Abstract: In some implementations a system can be configured to reduce the burden of pairing user devices with playback devices. For example, all users (or user devices) who commonly operate within a particular environment (e.g., a home) can be configured as authorized users of playback devices within the particular environment. When one of the authorized users pairs a user device with a playback device, all of the user devices for all authorized users can be automatically paired with the playback device as a result of the single pairing. Thus, only a single authorized user is burdened with the pairing process in order to pair all authorized users with the playback device.

Abstract: A golf club head having a slot in the sole filled with an insert in which the slot is positioned close to the striking face. The slot can be a uniform distance from the striking face or the slot can curve away from the striking face in the toe region. The insert can have a uniform height or a non-uniform height. Inserts with uniform heights can have a low height profile. Inserts with non-uniform heights can have a lower height in a central portion of the insert compared to an edge portion or a perimeter portion of the insert. The insert can also have flanges or protrusions for installation into the slot. The resulting golf club head improves performance, as the sole slot with insert allows the striking face to have a profile that meets the needs at that location.

Abstract: The invention discloses a dynamic intensity-modulated segmentation method for an orthogonal double-layer grating blade device. The core of the segmentation algorithm is to construct a virtual single-layer grating after the velocities of the two-layer gratings are synthesized to perform dynamic intensity modulation of the single-layer grating (sliding-window) segmentation, and finally use two layers of gratings to conform to each segment.
