; and
an antenna, coupled with the microprocessor, configured to wirelessly communicate with one or more external devices;
wherein the tire sensor device has dimensions less than 5 cm×5 cm×2 cm; and
wherein the one or more initial processing operations include determining, using data from the accelerometer relating to the periodic motion of the tire along an axis of rotation of the tire, and then analyzing motion of the tire as determined by said data from the accelerometer to determine a wheel misalignment.
