Abstract

According to one embodiment, a beverage preparation machine (100) includes a beverage dispenser (202), a cup holding region (110) located below the beverage dispenser (202), a light source (104) configured to transmit light across a portion of the cup holding region (110), and a receiver (108) configured to receive at least a portion the light transmitted by the light source (104). A processor (240) determines whether a transparent cup (220) has been sufficiently inserted into the cup holding region (110) or is at a desired height by detecting either a trough in a light level of the portion of the light received at the receiver (108), or an inverted trough in a light level of the light transmitted by the light source (104). Upon making the determination that the transparent cup (220) is not sufficiently inserted or at the desired height, the processor (240) prevents the beverage dispenser (202) from dispensing a beverage.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 805,590, filed February 14, 2019, which is incorporated herein by reference. Background technique [0003] For high-pressure coffee machines and related beverage preparation machines, it is important to ensure that the user's cup is fully inserted into the machine placement area and at the correct distance from the beverage dispenser. However, certain challenges arise when the user's cup is made of a transparent material such as glass. There is a need for a system for accurately detecting the presence and / or height of a clear cup in a beverage preparation machine. There is also a need to detect the localization of other transparent objects. Contents of the invention [0004] In one aspect, the present disclosure may relate to a beverage preparation machine comprising a beverage dispenser; a cup holding area located below the beverage di...
