The present invention relates to a consumable recognition system for recognizing placement and/or type of consumable containing a food substance for the preparation of a beverage by use of a beverage dispenser. To enable the recognition of placement and/or type of consumable in a simple, foolproof and easily implementable way an embodiment of the system comprises a light source (31, 301, 311, 321, 331, 341) for emitting light (35) to the consumable (4a, 40, 50, 60, 70, 80, 90), a light sensor (32 302, 312, 322, 332, 342) for sensing light (36) reflected from a reflection element (42, 52, 63, 73, 83, 93) of the consumable to obtain a sensor signal, wherein the sensor signal depends on the position, orientation, fluorescence, phosphorescence and/or polarization characteristic of said reflection element, and a signal processor (33) for recognizing placement and/or type of consumable based on said sensor signal. |

1. Consumable recognition system for recognizing placement and/or type of consumable containing a food substance for the preparation of a beverage by use of a beverage dispenser, the system comprising:
a consumable for use in a beverage dispenser for preparation of a beverage comprising a filtering body defining a space containing a food substance from which the beverage is obtained; the consumable further comprising a reflection element for reflecting incident light in a predetermined way, wherein the way depends on the position, orientation, fluorescence, phosphorescence and/or polarization characteristics of said reflection element, a light source for emitting light to the consumable, a light sensor for sensing light reflected from a reflection element of the consumable to obtain a sensor signal, wherein the sensor signal depends on the position, orientation, fluorescence, phosphorescence and/or polarization characteristic of said reflection element, and a signal processor for recognizing placement and/or type of consumable based on said sensor signal. |
