Abstract
A transmitter unit has a housing adapted to be coupled in association with a trailing vehicle. The housing also has a multiple axis accelerometer adapted to sense the status of the transmitter unit and a trailing vehicle. The housing also has electronic components coupled with the accelerometer. A receiver unit has a housing adapted to be coupled in association with a leading vehicle. A user in audio proximity to the receiver unit is wirelessly signaled in the event of an anomaly at the transmitter unit.

19. A monitor system comprising:
-
a transmitter unit having a housing adapted to be coupled in association with a trailing vehicle, the housing also having a three axis accelerometer, the monitoring being with respect to a first axis for monitoring up and down movement, a second axis for monitoring side-to-side sway movement, and a third axis for monitoring forward and rearward movement, the housing also adapted to sense the transmitter unit and a trailing vehicle, the housing also having electronic components coupled with the accelerometer; and a receiver unit having a housing adapted to be coupled in association with a leading vehicle to wirelessly signal a user in audio proximity to the receiver unit of any anomaly at the transmitter unit; wherein the receiver also has an accelerometer to measure at least one axis and to compare information it takes from what it receives from the transmitter in a trailing vehicle to null out the road conditions and then looks for additional movement at the transmitter to indicate problems.
