Abstract
A material coating system for an apparatus having a housing configured to contain a fluid is disclosed herein. A multi-layer coating is applied to the housing to mitigate damage caused by external factors. The multi-layer coating includes: a layer of a primer coating having anti-corrosive properties, a layer of a mid coating having mechanical and chemical properties capable of at least partially closing a hole in the housing to avoid fluid leakage and optionally a layer of a top coating having properties that resist ultraviolet radiation from passing therethrough.
Claims23
-35. (canceled)
A system for detecting an object approaching and/or impacting electrical equipment, the system comprising:
- a housing for the electrical equipment;
- at least one acoustic sensor for measuring a sound pressure of the object approaching the housing, the at least one acoustic sensor disposed at a predetermined location at which the at least one acoustic sensor is not in contact with the housing;
- at least one vibration sensor for measuring an acceleration of a surface of the housing caused by the object striking the housing, the at least one vibration sensor disposed at a predetermined location at which the at least one vibration sensor is in contact with the housing;
- at least one computer processor;
- and
- a non-transitory computer readable storage medium having thereon a plurality of machine-readable instructions that when executed by the at least one computer processor cause the at least one computer processor to determine at least one of approach of the object for impact on the housing using comparisons of signal received from the at least one acoustic sensor against a threshold, and impact of the object to the housing using comparisons of signal received from the at least one vibration sensor against a threshold for the acceleration.
