In this paper, A telemetering control system for the HDTV SMPS Aging System is developed. Manual Aging System is usually used to measurement of a produced SMPS. But in this system, the respective operator is arranged and monitoring the test cycle visually- According to an excess of the test time and mistakes of an operator, the reliability makes come to be low. Therefore as using the telemetering control system, it improves a productivity and a reliability of the HDTV SMPS. In the developed system, elec1rical signal is measured from aging system, and converted into the digital signal. Also the telemetering control system is composed of many units - telemetering control units for collecting the data, data relay units for the digital transmission service, data division for the multichannel realization.

In this paper presents a new technique (stain-telemetering) for detection of coated tool failure in face milling processes. In the cutter body, the strain signals received from the transmitter are transformed into frequency modulation(FM) signals in face milling processes. The receive which is placed near by the Vertical milling machine receives the FM signals, then the signals are sent to a computer, which shows the tool failure. In this paper, A on-line monitoring of the tool failure detection system based on the strain-telemetering apparatus has been represented.

This Paper describes technique for the design of system for telemetering the water temperature at sea. This telemetering device adopts FM-FM system, and its main carrier wave is 146.2MHz. The transmission power is about 1W, and the available distance of transmission is 2km. The telemetering time for the transmission and pause is controlled automatically by the CMOS programmable timer. The water temperature is measured by the electronic thermometer, it is varied by V-F converter which is built to a linear voltage controlled oscillator. The results of the experiment at the place where the receiver is off 2km from the transmitter, the water temperature measured with the mercury thermometer well agree with that of the telemetering device.

In this Paper telemetering system for home automation is Proposed and implemented. Proposed and developed systems are composed with a home server and a few clients which send metering data of gas electric power water and home security to home server using power line communication. Management computer located in office of apartment complex collects all kinds of measured home data from each home server with multi drop communication by UDP Protocol A simple ASK method is used for power line communication Collected data from each home can be used for issuing the bill of each house and web service. The experiments were carried out under laboratory environment using various kinds of electric home appliances to ascertain the performance.

In this paper present a new technique (strain-telemetering)for detection of coated tool failure in face milling processes. In the cutter body the strain signals received fro the transmitter is transformed in to frequency modulation(FM) signals in face milling processes. A receiver which is place near by the Vertical milling machine receives the FM signals, then the signals will be sent to a computer which determines whether th tool is failure. And machined surface of workpiece is detected by the SEM. In this paper, A on-line monitoring of the tool failure detection system based on the strain -telemetering apparatus has bee represented.

This paper addresses a telemetering device which uses RF transceivers and a mobile-phone. Locally collected data arc encoded with a BCH error correcting code and transferred to a receiver through a RF module. The receiver-side RF module decodes the transferred data and then repetes them to a mobile-phone. Lastly, the mobile-phone hands over the data through a wireless phone network to a host computer in the internet.

The MAFSAP(Monitoring and Forecasting System of Air Pollution) was developed to measure the weather and air pollution data automatically, then make them input to microcomputer and analyze them for monitoring and forecasting air pollution at all times. And the air pollution telemetering systems installed at Young-Dong Thermal Power Plant was analyzed and an ideal telemetering system utilizing MAFSAP was suggested.

This paper is concerned with automatic telemetering system which reads the consumed quantity of electricity, gas, and piped water. The existing metering method such that a meterman visits households and directly reads meters can cause several problems, including violation of privacy and the possibility of criminal accident, as well the inefficiency in viewpoint of system operation and rate notification. In this paper, we propose a new automatic telemetering and rate notification system, in which the system reads several meters at remote locations and notifies the rates to the customer's cellular phone with short message service(SMS). The proposed system has been developed by using CDMA mobile communication modules and personal computers. This system can operate only with cellular communication network even without wired-internet facilities. In particular, the developed system can provide home security and convenience as well as cost reduction, and thus be applied to intelligent home networks.

This paper described on the availability fo the underwater telemetering by the ulterasonic multi-beam system made as a trial to expand detectable range of the fish school. The ultrasonic multi-beam system consisted of four transducers which reconstructed with the existing net recorder. The experiment for the telemetering carried out in the set net fishing ground. The results obtained are summerized as follows: 1. The detectable distance of a target by the linear arrangement of four transducers increased according to the sea depth and the interval between transducers. 2. When the fish school in the entrance of set net was measured by linear arrangement of transducers it was entered in depth of 2.5~3.5m at near position of leader, and in depth of 3.5~4.5m at near position of door net. 3. The deviations of error between the actual position and the position by transducer in case of the target depth 1m, 1.5m, 2m were 5.9~27.1cm, 3.2~28.9cm, 3.5~25.8cm respectively, and 68.3% probability radius of them were 14.6cm, 17.7cm, 17.0cm respectively. 4. When the fish school in the fish court of set net was measured by plane arrangement of transducer it was entered toward the opposite direction of tide current. 5. The available distance of telemetering by the multi-beam transducer was 1.8km and the telemetering was possible to control everywhere in case of sea depth more than three meters.
