  • Patent number: 9626457
    Abstract: Method for real time computation of the state variables of a hybrid differential-algebraic process model (DAP) in succeeding time steps on a process computer with a process interface, the process computer detecting at least one process variable of a physical process and/or producing output for influencing the physical process, the hybrid DAP being solved at least by a integrator functionality, a condition evaluation functionality and identification of a condition change by a consistency detection functionality for structure decision variables, and depending on the result parts of the hybrid DAP being active or inactive. Prompt computation is possible when a condition of the hybrid DAP changes by the consistency detection functionality being carried out in a sorted consistency handling function (KHF), in the case of a condition change, first and third parts of the sorted KHF being carried out once and a second part thereof being carried out repeatedly.

  • Patent number: 9239893
    Abstract: A method for computation of the state variables of a hybrid differential-algebraic process model in succeeding time steps on a process computer with a process interface, the process computer being set up such that, via the process interface, at least one process variable of a physical process can be detected by the process computer and/or one output for influencing the physical process can be output by the process computer. In a computation process, a current mode of the hybrid DAP is determined by evaluating the state variables for a deviation of the current mode of the hybrid DAP from the mode of the hybrid DAP applying beforehand, a mode-specific process model which corresponds to the current mode being chosen from the group of executable mode-specific process models and further computation is based on it. At least one probable future mode of the hybrid DAP is determined in a prediction process.

  • Publication number: 20150069690
    Abstract: At least one adjusting element aligns a first surface of a test body, comprising a dentine and/or enamel surface, plane-parallel with respect to a contact surface and/or to at least one second surface, which is optionally coated with an adhesive dental material. The at least one adjusting element in a device is usable to produce an adhesive bond at the contact surface between the first surface and the at least one second surface. A method determines necessary force to be applied to separate or break the adhesive bond at the force surface and/or contact surface between the first and the at least one second surface.
