The system uses a single sensor positioned on the head, close to the ear. The system recognizes noticeable gait features as irregular steps and the gait block (freezing of gait). Respect to other positions on the body, the headset has the maximum sensitivity to the trunk oscillations which patients make to get out of the block, increasing dramatically the risk of falls. The headset has also the advantage that it is easy to wear and the whole system can be contained in a single package. In fact, an audio device for auditory feedback to the patient can be integrated without any wireless/wired connection to the ear. The classification of those motion features is performed by an artificial neural network (ANN) and starts from the raw signals collected by the IMU. The ANN algorithm of recognition is extremely versatile and works for any individual gait features. The ANN allows robust and reliable detection of the targeted kinetic features and requires fast and light calculations. In this paper, it is presented the recognition of irregular steps, trunk oscillations and stop state obtained performing calculations out-board on a PC, without losing the generality of the method validity. The final headset system will be extremely energy efficient thanks to its compactness, to the fact that the ANN avoids computational energy wasting, and that the audio feedback does not require any wired/wireless connection. This affects positively the system performance in terms of power consumption and battery life (monitoring time).","PeriodicalId":395550,"journal":{"name":"2015 6th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125801448","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}

Many different solutions have been proposed in the past, which can be grouped into three main approaches: charge sensitive amplifiers, voltage-mode amplifiers and current-mode buffers. Here these architectures have been discussed and their limitations and advantages have been highlighted. The comparison has been carried out considering a simplified model of the detector and the classical expression of the time jitter. The influence of parasitic effects associated to the interconnections between the SiPM and the front-end electronics has also been analyzed and the corresponding limitations to the achievable timing performance of the different front-end styles have been considered, in order to find out more about the most suitable approach. To support the analysis, simulations of simple circuit implementations of the compared architectures have been carried out, under equal conditions. The results of the study show that the charge sensitive amplifier configuration results to be inefficient, due to bandwidth limitations, and that the best timing accuracy performance can be achieved by a current-mode approach, especially when the interconnection parasitics become relevant.","PeriodicalId":395550,"journal":{"name":"2015 6th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128172654","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 device is based on hydrogenated amorphous silicon p-type/intrinsic/n-type junction, fabricated on a glass substrate using thin-film technologies. The device structure is constituted by two series-connected amorphous silicon diodes: a blind one acting as dark reference and a photosensitive one. The signal measured at the output node of each element is equal to the difference of the current of the two diodes. This allows to minimize the temperature-dependent dark current contribution. The design of the photolithographic masks has been carefully carried out to pursue a perfect technological symmetry between the two diodes of the differential structure. Experimental data obtained by current-voltage characteristics show the correct operation of the individual diodes as well as the effectiveness of the differential structure to reject the common-mode signal induced by temperature variations. This feature makes the device a suitable candidate for analytical systems based on optical detection that involve thermal treatments.","PeriodicalId":395550,"journal":{"name":"2015 6th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126473090","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}
