Many gaze tracking applications focus on use in personal devices such as mobile phones and PCs. However, gaze tracking in large screens poses challenges because with an increase in screen size, gaze tracking in the edge region decreases owing to the restricted range of human eye movement. In addition, as large screens are often exposed to the public, anyone can use the gaze tracking module. This m...Show More
In an autonomous driving environment, the interactive platform technology inside the vehicle is important. To this end, interactive technology that allows multiple users to interact naturally in real-time through transparent display devices and technology that combines external real-world and augmented reality based on multiple scenarios have been developed. In such a fusion technology, position/o...Show More
In this paper, the ASIC design result of magnetic induction for wireless communication system is presented. Magnetic induction system is designed for measurement of distance and sensing status of river bed. The system has a low-power design because it has to be buried in the river bed for a long time. We implemented FPGA board to verify this system, and designed ASIC including digital modem block....Show More
In this paper, an adaptive battery state-of-charge (SOC) estimation method for electric vehicle (EV) battery management system (BMS) is presented. In these days, many parts of EV have been developed with electrical systems, and it makes a growth of energy storage system named battery. Therefore, to make many type of batteries safer and more reliable, BMS is employed and implemented together in EV....Show More
In this paper, the implementation result of real-time simulation system for Ii-ion battery protection circuit module (PCM) is presented. Battery protection is one of the most important factors to protect the electrical system. Especially, as the usage of the battery increases, an accurate monitoring of battery state becomes necessary for system safety. Therefore, we implement the PCM consisting of...Show More
In case of an accident, location information is important for initial response. Therefore, in this paper, Hybrid positioning system-based location recognition technology for the safety of offshore plant workers is proposed. Generally, The zone based positioning using Zigbee communication has advantages for hardware cost and maintenance cost. The proposed Hybrid positioning system based positioning...Show More
An offshore plant industry environment has high risk of accidents, accurate position information is important for workers safety. In this paper, UWB-based triangulation algorithm and hardware are proposed for offshore plant. The distance between the tag and the AP is measured by the TWR-ToA method, and accurate results are calculated by triangulation with three or more distance values. The propose...Show More
In this paper, a detection scheme for the uplink transmission of Wi-Fi backscatter system is proposed. In the uplink transmission, a backscatter tag modulates signals from a Wi-Fi access point by backscattering. Since the reflection occurs, the backscattered signal experiences more attenuation than the direct Wi-Fi signals to a Wi-Fi reader. Most recent studies focus on effective detection techniq...Show More
This paper describes a low-power, high-performance RFID tag and wireless power transfer IC for according to the requirements of the EPC Class 1 Generation 2. Operating in the frequency ranges of 860 ~ 960 MHz, the reading operation of tag IC is the -15 dBm minimum power sensitivity. The tag IC consists of an analog part for modulation/demodulation/oscillation, a digital control logic part for cont...Show More
This paper describes a low-voltage and low-power channel selection analog front end with continuous-time low pass filters and highly linear programmable-gain amplifier(PGA). The filters were realized as balanced Gm-C biquadratic filters to achieve low current consumption. High linearity and constant wide bandwidth are achieved by using a new transconductance(Gm) cell. The POA has a voltage gain va...Show More
A fully CMOS integrated RF transceiver for ubiquitous sensor networks in sub-gigahertz industrial, scientific, and medical (ISM)-band applications is implemented and measured. The integrated circuit is fabricated in 0.18-mum CMOS technology and packaged in leadless plastic chip carrier (LPCC) package. The fully monolithic transceiver consists of a receiver, a transmitter, and an RF synthesizer wit...Show More
