Abstract: A method of designing a validation environment for a service implemented by an embedded electrical system. In the method one or more user requests and system responses are assigned. Next, a behavioral automata is assigned to the service, which fixes the allowed sequencing of the user requests and system responses. Then, a skeleton validation environment is automatically generated for the service. The skeleton validation environment includes testing automata produced from a traversal of the behavioral automata, a model of initial conditions, models of user requests, models of system response accuracy, an environmental model, and the dataflow and control flow assembling these models together. The skeleton validation environment covers all user requests and resultant system responses of the service. The skeleton validation environment is then recorded in a computer readable memory device for use by a design validation tool.

Abstract: Methods and systems for providing a synchronous model in a modeling environment are disclosed. The predetermined operations of the model, such as a transition to a state in a state-based modeling environment, are implicitly synchronized with a signal selected by users, such as a clock signal. The predetermined operations of the model may be synchronized on a rising and/or falling edge of the clock signal. The synchronization of the operations is guarded in which the predetermined operation of the model occurs only on the synchronization signal selected by the users while other operations may occur at any time when the model is activated.

Abstract: A method to aid designing flexible packaging for wrapping around a solid object and finalizing the packaging. The method includes accepting a description of the surface of a sheet of packaging material after wrapping around the solid object and finalizing, using a mapping of points in the 2D plane of the sheet of the packaging material to the corresponding points in the 3D surface of the wrapped and finalized packaging. The method further includes displaying the surface of the wrapped and finalized packaging or displaying graphic elements on the surface of wrapped and finalized packaging. A version includes pre-distorting graphics to correct for any distortions to graphics that occur during the wrapping and finalizing process, and generating press-ready graphics from the pre-distorted graphics for printing onto the surface of the sheet of packaging material.

Abstract: A trajectory of motion of the mechanical element is designed by using a three-dimensional curve, referred to as a three-dimensional clothoid curve, in which each of a pitch angle and a yaw angle in a tangential direction is given by a quadratic expression of a curve length or a curve length variable. A trajectory of a machine tool or a contour shape of a workpiece is expressed by using a three-dimensional curve, referred to as a three-dimensional clothoid curve, in which each of a pitch angle and a yaw angle in a tangential direction is given by a quadratic expression of a curve length or a curve length variable to control motion of the machine tool based on the three-dimensional curve.

Abstract: A CNC machine tool deflection compensation system intergrated in a CNC machine tool Controller for providing continuous, accurate, real-time compensation for unintended and/or undesired axis coordinate deflections from a preprogrammed path of tool movement in a coordinate plane, so as to ensure that the tool remains on its programmed path irrespective of such deflections capable of continuously detecting, in real-time, the presence, magnitude an rate of change of such undesired deflections and simulataneoulsy genereating instrtuctions to initiate equal and opposite deflections at the same rate of change, thereby ensuring that the tool remains on its preprogrammed path irrespective of the inherently occuring undesired deflection and/or the precipitating causes(s) thereof. The algorithms empolyed provide for automatic gouge avoidance protection and/or relocation of the tool to safe positions when necessary.

Abstract: A PWM signal on which a dither signal is superimposed is used for adjusting a central position when controlling a solenoid valve. To improve this type of control process in which the amplitude of the dither signal depends on the current of the solenoid valve and thus on the PWM signal, the PWM signal and the dither signal are generated in a computer unit independently of the power regulation process. Forming the signals separately has the advantage of generating a constant amplitude for the dither signal each time a triggering signal is generated for the solenoid valve such that the armature of the solenoid valve can oscillate specifically about the central position and thereof at constant small vibrations. This allows frictional forces to be reliably reduced and the solenoid valve to be switched more rapidly while the load on the main computer is reduced.

Abstract: A system and method for accurately measuring supply gas consumed by a particular process control component within a process control system is disclosed. Enhanced measurement accuracy is derived from measuring the consumption of the process control component in a normal operating mode of the process control system. The amount of fluid expended by one process control component is separated by a fluid control system from the amount of supply gas expended in actuating other process control components. The amount of fluid expended by each component may be determined by measuring a decrease in a fluid within a vessel having a known quantity that independently supplies supply gas to each component during its operation.

Thereafter, the present system or a further portioning system is used to cut and optionally adjust the thickness of the food product, either before or after the cutting occurs, thereby to achieve the selected end product set.
