However, embedded microcontrollers are still equipped with low-speed interfaces as universal asynchronous receiver/transmitter (UART), serial peripheral interface (SPI) or inter-integrated circuit (I2C). These interfaces provide the physical layer for sending or receiving sensor data. The main advantages being the low power associated for driving the interfaces and the low price for having them as integrated peripheral in the microcontroller. Besides being a local communication interface, UART can also be used for inter-device communication (e.g. device status, sending erroneous messages, performing software update). In the previous scenarios, UART data transmission is not safe and can be prone to errors. The paper presents a framing that improves UART communication for real-time embedded devices. Beside the message frame also a message handle service is implemented such that the communication process does not interfere with the device’s real-time operation.","PeriodicalId":426485,"journal":{"name":"2021 IEEE 27th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134520084","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}

This paper addresses the aforementioned promising topic, by studying in a 3D Simulation a PoC Filter EMC performance. The contribution is demonstrated by the step-by-step guidance on how to tackle EMC environment of a PoC Filter (this topic has not been addressed in the literature so far). The novelty stems from calculating return loss and insertion loss for this type of filters and from comparisons that are made between 3D and Schematic simulations (using CST PCB Studio and CST Microwave Studio).","PeriodicalId":426485,"journal":{"name":"2021 IEEE 27th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130862506","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}

One of its main features is the robotized version called the FluidFM BOT, which can perform up to 30-40 Single-Cell Force-Spectroscopy (SCFS) measurements per day exceeding previous SCFS acquisition methods. The user software of the FluidFM BOT allows the user to measure the inverse optical lever sensitivity (InvOLS) and spring constant (k) of the applied FluidFM micropipette cantilevers used for SCFS recording, which parameters directly scale the obtained voltage values from the two-segmented photodetector. However, the user software miscalculates the InvOLS values and does not allow exporting measurement parameters Fmax, Emax, and Dmax, which are characteristic of individual SCFS Force-Distance (FD) curves. Also, exporting individual FD-curve plots is not possible. Here we show a software specially developed in Matlab for the correct acquisition of InvOLS values, plotting and exporting of FD-curves and their parameters. The software allows users to interfere, but it is partially automated to enable smooth data evaluation procedures. The software will be available free of charge on the link provided at the end of the manuscript.","PeriodicalId":426485,"journal":{"name":"2021 IEEE 27th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115061637","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}

Analytical techniques for food analyses are usually time-consuming, require sample pre-treatment and employ high-quality devices. This paper details a low-cost application for the examination of pasteurized milk. The samples were analysed using a 6-channel visible sensor which acquires spectral data from 430 nm to 670 nm. It has a low power consumption and can be easily interfaced with other devices that use serial communication. The spectrometric setup was encapsulated within an opaque container to prevent any external light to reach the surface of the sensor. The analysed samples were placed between the light source and the visible sensor to detect any intensity changes caused by milk degradation in time. To prevent any displacements between the systems components, a 3D-printed holder was designed and printed to support the sensor, the light source and the cuvette with the sample. The purpose of this work is to investigate if visible spectroscopy can be used to validate milk freshness. The sensor acquired data for several days. The results show a change in the spectral data read by the sensor which correspond with the moment the analysed milk turned sour. This sourness of the milk is the results of the fermentation process which causes lactose to turn into lactic acid.","PeriodicalId":426485,"journal":{"name":"2021 IEEE 27th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128294460","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 acquisition module is capable to realize accurate, safe and reliable multipoint temperature measurements in a range from -35°C until 140°C. Thermal analysis is realized using multiple LM35 sensors placed in critical points of the tested modules. The main component of the system is the PIC18F4550 microcontroller, a low-power and versatile device that provides all necessary resources for acquiring and processing up to ten analog input signals. The number of input channels can be relatively easily increased by using an external high-speed multiplexer. Relying on the internal analog-to-digital converter existent in the structure of the microcontroller, the proposed system operates with a resolution of 10 bits and a maximum sample rate of 40 kS/s for each input channel. The acquired data are processed and graphically displayed using a dedicated LabVIEW software application running on an external PC. The connectivity between the data acquisition system and the PC is realized through USB interface. Compared with the analysis methods based on thermal cameras, the proposed solution has the advantage of a lower cost, the obtained results are easy to interpret and, in many cases, the accuracy is similar or even better, especially when test are performed on series of electronic modules with configurations that generate reflections.","PeriodicalId":426485,"journal":{"name":"2021 IEEE 27th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127427936","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}
