However, the traditional EMT system needs wires to be led out from the transmitting side to the receiving side, rendering it unsuitable for in vivo biomedical implants. This study proposes a wireless EMT system tailored for the wireless capsule endoscope (WCE) application, which includes: 1) elucidation of fundamental comparison between “wired” EMT and “wireless” EMT; 2) devising a corresponding wireless EMT algorithm; and 3) a small-sized, low-power hardware architecture for the receiving side of EMT. The receiving circuit is about the size of the capsule, and consumes 4.73 mW excluding the wireless communication module. Experiment results show the effectiveness of the proposed wireless EMT.

However, existing multiview methods often necessitate well-calibrated camera parameters or rely on complex parametric models. These requirements can result in inaccuracies when camera placement is perturbed and can negatively impact the deployability. This article proposes a lightweight approach that synergistically models geometric information with spatial-temporal information without relying on camera parameters, named spatial-temporal–geometric graph convolutional network (STG-GCN). We leverage the inherent connections in multiview sequences of 2-D poses, representing them as a spatial-temporal–geometric graph (STG-Graph), which allows for the simultaneous encoding of spatial-temporal–geometric relations across various joints, consecutive frames, and multiple views. Using a unified graph to model all features, this approach reduces the parameter explosion in existing methods, caused by separate modules extracting spatial, temporal, and view axis features. Building upon the STG-Graph, an adaptive confidence-aware graph convolution (ACA-GraphConv) is proposed to mitigate the impact of unreliable 2-D poses predicted by 2-D pose estimators. This is achieved by leveraging corresponding confidence scores to adjust the graph convolution accordingly. Experimental results on two public datasets demonstrate that our STG-GCN achieves performance comparable to state-of-the-art approaches while significantly reducing parameter volume. Ablation studies also illustrate the effectiveness of our ACA-GraphConv in both monocular and multiview scenarios.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-13"},"PeriodicalIF":5.6,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143726388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, conventional current transducers of rectangular busbars are primarily designed for the dc and 50-Hz currents. Numerous industrial applications in power systems require novel technologies of ac current transducers with broader frequency ranges. Some research has achieved accurate measurement for high-frequency ac currents but often relies heavily on the known relative positions of the busbars and sensors. Thus, this article proposes a wideband current measurement method without prior knowledge of precise busbar and sensor positions, which consists of two steps. The first step is using the sensed magnetic field at the fundamental frequency to localize busbar positions, which assist in revealing the regularity of magnetic field variation with frequency. The second step is to reconstruct the currents at harmonic frequencies using the sensed magnetic field at different frequencies and busbar positions. The proposed method is demonstrated for the experiments involving different arrangements of busbar systems, and the performance of the designed wideband current measuring device is verified through experiments.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-11"},"PeriodicalIF":5.6,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143726411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SDN has been widely applied in wide-area monitoring systems (WAMSs) to enhance their fault defense capabilities. This study investigated the fault-tolerant placement problem of phasor measurement units (PMUs) and communication infrastructure of SDN-enabled WAMSs. First, a hidden Markov model was established to describe the recovery process of observable states of power nodes when the failures of power lines and communication networks occur. Based on the hidden Markov model, the availability of synchrophasors of the power node was calculated. Second, a mathematical model for the simultaneously optimal placement of the PMUs and SDN infrastructure was formulated to minimize the construction cost of the WAMS. The mathematical model was calculated using a particle swarm optimization (PSO) algorithm. Finally, simulation experiments were performed on an IEEE 30-bus system and an IEEE 118-bus system to verify the effectiveness of the proposed method. Experimental results indicate that the proposed method can effectively improve the accuracy of the state estimation, which enhances the ability of WAMSs to mitigate failure risks.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-11"},"PeriodicalIF":5.6,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143706758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, traditional e-skin proximity data struggle to effectively distinguish between intrusive object data and the data from the robot itself and the surrounding environment, making it accurately evaluate collision features of intrusive objects. This article proposes a state-matching-based method for identifying intrusive object data and evaluating collision features using e-skin proximity. By establishing a nonintrusive feature model, the process extracts the nonintrusive feature data corresponding to the current robot state through state matching and compares it with the current e-skin proximity data. This allows for the effective identification of intrusive object data and the accurate and rapid evaluation of collision features, such as approach distance (AD) and approach orientation (AO). In the static experiments, the proposed method significantly improves the accuracy of evaluating AD and AO. In the dynamic experiments, the method proposed in this article demonstrated a high degree of alignment between the evaluated values and the actual values for AD and AO. Furthermore, this article analyzes the impact of the sampling state differentiation (SD) threshold during the construction of the nonintrusive feature (NIF) model on the subsequent evaluation of the robot’s dynamic AD. It demonstrates that a lower threshold for sampling SD threshold will effectively enhance the stability of the robot’s dynamic feature evaluation. Through experiments on safe collision control of robots along predetermined trajectory, it is proven that the method proposed in this article can achieve safe collision speed control for robots in human-robot interaction (HRI) scenarios, where the robot operates at a speed of 0.5 m/s.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-12"},"PeriodicalIF":5.6,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143706701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, a neonatal POC bilirubinometer was used, and optical measurements were conducted at 455 and 575 nm wavelengths on samples containing different concentrations of bovine total serum bilirubin (TSB): 0, 16.7, 12.8, 8.4, 5.3, 3.1 mg/dL) and human-derived oxyhemoglobin (O2Hb: 0, 5, 10, 20, 40, 80 mg/dL). The voltage outputs from these samples were used to generate a calibration curve. In the pure TSB samples, the accuracy was ±0.08 mg/dl, the precision was 0.32 mg/dL, and the mean absolute percentage error (MAPE) was 23.9%. When using the model that incorporates samples with both TSB and O2Hb, the accuracy increased at ±0.04 mg/dL, the precision to 0.30 mg/dL, and the MAPE to 15.4%, showing a significant improvement in measurement performances when the O2Hb interference is taken in consideration.
