A heterodyne laser source can be generated by several methods. The method using the Zeeman effect is frequently used due to the simple construction and the small loss of a light. However, the low beat frequency of the laser in the zeeman method limits the velocity measurement. In this article, an electronical frequency modulation algorithm is proposed to overcome the drawback of the low velocity measurement capability by increasing the beat frequency electronically. The brief analysis, the measurement scheme of the proposed algorithm, and the experimental results are presented. It is demonstrated that the proposed algorithm is proven to enhance the measurable velocity limit.

For mechanical transmissions, CAD systems provide flexibility and tools that can be used to perform analysis on components and to measure their performance even before they are manufactured. This paper represents an analytical study on a novel type of worm-face gear drive in which the worm is of duplex ZK-type. Such a gear set has two teeth flanks with different pitches, that facilitate stepless compensation of the tooth flank backlash or wear by means of the simple readjustment of the worm shaft. It can be used in applications that require an exact and even transmission of rotary movements or exact maintenance of a specific defined position, beside a high gear ratio in a compact space, high-load and shock capability, and reduced operating noise. The study was limited to mathematical modeling and numerical simulation of a gear set generation process using a novel 3D CAD simulation method. The method, suitable for the manufacturing process simulation of any type of gears provides a virtual 3D visual output with the ability to validate, within the precision limits of the CAD software, the accuracy of the calculation results. Some numerical examples showing 3D CAD teeth generation simulation of a duplex worm-face gear drive are presented. Numerical results relating to the analysis of virtually generated gear-set components are also provided in order to illustrate the developed theory. Copyright © 2006 by ASME.

The profile accuracy of the workpiece is mainly determined by the accuracy of abrasive wheel in the form-grinding process. Thus, the shaped wheel dressing becomes one of the key points in the form-grinding process. In order to grind the revolving curved surfaces grooves whose cross-sectional profiles are steep and smooth, a new NC dresser with three NC axes is developed by adding a swing axis on the basis of NC external cylindrical grinding machine. A wheel of any desired convex profile can be dressed when using the Diaform single-diamond dresser and the possible geometrical interference between the single-diamond dresser and wheel can be eliminated. By analyzing the influence of installation accuracy on the profile accuracy, a method of comprehensive error compensation is presented. The comprehensive errors can be diminished greatly to improve the profile accuracy by means of error compensation. It is proved in the experiments that the precision requirements of grinding the formed surfaces grooves can be met. © (2005) Trans Tech Publications.

The research disclosed a particle-counting device which can reliably count particles in the fixed quantity of sample solution. Let sample drop in the chip inlet, then use dielectrophoresis (DEP) force produced by separation device on the chip to separate and move specific particles to micro-pore. High reliable Coulter Principle had been introduced on this device. When the particles pass through the micro-pore one by one, recording the numbers of ion current reduction events can correctly count the quantity of specific particles in the fixed volume of sample solution. © 2005 IEEE.

The primary aim of this study was to assess the feasibility of using a soil laboratory designed for testing of industrial equipment, for the biomechanical assessment of sports movements and footwear. This was achieved by the investigation of the influence of three different footwear types on in-shoe pressures to assess cushioning provided by the footwear for two surface conditions of differing density. Six subjects each performed running trials on the two surfaces in three pairs of footwear: molded boots, boots with studs and trainers. Inshoe pressure data were collected for six running steps for each shoe-surface condition, with peak heel force values used to quantify cushioning. Within each surface condition, similar peak heel force values were obtained for each of the footwear conditions. The comparison of surfaces revealed significantly higher heel impact forces when running on the higher density surface, suggesting a lower cushioning effect of this surface condition. This study demonstrates the potential of the described novel methodology to investigate footwear-surface combinations for controlled natural soil conditions. Combining these data with simultaneously measured pressures at different soil depths will allow the development of surface designs to best cope with the forces applied by the human.

Integrated micro ammonia analysis systems (IMAAS) with micro reactor and in-plane type optical detector using Berthelot reaction and micro fluidic devices were newly proposed and investigated. IMAAS with the size of 5 cm by 5 cm and thickness of 1 mm were fabricated using MEMS processes. IMAAS were packaged with inlet and outlet tube, and optical fiber connected with in-plane type optical source and optical detector using UV epoxy bonding. Reaction rates from ammonia to indophenols at IMAAS were increased with temperatures. In case of reaction temperature of 318K, reaction time was less than 1 min. From these results, fabricated IMAAS were reproducible and suitable for ammonia analysis. For the future works, it was thought these micro systems could be used for other micro reactions for versatile species analyses as well as detections for N-containing organic species including ammonia. © 2005 IEEE.

For faultless collaboration among the surgeon, surgical staffs, and surgical robots in telesurgery, communication must include environmental information of the remote operating room, such as behavior of robots and staffs, vital information of a patient, named supporting information, in addition to view of surgical field. "Surgical Cockpit System," which is a telesurgery support system that has been developed by the authors, is mainly focused on supporting information exchange between remote sites. Live video presentation is important technology for Surgical Cockpit System. Visualization method to give precise location/posture of surgical instruments is indispensable for accurate control and faultless operation. In this paper, the authors propose three-side-view presentation method for precise location/posture control of surgical instruments in telesurgery. The experimental results show that the proposed method improved accurate positioning of a telemanipulator. © 2005 Springer Science+Business Media, Inc.
