US Patent 11361011 Sensor-related improvements to automatic replenishment devices

The disclosed techniques relate to improving sensor data collection/reporting at an automatic replenishment device (ARD). For example, sensor data associated with the item stored at an ARD may be collected. The ARD can calculate a change in the amount of the item stored by the ARD from the sensor data. If the change is over a reporting threshold, the sensor data (or the amount of change) may be transmitted to a back-end system. Reporting may not occur if additional sensor data (e.g., accelerometer data and/or images captured at the ARD) is not commensurate with a user interaction. If the difference is under the reporting threshold or unlikely due to user interaction, the ARD may refrain from transmitting the sensor data. These techniques conserves power at the ARD, relieves the back-end system from needless processing, and enables more accurate indications of the amount of the item stored by the ARD.
