Benefits of technology

The technical effect of this patented technology allows for better understanding on how well it protects against lighting strikes by comparing different voltages and levels used during construction or repairing new lightsuits based upon their impact resistance properties. This helps identify which parts are more likely to have been damaged due to current conditions than others.

Problems solved by technology

The technical problem addressed by this patented method relates to improving the ability of transmitting electrical signals from one location (called source) to another without causing damage or malfunctions during their passage through airborne environments like rainwater. This requires consideration with factors like design features, environmental conditions, equipment used, etc., along orderly ways to determine how well these protective devices perform under specific circumstances while also considering potential impacts caused by weldings or other events happening around them.
