The sensor is activated when an NFC signal source (mobile phone) approaches it. In the case when the radio frequency field becomes strong enough, the NFC energy is accumulated in the supercapacitor. After the required voltage value is reached on the supercapacitor, power is supplied to the sensor control circuit and a single measurement is performed. The energy value, which is necessary to perform measurements is approximately 88.7 mJ.

Various efforts have been made to support this, mainly using vision-based and infrared sensors. However, using a single sensor inevitably introduces a single point of failure. To address this problem, we combine a vision-based sensor that detects special visual markers with a sensor that tracks an infrared beacon. We also support a more cautious landing approach for the case where these sensors temporarily fail to detect their targets. We implement our solution in the context of a mature autopilot framework, through modular extensions that are transparent to the rest of the software stack. We evaluate these mechanisms by conducting field experiments using a custom drone, activating faults in the individual precision landing sensor subsystems in a controlled way through interactive commands that are sent to the drone at runtime. The results show that our solution achieves robust precision landing under different failure scenarios while maintaining the accuracy of fault-free sensor operation.","PeriodicalId":224327,"journal":{"name":"2021 IEEE Sensors Applications Symposium (SAS)","volume":"1146 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133843436","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}

We present measurement results based on transmitted light intensities through the optical fiber as indicator for the state of charge. Cells are built with commercial electrodes in a pouch cell setup. To compensate for cross influences and stabilize the measuring signal against manufacturing tolerances, a referencing method is introduced. Thus, ratios of transmitted light intensities at different wavelengths are evaluated to avoid the use of absolute values. The obtained transmission ratios are in good agreement with the state of charge for various C-rates. Finally, possibilities towards an industrial implementation with inexpensive LEDs and phototransistors are discussed.","PeriodicalId":224327,"journal":{"name":"2021 IEEE Sensors Applications Symposium (SAS)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114635631","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}

Electroencephalography (EEG) Steady-State Visual Evoked Potentials (SSVEP) based BCI systems provide a non-invasive, inexpensive method of communication and control with minimal user training. Among many applications of BCI systems, robot control is widely used to restore motor functions of individuals with severe neuromuscular disabilities. In this paper, a low-cost, single-channel, SSVEP based BCI system is implemented to control the motion of the wrist and the gripper of a robot arm. The SSVEP user commands are generated by focusing the user's gaze on a set of light-emitting diodes (LED) flickering at different frequencies. For the identification of user intent to generate control commands, a classification algorithm is proposed, which is based on Euclidean distance measurement between prominent peaks of the SSVEP Fast Fourier Transform (FFT) spectrum, and the fundamental and harmonic spectral content of stimulus frequency.","PeriodicalId":224327,"journal":{"name":"2021 IEEE Sensors Applications Symposium (SAS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129823225","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}

Here, simpler algorithms are used for shape or object detection. The scope of the present work is to even lower the complexity of the shape matching algorithm by converting a shape detection algorithm to an integer version and evaluate the results.

Such device is able to collect LoRa packets coming from the linear network and to encapsulate them in LoRaWAN packets transmitted to the remote server by means of standard LoRaWAN Gateways. The operation of the nodes is regulated by an ad-hoc routing protocol which aims at minimizing their active period, in order to reduce their power consumption increasing the overall system lifetime. Similarly, the synchronization of the nodes aims at increasing the robustness of the network reducing at minimum packet losses. The effectiveness of the proposed network architecture in terms of successful packet deliveries and reduction of active time is tested in different configurations, exploiting 2-node, 3-node and 4-node chains as well as adopting increasingly larger cycle periods. Results show that the proposed configuration ensures a noteworthy robustness in terms of packets delivery while maintaining the duty-cycling at levels that may guarantee long life times and autonomous operation to the overall infrastructure.","PeriodicalId":224327,"journal":{"name":"2021 IEEE Sensors Applications Symposium (SAS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128851502","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}
