Automated Olfactory Detection System for Sequential Sample Analysis

The system segments the presentation of multiple samples by using a mechanical conveyor that delivers samples sequentially through a single aperture, one at a time. This segmentation in time allows precise tracking of which sample the animal is responding to, while still achieving high throughput through automated continuous presentation. The aperture acts as a gate that isolates the animal's olfactory input to a single sample source at any moment.

A mechanical intermediary system (conveyor with aperture) is introduced between the multiple samples and the animal. This intermediary controls the timing and delivery of samples, ensuring that only one sample reaches the animal at a time while maintaining a queue of multiple samples ready for presentation. The intermediary resolves the contradiction by decoupling the plurality of samples from the singularity of the animal's sensory input.

The system enables self-service detection by automatically recording and interpreting the animal's responses without human intervention. Sensors detect the animal's behavior (such as nose movements or position changes) and automatically log which samples triggered responses. The system self-evaluates detection accuracy by comparing against known positive and negative samples, eliminating the need for human handlers to interpret responses while maintaining high measurement precision.

The patent replaces the mechanical system of human observation and interpretation with electronic sensing and automated data processing. Sensors substitute for human eyes and brains in detecting and interpreting animal responses. This substitution eliminates human subjectivity and fatigue-related errors while maintaining system simplicity through automated workflows that require minimal human input.

The system dynamically adapts the sample presentation configuration based on the operational phase. During training, the conveyor presents samples sequentially through the single aperture in a controlled manner suitable for learning. During testing, the same single aperture receives samples from a high-speed conveyor that can present multiple samples rapidly. The dynamic flexibility of the system allows the same enclosure to serve both training and testing functions efficiently, eliminating the need for multiple enclosures.

The single-hole enclosure with integrated conveyor system serves multiple functions: it can be used for both training and testing phases, and the same aperture handles both simple training samples and high-speed test samples. The conveyor system itself is universal, capable of adjusting presentation speed and sample flow based on whether the animal is being trained or tested. This multi-functionality eliminates the need for separate enclosures for training and testing.

The system implements real-time feedback by continuously calculating sensitivity (percentage of correct positive detections) and selectivity (percentage of correct negative detections) as samples are presented and animal responses are recorded. These metrics are displayed immediately, allowing operators to monitor animal performance during both training and testing phases. The feedback loop enables real-time adjustment of training protocols or testing parameters to optimize detection performance.

The patent replaces manual calculation and evaluation methods with automated electronic computation. A computer system automatically tracks animal responses, identifies which samples were positive or negative, and calculates sensitivity and selectivity metrics in real-time. This substitution of mechanical calculation with electronic processing achieves high measurement precision while managing complexity through software automation rather than complex hardware.
