Abstract: A beverage capsule (10) for use in a beverage preparation machine to prepare a beverage by passing a fluid therethrough. The beverage capsule comprises: a cup-shaped body (12) having a base (14) and a sidewall (16); a lid (22) sealed to the cup-shaped body; and a punctured support plate (20) positioned inside the cup-shaped body and dividing the interior volume into a first compartment for holding beverage ingredients (24) and a second compartment. The punctured support plate is located at a distance from the base which is larger than a piercing height of a draining member of the beverage preparation machine. The cup-shaped body, the lid and the punctured support plate are made of a material comprising metal.

Abstract: A system, method and computer product for estimating a component of a provided audio signal. The method comprises converting the provided audio signal to an image, processing the image with a neural network trained to estimate one of vocal content and instrumental content, and storing a spectral mask output from the neural network as a result of the image being processed by the neural network. The neural network is a U-Net. The method also comprises providing the spectral mask to a client media playback device, which applies the spectral mask to a spectrogram of the provided audio signal, to provide a masked spectrogram. The media playback device also transforms the masked spectrogram to an audio signal, and plays back that audio signal via an output user interface.

Abstract: A capsule 10 for the preparation of a beverage, comprising a body 11, and a rim structure 12 having an edge 14 extending outwardly with respect to an outer surface of the body 11; and a contact element 13 which protrudes from a remaining portion of an upper surface 19 of the rim structure 12 thereby forming an annular channel 18 between the outer surface of the capsule body 11 and an inner side wall 17 of the contact element 13; the capsule being configured to cooperate with a beverage preparation apparatus and characterised in that the contact element 13 is located at a predetermined distance away from the edge 4 of the rim structure 12.
