A set of equations derived to describe the optics of highly scattering materials are explained, extended, and applied to the problem of in vitro and in vivo measurement of the relative oxygen saturation of nonhemolyzed blood. Fundamental absorption and scattering coefficients are described and related to the absorption coefficient of hemolyzed blood. Diffusion equations for light photons are used ... View full abstract»

• An Acoustic Bridge for Measuring the Static and Dynamic Impedance of the Eardrum

| | PDF (2570 KB)

An acoustic impedance bridge is described that is capable of measuring the input impedance of the human ear in the frequency range of 250 to 1250 Hz, with an accuracy of 3 degrees and 5 percent in phase and magnitude, respectively. In addition to static impedance, the bridge measures and records both in-phase and quadrature components (re an arbitrary reference) of changes in the ear's impedance d... View full abstract»

• Detection of Weak Foetal Electrocardiograms by Autocorrelation and Crosscorrelation of Envelopes

There is no general rule that abdominally recorded electrocardiograms of pregnant women reveal visible foetal R waves. In some stages of pregnancy the foetal electrocardiogram (FECG) is even smaller than a slightly noisy baseline. It is also possible that large muscle disturbance (electromyogram) makes the FECG invisible. On the one hand, there is a redundancy of information in the form of a long ... View full abstract»

• Low-Frequency Piezoelectric Energy Conversion for an Intrathoracic Artificial Heart

Publication Year: 1968, Page(s):24 - 33

| | PDF (3266 KB)

The present paper is concerned with an evaluation of a piezoelectric energy conversion system in which two columns of piezoelectric ceramic disks are excited axially by means of thin metallic shims stacked alternately with the disks. Mechanical energy output is extracted through the expansion and contraction of the Columns. The treatment is based upon the equivalent circuit approach first suggeste... View full abstract»

• A Study of Power Spectra Analysis of Normal Finger Tremors

Publication Year: 1968, Page(s):33 - 45
Cited by:  Papers (17)  |  Patents (1)
| | PDF (5155 KB)

Measurements of normal,' neuromuscular finger tremor acceleration in healthy adults were made and then analyzed by power spectra and correlation techniques. These techniques from random-signal analysis offer objective methods by which tremors may be described and compared quantitatively. Measurements of this type may provide useful information in evaluating surgical and medical treatments of Par... View full abstract»

• A Continuous Multichannel Automatic Curve Reader

Publication Year: 1968, Page(s):46 - 53
Cited by:  Papers (5)
| | PDF (2579 KB)

Details of construction and characteristics of performance for a multichannel analog curve reader are described. This system is intended primarily for automatic transcription of bioelectric-data recordings such as electroencephalograms, and employs the principle of phase-modulated analog sampling. It utilizes electro-encephalographs, polygraphs, or similar devices through which the original record... View full abstract»

• Computer Analyses of Clinical Electroencephalographic Ink Tracings with the Aid of a High-Speed Automatic Curve Reader

Publication Year: 1968, Page(s):54 - 61
Cited by:  Papers (7)
| | PDF (7595 KB)

Computer analyses of clinical electroencephalographic (EEG) ink tracings, which were reconverted to their electrical form with the aid of a newly developed multichannel automatic curve reader, are illustrated. On-line and off-line (via the intermediary of a magnetic tape recording) analyses by a variety of methods (frequency analysis, autocorrelation and crosscorrelation, and averaging of EEG resp...
