Ferrofluid-assisted micro rotary motor for minimally invasive endoscopy applications
Bibliographic record
Abstract
This paper reports a micro rotary motor that is enabled with magnetic fluid called ferrofluid used as an extremely simple, miniaturized bearing material for microendoscopy applications. The ferrofluid bearing is magnetically sustained on the permanent magnet rotor that is levitated by the bearing layer inside a tubular substrate, an endoscope catheter. The levitated rotor is electromagnetically driven by two photo-defined meander-type coils formed around the outer walls of the catheter that enables 90°-step angular actuation of the rotor. The fabricated prototype with the rotor coupled with a 1-mm-sized prism mirror is revealed to provide both step-wise and continuous rotations with revolution rates up to 1875 rpm, verifying the effectiveness of the bearing and motor mechanism. The prototype device is operated to demonstrate its ability of endoscopic imaging in an experimental model.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
