    The myoelectric activity occurring within the intestine is exceedingly complex and existing analytic techniques are tedious and laborious. An automated system has been developed to perform computerized analysis of electrical spike burst activity recorded from multiple small intestinal electrodes. This software data analysis system was developed to 1) recognize individual spike bursts occurring in ... View full abstract»

    Cardiac X-ray computed tomography (CT) has been limited due to scanning times which are considerably longer (1 s) than required to resolve the beating heart (0.1 s). The otherwise attractive convolution-backprojection algorithm is not suited for CT image reconstruction from measurements comprising an incomplete set of projection data. In this paper, an iterative reconstruction-reprojection (IRR) a... View full abstract»

    A mathematical model for the occurrence of nonoverlapping pulse-shaped waveforms corrupted with colored Gaussian noise is considered for the purpose of QRS detection. The number of waveforms, the arrival times, amplitudes, and widths are regarded as random variables. The joint MAP estimation of all the unknown quantities consists of linear filtering followed by an optimization procedure. A class o... View full abstract»

    A new type of carbon electrode is introduced. The electrode consists of a bundle of carbon fibers, each fiber having a diameter of approximately 8 jim. In contrast to most electrodes, this electrode is flexible. The fabrication of the electrode is described, and a method is given to determine the apparent stimulating area. View full abstract»

  • A Battery-Powered Digital Modem for Telephone Transmission of ECG Data

    Publication Year: 1982, Page(s):355 - 359
    Cited by:  Papers (2)  |  Patents (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2072 KB)

    We present the design of a battery-powered digital modem for transmitting ECG signals. It operates from a 5-V battery supply, uses a coil or acoustic coupler for a telephone interface, and consumes only 30 mW during transmission. We show error rates comparable to regular stand-alone modems, well within the acceptable limit of 1 bit per 100 kbits transmitted at a transmission speed of 300 Bd. View full abstract»

    The sequence of excitation of cardiac muscles is greatly affected by any abnormality in the conduction system of the heart. Epicardial mapping for the measurement of activation time at different points is helpful for the diagnosis of such abnormalities. For the measurement of activation time at different points of the epicardial surface, a number of sophisticated instruments, including microcomput... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (863 KB)

    A circuit for contact impedance monitoring in ECG is presented. An ac current in the same frequency band as the ECG signal is used for the measurement. This makes the measurement independent of polarization potentials and gives the correct weight to the impedances in the skin-to-electrode junction. The measurement of the contact impedance is made continuously during ECG monitoring and causes no in... View full abstract»

    Static responses of human accommodation (focusing) and vergence (eye-turn) are controlled by two separate feedback control systems. The two systems also interact so that each is capable of producing an isolated motor response in the other. When both systems operate together, as in normal binocular movements, they must share control in some manner. A recently proposed static oculomotor control theo... View full abstract»

    The development of a new noninvasive computerized technique for producing simultaneous lateral, anterior-posterior, and transverse views of the carotid bifurcation for the diagnosis of occlusive disease is described. These multiplanar views have been used to detect 40 percent diameter reductions with a sensitivity of 100 percent and a specificity of 85 percent in 94 comparisons with vessel X-rays.

    An idealized model for a circular electrosurgical dispersive electrode is analyzed by solving Laplace's equation for the potential distribution. The resulting analytical solution shows the origin of the perimetrical burn problem, and, simultaneously, points the way toward improved electrode designs. One possible improved electrode design, a segmented circular electrode in which the annular segment... View full abstract»

    Analytically solvable distributed equivalent-circuit models have been developed for circular electrosurgical dispersive electrodes which are either resistively or capacitively coupled to the body. Calculations based on these models show that for either electrode type it is possible to define a characteristic length, the magnitude of which governs the current distribution under the electrode. The w... View full abstract»
