Abstract
A method for controlling a touchless lavatory is disclosed herein. The method includes collecting, by a processor, sensor data from a sensor, the sensor data including an ambient light measurement and an indication of motion, aggregating, by the processor, the collected sensor data for a time window, extracting, by the processor, features from the aggregated sensor data, and determining, by the processor, a probability of an activity occurring based on the extracted features. The method further includes activating, by the processor, a motor based on the determining that the activity has a high probability of occurring.
Claims15
A method of controlling a touchless lavatory, comprising:
- collecting, by a processor, sensor data from a set of sensors, the sensor data including an ambient light measurement, proximity information, and an indication of motion;
- aggregating, by the processor, the collected sensor data for a time window;
- extracting, by the processor, features for the time window from the aggregated sensor data;
- determining, by the processor, a probability of an activity of a user occurring based on the extracted features;
- and
- activating, by the processor, a motor based on the determining that the probability exceeds a threshold, the motor being configured to control a component of the touchless lavatory,
- wherein the determining the probability of the activity of the user occurring includes using at least one pretrained classification model to determine the probability of the activity, and
- wherein the at least one pretrained classification model includes a first pretrained classification model to determine an occupancy status based on the aggregated sensor data and the extracted features, a second pretrained classification model to determine a sitting status based on the aggregated sensor data and the extracted features, and a third pretrained classification model to determine a gesture status based on the aggregated sensor data and the extracted features.

A method of controlling a touchless lavatory, comprising:
- receiving, by a processor, a triggering event;
- collecting, by a processor, sensor data from a set of sensors, the sensor data including an ambient light measurement, proximity information, and an indication of motion;
