  • Publication number: 20240057806
    Abstract: A machine with a grinder, a grind chute for delivering coffee grounds along a flow path and into a portafilter fitted to the machine, and a tamping unit with a tamping mechanism for pressing the coffee grounds held by the portafilter into a puck, wherein the tamping mechanism includes a linkage connected to a tamp, the linkage being arranged to press a face of the tamp in an axial direction with respect of the portafilter during a tamping operation, and wherein the linkage returns the tamp to a rest position where the tamp face is moved laterally, out of the flow path. The invention also relates to a machine for delivering coffee grounds to a portafilter, a tamping mechanism and a coffee grinding machine.

  • Publication number: 20240057808
    Abstract: A tamp including a body and a tamping face carried by a base of the tamp, the base and body being arranged for relative movement in an axial direction during a tamping operation to compress and expand under action of a bias element, wherein the tamp includes a rotation mechanism to translate the relative axial movement of the base and body into rotational movement of the base. The invention also relates to a portafilter holder for positioning a portafilter under a tamping unit of a coffee grinding machine, for receipt of the coffee grounds, the portafilter holder including a dock to receive the portafilter and a retention member to hold the portafilter in the dock.

  • Publication number: 20240048744
    Abstract: Aspects of the disclosure include methods, apparatuses, and non-transitory computer-readable storage mediums for video encoding/decoding. An apparatus includes processing circuitry that decodes prediction information of a current block in a current picture that is a part of a coded video bitstream. The prediction information indicates a non-directional intra prediction mode for the current block. The processing circuitry partitions the current block into a plurality of partitions. The plurality of partitions includes at least one L-shaped partition. The processing circuitry reconstructs one of the plurality of partitions based on at least one of (i) neighboring reconstructed samples of the one of the plurality of partitions or (ii) neighboring reconstructed samples of the current block.

  • Publication number: 20230221186
    Abstract: A method of operating a milk frothing device that includes at least one processor operatively associated with one or more actuators. The method is performed by the at least one processor and includes calculating a number of the actuators activated by way of contact with an underside of a vessel, determining a presence or an orientation of the vessel based on the calculated number of the activated actuators, and controlling an operation mode of the milk frothing device based on the determined presence or orientation of the vessel.
