Cybernetic helmet

A cybernetic helmet was a type of technology used aboard Federation Starfleet starships in the 2260s. The helmet amplified a person's thoughts.

History
When the USS Enterprise (NCC-1701) explored a subspace parallel universe, a cybernetic helmet proved invaluable. Some of the laws of nature acted differently, resulting in a loss of energy to power cells and dilithium crystals. Spock theorized that, in this region, thoughts could be strong enough to manipulate objects. While wearing a cybernetic helmet, Lieutenant was able to pilot a repair pod. While holding hands with other crew on the bridge, she was able to maneuver the Enterprise, not only to avoid an attack by another vessel but also to return the starship to the prime universe.
