Model Information
Description
latch-detect is a single-stage object detection model that detects the latch clips on the corners of a NICU radiant warmer hood. It uses the same MobileNetV2 + FPN + anchor-free head architecture as the companion person and patient detection models, retrained to recognize warmer latch hardware. Downstream logic infers the warmer hood state: one or more detected clips indicates the hood is closed/latched; zero detections indicates it is open/unlatched. Asymmetric hysteresis (2 consecutive open readings to open, 3 to close) is applied in the application layer for stability. This model is a development and evaluation tool produced as part of Intel's NICU Warmer reference design and has not undergone clinical validation.
Intended Use
This model is intended for use by software developers and researchers evaluating AI-assisted equipment-state monitoring in a NICU context on Intel hardware. It demonstrates detection of small mechanical features (latch clips) in warmer video as a proxy for hood-closed/open status. latch-detect itself does not provide any medical functionality, nor is it intended to process or interpret medical data for a medical purpose. Developers are responsible for independently validating and adapting latch-detect for their specific use case. It must not be used in live clinical environments or relied upon for patient-safety decisions.
