Timely diagnosis and detection of vascular dementia is critical to avoid brain damage. Brain imaging is an essential tool for diagnosis and determines future treatment options available to the patient. Currently, Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET), Computerized Tomography (CT) scan and carotid ultrasound are mainly used for brain imaging and vascular dementia diagnosis. However, these technologies are expensive, require extensive medical supervision and are not easily accessible. This can cause substantial delay in diagnosis and potentially lead to irreversible damage. This paper presents a first-of-its-kind, miniaturized octagonal monopole-patch antenna (OMPA) sensor for vascular dementia detection. It is designed to operate as part of a portable device and can effectively diagnose underlying causes like brain infarction, stroke and blood clots at the initial stage. The developed sensor designs are validated using microwave computational software and fabricated models are experimentally verified using artificial stroke and blood clot targets inside an artificial brain model. Simulated and measured reflection coefficient results are consistent, and target objects are detected successfully. The findings show that the prototype device is viable as an efficient, portable and low-cost alternate for vascular dementia detection.","PeriodicalId":177320,"journal":{"name":"2023 IEEE International Symposium on Circuits and Systems (ISCAS)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117261051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared to other sensors, like cameras and radars, LiDAR provides up to 64 scanning channels, vertical and horizontal field of view, high precision, high detection range, and great performance under poor weather conditions. In this paper, we propose a novel aerial traffic monitoring solution based on Light Detection and Ranging (LiDAR) technology. By equipping unmanned aerial vehicles (UAVs) with a LiDAR sensor, we generate 3D point cloud data that can be used for object detection and tracking. Due to the unavailability of LiDAR data from the sky, we propose to use a 3D simulator. Then, we implement PointVoxel-RCNN (PV-RCNN) to perform road user detection (e.g., vehicles and pedestrians). Subsequently, we implement an Unscented Kalman filter, which takes a 3D detected object as input and uses its information to predict the state of the 3D box before the next LiDAR scan gets loaded. Finally, we update the measurement by using the new observation of the point cloud and correct the previous prediction's belief. The simulation results illustrate the performance gain (around 8 %) achieved by our solution compared to other 3D point cloud solutions.","PeriodicalId":177320,"journal":{"name":"2023 IEEE International Symposium on Circuits and Systems (ISCAS)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127379696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hybrid integration of CMOS electronics and photonics realizes entirely novel system-level functionality. Photonic integrated circuits (PICs) extensively employ thermo-optic tuning for calibrating for process and temperature variations, and also for reconfiguration of these circuits. These thermo-optic phase-shifters, or microheaters, are driven by electronic digital-to-analog converters (DACs) which induce an optical phase-shift proportional to the power delivered. Thus, linear power sweeping capability is desired from the DAC. In this work, we introduce power linear DACs, or PLDACs, which are expected to become a pervasive block in hybrid CMOS-photonic circuits. The mostly-digital PLDAC designed in the TSMC 65nm LP CMOS technology comprises of a 4-bit $Delta Sigma$ modulator followed by a 4-bit current-steering DAC, a square root circuit, and the driver. The 12-bit PLDAC operates at an oversampled clock rate of 10MHz and delivers up to 24mW of power to doped-silicon microheaters in a SiP foundry process with an estimated silicon footprint of $305mu mathrm{m}times 66mu mathrm{m}$.","PeriodicalId":177320,"journal":{"name":"2023 IEEE International Symposium on Circuits and Systems (ISCAS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126076201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of these repairing methods create a small monopole antenna as a byproduct which affects its electromagnetic compatibility (EMC). Switching activity in the transmitted signal through the wire creates an unintentional emission, called emanation, according to Maxwell's equations. This emanation is usually weak and suppressed to conform to EMC requirements. However, the monopole antenna of the repaired cable helps transmit it better, increasing the SNR of the emanation and extending its detection range significantly. This creates a serious security issue as emanations contain a significant correlation with the source signal and can be exploited for information extraction. In this work, the electromagnetic aspects of the broken cable repairing process have been explored in detail. We have applied the most commonly used cable repairing methods (twisting, soldering, and butt connector) to 3 types of widely used cables (USB, power, and HDMI cable) which are broken intentionally for experimental purposes. Collected data shows that the emanation SNR increases significantly due to the repairing process with −47 dBm power at a 20 cm distance. Although emanation power varies from cable to cable, it remains detectable even at >4 m distances. This strong emanation can penetrate through obstacles and remain detectable up to ~1 $mathbf{m}$ distance through a 14 cm thick concrete wall. Along with exploring the vulnerability, a possible remedy, external metal shielding, has been explored in detail. This work exposes a new dimension of information leakage.","PeriodicalId":177320,"journal":{"name":"2023 IEEE International Symposium on Circuits and Systems (ISCAS)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123798530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
