Title: Network optimisation method
Inventor: LIZ SCOTT JAMES
IPC: H04L29/08
Filed: 2018-08-31
Abstract: A control system determines transit time, within a time sensitive network, of an Ethernet frame having a given frame format. The system comprises one or more controllers (20, fig. 3) and is configured to receive data related to the frame format, 30, including frame destination, and data relating to the network. The system uses a regression algorithm to determine a predicted transit time for the frame, 32, and an associated error value, based on the frame format and network data. The frame format data may include tag control information (TCI) such as a priority code point (PCP), a Drop Eligible Indicator (DEI) and a VLAN identifier (VID). The algorithm may include linear regression, long short-term memory (LSTM) or autoregressive integrated moving average (ARIMA) algorithms, or an artificial neural network. The control system may further determine an optimised PCP parameter value for optimising the transit time of the Ethernet frame, 36, in dependence on a quality of service (QoS) requirement of the frame. The method may be associated with the IEEE 802.1Q networking standard. The control system may be used for critical systems in a vehicle (50, fig. 5).

Title: An end effector for a surgical instrument
Inventor: JAMES DICKSON
IPC: A61B17/295
Filed: 2019-03-19
Abstract: The end effector comprises a pair of pivotally connected 104 jaw members (100, 102, fig 1) each having a flange 106, 108 with an elongate slot 110, 112 and a drive assembly having a drive pin 22 and a drive shaft 24.
