  • We propose and implement a single-wire communication protocol for thermal management systems using thin film thermoelectric modules for 3D IC cooling. The proposed single-wire communication protocol connects the temperature sensors, located near hot spots, to measure the local temperature of the chip. A unique ID number identifying the location of each hot spot is assigned to each temperature sensor. The prototype chip was fabricated by a $0.13{\mu}m$ CMOS MPW process, and the operation of the chip is verified.

  • High throughput analysis using a DNA chip microarray is powerful tool in the post genome era. Less labor-intensive and lower cost-performance is required. Thus, this paper aims to develop the multi-channel type label-free DNA chip and detect SNP (Single nucleotide polymorphisms). At first, we fabricated a high integrated type DNA chip array by lithography technology. Various probe DNAs were immobilized on the microelectrode array. We succeeded to discriminate of DNA hybridization between target DNA and mismatched DNA on microarray after immobilization of a various probe DNA and hybridization of label-free target DNA on the electrodes simultaneously. This method is based on redox of an electrochemical ligand.

  • In order for medical devices to be used outside hospital, they have to be not only of small size but also power consumption has to be kept at low level. This study investigates the feasibility of application of ADS1298 ECG single-chip solution developed by Texas Instruments Inc. for use in development of a new platform for diagnostic resting ECG. To prove the feasibility of commercial products based on the ADS1298 chip, the performance of the ADS1298 chip was measured in terms of input impedance, common mode rejection, frequency response, and input dynamic range using the testing method under the suitability criteria of the IEC 60601-2-25 standard. Result of the this study shows that commercialization of the ECG products based on the ADS1298 ECG single-chip solution that satisfies the international standards would be possible, if the manufactures take the filter characteristics into account in building a new platform for diagnostic resting ECG.

  • The genotypes of Human Papilloma Virus (HPV) are important in the carcinogenesis of uterine cervical cancer. Diagnosis of uterine cervical cancer screening has been executed using Papanicolau method (Pap) and HPV DNA Chip method. We researched the interrelation of HPV DNA genotypes in single and multiple infections and analyzed the results of Pap and HPV DNA Chip tests at Gunsan Medical Center (GMC). The correlation analysis was surveyed on collected results from 599 patients who have been tested with both Pap and HPV DNA chip tests from November 2004 to May 2010 at GMC. The inconsistency between Pap and HPV DNA Chip tests was 41.1%. The HPV DNA Chip genotype related with high risk cases were type 16 (13.5%), type 52 (10.5%), type 58 (10.1%), and type 18 (3.4%). Those related with low risk cases were type 70 (8.9%), type 6 (1.7%), type 40 (1.2%), type 11 (1.3%), and other types (14.3%). Among the 195 cases of HPV positive status, 161 cases were associated with single infection; 108 (67.1%) cases were related with high risk genotype; 19 (11.8%) cases were low risk genotype; 31 (21.1%) cases were related with other types. 29 cases were associated with double infections; 23 (79.3%) cases were high risks; 5 (17.2%) cases were mixed high and low risks; 1 (3.5%) case was low risk.

  • In this paper, we present a new interpolation method for the color filter away(CFA). In order to capture color images. typical input devices use a single chip CCD imaging sensor with color filter array. As a result, the single chip CCD does not provide sufficient color resolutions since it arranges different color filters sequentially on a single CCD, resulting in aliasing noise and loss of resolution. In order to reconstruct high quality color images, we propose to use the interpolation algorithm using high order B-splines. Experiments show promising results.

  • This paper describes the three-phase inverter system for 1/2[HP] induction servo motor, using TMS370C050 single-chip microprocessor. The Power MOSFETs are used for PWM inverter circuit because of the advantages such as less harmonic losses and smaller peak current, less torque ripples and noises. Single-chip microprocessor enables the whole controller to be simple and reduced size as well as to more stable and flexible. The basic structures are shown for the power circuit, including the protection and driving circuitry, and the control loops for inverter control functions. The experimental results are given for the prototype PWM inverter system.

  • This paper proposes a Intel 8097 single-chip microprocessor based instantaneous voltage control scheme of inverter for UPS(Uninterruptible Power Supply). There microprocessors are used to control the output voltage and frequency of the inverter, the synchronization with by-pass, and the switching of the static switch. And the status and operating conditions of UPS systems is monitored by micro processor. The inverter output voltage is controlled instantaneously with a double regulation loop so that it has very good dynamic response for the varying loads or nonlinear loads as a rectifier. And also, the software and hardware of control system is described. From simulation and experimental results, it is shown that the proposed scheme has very good performance.

  • The pulse width modulated inverters based on fully digitalized method are becoming an industrial standard. This paper describes a real time generation of fully digitalized PWM pulses and its realization by single chip microprocessor. To verify the effectiveness of the proposed technique, the algorithm is implemented by using single chip microprocessor, 8097BH. The proposed method is compared with the well known triangular comparison method through experimental results, and the speed control of a motor is experimentally done by voltage-to-frequency constant control based on the proposed PWM generation method.
