Modeling human open-loop tracking behavior
Proceedings of the 19th Annual International Conference of the IEEE Engineering in Medicine and Biology Society. 'Magnificent Milestones and Emerging Opportunities in Medical Engineering' (Cat. No.97CH36136) - Tập 1 - Trang 836-839 vol.1
P.R. Davidson, R.D. Jones, J.H. Andreae, H.R. Sirisena
A nonlinear generalization of the Adaptive Model Theory, nAMT, is compared with human open-loop tracking data across the same range of conditions. The resulting simulations produced effects that mirrored the closed- and open-loop characteristics of the experimental response trajectories. This supports the use of an internal feedback loop for the inversion of external systems in the nAMT model. Oth...... hiện toàn bộ

Heart transplantation-spectral and bispectral analysis
Proceedings of the 19th Annual International Conference of the IEEE Engineering in Medicine and Biology Society. 'Magnificent Milestones and Emerging Opportunities in Medical Engineering' (Cat. No.97CH36136) - Tập 1 - Trang 515-518 vol.1

Heart transplantation offers a unique view into an unusual cardiovascular system, with a denervated heart. We investigate noninvasively the compensatory cardiovascular control mechanisms, which develop following transplant. ECG, continuous blood pressure and respiration are recorded in supine position and during transition to standing, and analyzed in time and frequency domains. 25 recordings were...... hiện toàn bộ

A spike triggered averaging technique for high resolution assessment of single motor unit conduction velocity changes during fatiguing voluntary contractions
Proceedings of the 19th Annual International Conference of the IEEE Engineering in Medicine and Biology Society. 'Magnificent Milestones and Emerging Opportunities in Medical Engineering' (Cat. No.97CH36136) - Tập 2 - Trang 1097-1100 vol.2

In this paper we propose an improved spike triggered averaging technique for the assessment of control properties and conduction velocity (CV) of single motor units (MUs) during voluntary sub-maximal muscle contractions. The method is based on the detection of multi-channel surface EMG signals (with linear electrode arrays) and intramuscular recorded single MU action potentials (MUAPs). Intramuscu...... hiện toàn bộ

Effect of calcium-activated chloride current blockade on the delayed after depolarizations. Simulation study
Proceedings of the 19th Annual International Conference of the IEEE Engineering in Medicine and Biology Society. 'Magnificent Milestones and Emerging Opportunities in Medical Engineering' (Cat. No.97CH36136) - Tập 1 - Trang 19-22 vol.1
J. Gomis-Tena, J. Saiz
High intracellular calcium conditions cause a calcium-activated transient inward current (I/sub ti/) that can provoke oscillations in membrane potential called delayed after depolarizations (DAD). The current I/sub ti/ comprises of the sodium-calcium exchange current (I/sub NaCa/) and the calcium-activated chloride current (I/sub NaCa/). Lindblad, Murphey, Clark and Giles (1996) developed a mathem...... hiện toàn bộ

Design of a prototype for dynamic electrocardiography monitoring using GSM technology: GSM-Holter
Proceedings of the 19th Annual International Conference of the IEEE Engineering in Medicine and Biology Society. 'Magnificent Milestones and Emerging Opportunities in Medical Engineering' (Cat. No.97CH36136) - Tập 4 - Trang 3956-3959 vol.4
J.M. Guillen, J. Millet, A. Cebrian
Monitoring patients with serious cardiovascular problems is invaluable in preventing further crises and achieving a faster, more effective attention. To this end, noninvasive cardiologic tests such as dynamic electrocardiography (e.g., Holter) have proven useful in clinical practice. The present document puts forward a novel Holter system that benefits from the GSM mobile telephony standard widesp...... hiện toàn bộ

Robust computer-assisted laser treatment using real-time retinal tracking
Proceedings of the 19th Annual International Conference of the IEEE Engineering in Medicine and Biology Society. 'Magnificent Milestones and Emerging Opportunities in Medical Engineering' (Cat. No.97CH36136) - Tập 3 - Trang 2499-2502 vol.3

We propose a new computerized system to accurately guide laser shots to the diseased areas within the retina based on predetermined treatment planning. The proposed system consists of a fundus camera interfaced to a computer that allows real-time capturing and processing of a sequence of images at video frame rates. The first image in the sequence is used as a reference for manual treatment planni...... hiện toàn bộ

Non-invasive measurement of diaphragmatic contraction timing in dogs
Proceedings of the 19th Annual International Conference of the IEEE Engineering in Medicine and Biology Society. 'Magnificent Milestones and Emerging Opportunities in Medical Engineering' (Cat. No.97CH36136) - Tập 1 - Trang 437-440 vol.1

The movement of thoracic cage (TM) measured with a piezoelectric contact sensor placed on the costal wall is presented in this work as a new non-invasive technique for diaphragmatic contraction period (CP) monitoring. The relationship between CP estimated with this technique is compared with estimations done with other respiratory signals commonly employed for physiological research studies: diaph...... hiện toàn bộ

Properties of auditory temporal integration revealed by mismatch negativity
Proceedings of the 19th Annual International Conference of the IEEE Engineering in Medicine and Biology Society. 'Magnificent Milestones and Emerging Opportunities in Medical Engineering' (Cat. No.97CH36136) - Tập 1 - Trang 1002-1005 vol.1

The mismatch negativity (MMN), a component of event-related potentials (ERP), was recorded to investigate the properties of the storage of auditory temporal sequences in the sensory memory. First, the MMN elicited by the infrequent change in a pair of closely spaced tones was evaluated. In ignored condition, it was shown that the MMN was elicited only when the total duration of the tone pair was l...... hiện toàn bộ

Micromachined devices with substrate-integrated electrodes are the key component in implantable microdevices for recording neuronal signals or stimulating nerves. For basic investigations in central- and partially in peripheral-nerve structures, silicon based shaft electrodes have established as standard multichannel device. In this paper, we present polyimide based multichannel shaft electrodes w...... hiện toàn bộ
