Position correction method of osteotomy guide tool and orthopedic surgical system
A method for correcting position of an osteotomy guide tool and an orthopedic operation system are disclosed. A trackable element mounted on the osteotomy guide tool or on the robotic arm tracks the position of the osteotomy guide tool and generates position information of the trackable element. According to the current position and the desired position of the trackable element, a robotic arm drives the osteotomy guide tool and the trackable element to move, until the trackable element is moved to the desired position. This method does not need to consider the absolute position accuracy of the robotic arm, and does not rely on the experience of the surgeon. The tool has several guiding features, which can provide guides for osteotomy operations, so that the same osteotomy guide tool can perform multiple operations of osteotomy and punching, thus greatly reducing the operation time and improving the operation efficiency. |

Handling of multi-access PDU session when inter-system change
A method of handling multi-access (MA) Protocol data unit (PDU) session under inter-system change is proposed. An MA PDU session uses one 3GPP access network or one non-3GPP access network at a time, or simultaneously one 3GPP access network and one non-3GPP access network. The UE and network can support Access Traffic Steering Switching and Splitting (ATSSS) functionalities to distribute traffic over 3GPP access and non-3GPP access for the established MA PDU session. Upon intersystem change from 5GS to EPS over the 3GPP access, if interworking with EPS is not supported, the MA PDU session is maintained in 5GS over the non-3GPP access type. Data traffic over of the MA PDU session over the 3GPP access type is transferred to the non-3GPP access type. |

Hybrid proxying with user space hold
Certain features and aspects provide a proxy for a node in a cloud computing cluster that holds the packet used by a remote client to initiate a connection until a backend server is ready. When the user space controller receives the packet, it notifies the server that a connection is being established and holds the packet until the proxy receives a notification that the server is ready. The user space controller of the proxy then writes routing information to memory so that kernel space is used for the connection traffic going forward, and reinjects the packet into the networking layer of the cluster. Subsequent packets, including any acknowledgement packet that is part of the initial handshake, will flow through kernel space without involvement of the user space controller and be processed more efficiently than would be possible using user space. |

Optoelectronic component with current deflected to high-gain paths comprising a three-terminal avalanche photodiode having an insulating layer between absorbing region and a leakage path
A three-terminal avalanche photodiode provides a first controllable voltage drop across a light absorbing region and a second, independently controllable, voltage drop across a photocurrent amplifying region.
