Abstract: A vehicle monitoring system includes a controller and one or more vibration sensors that measure operational frequencies of different vehicle components during operation of the vehicle. The controller receives the measured operational frequencies and compares them to modeled frequencies for one or more operational states of each of the different vehicle components. The controller determines that the operational frequencies in a particular frequency range associated with a specific component correspond to an abnormal operational state for that specific component in response to the operational frequencies in the particular frequency range deviating from the modeled frequencies for a normal operational state of the specific component or matching the modeled frequencies for the abnormal operational state of the specific component. The controller generates and presents the abnormal operational state of the specific component on one or more of a vehicle console or a user device.

Abstract: A method and apparatus for controlling the total load presented to an AC power source such as a generator or inverter used to provide backup or portable power. The frequency of the output AC power is controlled in response to the loading on the power source, thereby providing information about that loading of the power source which is carried by the AC power itself, thus reducing or eliminating the need for traditional wired and wireless communications. By controlling the frequency of AC power, controllable loads and load control devices can determine the amount of remaining power available from the power source in order to determine if a given load can be connected without creating an overload. The frequency may also be controlled at the power source to indicate an overload, with the loads being responsive to that overload frequency to reduce the load and thereby alleviate the overload.
