The shield consisted of two identical portable stations with each possessing an activation device. An input device was also included that allowed the user to alter the shields settings. To use the device, the stations needed to be placed no more than 30 miles from one another and no less than 10 miles close to each other. When activated, the shields generated an orange force field stream between the two stations in a hemispherical pattern. This shield worked to prevent the ultraviolet radiation from affecting the inhabitants of the planet.
