Kiyoku is the blanket name for a series of technologies originally developed for use in mech cockpit systems. The technology was later adapted for a variety of venues and functions, and led to the development of ISITS.
The first generation of the Kiyoku technology was brought back by Hunter Jusenkyou during the story Tsubasa Kiyoku from The Inclination to Destiny. The equipment was installed in a mobile suit sharing the name of the story, which he stole shortly after destroying his school-issued suit. The basis of the technology was using a machine called a Mind Stream Generator to transmit tactical information from the sensor array directly into the pilot's brain.
Initial Production Cycle
The development cycle of Kiyoku went through a series of stages before being dramatically re-worked.
The basic form of the technology, called merely 'kiyoku', used a total of 12 Mind Stream Generators and was simply linked to the various flight data colectors. The existing display screens offered a dizzying array of information, which when fed directly into the pilot's mind was overwhelming.
The re-designed version of the technology built by Hunter's team, used Gudersnipe parts and regulations. 12 Mind Stream devices were reduced to two, placed in a helmet with the generators at the base of the skull. The rest of the helm included a series of Electro-Encephalo-Graphic probes which monitors pilot brain activity, and adjusted the information stream accordingly. Further, the data was drawn from a single source: the GS-built Combat Scanner. While the scanner added more parameters than the flight data collectors originally used, it had the data better organized. Additionally, the scanner had an algorithm that calculated data importance at high speed, delivering the information by order of relevence.
Kiyoku Blue was still overwhelming, and could only be used by a handful of pilots. Through extensive testing, the Eighth Power identified a crucial EEG spike that allowed them to determine who was "positive" for the system, and who could not use it without risking brain damage.
Basically a sub-variant of Blue, Light could exclude parameters from the system. Any of the 455 parameters the combat scanner feeds out by default could be excluded from the stream. Testing revealed that the average pilot could interpret about 15 parameters without intolerable mental strain.
A severly stripped down variant of Light, offering the pilot only one parameter, contact tracking, was tested for use by Crimson Blade atmospheric combat pilots. This was the only type of Kiyoku Technology to see use outside of Gudersnipe School.
Red added a new twist to the system: in addition to the mind-stream generator, it brought in a nueral interpretation control system. The concept was to plant a scanner on the back of the pilot's neck (externally; no implants) to read the signals traveling along the brain stem. The idea was to increase reaction time by removing the pilot's need to move.
The concept is as follows: normally, to manipulate a control, your brain tells your arm to move, then your arm tells your brain that it did. Fair enough, the interpretation system was able to read the information, specifically the commands, carry out the desired control manipulation, then route a signal through the mind stream generator, all in a fraction of the time it would take the pilot to do it himself.
Kiyoku Red caused massive bio-chemical imbalances in the human body. The new system interfeared with the human body's ability to regulate itself, causing temperature spikes and gland secretions which could poison a pilot from the inside. Several test pilots nearly died, and a bio-regulation system had to be developed to prevent the imbalance.
Set to be the final production model, Gold incorporated the bio-regulation system directly into the cockpit, along with all the advancements of Red. However, the high-profile on-campus suicide of Massey Ruyov revealed a critical flaw in the Gold system and the entire project was immediately mothballed.
Prisim was the name given to the version of Kiyoku used in Kiyoku Gold.
Almost as soon as the original program was shelved, the development team opened a whole new project, dramatically re-imagining the purpose of function of Kiyoku. The new system was called Intuitive Synaptic Interpretation and Translation System (ISITS), and encorporated Kiyoku Light as part of a larger system. ISITS would go on to be so succesful that it would be used by the Victory Research Facility as part of the Dynasty Project and numerous other VRF programs.
The final single-cockpit form of the technology, Ascendancy used ISITS along with a more advanced combat scanner coupled to a relational database. It was by far the most powerful version, but in many ways more dangerous than Gold. It succeeded where the original initiation of Kiyoku failed: it allowed the pilot to see into the future.
