Abstract: A high-speed connector includes an insulating body and a terminal module. The terminal module includes a number of terminal groups. Each terminal group includes a number of ground terminals, a number of signal terminals and two shielding pieces. The ground terminal includes a ground pin. The signal terminal includes a signal pin. Each shielding piece includes a number of convex portions and a number of surrounding portions. The ground pins and the signal pins are distributed in a staggered manner. At least one ground pin is in contact with the convex portions of the two shielding pieces. The surrounding portion surrounds the signal pins. When the ground pins and the signal pins are no longer in the same plane or the same row, the shielding piece can prevent cross-talk among signals, thereby improving the transmission quality.

Abstract: Embodiments of the present disclosure provide a protective apparatus for an indirect access memory controller. The apparatus can include: a bus monitoring unit configured to monitor a bus address and detect an operation type of a bus accessing the indirect access memory controller, update a corresponding window register if the operation type is a window register operation, initiate permission authentication if the operation type is a register controlling operation, and perform list entry configuration if the operation type is a permission list configuration operation; a window register unit configured to store operation addresses of different access types; a permission list unit configured to partition a memory space into several virtual memory protection areas, and independently set a access permission attribute for each memory area; and an unauthorized operation processing unit configured to process a subsequent operation performed when a permission violating access occurs.

Abstract: A tibial prosthesis and a knee prosthesis are provided. The tibial prosthesis includes a tibial plateau, a first tibial insert and a second tibial insert. The tibial plateau has a proximal end face defining a mount surface arranged with respect to a first axis. The first tibial insert is disposed on the mount surface rotatably about the first axis. The first tibial insert has a first concave surface centered on the first axis. The first concave surface is distally recessed. The second tibial insert is disposed on the tibial plateau and has a second concave surface extending along an arc-shaped trajectory line that is parallel to the mount surface. The arc-shaped trajectory line is centered on the first axis, and the second concave surface is distally recessed. The first tibial insert and the second tibial insert are arranged independently of each other, and the first tibial insert is located medially to the second tibial insert.
