Abstract: In one example, a proxy server acts as a gateway to a website and modifies the traffic between a web browser on a user device and the website server, as necessary to request protection by providing step-up authentication and/or transaction verification. The proxy server blocks transactions when protection is required but has not occurred (either because the authentication was not proper or due to the detection of another problem). Associated methods and systems are also provided.

Abstract: Overvoltage protection circuits include a combination of an overvoltage detection circuit and a voltage clamping circuit that inhibits sustained overvoltage conditions. An overvoltage detection circuit can include first and second terminals electrically coupled to first and second power supply signal lines, respectively. This overvoltage detection circuit may be configured to generate a clamp activation signal (CAS) in response to detecting an excessive overvoltage between the first and second power supply signal lines. This CAS is provided to an input of the voltage clamping circuit, which is electrically coupled to the first power supply signal line and configured to sink current from the first power supply signal line in response to the CAS. The voltage clamping circuit may be configured to turn on and sink current from the first power supply signal line in-sync with a transition of the CAS from a first logic state to a second logic state.

Abstract: A method for entering data into at least a first and a second control device of a motor vehicle is provided. Each of the first and the second control device is provided with a sequencing control that has a reversible deactivation state, a programming mode, and an operating mode with operating functions. The first and the second control device are each put into the deactivation state, during which the execution of operating functions of the operating mode is prevented, preferably at least to a large extent. The first and the second control device are each put into the programming mode, during which the reversible deactivation state of each control device is maintained. The deactivation state of all control devices will be canceled after the respective data have been entered into all control devices in the programming mode.

Abstract: Process and winding machine for winding a continuous material web on a reel spool forming a wound reel. The process includes, upon attaining a desired roll diameter in an old wound reel, closing a new winding nip between a reeling drum and a new reel spool brought into a standby position. In this regard, the reeling drum and the old wound reel are jointly displaced while maintaining the old winding nip formed between the reeling drum and the old wound reel. After the closing of the new winding nip between the reeling drum and the new reel spool, the linear load in the new winding nip is adjusted, controlled or regulated by a corresponding displacement and tightening of the reeling drum.
