The approach of complex insert packaging fabrication in stereolithography is studied in the paper. There are many difficulties being overcome, such as the dispensing shadowing problem caused by the geometric shape of insert, the polymer feeding problem caused by greater insert height than the layer thickness, and the positioning problem of insert that leads to instability of packaging. These drawbacks led to unsatisfactory results of the insert packaging in stereolithography. In order to solve the problems, a new method of complex inserts packaging fabrication and its associated algorithm in stereolithography is proposed in this paper. Based on the geometric information, function and assembly direction of the inserts, the packaging approach is developed. The approach proposed in this paper has been verified by experiments. It brings considerable contributions to the application of insert packaging in stereolithography. It is also favorable to the improvement of insert packaging efficiency and assembly fabrication.

Automatic defect inspection systems are becoming more and more important in industrial production lines. Especially in electronics industry, an attempt is often made to achieve almost 100% quality control of all components and final goods. Here we are interested in the defect inspection of color filter, which is one of components in TFT-LCD module and gives each pixel of LCD its own color. The difficulties in the defect inspection of color filter are its complex texture and demand for high-speed processing. In this paper, we propose a neural-fuzzy-inference-network (NFIN)-based defect inspection algorithm to detect the materials with regular pattern such as color filter. The NFIN, which is basically a fuzzy inference system and its fuzzy rules and corresponding parameters can be learned by neural network automatically, is a good alternative to achieve the defect inspection. Experimental results show that the proposed algorithm is a promising method to detect the defects of color filter. The proposed algorithm can apply to not only the detection of color filter but also the detection of web materials.

A miniaturized rotational precision positioning stage using the spring-mounted piezoelectric actuators is proposed in this paper. The positioning stage features micro/nano-meter order moving ability that is caused by piezoelectric (PZT) impact force, and continuous actuation ability with unlimited rotational displacement that is obtained by the integration of compression spring and PZT actuator. A one-DOF (degree-of-freedom) experimental setup consisting of two spring-mounted PZT actuators was configured to examine the motion characteristics of the positioning stage. The main experimental results were obtained as follows: the rotational step motion was recorded as 12times10-6 rad due to one single actuation by pulse driving waveform having an amplitude of 70 V, and the continuous rotational step motion was obtained with an average value of 12times10-6 rad due to 10 times of actuations. Furthermore, the motion behaviors were examined by varying the amplitude of applied voltage. The average step motions due to 10 times of actuations were recorded as 38times10-6 rad and 1.5times10-6 rad, respectively, when the corresponding actuating amplitudes were 100 V and 50 V. The proposed stage having precision rotational ability and self-moving ability was experimentally demonstrated.

A multivariable multi-objective approach has been presented for the design of servo controller for a dual-stage actuator system. The designed control algorithm instructs the two actuators to cooperate towards a faster track seeking and better disturbance rejection than any actuator acting alone. Cooperation is explicitly formulated as control objectives and the optimal control algorithm is designed using the H2 control theory and regulator theory. Each actuator's involvement in the cooperation can be further adjusted by changing the design weighting coefficients, while the design procedure guarantees the stability of the control system.

A method of plasma beam treatment providing liquid crystal (LC) aligning substrates of improved alignment stability is described. In this method the aligning substrates are obliquely treated with a plasma flux containing alignment and passivation agents simultaneously. This method is applicable for the substrates of organic and inorganic origin. During this treating process, good pretilt angle stability and alignment quality are much promised.

In this work, the inverse kinematics of sixteen fundamental 6-DOF robot manipulators with offset wrist were solved analytically and numerically. Analytical and numerical techniques are the most common approaches for solving inverse kinematics problems. They are generally desired to be solved analytically in order to have complete solution and fast computation. This approach is also called as closed form solution and in the absence of it, numerical techniques are used for solving the inverse kinematics problem. As examples, the inverse kinematics solutions of RS (Scara robot), CS (cylindrical robot), and NN (spherical robot) robot manipulators with offset wrist were presented in this paper. Also, the inverse kinematics solution techniques for sixteen fundamental robot manipulators equipped with offset wrist were summarized in a table.

The research of micro aerial vehicles (MAVs) is a new field of low-Reynolds-number flow, which attracts much attention in the advanced aeronautical area. The flapping wing, proved by many natural flyers, is the most appropriate way of flying objects which sizes are less than 6 inches. However, there is still plenty of room for studying on the unsteady aerodynamic characteristics of flapping wings. The flapping wing, which is light weighted and high strengthened, is originally composed of the titanium-alloy frame and the parylene skin. Such an integration of fabrication needs the help of MEMS processing. Additionally, the flapping test after the wing fabrication and the corresponding signal analysis from the smart wing skin concluded this project and set the bases for the wind-tunnel verification/correction in the very near future.

This paper develops the flight path angle control for the glide-slope tracking via backstepping design. A candidate controller structure for an aircraft glide-slope tracking is presented. Using the backstepping procedure to synthesize a glide-slope tracking control law is different from designing the guidance and control loops separately in autopilot. The derived glide-slope control law is much simpler and easier to construct with localizer controller. Nonlinear 6DOF simulation results demonstrate that the backstepping tracking law can effectively guide the aircraft along the glide-slope centerline until the flare control before touchdown.

The developed system has integrated network technology, a CNC machine, an engraver, a robot, a conveyor and an on-line CCD camera forming a remote machining cell. The JAVA programming language was adopted in enabling the developed remote machining cell to be a platform independent system; and CORBA (common object request broker architecture) technology was used to bridge the integration with control devices. Users can use this system to learn to operate remote facilities such as feeding a work piece and machining the work piece via the distributed Internet. The remote machining cell can also be online monitored through networked CCD video connection. This system can be used to enhance the CNC, FMC, and CIM courses for undergraduate students and is expected to integrate with virtual reality technology for future network-centric and information technology enhanced digital lecturing systems.

Impedance or admittance characteristic must be measured by a spectrum analyzer for piezoceramics in order to gain the electromechanical match at resonance frequency before piezoceramic actuating applications. A virtual analyzer is implemented with an acquisition card inserted into a personal computer and with the LabVIEW tools developed in Windows. While the voltage inputted onto the piezoceramics and the current sampling simultaneously, thus, the instantaneous admittance level relative to frequencies is furnished in the functional screen. The measured results from the virtual analyzer and actual data through a HP-4194A analyzer are compared to validate the performance of the virtual instrument.
