This preliminary study explores developing and implementing upper-limb rehabilitation tools utilizing haptic feedback and 3D spatial recognition analysis in a virtual reality (VR) environment. The effectiveness of upper limb rehabilitation in post-stroke patients was investigated by analyzing the joint and gimbal range of motion (ROM), ROM ratios, and force distribution through various drawing tasks. This study evaluated the impact of different drawing patterns on joint and gimbal ROM, and the force applied during rehabilitation exercises. This study revealed significant variability in ROM across different tasks by combining ROM measurements with force data and employing heat maps for visual representation. These findings emphasize the need for task-specific adjustments to improve rehabilitation outcomes. This study highlights the potential of incorporating advanced technologies, such as VR-based tools with haptic feedback and 3D spatial recognition, to enhance patient engagement and rehabilitation effectiveness. © 2024 IEEE.

In pregnancy, diabetes is known to increase the risk of adverse maternal and neonatal outcomes. It would be beneficial to find techniques that allow early investigation of the physio-pathological mechanisms involved to provide clinicians with tools for prevention and therapies. For that, cardiotocography (CTG) is a promising tool. However, the evidence is still scarce and the impact on clinical practice little. In this study, we aim at characterizing the changes induced by gestational diabetes (GDM) on the fetal heart rate series. To do so, we performed a retrospective cohort study on a CTG dataset containing more than 20000 recordings of which 852 belong to 301 GDM-diagnosed patients. We divided the recordings by gestational age (G.A.) into 4 groups (weeks: 31-35, 36, 37,38 to delivery) and for each we identified a control population of equal size matched by comorbidities. We analyzed a comprehensive set of parameters from the time domain, frequency domain and non-linear analysis and assessed variations in median values on each feature. For all G.A. below the 38th week, we found a significant increase in the power in the movement frequency band (p © 2022 Creative Commons.

This research introduces a novel dual-pathway convolutional neural network (DP-CNN) architecture tailored for robust performance in Log-Mel spectrogram image analysis derived from raw multichannel electromyography signals. The primary objective is to assess the effectiveness of the proposed DP-CNN architecture across three datasets (NinaPro DB1, DB2, and DB3), encompassing both able-bodied and amputee subjects. Performance metrics, including accuracy, precision, recall, and F1-score, are employed for comprehensive evaluation. The DP-CNN demonstrates notable mean accuracies of 94.93 ± 1.71% and 94.00 ± 3.65% on NinaPro DB1 and DB2 for healthy subjects, respectively. Additionally, it achieves a robust mean classification accuracy of 85.36 ± 0.82% on amputee subjects in DB3, affirming its efficacy. Comparative analysis with previous methodologies on the same datasets reveals substantial improvements of 28.33%, 26.92%, and 39.09% over the baseline for DB1, DB2, and DB3, respectively. The DP-CNN’s superior performance extends to comparisons with transfer learning models for image classification, reaffirming its efficacy. Across diverse datasets involving both able-bodied and amputee subjects, the DP-CNN exhibits enhanced capabilities, holding promise for advancing myoelectric control. © 2024 the Author(s), licensee AIMS Press.

The existence of electric vehicle users who procrastinate their charging activities – delay in charging until a critically low state of charge (i.e., almost empty battery) – is acknowledged in the previous survey studies and data-driven analyses. However, the underlying reasons affecting such behavior have not been explored. This study attempts to justify whether procrastination in charging is due to larger battery capacities and users’ close proximity to charging stations. The results indicate that battery sizes can have a significant effect on EV users’ procrastination charging behavior. This study found that users with battery capacities greater than 21kWh tend to procrastinate charging since they can travel longer distances. The findings will be able to serve a broad range of EV industry stakeholders due to the emerging market and continuous improvement for achieving mass EV adoption. © 2023 Human Factors and Ergonomics Society.

Unbalanced walking is increasingly common among older adults;therefore, routinely assessing the balance of older adults is crucial. The traditional method of assessing balance uses scales, requires the supervision of a physical therapist (PT), and is time-consuming. The present study, therefore, proposes a deep learning (DL) model architecture that combines a convolutional neural network (CNN) and a long short-term memory (LSTM) network model to predict the scores of three scales, namely the Berg balance scale (BBS), timed up and go (TUG), and single-leg stance (SLS). The gait data of 15 m of walking were collected from seven inertial measurement units (IMUs) and input into the CNN-LSTM model for evaluation. The BBS and TUG only require the participants to wear two IMUs on the left and right thighs, respectively, for accurate predictions. The mean absolute errors (MAEs) of predicting the scores of the BBS and TUG are 1.2562 and 1.4016 s, respectively;however, the MAE of score predictions of SLS is higher than that of the BBS and TUG, indicating that gait data cannot be used for assessing SLS;moreover, participants only wear one IMU on the right calf for BBS and TUG evaluations, which yield MAEs of 1.4334 and 1.5229 s, respectively. The proposed system can quickly and accurately predict the scores of the BBS and TUG. The proposed model can assist PTs with making clinical decisions. © 2001-2012 IEEE.

This paper focuses on the impact of segmentation on the linearity performance of gigasample rate current-steering digital-to-analog converters (DACs). The effect of their output impedance drop and code-dependency occurring at increasingly higher data rates is studied with the purpose of deriving relevant design constraints about the segmentation scheme choice. This analysis is supported by extensive simulation results carried out with special attention to the spurious-free-dynamic-range (SFDR) and third-order-intermodulation-distortion (IM3) metrics. Lastly, a 10-bit 6.4 GS/s DAC designed in a 55-nm BiCMOS technology is presented and discussed in relation to the previously determined scenarios. Besides featuring a 65.9-dBc SFDR at 1 GHz and an IM3 < -68.1 dBc over the Nyquist band, it occupies a silicon area below 0.05 mm 2 .

Emerging applications in the Sub-THz bands need ultra-wideband amplifiers, able to cover the wide available spectrum portions with a single component. Techniques such as distributed amplifiers or stagger-tuning are commonly adopted, at the cost of power efficiency, linearity and noise figure degradation. This paper proposes a design flow for ultra-wideband matching networks with a sixth-order frequency response. The networks fit well into the layout, absorbing parasitics and embedding the interconnections for signal propagation, biasing and supply of the active stages. The networks are exploited in the design of a 3-stage D-band low-noise amplifier in a SiGe BiCMOS technology. Experiments demonstrate 105- to- $175 \mathrm{GHz}-3 \mathrm{~dB}$ bandwidth with 23 dB gain. The fractional bandwidth, in excess of 50%, is among the highest reported in similar frequency bands. Simultaneously, a very low noise figure, ranging from 5 dB to 6.5 dB, confirms the validity of the proposed approach to enhance the performance of mm-Wave wideband amplifiers.

This paper proposes a novel switch implementation for enabling transmitting and receiving (TX/RX) through one single wire in ultrasound imaging transceivers. The proposed structure consists of a resistor and two current sources controlled by a DC loop. This implementation allows driving the primary switch with the low-voltage (LV) power supply available for the transceiver front-end, while providing isolation to the front-end from the high-voltage (HV) pulses required for driving the transducer in TX mode. Furthermore, by employing a DC control loop, the design not only ensures off-isolation, but also allows having zero leakage current. The proposed TX/RX switch has been designed in a 160-nm bipolar-CMOS-DMOS silicon-on-insulator (BCD-SOI) technology with a 3.3-V supply voltage. Simulation results of the proposed structure confirm its effectiveness in achieving isolation voltages of up to 200 V peak-to-peak at 3-MHz operational frequency with -42-dB off-isolation.
