Abstract: Service deployment in the conventional network is very complicated. Operator needs to plan the service path in advance, and then manually configure the policy for each node on the service path. The software-definable network service configuration method disclosed in the present invention is different from the conventional network. On the one hand, the control layer has a global network resource view to more easily plan service paths for service requests. On the other hand, the control layer adopts a centralized management of physical switch nodes in the data layer via a southbound interface, which makes it easier to automatically implement policy configuration in physical switch nodes.

Abstract: Methods for assembling low-profile, singulated keyboards by prefabricating key assemblies onto a chassis strip that is divided into individual key assemblies only after the substrate is affixed to a feature plate of keyboard. For example, a row of key assemblies is fabricated onto a chassis strip. The row corresponds to a partial or complete row of keys of the keyboard. The chassis strip is thereafter affixed to a feature plate in a specific location, thereby aligning each prefabricated key assembly to a precise location on the feature plate. While connected, each prefabricated key assembly is independently affixed to the feature plate. Thereafter, interconnecting portions of the chassis strip between the prefabricated key assemblies are removed, thereby singulating each key assembly.

Abstract: An electronic device such as a speaker device may have a curved housing characterized by a vertical longitudinal axis. A layer of fabric may cover the curved housing. A touch sensor may be used to detect touch input on the layer of fabric. The touch sensor may include capacitive touch sensor electrodes including drive lines and sense lines. In some arrangements, the touch sensor is formed from conductive strands in the layer of fabric. In other arrangements, the touch sensor is formed from conductive traces on a substrate. The substrate may be formed from portions of the curved housing or may be formed from a layer that is separate from the housing. Light-emitting components and/or fabric with different visual characteristics may be used to mark where the touch-sensitive regions of the fabric are located. The touch-sensitive regions may be shaped as media control symbols.
