The bio-telemetry technologies, that use the wireless miniaturized telemetry module implanted in the human body and transmits several biomedical signal from inside to outside of the body, have been expected to solve the problem such as the patient's inconvenience and the limit for diagnosis. In the case of transceiver system using the wireless RF transmission method, the method of three-dimensional localization for implantable miniaturized telemetry module is necessary to detect the exact position of disease. A new method for three-dimensional localization using small loop antenna in the implantable miniaturized telemetry module was proposed in this paper. We proposed a method that can accurately determine the position of telemetry module by analyzing the differences in the strength of signal, which is received at each of the small size RF receiver array installed on the body surface.

It is required to design the RF link with sufficiently stable signal margin to minimize bit errors and improve the quality of received data in the telemetry system modulated digitally like PCM/FM. In case of the vehicle flying at a high speed, the variation of the gain pattern between transmitting and receiving antenna and the fee space loss due to flight distance cause the fluctuation of link. In this paper, KSR(Korea Sounding Rocket)- III, the first domestic liquid rocket which was successfully launched in Nov. 2002 is introduced. The SNR(signal-to-noise ratio) variation of the telemetry signal which was measured at S-band ground station, the one which was simulated considering the flight trajectory, and the attitude variation such as roll, pitch and yaw are compared, analyzed, and agree very well. In addition, two virtual flying situations are simulated and evaluated-only one antenna is equipped in one case, and rocket is roll-free in the other.

The on-board telemetry system of KSLV-1 transmits telemetry signal for the launch vehicle and satellite to ground telemetry system in real time. In ground telemetry system, antenna system acquires telemetry signals and transfers these to data processing system. Data processing system processes and recordes telemetry data and distributes it to each mission operator in order to monitor it the operation goes well or not. This document describes the configurations and functions of data processing system designed for efficient and appropriate processing of telemetry data.

In this study, we developed E.C.G telemetry system by using a digital communication method. This system is composed of a number of Ambulatory Telemetry System(ATS)'s that use for the same frequency and one center monitoring system(CMS) utilized the personal computer. The purpose of the ATS is, Therefore, to present for acqusition ECG data and transmitting to CMS. The ATS hardware is based on one chip microprocessor (8096) included A/D convert, ECG pre amplifier, ID-decoder, TRX Gateway and FM TRX module. Using the PC can be convinet to processing and deposite for long terms continued patient data.

There are three critical considerations in developing a PCM telemetry encoder to be installed in an artillery projectile. The first is the performance consideration, such as sampling rate and data transmission rate. The second is the size consideration due to the severely limited installation space in an artillery projectile and the last is the power consumption consideration due to limitations of the munition's power supply. To meet these three considerations, the best alternative is a one-chip solution. Using a commercially available TMS320F2812 DSP, we have implemented a 30-channel PCM telemetry encoder to process randomized data frames, composed of 16-channel analog data, 14-channel digital data and 2-frame synchronization channels per data frame at 10Mbps transmitting baud rate.

Purpose: The purpose of this study was to provide basic information to develop appropriate nursing guidelines for cardiac telemetry. Methods: This retrospective research was conducted to identify the current usage of cardiac telemetry and considered 1,000 patients hospitalized for telemetry. The collected data were analyzed using IBM (SPSS Statistics for Windows 21.0). Results: Four-hundred and ninety-two patients (49.2%) were diagnosed with arrhythmia and 209 (20.9%) with heart failure. Electrocardiogram (ECG) rhythm changes were detected via telemetry in 464 cases. Major arrhythmias were ventricular tachycardia (183, 39.4%) and bradycardia (99, 21.3%). Interventions after detecting arrhythmia were cardioversion (16, 3.4%), defibrillation (1, 0.2%), and cardiopulmonary cerebral resuscitation (5, 1.1%); other patients were treated conservatively with close observation (381, 82.1%). Conclusion: There was appropriate intervention in 46.4% of the considered cases with the detection of ECG changes before patient notification, which implied that cardiac telemetry could be considered for application to patients with hemodynamic instability. Clear standards and guidelines are required to determine who requires telemetry and when to end the telemetry monitoring.

In this paper, We propose variable cut-off frequency and variable sample rate small-area multi-channel digital filter for telemetry system. Proposed digital filter reduced hardware area by implementing filter banks that can variably use cut-off frequency and sample rate without additional filter banks for an arbitrary cut ratio. In addition, We propose the architecture in which sample rate can variably be selected according to the number of filters that pass through the multiplexer control. By using time division multiplexing (TDM) supported by the finite impulse response (FIR) intellectual property (IP) of Quartus, the proposed digital filter can greatly reduce digital signal processing (DSP) blocks from 80 to 1 compared without TDM. Proposed digital filter calculated order and coefficients using Kaiser window function in Matlab, and implemented using very high speed integrated circuits hardware descryption language (VHDL). After applying to the telemetry system, we confirmed that the proposed digital filter was operating through the experimental results in the test environment.
