Abstract: Embodiments are provided for updating a playlist that has been added to a playback queue in response to changes to the playback queue. The playback queue may be associated with a zone of a network media system such that items in the playback queue are to be rendered by the zone. The playlist may include one or more items playable by the zone, and may be stored separately from where the playback queue is maintained. Embodiments are also provided for updating a playback queue in response to modifications to a playlist included in the playback queue.

Abstract: A data management platform may group a first instance of a set of virtual machines into a backup group for performing a backup of data from a source data storage environment to a target data storage environment in accordance with a backup configuration. The data management platform may receive, from a user, an input to create a second instance of the set of virtual machines at the target data storage environment. In some examples, data backed up to the target data storage environment from the first instance may be configured as a source for the second instance. The data management platform may instantiate, in response to receiving the input, the second instance of the set of virtual machines using the backup configuration for the first instance of the set of virtual machines and the data backed up to the target data storage environment.

Abstract: A multimedia controller for controlling and displaying zones in a multi-zone system is provided. In one example the controller provides a user interface for multiple zones of a media playback system comprising multiple playback devices. The controller identifies respective states associated with each zone of the multiple zones and detects an input to display a list of the multiple zones. In response to detecting the input, the controller determines an order of the multiple zones within the list of the multiple zones and displays, via the user interface, the list of the multiple zones, wherein the list of the multiple zones identifies each zone of the multiple zones in the determined order.

Abstract: To reduce power consumption, a user equipment (UE) may trigger a microsleep in a subframe when a physical downlink control channel (PDCCH) does not include a downlink grant. However, because the microsleep depends on the PDCCH not including a downlink grant, the UE cannot trigger the microsleep until after the PDCCH is decoded. Accordingly, in some aspects, a UE may enable an aggressive extra microsleep in which a microsleep duration may be increased by reducing a PDCCH decode time. For example, a UE may use a stale channel estimate and noise estimate from a previous subframe to perform PDCCH demapping when conditions related to a PDCCH block error rate are satisfied. In this way, removing channel estimation and noise estimation from a PDCCH demapping path may reduce the PDCCH decode time, whereby the UE may trigger a microsleep sooner to increase a sleep ratio and thereby increase power savings.

Abstract: Embodiments are provided for querying a media server for media content based on user-selected metadata associated with first media while the first media is being experienced by a user. In one embodiment, at least one metadata associated with the first media may be displayed for the user to review while the first media is being experienced by the user. The user may then select a displayed metadata to initiate a search for media content based on the selected metadata. The search for media content may be performed by querying a media server associated with a selection of media content services. The user may then review the results of the media query, select media content from the results, and initiate further action, such as adding the media content to a digital repository, or purchasing the media content.

Abstract: An example playback device is configured to play back a first media item and, while playing back the first media item, receive a voice command to enter a preview mode in which the playback device plays back one or more second media items for a predetermined duration that is shorter than a total duration of the one or more second media items. Responsive to receiving the voice command, the playback device enters the preview mode, thereby (i) suspending playback of the first media item and (ii) initiating playback of the one or more second media items for the predetermined duration. The playback device subsequently terminates the preview mode, thereby (i) terminating playback of the one or more second media items, and (ii) resuming playback of the first media item.

Abstract: Techniques for using ferroelectric liquid crystals Dammann grating (FLCDG) for light detection and ranging devices are disclosed. In LiDAR devices, accuracy, response time, and cost performance can be limited by some factors, such as laser pulse width, time resolution of a time-to-digital conversion chip, detector bandwidth, shot noise, and time error generated by electronic circuits. A FLCDG-based architecture can improve a LiDAR device, and provide for one-shot capturing due to the high switching speed at very low driving voltage provided by ferroelectric liquid crystals and the equal diffracting ability of Dammann grating.
