However, their high susceptibility to noise and motion artifacts demands robust algorithms for reliable sleep staging. We propose a lightweight and physiologically inspired framework that combines spectrum derivative features with the Flexible Variational Information Bottleneck (FVIB). Spectrum derivatives enhance time–frequency representations of ocular dynamics, while FVIB provides strong regularization and post-hoc calibration, ensuring robustness under noisy conditions. Experimental results demonstrate stable and balanced performance across sleep stages, highlighting improved discrimination of both transitional and stable sleep states under noisy conditions. By avoiding Electroencephalography (EEG) and targeting low-power, embedded deployment, our method enables continuous and personalized sleep analysis via personal or home monitoring systems, paving the way for accessible consumer health technologies.","PeriodicalId":13208,"journal":{"name":"IEEE Transactions on Consumer Electronics","volume":"72 3","pages":"6069-6076"},"PeriodicalIF":9.9,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148837093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike existing solutions with limited operating ranges, this paper first develops an ESR-aware analytical model for single and multi-receiver DWPT systems, quantitatively revealing the influence of ESRs. Leveraging these theoretical insights, a configurable modular multi-receiver DWPT system using LCC-S compensation topology is proposed, where receiver units are integrated through series-connected AC terminals and parallel-connected DC links. This architecture achieves near-linear power scaling without redesign, unchanged CV outputs across the entire power range, and communication-free current/power sharing. Experimental validation on a 24V/400W prototype under diverse conditions including load variations (10-400W) and multi-receiver scenarios demonstrates exceptional performance. The system maintains 24V output with only 3.13% fluctuation while achieving >90% peak efficiency, significantly advancing DWPT technology for voltage-sensitive applications.","PeriodicalId":13208,"journal":{"name":"IEEE Transactions on Consumer Electronics","volume":"72 3","pages":"6276-6287"},"PeriodicalIF":9.9,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148837102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome these drawbacks, this paper presents a novel HB type 5LI with low switch count for transformer-less solar PV applications where the SC can be charged during each switching cycle. Other advantages of the proposed topology include reduced total blocking voltage of the switches, maximum DC-bus utilization, low SC voltage ripple, symmetric operation, reduced SC charging current and low losses. All the modes of operation and SC design method are presented. A thorough comparison has been carried out with the existing topologies to showcase the advantages of the proposed topology.

Existing research largely relies on skeletal features or trajectory prediction, which demonstrates limited performance in complex scenarios. A Micro-Motion Context Fusion Network (MMCF-Net) is proposed to address these limitations. First, a high-resolution spatiotemporal attention module is constructed that captures sub-pixel-level micro-motion features such as head direction shifts, center of gravity adjustments, and limb pre-activation through deformable convolution and dual attention mechanisms. Second, a hierarchical multi-modal context encoder is designed that adaptively fuses traffic element semantics, vehicle dynamics, and perspective-corrected spatial relationships. Finally, a dynamic weight allocation network is introduced that implements optimal combination of micro-motion features and contextual information based on scene complexity.

Video anomaly detection (VAD) confronts dual challenges: the complexity of anomalous events and the scarcity of labeled data, further compounded by environmental noise in real-world deployments. To address these issues, we propose a weakly supervised VAD framework that leverages Large Language Models (LLMs) for enhanced semantic understanding. The proposed model integrates Sequential Context-Aware Temporal (SCAT) modeling to capture spatiotemporal patterns while suppressing noise through refined attention mechanisms, and Multi-Perspective Semantic Label Generation (MPSLG) to produce semantically rich labels via LLM-based prompt engineering. SCAT strengthens temporal feature learning and noise resilience, while MPSLG provides high-quality semantic supervision, jointly enabling accurate and interpretable anomaly detection. Extensive experiments demonstrate substantial performance gains, achieving 83.82% average precision on XD-Violence for coarse-grained detection and 30.79% average mean average precision for fine-grained localization, outperforming state-of-the-art methods and validating effectiveness in both urban surveillance and consumer applications.","PeriodicalId":13208,"journal":{"name":"IEEE Transactions on Consumer Electronics","volume":"72 3","pages":"7250-7265"},"PeriodicalIF":9.9,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148837297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We first classify common attack vectors, including jamming, spoofing, eavesdropping, and data injection, and evaluate their impact across different system architectures. We then highlight system-specific vulnerabilities and assess corresponding mitigation strategies based on feasibility and implementation complexity. We present a Secure Integrated Sensing and Communication (SISAC)-enabled RIS framework designed to improve localization, sensing, and communication in RIS-assisted systems. Unlike traditional radio localization methods that depend on synchronized Base Stations (BS) and Time of Arrival (TOA) or Angle of Arrival (AOA) estimates, the introduction of RIS offers additional geometric reference points, thereby significantly enhancing localization accuracy. In the sensing domain, we focus on RIS-assisted localization and highlight that the Fisher Information Matrix (FIM) is employed to determine the theoretical lower bound on the estimation accuracy of sensing metrics, which in turn guides RIS placement and configuration for improved coverage. Simulation results demonstrate that RIS directional selectivity significantly enhances the Signal-to-Noise Ratio (SNR) and the secrecy rate for the intended user while degrading performance for unintended locations. Specifically, simulation results quantify the impact of RIS configuration on SNR, MSE, secrecy-related metrics, and localization bounds, while experimental measurements using an RIS-assisted OFDM testbed validate the proposed anomaly detection mechanism under realistic propagation conditions. To validate the proposed framework, we implement a practical RIS-assisted anomaly detection testbed using pilot-aided OFDM and 4096 discrete RIS configurations. A novel detection algorithm jointly evaluates received SNR and Mean Squared Error (MSE) of channel estimation to flag potential eavesdroppers without requiring prior knowledge of their positions. Experimental results confirm that the proposed method enhances physical-layer security by achieving a consistently positive secrecy rate for legitimate users, while degrading the performance of detected eavesdroppers.","PeriodicalId":13208,"journal":{"name":"IEEE Transactions on Consumer Electronics","volume":"72 3","pages":"7579-7601"},"PeriodicalIF":9.9,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148836624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
