Abstract: The present invention is related to the prevention of intrusions on an in-vehicle network.

Abstract: A key generation device for a vehicle-internal communication system and a method for the vehicle-internal management of cryptographic keys comprises providing at least one secret for a vehicle-internal key generation device and generation of at least one new cryptographic key by the vehicle-internal key generation device on the basis of the at least one secret. The generation and providing of the at least one new cryptographic key takes place autonomously and is triggered by a key-exchange event, or a combination of key-exchange events. The key-exchange event may be one of a vehicle-internal change, an environmental change and a security key.

Abstract: A method of monitoring execution of computer instructions includes receiving data items representing real-time measurements of side-channel information emanating from execution of computer instructions, each data item forming a value of a corresponding dimension of a side-channel information vector, receiving, for two or more of the dimensions of the side-channel vector, classifiers that assign the corresponding values of a side-channel vector to classes, and classifying the data items in accordance with the received classifiers, wherein an orthogonal distance of the data item from the classifier indicates a confidence value of the classification, generating a combined a confidence value for the side-channel information vector a, and outputting a signal if a confidence value indicates affiliation to a selected one of the two classes with a predetermined probability. The method conducts a self-test by generating a combined confidence value based to ensure correct outputting of the confidence value.

Abstract: To produce fertilizer, a system and method concentrates manure slurry in a mechanical vapor recompression evaporator (“MVR”) having a heat exchanger. The MVR receives the manure slurry within a first side to evaporate ammonia laden-water vapor from the slurry, leaving a nutrient concentrate. A compressor raises the evaporated ammonia-laden water vapor to a higher energy state. Within a second side of the heat exchanger, the compressed water vapor conveys heat to the slurry. Ammonia-laden water condenses in the second side at a process temperature to be conveyed to an ammonia stripping tower where the ammonia-laden water is dispersed into ammonia-laden water droplets. In the tower, a flow of air is directed across a surface of the ammonia-laden water droplets, the process temperature having been selected to promote the escape of ammonia gas from the ammonia-laden water droplets, the flow of air provided to entrain ammonia gas in the flow.

Abstract: A system and method for reclaiming nutrients from dairy manure includes a centrifuge for separating a liquid fraction of the manure from a solid fraction comprising organic material; a mechanical vapor recompression evaporator (“MVR”) to receive the liquid fraction from the centrifuge and evaporating the liquid fraction by mechanical vapor recompression to produce ammonia-laden water vapor and a concentrated nutrient slurry; a dryer for drying the nutrient slurry to a selected moisture content to be available as an ingredient in compounded fertilizer; and an ammonia stripping tower assembly to receive ammonia-laden water vapor from the MVR and from it to precipitate ammonium sulphate salt and condense water as separate products.

Abstract: A cap assembly for use with multiple bottles having different size necks is provided. The assembly includes a base, at least one adapter and a lid. The base includes a compartment for storing the adapter and an opening having at least two internally threaded sections of different size and a port. The adapter includes an internally threaded opening having at least two sections of different size and an externally threaded surface having at least two sections of different size. The lid is mounted on the base for movement between a position wherein the base opening port is closed and a position wherein the base opening port is open. Additional adapters may be included. The additional adapters are configured to accept bottle necks of different sizes than the base opening and first adapter such that at least six bottles with different size necks can be used with the assembly.
