There is a growing awareness in the electronics manufacturer that system level ESd robustness is an important requirement for reliable products. System level ESd testing is today applied to a wider range of products than ever before. designing ESd robust systems can be very challenging, especially for systems which integrate advanced technology integrated circuit (IC) components. While IC level ESd design and the necessary protection levels are well understood with reliability test from CdM or HBM model, system ESd protection strategy and design efficiency have only been dealt with in an ad hoc manner. We wish to explore realistic system or chip ESd protection requirements and strategies for normal operating IC chip or system, and therefore we have to establish the realistic ESd generator model to be incorporated with chip or system under investigation. Many of the most severe system level ESd design problems can be then traced to the affected location of system or chip with analyzing the residual ESd stress after injection and propagation. With this help, we can then adopt a consolidated approach to system level ESd design, and validate future success in building ESd robust systems through simulation in advance. © 2019 The Institute of Electronics, Information and communication Engineer.

Biological neural circuits at various levels exhibit rapid adaptability to diverse environmental stimuli. Such fast response times imply that adaptation cannot rely solely on synaptic plasticity, which operates on a much slower timescale. Instead, circuits must be inherently hyper-flexible and receptive to switches in functionalities without changes in network structure. This biological flexibility is a fruitful mechanism for constructing artificial reconfigurable circuits, whether they are spiking or non-spiking. In this study, we demonstrate that a four-neuron circuit can rapidly and controllably switch between 24 unique logical functions while maintaining the same set of synaptic weights. Moreover, we show that this reconfigurability works for several different underlying neuronal architectures and strikingly can be applied to a network composed of any sigmoid-shaped activation function. We conclude with proof-of-concept applications showing that we can perform standard tasks, such as a full-adder, as well as event-based conditional computing, such as detecting unexpected motion.

Since system level ESd testing is today applied to a wider range of products than ever before. designing ESd robust systems can be very challenging, especially for systems which integrate advanced technology integrated circuit (IC) components. Solving ESd problems can lead to other complications on layout of chip and board level with verification. Since the ESd stress current makes its own path from injection spot to pins of IC under test or adjacent metal parts, such as trace or ground, we need to investigate those possible current paths forming a propagating chain on PCB of mounted component devices. A key finding of ESd design for sensitive IC mounted PCB is the analysis of the stress reaching IC / module/system level circuit so that best practice ESd protection and controls can be achieved. In this paper, we investigate the effect of different return paths on various ground plane configurations on board level ESd problem with the utilization of ESd generator model previously validated. © 2019 The Institute of Electronics, Information and communication Engineer.

This study examined whether the learning concentration of students with attention deficit hyperactivity disorder (AdHd) or autism spectrum disorder (ASd) can be improved through participation in one-on-one learning activities. A total of 13 students with AdHd or ASd were recruited to participate in various weekly one-on-one learning activities, in an effort to improve the concentration of students with special needs. Brainwave data were collected through electroencephalography and analyzed to explore students' concentration performance in different learning activities. To achieve the objective of this study, a multi-baseline design (ABAB), a type of single-subject design method, was employed. The experiment spanned 21 weeks, covering a fall and a spring semester: the first three weeks were defined as the 1st baseline phase, the 4th to 10th weeks as the 1st experimental phase, the 11th to 13th weeks as the 2nd baseline phase, and the 14th to 21th weeks as the 2nd experimental phase. The learning activities took place in the morning self-study period once a week, and the experiment was only suspended during two of the weeks because of school events. The purpose of the two baseline phases was to collect students' brainwave data. Students' brainwaves were measured for two minutes under two scenarios; first, while they were relaxed with eyes looking straight ahead; second, they were reading a passage. The purpose of the two experimental phases was to gradually enhance students' concentration by training them to perceive their own emotions through brainwave lamps. Initial results yielded different brainwave data for students with different types of disorders. After participating in the training on learning concentration, some students demonstrated improved concentration; however, after the 2nd experimental phase, students' concentration declined. The reason was that the activities in both experimental phases were identical, and thus, they no longer provoked students' inte

