In such systems, a fault tolerant design is often necessary to enable the system to continue to provide a specified service, possibly at a reduced level of performance, rather than failing completely, in spite of system errors. One approach for achieving fault tolerance in real-time embedded systems, is to provide two versions of programs for each real-time task: a primary and an alternate. If an error in the execution of the primary of a task is detected, or if the successful completion of the primary cannot be guaranteed, then the alternate will be activated, while the primary will be aborted. This paper presents a method which provides a higher level of system dependency and reliability by effectively handling underruns and overruns in a fault tolerant real-time embedded system which uses a primary and an alternate for each real-time task to achieve fault tolerance. A main advantage of this method is that it significantly increases the chances that either the primary or the alternate of each process will be able to successfully complete its computation before its deadline despite overrunning, which significantly increases system robustness and reliability, while at the same time any additional processor capacity created at run-time due to primary or alternate underruns can be efficiently utilized, which increases system resource and processor utilization, while also satisfying additional complex constraints defined on the primaries and alternates such as precedence and exclusion relations.","PeriodicalId":138936,"journal":{"name":"2018 14th IEEE/ASME International Conference on Mechatronic and Embedded Systems and Applications (MESA)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125303046","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}

As a critical powertrain component of an electrified vehicle (EV), the performance and life of the ESS dominate the performance and life-cycle cost of the pure electric vehicle (PEV) and plug-in hybrid electric vehicle (PHEV) due to the large size of their ESS. Different from traditional power density and energy density considerations, the use of battery and UC HESS today is more geared toward the use of UCs to take over the high frequency, dynamic charge and discharge to ensure quick system response and to extend battery life by reducing its frequent charge and discharge. In this paper, the recent advance of HESS and relevant technologies have been reviewed. The state-of-the-art of battery ESS and modeling method, considering its performance degradation under different use patterns are first presented. Methods for modeling the UC and DC/DC converter in the HESS, along with various HESS architectures, are also overviewed. Energy management methods of HESS are then reviewed according to recent literature to derive appropriate energy split strategies between the batteries and UCs. Finally, various HESS-based applications from public transportation to construction machinery are discussed to illustrate the benefits of HESS.","PeriodicalId":138936,"journal":{"name":"2018 14th IEEE/ASME International Conference on Mechatronic and Embedded Systems and Applications (MESA)","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125809673","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}

It aims at detecting continuously the presence of specific very high frequencies in the input acoustic signal of an embedded system. This can be used for detecting specific animal species, and for triggering a recording system or generating alerts. Used for harmful species detection, this helps to save harvests or to protect strict nature reserves. It can also be used for detecting the presence of drones in a specific restricted area.This acoustic low power wake-up system uses a simple 16 bits micro-controller (MCU), with a strong emphasis on the low power management of the system, having a target of continuous detection for at least one year on a single standard 1.2Ah - 12V lead battery. For that, it makes the most of mixed analog and digital low power MCU modules. They are including comparators, timers and a special one present on Microchip MCU, called Charge Time Measurement Unit (CTMU). This is a driven constant current source for making time to frequency conversions at a very low power and algorithmic cost.Optimizing low power modes, this low power wake-up system based on frequency analysis has a power consumption of 0.56mW, leading to approximately 3 years of battery life on a single standard 1.2Ah - 12Vlead cell.","PeriodicalId":138936,"journal":{"name":"2018 14th IEEE/ASME International Conference on Mechatronic and Embedded Systems and Applications (MESA)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121628725","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}

Calculation of SpO2 is found by taking the ratio of the AC to the DC components of the photoplethysmograph (PPG) signals measured by the pulse oximeter. Often the AC component is hidden in noise, which conventional filtering methods are unable to effectively extract. This paper describes a robust method of peak and trough detection in the presence of high levels of noise (SNR of 13 dB) using a structure of IIR filters. Two lowpass IIR filters with a cut off frequency difference of 5 Hz are used. The lower frequency (LF) cutoff filter extracts the peaks and troughs of the fundamental pulse frequency and the higher frequency (HF) filter closely tracks the raw data so that when a LF peak/trough is found, the maximum/minimum HF value across the LF pulse period is considered the peak/trough. The cut-off frequencies of the LF and HF filters adjust to the measured heart rate to track the heart rate. Testing and comparison to the typical bandpass filter method produced a specificity of 0.97 and a sensitivity of 0.96, demonstrating the accuracy of the method.","PeriodicalId":138936,"journal":{"name":"2018 14th IEEE/ASME International Conference on Mechatronic and Embedded Systems and Applications (MESA)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131193580","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}

It is also the most sensible method if one wishes to calculate derivatives or integrals of periodic signals. In this paper, error analysis is carried out for the numerical algorithm for Weyl fractional derivatives. To derive an upper bound for the numerical error, some knowledge of the smoothness of the signal must be known in advance or it must be estimated. The derived error analysis is tested with sampled functions with known regularity and with real vibration measurements from rotating machines. Compared to previous publications which deal with error analysis of integer order numerical derivatives in the frequency domain using L2 errors, the result of this paper is in terms of maximum absolute error and it is based on a novel result on the signal's regularity. The general conclusion using either error estimates is the same: the error of numerical Weyl derivatives is bounded by some constant times the sequence length raised to a negative power. The exponent depends on the smoothness of the signal. This contrasts with using difference quotients in numerical differentiation, in which case the error is bounded by a constant times the sequence length raised to a some fixed negative power and the order of the method defines that exponent.","PeriodicalId":138936,"journal":{"name":"2018 14th IEEE/ASME International Conference on Mechatronic and Embedded Systems and Applications (MESA)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129563537","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}
