Actuator Control

In order to rapidly develop the control system of the Electromechanical Actuator (EMA), the DSP development platform is established using rapid prototyping method based on the MATLAB software, and all the models is configured and researched. First, the DSP development platform structure in the environment of MATLAB is mainly presented. And the operation principle has been showed. Then, the EMA control circuit board schematic diagram is necessarily introduced, which one is for the developer to conveniently configure the system model. Finally, the developer reasonably configures the control system models used in the Simulink library and constitutes them to speed closed loop control system of the EMA. The EMA control system code will be compiled and debugged rapidly through this platform. The executed program will automatically download into the DSP processor. And the result of debugging would be sent to the CAN bus receiver. For generally speaking, the difficulty of EMA control system code development method is reduced and the development cycle is shortened using this rapid prototyping method. And this system development method is fast and effective.

System Generation

A technology for rapid prototyping expert systems or intelligent systems as a whole is proposed. The main constituents of the technology are the object-oriented model of data and knowledge representation and the mechanism for data-knowledge transformation on the basis of an effective algorithm of inferring all good classification tests. An approach to expert system development by means of this technology is analyzed. The toolkits for expert system generation are described and the application of these tools to the development of a small geological expert system is demonstrated.

Femtosecond laser micromachining (FLM) is a fairly new and novel technology for 3-D processing of engineering materials without the constraints associated with traditional micromachining based on Si technologies. FLM has shown great promise in rapidly fabricating components at a microscale and that it can also be used to machine on an array of engineering materials both metals and non-metals for variety of applications. This work presents the development of a FLM environment equivalent to a 3 DOF CNC machine with the laser beam acting as the machine tool. The environment includes a Ti:Sapphire laser (800 nm wavelength and 120 fs pulsewidth), various optics for beam guidance and power control and three mutually perpendicular motorized stages (8 in travel with 0.05 μm resolution of motion and capable of executing industry standard G-codes). A postprocessor for generating the G-codes using CAD/CAM software is successfully customized. Subsequently, the results of an ablation study for common engineering materials and its usage in defining machining parameters for rapid prototyping of various thermal actuators will be presented along with examples of microcomponent fabrication.

Summary Objectives: Healthcare processes typically generate an enormous volume of patient information. This information largely represents unexploited knowledge, since current hospital operational systems (e.g., HIS, RIS) are not suitable for knowledge exploitation. Data warehousing provides an attractive method for solving these problems, but the process is very complicated. This study presents a novel strategy for effectively implementing a healthcare data warehouse. Methods: This study adopted the rapid prototyping (RP) method, which involves intensive interactions. System developers and users were closely linked throughout the life cycle of the system development. The presence of iterative RP loops meant that the system requirements were increasingly integrated and problems were gradually solved, such that the prototype system evolved into the final operational system. Results: The results were analyzed by monitoring the series of iterative RP loops. First a definite workflow for ensuring data completeness was established, taking a patient-oriented viewpoint when collecting the data. Subsequently the system architecture was determined for data retrieval, storage, and manipulation. This architecture also clarifies the relationships among the novel system and legacy systems. Finally, a graphic user interface for data presentation was implemented. Conclusions: Our results clearly demonstrate the potential for adopting an RP strategy in the successful establishment of a healthcare data warehouse. The strategy can be modified and expanded to provide new services or support new application domains. The design patterns and modular architecture used in the framework will be useful in solving problems in different healthcare domains.

Musculoskeletal conditions are a major health concern in United States because of a large aging population and increased occurrence of sport-related injuries. The need for bone substitutes is especially important. Traditional treatments of bone-defect have many of limitations. Bone tissue engineering may offer a less painful alternative to traditional bone grafts with lower risk of infection. This research integrates biomimetic modeling, solid freeform fabrication (SFF), systems and control, and tissue engineering in one intelligent system for structured, highly porous biomaterials, which will be applied to bone scaffolds. Currently a new SFF-based fabrication system has been developed, which uses a pressurized extrusion to print highly biocompatible and water soluble sucrose bone scaffold porogens. To date, this system can build simple bone structures. In parallel we are utilizing a commercial rapid prototyping (RP) machine to fabricate thermoplastic porogens of various designs to determine the feasibility of injecting a highly viscous scaffold material into porogens. Materials which have been successfully used to make scaffolds by injection include calcium phosphate cement (CPC), molten poly-caprolactone (PCL), 90/10 and 80/20 (v/v %) composite of PCL and calcium phosphate (CaPO4,). Results presented for the injection method include characterization of attainable feature resolution of the RP machine, as well as preliminary cell-biomaterial interaction data demonstrating biocompatibility of CPC scaffolds. The preliminary results using a commercial rapid prototyping machine have demonstrated that the indirect porogen technique can improve 2–4 folds the resolution of SFF system in fabricating bone scaffolds. The resultant scaffolds demonstrate that the defined porous structures will be suitable for tissue engineering applications.

Thick Medium

TEM characterization and microanalysis of the recording media is crucial and complementary to new material system development as well as quality control applications. Due to the type of material generally used for supporting the medium, i.e., a polymer, conventional macro- and microthinning procedures for thin foil preparation are not applicable. Ultramicrotorny (UM) is a viable option and has been employed in previous similar studies. In this work UM has been used for preparation of XTEM samples from a magneto-optical (MO) recording medium in its original production format.The as-received material system consisted of a 4-layer, 2100 Å thick medium including a 300 Å TbFeCo layer enveloped by silicon nitride protective layers supported on a 1.2 mm thick × 135 mm (5.25 in.) diameter polycarbonate disk. Recording tracks had an approximate pitch of 1.6 μm separated by 800 Å deep peripheral grooves. Using a Buehler Isomet low-speed diamond saw, 1 mm wide and 20 mm long strips were cut out of the disk along the recording tracks.
