The patent application (Publication Number: US20240034609A1) describes an automated beverage dispensing attachment designed to engage with a container and deliver liquid through a fluid passage to a spout. The attachment includes a capacitive sensor that detects changes in capacitance signals to identify the start of a pour. The processing circuitry analyzes the capacitance signal over time to determine the pouring action accurately. Additionally, the attachment features a cork with a flexible exterior surface for frictional engagement with the container, enhancing the attachment mechanism.

Furthermore, the patent application details the use of capacitive inserts embedded in the cork to aid in identifying attachment to the container based on changes in capacitance signals due to relative movements. The fluid passage within the attachment is designed with a cylindrical interior surface, and the capacitive sensor surrounds a portion of it. Multiple capacitive sensors can be utilized, each associated with a unique capacitance signal, allowing for precise monitoring of the pouring process. The processing circuitry can also determine the level of the capacitance signal and identify gripping of the container based on this information, enhancing the functionality of the automated beverage dispensing attachment.
