This research proposes a methodology to recognize the level of the vibrational intensity of a building during an earthquake with a few seconds before its maximum vibration using the P wave response. The proposed methodology is based on the Discrete Fourier Transform (DFT) and Support Vector Machine (SVM). This methodology results in an alert level that is classified according to its vibrational intensity (low, moderate and high). Each building could have different alerts in the event of an earthquake since may have different natural frequencies. A prototype implemented with a Raspberry Pi V4 B embedded system, two acceleration sensors called MPU6050 based on MEMS and a Wi-Fi antenna, mainly, is used. Also, filters were used to attenuate noise. The STA/LTA algorithm is used to compare the detection time. The results show that it is convenient to use the methodology for two main reasons. Firstly, this uses one tenth of the samples needed in the STA/LTA algorithm for detection and with the same efficiency. Secondly, the classification of the alert level in the building has a correlation greater than 0.8 with the PGA of the seismic signal that occurred in its structure.","PeriodicalId":212534,"journal":{"name":"2023 Argentine Conference on Electronics (CAE)","volume":"50 1-2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132286892","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}

On the other hand, for the compression of images with rectangular grids, where there is far more research, the use of the wavelet transform is a strategy that allows high levels of performance to be achieved; two examples of image compression systems based on wavelets are the JPEG2000 standard and the IW44 algorithm used by DjVu, both currently still in use. In this work we are interested in evaluating the feasibility of a hexagonal grid image compression system using wavelets for implementation on a configurable sensor made of pixels on a hexagonal grid previously developed by our group. In order to do this, theoretical and implementation aspects of image compression with wavelets on hexagonal grids of pixels are studied first. A complete hexagonal image compression system is then implemented using Haar like wavelets and an adaptation of the coding algorithm for rectangular images SPIHT. To evaluate the performance of the proposed system, a comparison is made with its rectangular analogous version by testing with multiple images. Finally, a simple test is carried out on the configurable sensor that shows the it is possible to directly read the decomposition coefficients instead of reading pixel by pixel.","PeriodicalId":212534,"journal":{"name":"2023 Argentine Conference on Electronics (CAE)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133726095","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}

Since 2014, the collaboration has tested different electronic components in space environments using different versions of its flagship testing platform: LabOSat-01. Some of the electronic components tested in the past include resistive switching memories and dosimeters based on field-effect transistors. A daughter board was developed for LabOSat-01, which was used to characterize four ONSEMI MicroFC-60035-SMT Silicon Photomultipliers in DC mode. Each Silicon Photomultiplier was enclosed in a light-tight aluminum housing along with an LED to test it under controlled illumination.In this Proceeding, we report the results obtained after 2 and a half years (958 days) of measurements of Silicon Photomultiplier performance in Low Earth Orbit. The temperature range of the electronics and sensors was −7 °C to 4 °C. The DC-DC boost converters used to bias the Silicon Photomultipliers remained operational at the set bias voltage of 29.1 V. An increase of expected Silicon Photomultiplier current under various LED illuminations was observed and these values increased with mission time. Several hypotheses are under evaluation, like gradual damage to the electronics, to the light-tight housings, or both.","PeriodicalId":212534,"journal":{"name":"2023 Argentine Conference on Electronics (CAE)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128229720","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}

Such devices have dedicated systems for monitoring biological signals, such as heartbeat and blood oxidation, and some of these devices already have the ability to provide measurements of electrocardiogram (ECG) and blood pressure signals. Additionally, these devices also feature wireless connection via Bluetooth orWi-Fi communication protocols. Both modern instrumentation and communication systems require the digitization of analog signals by means of analog-to-digital convertes (ADCs) for further digital signal processing. This work presents the design of a Successive Approximation Register (SAR) ADC for low voltage applications with 10 bits and 5 kSPS in asynchronous operating mode. The ADC is designed in 180-nm CMOS technology and operates at a nominal supply voltage of 0.5 V. Schematic-level simulations indicate that the ADC reaches a signal-to-noise-to-distortion (SNDR) ratio of 61.36 dB, leading to an effective number of bits (ENOB) of 9.90 bits. The spurious-free dynamic range (SFDR) is 73.19 dB, and the total power consumption of the ADC is 1.43 μW.","PeriodicalId":212534,"journal":{"name":"2023 Argentine Conference on Electronics (CAE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122723755","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}
