A Dual-Purpose Microwave-Optical Component for Wireless Capsule Endoscopy: A Feasibility Study by Radio Link Analysis
Bibliographic record
Abstract
Wireless capsule endoscopy (WCE) is the only option for non-invasive small intestine disease diagnostics. However, the small size of the capsules poses a major design challenge for engineers since multiple optical and electrical components must reside inside the capsules. This article proposes a space-saving dual-purpose component utilized in both optical image capturing and microwave wireless data transmission of a WCE capsule at the 915 MHz industrial-scientific-medical band. The optical performance is verified through ray-tracing simulations, whereas the microwave operation is demonstrated by full-wave impedance simulations and by conducting a radio link simulation and measurement with an up-scaled prototype. The results show that the proposed component can be utilized in capsule optics to achieve an acceptable imaging quality. Furthermore, the component operates as an antenna, providing adequate link gains for WCE wireless communications.

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.
