Abstract: A holder for an elongate aerosol-generating device defining a longitudinal axis is provided, including: a cover and defining a docking space to accommodate the device, the cover being moveable between a covering position, in which the cover covers at least a portion of the docking space, and a non-covering position, and when the cover is in the covering position, a first portion of the cover defines a first curve, and when the cover is in the non-covering position, the first portion of the cover defines a second curve, a radius of curvature of the second curve being greater than a radius of curvature of the first curve, and when the device is accommodated in the docking space and the cover is in the covering position, the device is enclosed by the holder so as to be completely surrounded by the holder and the first curve curves around the longitudinal axis.

Abstract: A holder for an aerosol-generating device is provided, the holder including: a docking arrangement to engage with the device and including a docking space defined between a first end and an opposing second end spaced from and fixed relative to the first end, the docking space accommodating a longitudinal dimension of the device; and a retainer to engage with an end of the device to releasably retain the device in the docking space, the retainer having a first surface fixed relative to the first end, and a second surface projecting away from the first end into the docking space, the second surface being deflectable relative to the first end on engagement with the end of the device, the second surface includes a resiliently deformable elastic or elastomeric material, which includes a nitrile, and resilient deformation of the material allows the second surface to be deflectable relative to the first end.

Abstract: A network server includes a communicator connected to a network; and at least one processor configured to communicate, through the communicator, with a user terminal connected to the network. The processor is configured to include or associate content IDs, determined according to one or more requests from the user terminal, in or with a playlist, the content IDs corresponding to content files, respectively, stored in a database; reflect actions of the user terminal, associated with one or more of the content files, on log data sets corresponding to the content IDs; and determine one or more of the content IDs as one or more target IDs to be selectively deleted or excluded from the playlist, on the basis of the log data sets.
