Patent number: 6011830Abstract: The invention relates to an operational test device and a method of executing an operational test for a test system which can assume a number of operating states. A test case generator (TCG) is provided for generating a number of test cases which are sent via a test device interface (INT) to the system under test (SUT). A test state model of the test system is ascertained by a test state model generator (TSTM-G) from information on the hardware configuration of the test system (SUT), information on the possible operating states of the test system (SUT), information on the test commands necessary for bringing about changes in operating state within the test system (SUT), and from traffic values which indicate transitional probabilities ascertained in the test system's real application for the operating states. Test commands are generated on the basis of a Monte-Carlo simulation of this test state model.Type: GrantFiled: December 9, 1997Date of Patent: January 4, 2000Assignee: Telefonaktiebolaget LM EricssonInventors: Tiberius Sasin, Steffen Hermanns, Dieter Kreuer

Patent number: 4195527Abstract: The invention relates to a method of and an apparatus for producing a foam-forming reaction mixture of at least two liquid components which react together and which are fed continuously to a mixing zone where they are mixed together. The volumetric flow of at least one component is measured continuously both in the main pipe leading to the mixhead and also in a subsidiary pipe which branches off the main feed line between the storage for the components and its pump. This subsidiary stream serves as a source for intermittent weighing of the component so that the density of the reaction component can be periodically calculated and monitored. This helps ensure the proper mass of component entering the mixhead.An apparatus is disclosed which achieves precise dosing of the components so that a product free of defects and having the desired properties may be produced.Type: GrantFiled: May 17, 1978Date of Patent: April 1, 1980Assignee: Bayer AktiengesellschaftInventors: Wilfried Ebeling, Klaus Schulte, Dieter Kreuer
