Abstract: A system (1) for washing a 3D-printed object (4). The system (1) has a washing device (2) and a workpiece (3) that includes the 3D-printed object (4). The washing device (2) has a container (7) that forms a process chamber (8) for receiving a liquid cleaning agent (9), and the container (7) has an inlet (10) into the process chamber (8). The workpiece (3) further has a support structure (6) that supports the 3D-printed object (4) and a base (5) supporting the support structure (6).

Abstract: Techniques are described for switching streaming of media content between content delivery networks (CDNs) during mid-stream. An initial CDN can be used to stream the media content. The performance of a second CDN can be measured by requesting a fragment of the media content as a measurement or test fragment. Streaming of the media content can be switched to the second CDN if its performance is determined to be better than the initial CDN.

Abstract: Techniques are described for reducing the delay between the live playhead of live streaming content and the client playhead of a client device consuming the live stream. In one technique, an increased playback speed is used by the media player on the client device so that the delay is gradually reduced. In another technique, the media player jumps forward in the stream, skipping content identified as expendable.

Abstract: Techniques are described that enable the use of variable bit rate (VBR) encoding for live content.

Abstract: Techniques are described for adjusting parameter settings for bitrate selection algorithms for devices streaming media content. Control parameter settings are selected for playback of first media content. Test parameter settings are selected for playback of second media content. If the test parameter settings result in better playback performance relative to the control parameter settings, the test parameter settings become the new control parameter settings.

Abstract: Techniques are described for balancing traffic among content delivery networks (CDNs). A CDN balancer can analyze CDN performance data and determine CDN balancing ratios used to distribute traffic among the CDNs.

Abstract: A system for delivering live streaming content based on accurate media data fragment size and duration. The system may include a client media player to receive a portion of a streaming media file (e.g., in an MP4 format), download a first sub-portion of the streaming media file including fragment-level metadata, and parse and analyze the fragment-level metadata to determine a size and duration of a current fragment of the media file. A media server may generate custom data identifying a size and duration of a current fragment of a media file. The media server may insert the custom data (e.g., as a custom header or unique packet identifier) and send the custom data to a client media player. The client media player may be configured to decode the custom data and determine the current fragment size and duration.

Abstract: Techniques for delivering live streaming content are described by which a streaming heuristic is selected based on the delay between the live and client playheads. For live content for which the delay is short, a low latency streaming heuristic is selected which is designed to handle live content streams for which only a few seconds of content can be buffered. For live content for which the delay is longer, a higher latency streaming heuristic is selected which is designed to handle streams for which the delay is sufficient to build a buffer of content fragments.

Abstract: A hydraulic conveying device for an internal combustion engine may include a pendulum slide pump including an inner rotor drivingly connected to an outer rotor via a plurality of pendulum slides. A hydraulic actuation device may change an eccentricity between the inner rotor and the outer rotor via an actuation member. The actuation member may be prestressed by a spring device. The actuation device may further include a first pressure-setting chamber and a second pressure-setting chamber for adjusting the actuation member. At least one of the first pressure-setting chamber and the second pressure-setting chamber may be connected via a control valve to a pressure side of the pendulum slide pump. A hydraulic line may connect the pendulum slide cell pump downstream to a hydraulic medium filter. The control valve may be connected to the hydraulic line upstream of the hydraulic medium filter.

Abstract: A device for progressively building up an object from a light hardenable material. The device has a perforated build platform for the object. The build platform forms a build surface that faces a light source. The build platform and the light source are positionable relative to each other by computer control. The device is further configured for supplying the light hardenable material through the perforation of the build platform for building up the object. The invention enables the making of colored objects by stereolithography.

Many manifest files providing playback options for different time periods of a live stream of media content can be generated and provided to viewer devices. Requests from viewer devices using the manifest files can be analyzed to determine a fragment to be provided for playback in relation to the time period of the live stream to be provided for playback.

Abstract: Techniques are described for live streaming media content using on-demand manifests. A manifest file providing playback options for a portion of the duration of the playback of a live stream can be provided to viewer devices. The viewer devices can also be provided location identifiers for the live stream. Based on the location identifier used by the viewer devices to request fragments of the live stream of the media content, the requests from the viewer devices using the manifest file can be analyzed to determine a fragment to be provided for playback in relation to the time period of the live stream.

Abstract: Methods and apparatus are described for implementing a communication channel between a client device and a content distribution network (CDN) during playback of media content. The communication channel can be used by a client device to provide the CDN information pertaining to fragments the client device anticipates requesting from the CDN, as well as by the CDN to provide feedback to the client device regarding whether it is likely that the CDN will be able to satisfy the anticipated requests. The CDN can perform various operations based, at least in part, upon the information it receives from the client device.
