This research develops a real-time Brain-Computer Interface (BCI) for interpreting eye blinks as a means of hands-free communication, particularly useful for individuals with limited mobility or in high-focus tasks. Combining machine learning (ML) and signal processing, the study detects voluntary eye blinks with high accuracy. Data from 20 participants were analyzed using a random forest classifier, achieving accuracy between 85.29% and 92.15%. A peak detection method further improved blink detection accuracy to over 98%. This system enhances accessibility in various interactive environments, improving life quality for those with disabilities. © 2024 IEEE.

A state-of-the-art fluorine-free word line (WL) molybdenum (Mo) process has been established for future 3D flash memory. Application of Mo to WLs can accelerate scaling of cells in both the vertical and horizontal directions with lower RC delay and lower leakage failure rates compared to traditional tungsten. In addition to being fluorine-free, key attributes of the process are optimization of Mo recess by innovative chemical and improvement of Mo filling to remove oxygen residue in Mo voids. These techniques can extend the scaling limit of 3D flash memory. © 2024 IEEE.

We address a trade-off issue between chip assembly time and positioning accuracy in a traditional pick- and-place method using self-assembly technology driven by liquid surface tension. This method allows 16-layer stacking of 50-µm-thin chips fabricated via Plasma Dicing Before Grinding (PDBG). The surface tension of liquid droplets enables sub-50 nm alignment accuracy even with manual chip placement. By identifying key parameters such as pre-alignment position and liquid volume/distribution, we optimize the self-assembly process for High Bandwidth Memory (HBM) applications. Additionally, we discuss the effects of liquid bridges and wetting contrast between the chip surface and sidewall on multi-layer stacking. © 2024 IEEE.

Achieving a simple, non-contact, non-invasive, and non-disruptive method for measuring and monitoring vital signs, including respiratory signals, is crucial in this field of research. This paper aims to implement algorithms for extracting respiratory signals and breathing rates from thermal facial images. Unlike many previous studies, where the algorithm was validated under resting conditions, this paper designs a protocol to capture a diverse range of respiratory activity datasets in varying conditions. Data were collected from six healthy individuals, with thoracic and abdominal contact-based respiratory signals used as reference signals. Processing steps, including robust facial tracking in thermal images and precise selection of target areas around the nose is implemented to extract respiratory signal and rates from the thermal video. The effectiveness of the proposed computational method is assessed through both quantitative and qualitative metrics, considering a variety of breathing patterns beyond just resting conditions. © 2024 IEEE.

The clutter generated by multiple transmitting pulses overlaps in the time domain, which results in the two-dimensional aliasing of the range domain and Doppler spectrum of the clutter for the medium and high repetition frequency radar. In the simulation of different battlefield environments, a large number of range-Doppler grid units will be generated. It is necessary to establish a simulation model of aircraft based on GPU-CPU architecture to solve the track, attitude and radar parameters in real time to generate grid units, and then add antenna and sea situation information to calculate the cross-heavy sea clutter. This is of great significance for rapidly generating large span heavy sea clutter and improving the speed and reliability of sea clutter simulation. © 2023 SPIE.

In these days, construction sites are facing workforce shortages caused by declining labor and lack of young workers. Therefore, "Improve Productivity" is very important. Automation and autonomy of construction machinery is one of the solutions. As above, ICT hydraulic excavators and bulldozers are widely used in many sites, but the scope of the application is limited. In particularly, automated excavating in hydraulic excavators still has many difficulties in actual use. The root cause is needed to the complicated operation during excavation affected by the soil conditions. Since the soil conditions change anytime, if the operation is not adjusted to match to them, the efficiency will be decreased significantly. In other words, to achieve automated excavating, the hydraulic excavator must recognize variation of soil conditions first. While digging, the operator has been sensing the machine's response affected by the soil conditions to consider it and adjusting machine operation simultaneously. In other words, human senses were used to recognized soil conditions to perform efficient operations. In that case, we thought that if we could replace human senses with internal sensors of the machine, the machine could recognize the soil conditions by itself. In this study, based on this hypothesis, we conducted measuring sensor data during excavating in various soil conditions (e.g. hardness, materials…). The test results indicated that the soil hardness measured by simplified N-value meter, has a high correlation with the work efficiency and bucket tooth speed calculated from internal sensor data. This implicated that the sensor data from the hydraulic excavator can be used to be determine soil conditions. In addition, there is a possibility that excavator could recognize soil conditions by itself. © 2024 International Society for Terrain-Vehicle Systems. All rights reserved.
