In this paper we use an embedded system to design and implement an arbitrary waveform generator. Its modules are a touch panel and the DAC interfaces. The user draws arbitrary design waveforms on the touch panel. The embedded system then draws a straight line between two points using the Bresenham line algorithm which is like a piecewise linear method. After recording the information of the waveform, the embedded arbitrary waveform generator outputs the signal when the user touches ldquoRunrdquo. In addition, the embedded arbitrary waveform generator also provides the basic waveform output, adjustment frequency and voltage. The basic waveform includes sine, triangle and square waveforms. The DAC interface that we have designed includes data buffer, DAC and crystal and amplifier. The embedded system sends the data of the waveform to the data buffer when the user touches ldquoRunrdquo, then sends the control signal to read the digital data and to the DAC conversion. Currently this design outputs for one channel. We can extend that to more than two channels if we increase the DAC interface of the same structure. Then our design can adjust the frequency of the crystal and the capacity of the data buffer to raise the output frequency. Raising the frequency of the crystal raises the output frequency. Raising the capacity of the data buffer provides a wider range of output frequency.

To expand the scope of humanspsila perception on satellite-roadway-vehicle network, roadway images in encountered scene are matched with birdpsilas eye view. Based on the geometric consistency of the satellite images with as-is local terrain, in this paper, a computational mechanism is presented for generation and adaptation of roadway model transferable through the network. Laplacian-Gaussian filter is applied to the distribution of random texture in the scene image for generating a fractal model of the perspective of the roadway area. The structure of chromatic complexity is extracted via fractal sampling of the scene image and adapted to the associated area of the birdpsilas eye view. By transferring the chromatic complexity the roadway pattern is segmented arid extended in the birdpsilas eye view. Through experimental studies, roadway patterns were demonstrated to be extended beyond the perspective in the scene images prior to physical arrival.

This paper integrates Ethernet and control area network (CAN) with the TCP/IP communication gateway. The developed system has been applied to a remote control system for an AC 400 W servo motor to verify the proposed adaptive Smith Predictor control method with the time-delay estimation algorithm. The time delay effect, defined as the round-trip time (RTT), between the application layer of the server and the application layer of the client, has been measured and analyzed. Moreover, results indicate that NCS performance is degraded, and may even become unstable mainly due to the serious network time delay in a stochastic nature mainly occurred in the Ethernet. The Smith predictor is adopted to eliminate the constant time delay. However, the delay in a commercial network is time varying and it depends on the number of end users. An adaptive Smith predictor control scheme is developed in this paper by applying the on-line estimation to further improve control performance of the proposed NCS with the integrated Ethernet and CAN buses. Experimental results indicate that the time delay is drifting in both bounded and random natures for the integrated Ethernet+CAN network and the proposed control approach significantly improves motion accuracy as in the NCS for an AC motor-based motion system.

In this paper, an on-line deterioration prediction method and residual life evaluation are proposed for maintenance of rotating equipment. Status of the rotating equipment is inspected by vibration measurement and a mathematical model for the deterioration of the equipment is derived in order to predict future condition of the rotating equipment. For the construction of the deterioration model, outliers in the vibration data caused by measurement errors and so on are eliminated in order to improve accuracy of the deterioration model. Residual life of the rotating equipment is evaluated from the deterioration prediction by using the deterioration model. The effectiveness of the proposed deterioration prediction method and residual life evaluation are assured by actual data of rotating equipment in thermal power plants.

We proposed and developed a novel interface to display high-quality tactile information by improving the temporal bandwidth extremely. The system is composed of two oppositely arranged speakers. A user holds the speakers in between his/her both hands while the speakers vibrate air between the speakers and the palms. The user feels suctioning and pushing sensations to the palms from the air pressure. Spatial distribution of the pressure is uniform and the user can feel pure force without any feeling of edges. As the speaker has a potential to present tactile sensation of very wide frequency range, we can present many types of high-quality tactile feeling, such as liquid, some small objects and living matter. Additionally, we implemented several interactions between the display and the user by using force sensor and acceleration sensor, which enabled us to experience emotional feeling.

This paper presents the experiment-based analysis of interior illuminance from natural lighting through clear glazed window of a reference room located in Bangkok, Thailand, during February to May 2007 as a case study. The point illuminances measured by photoconductive sensors were collected every 5 minutes and the average interior illuminance from natural lighting were then calculated instantaneously. In this study, natural lighting also aims to reduce the requirement of electric lighting during daytime (7 am-5 pm) of the reference room. If natural lighting alone cannot supply the light at the required value, the electric lighting is assumed to be switched on under top-up control method to maintain the standard illuminance level. The average interior illuminance, which comprises of natural light and electric light, is controlled to be stable at the IES standard level of 500 lux. Nine sets of high performance lamp, 56 lm/W of efficacy, are assumed to supply the light to meet the standard condition. The requirements of supplementary lighting and possible savings during the test months are finally estimated.

In this research, we aim at to develop design environment which allow changing a robotpsilas internal composition flexibly and easily by applying the RT-middleware. To achieve this, we propose to introduce the manager, named RTM-PnP manager, which supports plug and play for RT-component. This RTM-PnP manager that automatically negotiates and sets RT-middleware is investigated to reduce complex sets up procedure to use OpenRTM-aist-0.4.x. For instance, in the start-up process, the robot cannot execute the requested service if the application program failed to manage RT-component appropriately. By introducing PnP service, it becomes possible to change composition of the robot easily according to a userpsilas environment or a request. Thereby development efficiency of the robot would be improved.

Automatic detection and description of events, particularly human behavior, is one of the most challenging issues, since event interpretation is highly dependent on the target of attention, which is not uniquely specified. To tackle this problem, we propose the concept of a ldquocognitive ontologyrdquo as a framework for a system that can automatically decide the attention focus and describe the events. A cognitive ontology is structured with conceptual units which are Entities and Relations, and these units enable robot endogenous attention fixation and jumps based on a networked Cognitive Ontology. To construct a Cognitive Ontology structure, we used a Bayesian network for the relationships of an Ontological network. We evaluate the performance of a probabilistic event description by visual information using Cognitive Ontology in an experimental event description of a desktop situation.
