Abstract: Embodiments of the present disclosure provide systems and/or methods for managing power distribution over a USB topology. In some embodiments, a host device is coupled to an upstream facing port device (UFP device) via a USB compliant connection, and a USB device is coupled to a downstream facing port device (DFP device) via a USB compliant connection. The UFP device and DFP device are connected via a non-USB compliant extension medium. In various embodiments, the UFP device and DFP device may be individually powered by different types of sources (such as external power sources, power distributed over the extension medium, batteries, USB bus power, and/or the like). The UFP device and DFP device cooperate to provide USB power distribution functionality throughout the USB topology despite the presence of the non-USB compliant extension medium.

Abstract: A method for replicating a structure of a biological tissue provides a plastically deformable film that is subjected to a pressure in order to press it into a mold. The mold comprises formations for pit-like depressions, recesses and notches. The recesses each border on at least one of the pit-like depressions and are opened up. The notches form at least one film hinge in the film. The shaped film is folded into a stack having at least two layers of film, the film hinge forming the folding edge for the folding process. The pit-like depressions are closed along their direction of extension by a neighboring layer of the stack and form each time a capillary. At least two of the opened recesses are arranged one on top of another and form a canal arranged perpendicular to the plane of extension of the film.

Abstract: Boardroom table systems are provided that include a plurality of USB Type-C receptacles that can provide power and/or data transfer functionality to one or more devices attached thereto. Power transferred by the boardroom table system may be managed by USB Power Delivery, and may come from a source of wall power, or from a device coupled to one of the USB Type-C receptacles. Data transferred by the boardroom table system may include USB data, Ethernet data, video data, and/or any other type of data transmittable via a USB Type-C receptacle. In some embodiments, boardroom table systems also include presentation devices. In such embodiments, a device coupled to a USB Type-C receptacle could both transmit or receive power, exchange data, and transmit video to the presentation device via the same USB Type-C receptacle of the boardroom table system, thus eliminating the need for multiple sockets and cables.

Abstract: In some embodiments, the present disclosure provides techniques for reducing an amount of bandwidth used for the communication of DisplayPort information via a USB Type-C receptacle. In some embodiments, this reduction in bandwidth allows for the concurrent exchange of USB 2.0 information, SuperSpeed information, and four lanes of DisplayPort information via a single USB Type-C receptacle. In some embodiments, this may be accomplished in part by processing the information from the four DisplayPort lanes to be transmittable via two differential pairs of the USB Type-C connection, thereby providing four lanes of DisplayPort communication over the USB Type-C connection concurrently with SuperSpeed information. In some embodiments, the reduction in bandwidth of the DisplayPort information may be used for other purposes, such as transmitting high bandwidth DisplayPort information over a cable or connector of a low quality that would otherwise not support such an exchange.

Abstract: In some embodiments, the present disclosure provides techniques for concurrently exchanging USB 2.0 information, SuperSpeed information, and four lanes of DisplayPort information via a single USB Type-C connection. In some embodiments, this may be accomplished in part by multiplexing signals such as the USB 2.0 signals and the DisplayPort AUX signal to fewer than a standard number of conductors in order to free up other conductors for the third and fourth lanes of DisplayPort information. In some embodiments, a standard USB Type-C receptacle, plug, and cable are used. In some embodiments, a modified receptacle, plug, and/or cable are provided.

Abstract: Methods and devices for transmitting SuperSpeed information between a host device and a USB device via an extension medium are provided. Link partner relationships are established between the host device and an upstream facing port device, between the USB device and a downstream facing port device, and between the upstream facing port device and the downstream facing port device. While the link partner relationship between the upstream facing port device and the downstream facing port device is substantially compliant to the USB 3.0 Specification, the link partner relationship may use a configurable link layer acknowledgement timer to compensate for delays in transmission over the extension medium.

Abstract: An apparatus and method for access point groupings bridging tunneled traffic for a communication network, includes a first step of associating each access point with a location parameter. A next step includes grouping access points in accordance with the location parameter. A next step includes receiving a packet.

Abstract: Devices, systems, and methods for selectively pairing an upstream facing USB port device (UFP device) and a downstream facing USB port device (DFP device) over a network are disclosed. A controller device sends pairing commands to a selected UFP device and a selected DFP device, which then establish a connection with each other over a network. The controller device may subsequently cause the UFP device and/or the DFP device to remove the existing pairing and to instead pair with a different UFP device or DFP device. A pairing between a UFP device and a DFP device allows a host device coupled to the UFP device and a USB device coupled to the DFP device to communicate via a USB-compatible protocol.

Abstract: A system and method for multicast video streaming over a wireless local area network (WLAN) improves scalability and reliability. The method includes configuring the WLAN access point with a reserved video bandwidth (step 1005). A multicast video stream including data packets marked with differentiated services code points (DSCPs) is then received (step 1010). The multicast video stream is then converted to a plurality of “n” unicast streams (step 1015). Data packets in the unicast streams are then streamed from the WLAN access point to a plurality of “n” mobile units using a selective packet discard algorithm that employs the DSCPs (step 1020).

Abstract: Transactional memory compatibility type attributes are associated with intermediate language code to specify, for example, that intermediate language code must be run within a transaction, or must not be run within a transaction, or may be run within a transaction. Attributes are automatically produced while generating intermediate language code from annotated source code. Default rules also generate attributes. Tools use attributes to statically or dynamically check for incompatibility between intermediate language code and a transactional memory implementation.

Abstract: System(s) and method(s) facilitate improved performance for insert/update query requests in a database. A lazy updating based on delaying updates of newly inserted records combined with a master-staging partitioning scheme avoid deterioration of performance arising from updating indexes related to new records inserted in a database. Table partitioning as well as partitioning of indexes associated with the table allow new records to reside in manageable sections of memory for pre-configured periods of times prior to being updated. To avoid deterioration of performance associated with increasing size of table/index partitions, the size is maintained below specific thresholds that can be determined based on query workload and other historical data. Deployment of partitions among file systems and design of update delay times can further increase performance of lazy updating.
