Wireless pulse echo interrogation of an AC electric potential resonator sensor
Bibliographic record
Abstract
In this paper, a wireless interrogation method based on pulse-echo technique is demonstrated for passive resonator based sensors. This technique can be employed for the measurement of time varying measurands. The measurand studied in this paper is a 60 Hz AC electric potential that varies the resonance frequency of a passive, resonator sensor. The resonance frequency shifts in response to applied potentials due to a varactor that is coupled to the cavity. The interrogator sends radio frequency pulses to the resonator and records the ringback received from the resonator. The wireless interrogation system is designed for the frequency range of 2400-2500 MHz in the ISM band. The pulses that contain the RF signal have a repetition frequency of 1.5 MHz for a resonator with a quality factor of 500. The maximum interrogation distance is then theoretically calculated as 15.75 m for a maximum resolution of 20 kHz corresponding to a potential shift of 100 mV.

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.
