Background: Treatment planning the correction of a transverse maxillary occlusal plane cant often involves a degree of qualitative "eyeballing", with the attendant possibility of error in the estimated judgement. A simple chair side technique permits quantification of the extent of asymmetry and thereby quantitative measurements for the correction of the occlusal plane cant. Methods: A measuring instrument may be constructed by soldering the edge of a stainless steel dental ruler at 90° to the flat surface of a similar ruler. With the patient either standing in natural head position, or alternatively seated upright in the dental chair, and a dental photographic retractor in situ, the flat under-surface of the horizontal part of this measuring instrument is placed on a unilateral segment of a bilateral structure, e.g. the higher maxillary canine orthodontic bracket hook. The vertical ruler is held next to the contralateral canine tooth, and the vertical distance measured directly from the canine bracket to the flat under-surface of the horizontal part of the measuring instrument. Results: This vertical distance quantifies the overall extent of movement required to level the maxillary occlusal plane. Conclusions: This measuring instrument and simple chair side technique helps to quantify the overall extent of surgical levelling required and may be a useful additional technique in our clinical diagnostic armamentarium.

In this paper, I made visual inspection system using Vision Board and it is consist of an illuminator (a fluorescent lamp), image input device(CCD(Charge)Coupled Device) camera), image processing system(Vision Board(FARAMVB-02), image output device(videomonitor, printer), a measuring instrument(TELMN1000). Length measurement by visual inspection system is used 100mm gauge block instead of calculating distance between camera and object, it measured horizontal and vertical length factor from 400mm to 650mm by increasing 50mm. In this place, measured horizontal and vertical length factor made use of length measurement of a injection. A measuring instrument used to compare a measured length of a injection visual inspection system with it. In conclusion, length measurement of a injection compared a measuring instrument withvisual inspecion system using length factor of 100mm guage block. Maximum error of length compared two devices a measuring instrument with visual inspection system is 0.55mm. And operation program is made up Borland C++ 3.1. By changing, it is applied to various uses.

The purpose of this study was for analysis of ease about basic bodice pattern, as the first step of the research process for the drawing method of basic bodice for women in their twenties. The five selected basic bodice were made and they were worn by FRP body The garment space of each bodice was measured by analysis of the garment space of each section in figure of polymerization of cross section by a 3-D measuring instrument. The research suggests that this compared analysis is an objective reference. This analysis not only of the area of cross section of garment space and ease but also of the girth of the body shape and wearing shape, using the PAD system and 3-D measuring instrument, can be helpful in making garment patterns.

A phase different method to evaluate the instrument error of roundness measuring instrument and the form error of specimens for the calibration of the instrument is used. An instrument with a rotary table supported by an air bearing was calibrated by using the standard balls as a standard. The calibration was carried out repeatedly by setting the same ball in 12 phase angles(per 30.deg.) on the table and by recording their roundness errors with a magnification of 100,000 times. As a result of data analysis of all the observations, readout at each of 144 orientations(per 2.5.deg.) from recorded data file, the error of performance of the instrument and the specimens are separated. In the particular instrument used in the present experiment, the error of the instrument was determined with the accuracy of 0.0164 (.mu.m) and the form error of the specimens was determined with the accuracy of 0.0264,0.0172(.mu.m), respectively. If the instrument was calibrated by using the above specimens, then the accuracy of the measurement of roundness error can be improved to about 0.017 (.mu.m).

To verify correct operation of measuring instruments, we request the verification of measuring instrument to the agency that holds inspection devices. This works requires time and cost to the company. For this reason. We proposed "Smart Network Interface Card Model" for remote control of measuring instruments. Our model based on Web adapter, can add, delete and change the program to an existing web adapter from remote system. Furthermore, more than one program can be loaded, and can be updated from the remote system of internet. And also we can change the verification requirement of measuring instrument, hence it makes more good quality and competitive power of instruments.

There are two types of expensive measuring instruments currently on the market shape measurement and roundness measurement instruments. As they are very expensive, from tens of millions to more than 200 million won, buying them is economically burdensome for small companies or individuals. Therefore, in order to integrate the shape and roundness measurements into a single transfer device, this study aimed to reduce the trial and error by 3D modeling and simulation, and we confirmed the feasibility of operation. Based on these outcomes, a prototype hybrid measuring instrument was fabricated. As a result of performance evaluation and comparative evaluation, we verified the feasibility of implementation and application of the hybrid measuring instrument.

Measuring instrument module for biosensor activity is developed using CMOS image sensor and sensor network. Most of living organism in water as water flea, fish, etc are frequently used as biological sensor for monitoring the water qualify. The activity of biosensor is changed by the quality of water. The developed measuring instrument module can easily interface to the existing instrument.

Recently, to the development of a highly information-oriented society to a large increase in dependence on power, Accordingly, it is need that active development and spread of preservation technology on accident prevention in operation electrical equipment. However, to lack of the use on maintenance technology of power equipment and to increase of power usage is growing deterioration of power equipment, this is a cause on casualties, property damage and the occurrence of disasters is a growing. GIS equipments which are operated from domestic except the equipment which manages from the big business are depend on a most visual inspection, and do inspection method or measuring instrument etc. a condition which is not supplied widely. Currently, many to measure instrument used in domestic is very expensive or foreign, it will be able to substitute this, the development necessity of the diagnosis technique and the measuring instrument is demanded.

The terms of track is a train-only line for a train service, in premises of station of a station, that the unit over the track for turnout the track from one track to another track, which it changes the course from the main track that is used for operating a train to the side track, is called a turnout The stick strength of tongue rail is adjusting uniform pressure on the both sides, the adhesion strength between a basic rail and tongue rail has to maintain over 100kg of power value to open over 1mm the ends. This study suggested developing a measuring instrument that can measure a basic rail and the stick strength of a movable rail in according with a switch, such as a switch point, and a performance test. This study ties to be helped that it improves measuring usability for the maintainers through improving quality in a stick measuring instrument, that it solves a technique in the site difficulties through improving a measuring instrument, with reducing the obstacles and expenses.
