Abstract: A method for providing a deterministic behavior in a shared physical network is disclosed. The method may be performed in a device controlling a Virtual Local Area Network, VLAN, of the shared physical network. The method includes rate limiting amount of inbound traffic for each traffic flow in the VLAN and assigning a respective priority for each traffic flow in the VLAN.

Abstract: The present invention relates to a method and a device of measuring the interaction between a driver and a vehicle in use to decide the security coefficient for vehicles and/or for drivers, and an instrument showing said safety coefficients. The invention is characterised in that a measuring/registering and maybe calculating parasite system (16) is connected to the steering system (12) of the vehicle for a registering measurement of the signal activity (19) between driver (14) and vehicle (18), that implementing a known measuring impulse in the steering system in the ordinary noise during the manoeuvring of the vehicle, whereby the response from the driver on said measuring impulse will be registered by the parasite system (16) which also compare the difference between an induced impulse and the response pulse from the driver and presents said difference on a graphic display unit, as a characteristic sound, or store it in a memory device.

Abstract: The method and apparatus relates to a procedure and an arrangement for minimizing the risk of the undesired escape of water from pipe systems and units connected thereto in premises and similar surroundings by the use of a control or valve arrangement arranged at the point of connection of the pipe system to the external supply pipe and capable of regulation by means of an adjuster device. A link is provided between the valve arrangement and the device for detecting the presence or movement of individuals inside the premises, and the operation is such that, in the event of the detection of presence or movement, the valve is kept open so as to permit water to enter the pipe system or network, whereas the valve is kept closed in the absence of such detection.
