The pressure regulator is a substantial element in a pneumatic system. A relief-type precision pressure regulator is commonly used in order to control the supply pressure of actively controlled pneumatic vibration isolator. In this paper, firstly, we propose a pneumatic pressure regulator that achieves precise pressure control and quick response. The regulator consists of an isothermal chamber, a servo valve, a pressure sensor, a quick response laminar flow sensor (QFS), and a pressure differentiator (PD sensor) which we have developed. Slight changes of pressure in the chamber can be detected by the PD sensor and it is fed back to the servo valve to maintain the pressure at a desired value. The effectiveness of the developed regulator was confirmed experimentally in comparison with commercially available pressure regulators. Then, the developed regulator was applied to an actively controlled pneumatic vibration isolation table, in order to regulate the supply pressure. The effectiveness of the developed regulator is also shown in the experiment, especially in terms of avoiding affection from the disturbance given upstream of the regulator.

This paper is concerned with the design of Multi-Inputs and Multi-Outputs (MIMO) predictive PID controllers, which have similar performance to that obtainable from model-based predictive controllers. A new PID control structure is defined which incorporates the prediction of future outputs and uses future set point. A method is proposed to calculate the optimal values of the PID gains from generalised predictive control results. A decentralized version of the predictive PID controllers is presented and the stability of the closed loop system is studied. Simulation studies demonstrate the superior performance of the proposed controller compared with a conventional PID controller. The results are also compared with generalised predictive control solutions.

This letter reports on white-LED with high color rendering property. We realized the white-LED whose average Color Rendering Index (CRI) is as high as 94.2 by applying the commercial Red, Yellow, Green and Blue phosphors to near ultraviolet-LED. So far as we know, this value is the highest ever attained in white-LED around the color temperature of 5500[K]. In order to realize the good Ra (average CRI), we made a CRI simulator and simulated the spectrum distribution of white-LED with good Ra. The spectrum distribution obtained by this simulation was proved to be very useful as a landmark for realizing a prototype white-LED with good Ra.

It is known that the common mode current generated by an analog-front-end (abbr. AFE) of a modem is a main cause of radiation from external wires that are connected with the AFE. In this paper, the experiment and the analysis about the common mode current that mainly depends on an output transformer in an AFE circuit is carried out. As a result, the common mode current is generated mainly through coupling capacitances between primary and secondary windings of the output transformer. Current Transverse Conversion Loss (abbr. CTCL) is used for evaluation index for common mode current. It is confirmed that a shielded transformer with very small coupling capacitances between primary and secondary windings is not always a good solution to improve CTCL. That is because the capacitances between the windings and the intermediary shield layer connected to the ground are not balanced. Then, an output transformer with a balun is proposed for improving CTCL due to reducing the influence of the coupling capacitances.

This paper proposes a learning method for rules of soccer agents' actions in RoboCup Soccer. In general, soccer agents need to do high skilled actions in real time and they should have a mechanism to decide the actions. The soccer agents based on our method refer to some types of rules in order that they go into highly skilled actions. One type of them is the rules that are Hand-coded rules. Another type is the rules that are acquired using inductive learning and they are acquired from examples of actions, automatically. We describe the basic idea for them and indicate examples of rules.

Aboard current ships, such as the DDG 51, engineering control and damage control activities are manpower intensive. It is anticipated that, for future combatants, the workload demand arising from operation of systems under conditions of normal steaming and during casualty response will need to be markedly reduced via automated monitoring, autonomous control, and other technology initiatives. Current DDG 51 class ships can be considered as a manpower baseline and under Condition III typical engineering control involves seven to eight watchstanders at manned stations in the Central Control Station, the engine rooms and other machinery spaces. In contrast to this manning level, initiatives such as DD 21 and the integrated engineering plant (IEP) envision a partnership between the operator and the automation system, with more and more of the operator's functions being shifted to the automation system as manning levels decrease. This paper describes some human systems integration studies of workload demand reduction and, consequently, manning reduction that can be achieved due to application of several advanced technology concepts. advanced system concept studies in relation to workload demand are described and reviewed including. Piecemeal applications of diverse automation and remote control technology concepts to selected high driver tasks in current DDG 51 activities. Development of the reduced ship's crew by virtual presence system that will provide automated monitoring and display to operators of machinery health, compartment conditions, and personnel health. The IEP envisions the machinery control system as a provider of resources that are used by various consumers around the ship. Resource needs and consumer priorities are at all times dependent upon the ship's current mission and the availability of equipment pawnbrokers.

Trajectory planning for hand-over between human and robot

Trajectory planning for hand-over between human and robot

IEEE International Workshop on Robot and Human Communication (ROMAN)

In the future, there will be many cases where robots should perform cooperative tasks with humans in daily life. We focus on a hand-over motion as an example of cooperative work between a human and a robot, and propose an algorithm which enables a robot to perform a human-like motion. First we analyze trajectories and velocity patterns of a hand-over motion performed by two humans. From this experimental results we notice that a receiver's motion, during hand-over has some typical characteristics. We then confirm that a human-like motion can be generated using these characteristics. Finally, we plan the robot's motion considering these results. Initially, two kinds of potential fields are used to generate a motion command which leads the robot along a trajectory similar to that followed by the human. In addition, more precise motion is considered at the end of the hand-over operation to guarantee accurate positioning and to soften the shock of contact. Experimental results using 2-link planar robot arm show the validity of the proposed method.

In an era of fiscal austerity, downsizing and unforgiving pressure upon human and economic capital, it is an Augean task to identify resources for fresh and creative work. The realities of the day and the practical demands of more immediate fleet needs can often dictate higher priorities. Yet, the Navy must avoid eating its seed corn. Exercising both technical insight and management foresight, the fleet, the R&D community, the Office of the Chief of Naval Operations (OpNav) and the product engineering expertise of the Naval Surface Warfare Center (NSWC) are joined and underway with integrated efforts to marry new, fully demonstrated technologies and operational urgencies. Defense funding today cannot sponsor all work that can be mission-justified over the long term because budgets are insufficient to support product maturation within the classical development cycle. However, by rigorous technical filtering and astute engineering of both marketplace capabilities and currently available components, it is possible in a few select cases to compress and, in effect, integrate advanced development (6.3), engineering development (6.4), weapon procurement (WPN), ship construction (SCN), operation and maintenance (O&M,N) budgetary categories when fleet criticalities and technology opportunities can happily meet. In short, 6.3 funds can be applied directly to ''ripe gateways'' so modern technology is inserted into existing troubled or aging systems, sidestepping the lengthy, traditional development cycle and accelerating practical payoffs to recurrent fleet problems. To produce such constructive results has required a remarkable convergence of sponsor prescience and engineering workforce excellence. The paper describes, extensively, the philosophy of approach, transition strategy, polling of fleet needs, technology assessment, and management team requirements.
