  • Patent number: 7203552
    Abstract: A method, or corresponding apparatus, for controlling deformation of a structure, in part, includes applying a command signal at a first signal level to at least one actuator mechanically coupled to a structure, the first signal level known to produce an energy level in the actuator(s) substantially the same as an energy level currently stored by the actuator(s). The method enables the actuator(s) to respond to the command signal by applying an electrical reference to the actuator(s). The method drives the command signal from the first signal level to a second signal level, changing the actuator(s) in at least one dimension as a function of the command signal, which results in a corresponding deformation of the structure. The method electrically disables the actuator(s) by removing the electrical reference, which results in maintaining deformation of the structure defined by energy stored by the actuator(s).

  • Patent number: 6778863
    Abstract: The invention relates to a computer application in the field of control, monitoring, modification and/or optimization of processes which comprise real process sequences of discrete events, so-called “discrete event dynamic systems”, which cannot usually be described by systems of (differential) equations. Such processes occur for example in technical developments as well as in other business activities in the industrial or tertiary sector. Such a real process is reflected in a process model which is connected to the real process via at least one interface. If the interface(s) is/are bi-directional, real process data can be transmitted into the model directly, i.e. without data conversion, and thus the real process can be monitored; in the model, simulations can be carried out with changed process data; and finally if the result of the simulation is successful, process modifications can be transferred directly to the real process.

  • Patent number: 6344802
    Abstract: A control system is disclosed which permits information captured by each sensor to be sent exactly to a main controller and a fall in the level of sensor signals with time to be automatically compensated for with no need to make sensor signal lines long and without reducing the sensor monitoring accuracy and limiting the number of sensors used. The levels of signals from sensors connected to each of unit controllers are compared with slice levels. The results of comparisons are converted into a serial signal and then transmitted to the main controller. Each time the sensor signal level is monitored, the optimum slice level therefor is set.

  • Patent number: 6212436
    Abstract: Object services like methods or properties are provided to or inherited by objects dynamically during run-time. In one method of providing dynamic inheritance, hierarchical relationships are defined between multiple objects such that each object references or is referenced by another object. A call is made for a particular service (e.g., a method or property) at a selected object. The service is provided directly from the object whenever the service is available therefrom. Whenever the selected service is unavailable at the selected object, the call is passed to a hierarchically superior object. Another aspect of dynamic inheritance is that an object, such as the root object, may include one or more methods for adding or otherwise changing the methods or properties available from that object.

  • Patent number: 6148239
    Abstract: A process control system using feed forward control threads based on material groups performs material tracking to account and adjust for variability of processing in a process flow that includes multiple machines, machine configurations, and machine setups. The process control system using feed forward control threads based on material groups distinguishes variations in processing parameters and characteristics for processed material samples and modifies processing at subsequent steps in response to the variations. The process control system using feed forward control threads based on material groups controls materials groups so that material samples with a like processing history are processed with a similar machine configuration or setup for subsequent processing steps.
