The present disclosure provides systems and methods for scaling performance of Ethernet Ring Protection Protocol. Specifically, the systems and methods may apply to G.8032 and may provide protection switching control plane performance scaling benefits. In an exemplary embodiment, the present invention summarizes the per “virtual” ring control plane protocol into a single logical ring control plane protocol. Advantageously, the present invention transforms the G.8032 protocol from a per-virtual ring protocol to a per-logical ring control protocol. The mechanism/methodology that is used is to include minimal per-virtual ring instance information in to the Ring Automated Protection Switching (R-APS) (control) frames. Additionally, the present invention cleanly decouples the placement of the R-APS (control) channel block location on the ring from that of the virtual channel data blocks. Current G.8032 specifications tightly couple the location of each R-APS (control) channel block and the virtual channel block that it is managing.

An ultrasonic motor includes a stator. The stator includes a seat and a driving unit. The driving unit includes a generally semi-elliptical driving mechanism formed integrally with the seat, and two spaced-apart piezoelectric actuators disposed between the seat and the driving mechanism. Each of the piezoelectric actuators has a first end abutting against the driving mechanism, and a second end opposite to the first end and abutting against the seat.

A housing includes a substrate and a nano-composite layer deposited on the substrate. The nano-composite layer includes a number of metal oxide nitride layers and a number of Ce layers. Each metal oxide nitride layer alternates with a Ce layer, and the outermost nano-composite layer is a metal oxide nitride layer. The metal in the metal oxide nitride layer aluminum, titanium, silicon, chromium, or zirconium.

The invention provides a solution for transforming a flow graph model to a structured flow language model. In particular, the nodes in the flow graph model are traversed, and each node is mapped to an activity in the structured flow language model. When a node comprises a branch point, the corresponding branch region is identified and mapped. This process is repeated until all nodes in the flow graph model have been mapped to corresponding activities in the structured flow language model. In this manner, the desired nesting and containment relationships can be identified and generated in the structured flow language model.

The present invention discloses a method for validating user equipment, a device identity register and an access control system. Wherein the method for validating user equipment comprises: setting a central device identity register shared by different networks, wherein illegal user equipment identities are stored in the central device identity register; the central device identity register receiving an ID validation request from a mobility management entity, wherein the ID validation request carries ID parameters of a user equipment; the central device identity register validating the validity of the user equipment according to the ID parameters, and returning a validation result to the mobility management entity. In virtue of the present invention, the accessing of the illegal non-3GPP network user equipment which is capable of accessing 3GPP network to the 3GPP network is able to be controlled.

Children chair having a height adjusting device and a folding device completes folding up by height adjusting. A first leg frame of the children chair includes a first upper leg and a first lower leg capable moving relatively. When operating the height adjusting device to adjust the first upper leg relative to the first lower leg, an actuator on the first upper leg pushes a slider of the folding device, which locates at the pivot of the first leg frame and a second leg frame. The slider then interferes with a coupler locating at the second leg frame to disengage from a base mounted on the first leg frame. The second leg frame is then rotatable relative to the first leg frame and may be folded to a folding position. The children chair is easy to perform height adjustment and folding movement by simply operating a button at the handle.
