Three channel pulse power system for underwater acoustic source
Bibliographic record
Abstract
A three channel pulsed power system has been developed at the US Navy Coastal Systems Station in Panama City, Florida to provide power for underwater acoustic sources. In the present configuration, the system is capable of providing continuous operation at repetition rates up to 15 Hz and with energies up to 1.5 kJ per pulse per channel into a broad range of loads including spark-type underwater acoustic sources. The system includes three independent banks each of which contain two switcher-type power supplies, each capable of an energy output of 8 kJ/s at 3.2 kV. A highly flexible control system allows the construction of pulse trains with arbitrary trigger timings for each bank. High power silicon controlled rectifiers (SCRs) are used to form the pulse trains. The system is currently located on the deck of a remote controlled QST-35A US Navy target drone boat and provides power for three underwater spark gap acoustic sources (sparkers). The system was recently demonstrated at an Advanced Concept Technology Demonstration (ACTD) military exercise in Newfoundland, Canada.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