The trend of smart vehicle for ever increasing need on safe and comfortable driving environment, the more electronic equipment and electronic control unit (ECU) are implemented on automotive. Since the multi-purpose micro-controllers are widely adopted by automotive industry for advanced functional features, their EMI characteristics is crucial for safety issue because of possibly degraded communication signal due to EMI noise. There are also increasing RFI problem resulting from high-speed digital devices interfering wireless communication module on board. We therefore will investigate the EMI and RFI phenomena of micro-controller under different clock frequencies and operating voltages in this study. We will utilize the chip level EMI measurement methods IEC 61967-2[1] and IEC 61967-3[2] with self-designed high-sensitivity near-field probe.

With the development of IC nano-meter technologies advancing toward higher operating frequencies and the trend of integrated various wireless communication systems for smart autonomous car, the self-driving system with highly integrated high-speed digital circuits and multi-radio modules are now facing the challenge from performance degradation by even more complicated platform EMI noisy environment. Thus the radiated EMC problem has become a crucial issue for IC adoption by automobile industry. Since TEM Cell could be used for EMI test (IEC 61967-2[1]) and EMS test (IEC 62132-2[2]) on chip or module level, we therefore design and investigate the structure of TEM cell and its characteristics for IC EMC test in this study. Finally, we will utilize the TEM cell designed in this study to measure the EMI emission generated from flash memory under different operation and working conditions.

This study aimed to integrate magnetic resonance imaging (MRI) and related somatosensory evoked potential (SSEP) features to assist in the diagnosis of spinal cord compression (SCC). MRI scans were graded from 0 to 3 according to the changes in the subarachnoid space and scan signals to confirm differences in SCC levels. The amplitude, latency, and time–frequency analysis (TFA) power of preoperative SSEP features were extracted and the changes were used as standard judgments to detect neurological function changes. Then the patient distribution was quantified according to the SSEP feature changes under the same and different MRI compression grades. Significant differences were found in the amplitude and TFA power between MRI grades. We estimated three degrees of amplitude anomalies and power loss under each MRI grade and found the presence or absence of power loss occurs after abnormal changes in amplitude only. For SCC, few integrated approach combines the advantages of both MRI and evoked potentials. However, integrating the amplitude and TFA power changes of SSEP features with MRI grading can help in the diagnosis and speculate progression of SCC. © 2023, The Author(s).

Background: In post-stroke rehabilitation, functional connectivity (FC), motor-related cortical potential (MRCP), and gait activities are common measures related to recovery outcomes. However, the interrelationship between FC, MRCP, gait activities, and bipedal distinguishability have yet to be investigated. Methods: Ten participants were equipped with EEG devices and inertial measurement units (IMUs) while performing lower limb motor preparation (MP) and motor execution (ME) tasks. MRCP, FCs, and bipedal distinguishability were extracted from the EEG signals, while the change in knee degree during the ME phase was calculated from the gait data. FCs were analyzed with pairwise Pearson’s correlation, and the brain-wide FC was fed into support vector machine (SVM) for bipedal classification. Results: Parietal–frontocentral connectivity (PFCC) dysconnection and MRCP desynchronization were related to the MP and ME phases, respectively. Hemiplegic limb movement exhibited higher PFCC strength than nonhemiplegic limb movement. Bipedal classification had a short-lived peak of 75.1% in the pre-movement phase. These results contribute to a better understanding of the neurophysiological functions during motor tasks, with respect to localized MRCP and nonlocalized FC activities. The difference in PFCCs between both limbs could be a marker to understand the motor function of the brain of post-stroke patients. Conclusions: In this study, we discovered that PFCCs are temporally dependent on lower limb gait movement and MRCP. The PFCCs are also related to the lower limb motor performance of post-stroke patients. The detection of motor intentions allows the development of bipedal brain-controlled exoskeletons for lower limb active rehabilitation. © The Author(s) 2024.
