Abstract: A method of adapting tuning parameter settings of a system (2) functionality (3) for road vehicle (1) speed adjustment control starting from initially selected settings and applying a training set of speed adjustment profiles obtained from manually negotiated road segments and road segment data for these. For each of these road segments: —a simulated speed adjustment profile is calculated using the selected settings and the road segment data; —the manual and the simulated speed adjustment profiles are compared to obtain a residual; —a norm of the residual is calculated. For all of the road segments of the training set: —a norm of the norms of the residuals is calculated; —at least one of optimization, regression analysis or machine-learning is performed to minimize the norm of the norms of the residuals by selecting different settings and iterating the above steps. Settings rendering a minimal training set norm are selected.

Abstract: A method of curve speed adjustment for a road vehicle includes obtaining data on: current ego velocity; distance and curvature of an upcoming road segment, represented by a set of control points to be negotiated; road property of a road comprising the road segment; environmental properties; and driver properties. The obtained data is continuously streamed to a data processing arrangement arranged to perform a translation to target velocities for the respective control points and, for each respective control point, a translation from target velocity for that control point and distance to that control point and obtained current ego velocity, to a target acceleration to reach that control point at its target velocity. The resulting target accelerations are continuously streamed to a control unit of the road vehicle to adjust the road vehicle acceleration to reach each respective control point at its target velocity.

Abstract: The present disclosure relates to a method for controlling an autonomous driving configuration or driving assistance configuration comprising at least two adjustable parameters. The method includes, at an electronic device with a display, displaying on the display a user interface. The user interface includes a graphical representation of a current setting of the at least two adjustable parameters associated with the autonomous driving configuration or driving assistance configuration. The method further includes detecting via one or more input devices, a user input directed towards a first adjustable parameter of the at least two adjustable parameters, and updating the graphical representation on the display based on the detected user input. More specifically, the updating of the graphical representation is done by modifying the current setting of the first parameter of the at least two adjustable parameters and modifying at least one characteristic of a second adjustable parameter.

Abstract: A load balancer dynamically load balances packets for network connections between clients and servers. When receiving a packet from a client that requests a new connection, the load balancer checks the current load of all the servers and selects the server most suitable to handle the new connection. The load balancer then forwards that packet to the selected server. If the server accepts the request for the new connection, then the server responds with an acknowledgement packet. The acknowledgement packet also includes the server's blade identification that the client uses for all subsequent packets on the accepted connection. When the load balancer receives a packet containing the blade identification, the load balancer forwards the packet to the server corresponding to the blade identification. Backup load balancers can therefore continue packet forwarding services in a smooth and efficient manner.

Abstract: A method and system for protecting software products from unauthorized use and distribution is described. The system comprises a client process executed on a client computer coupled to a producer computer over a network. The method comprises the steps of providing to a user a copy of the distributed software, the distributed software comprising an incomplete executable program requiring a security module to be installed prior to execution on the client computer. The user receives a registration code for use with the distributed software. Upon attempted execution of the distributed software the producer computer requests user registration from the user. Upon receipt of the registration information including the registration code from the user, the producer computer validates the registration code and constructing a security module for transmission to the client computer. The security module is integrated with the distributed software to allow execution of the executable program.
