1. A vehicle comprising:
- an operative sub-system positioned within an internal portion of the vehicle; and
a sensor assembly secured to the operative sub-system, wherein the sensor assembly includes;
(a) at least one sensor configured to detect vibration or shock energy directed into the operative sub-system, wherein the at least one sensor is configured to generate an electrical signal in response to the vibration or shock energy; and
(b) a processing unit configured to determine damage to the operative sub-system as damage data that is based on one or both of a magnitude and duration of the vibration or shock energy detected by the at least one sensor, wherein the processing unit is powered through the electrical signal, and wherein the processing unit analyzes the electrical signal that is used to power the processing unit to determine the damage data.

Abstract
A vehicle may include an operative sub-system positioned within a body of the vehicle, and a sensor assembly secured to the operative sub-system. The sensor assembly may include at least one sensor configured to detect vibration or shock energy, directed into the operative sub-system; and a processing unit configured to determine damage to the operative sub-system as damage data that is based on one or both of a magnitude and duration of the vibration or shock energy detected by the sensor(s). The sensor assembly may be self-powered.
