This noninvasive method is based on the measurement of the intensity of an infrared-light beam, which penetrates the index finger. Digital techniques are used to produce the transmitted signal and to demodulate the received signal. Optical fibers are used to transfer the light to and from the sampling point. Frequency analysis of the peripheral volume pulse-wave signal is performed off-line. The power content in the harmonics of this pulse wave may be a useful measure of aging and vascular disease.","PeriodicalId":68878,"journal":{"name":"Journal of Measurement Science and Instrumentation","volume":"21 1","pages":"648-653 vol.1"},"PeriodicalIF":0.0,"publicationDate":"2001-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77914129","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}

However, the accuracy of the measurements is limited by small distortions in the grating lines of the disc, due either to damage or to manufacturing errors.

Unfortunately, most of these measuring systems are very specific, designed to be used in the hospital and costly. This paper describes a complete and versatile system which is designed for field use and can be tailored to several different measurement situations. The proposed system employs commercial sensors coupled to a versatile conditioning and acquisition board, which is designed to be connected to a conventional PC. A skeleton of the software which carries out the routine tasks (acquisition, storing, calibrations, and visualization) has been designed and installed on the PC. The skeleton can be easily adapted to the different applications, thus enabling the fast development of new clinical methodics. As an example, in this paper, an application is described that performs an oxygen/carbon dioxide analysis on a multi-breath basis and estimates the result uncertainty. The skeleton contains routines to save both results and raw data according to the DICOM standard format, so that the analyses can be easily shared among the different physicians involved in the patient's care.","PeriodicalId":68878,"journal":{"name":"Journal of Measurement Science and Instrumentation","volume":"6 1","pages":"27-31 vol.1"},"PeriodicalIF":0.0,"publicationDate":"2001-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76064838","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}

By using the friendly GUI from our implementation, users can adjust the period and amplitude of analog voltage waveforms with mouse clicks and drags. The data of the adjusted waveforms at the client computer can then be sent out to the server computer through the Internet. After this digital data is delivered to a server computer, the data is fed sequentially first into the ISA bus interface, then to the address decoder and finally to the D/A hardware, converting digital data into analog voltage waveforms, used as test signals. In this paper, we design this system by using the client-server model with the advantage of reliability, efficiency and adaptability and implement it with visual programming and very low cost interface circuits. The experimental results show that the bandwidth of the remote signal generator can reach 50 KHz, which is the speed limitation of the programmable peripheral interface chip 8255.","PeriodicalId":68878,"journal":{"name":"Journal of Measurement Science and Instrumentation","volume":"27 1","pages":"78-83 vol.1"},"PeriodicalIF":0.0,"publicationDate":"2001-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74773541","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}

For high volume production, optimized controllers are employed that typically have only limited computing resources.

Starting from the definition of standard deviation, we propose several modifications and obtain an easy-to-implement algorithm relying entirely on addition and shift operations. Numerical experiments verify the practicability of the approach. The proposed algorithm has already been successfully implemented in a capacitive angular speed sensor system for automotive applications.","PeriodicalId":68878,"journal":{"name":"Journal of Measurement Science and Instrumentation","volume":"33 1","pages":"465-468 vol.1"},"PeriodicalIF":0.0,"publicationDate":"2001-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/IMTC.2001.928861","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72463550","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}

In this paper the authors describe a travelling standard, which call be used for the calibration of many commercially available acquisition boards. By employing such a travelling standard, the calibration procedure can be remotely exercised by a calibration laboratory through the PC which hosts the board that has to be calibrated. In such a way the calibration results refer to environmental, software and hardware conditions that exactly match the board operating conditions. Furthermore, the board unavailability time is drastically reduced, with a consequent economic advantage for the board owner. The travelling standard embeds a micro-controller, which is responsible for the communication with the PC that hosts the board and for the board-stimulus generation, and a digital multimeter, which acts as a reference standard.","PeriodicalId":68878,"journal":{"name":"Journal of Measurement Science and Instrumentation","volume":"11 1","pages":"1625-1629 vol.3"},"PeriodicalIF":0.0,"publicationDate":"2001-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84602165","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}

However, the synaptic connections between neurons of the hilus and neurons of the granule cell layer are still debatable. In the present study, we utilized automated micromanipulation technique combined with visual image processing to analyze the synaptic connections between hilar mossy cells or mossy fibers, and granule cells or basket cells in the granule cell layer. The stereoscopic microscope image of the dentate gyrus of coronal slice in adult rat brain was converted into a binary image and the noises were reduced by median filter. The threshold for binary image was determined by the mean concentration and standard deviation calculated from the dentate gyrus. The area of the dentate gyrus is extended by region segmentation, and the two-valued image was constructed based on mean concentration and the standard deviation. Noises were further reduced by the dilation-erosion processing. This was matched with the template image made from a microscopic photo of cresyl violet-stained coronal section of the rat brain by parallel and rotation matching. A glass microelectrode was inserted into the apex of the dentate gyrus by the automated micromanipulation technique. Lipophilic fluorescent tracer DiI or DiD was injected into the hilus by a nanoinjector. Successful tracing of hilar neurons was observed by a confocal laser scan microscopy.","PeriodicalId":68878,"journal":{"name":"Journal of Measurement Science and Instrumentation","volume":"19 2 1","pages":"356-360 vol.1"},"PeriodicalIF":0.0,"publicationDate":"2001-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85415700","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}
