    With the subject exposed to an alternating magnetic field, eye position may be accurately recorded from the voltage generated in a coil of wire embedded in a scleral contact lens worn by the subject. Using two magnetic fields in quadrature phase and two coils on the lens, one may measure horizontal, vertical and torsional eye movements simultaneously. The instrument described has an accuracy and l... View full abstract»

    The objective of the research was to develop a transducer to measure arterial blood pressure. It was required that the transducer provide a continuous measure of blood pressure, that it not encumber the subject and that it not require cannulation. Two basic techniques were investigated both analytically and experimentally. First, an indirect measurement of blood pressure based on arterial deflecti... View full abstract»

    Automatic interpretation of electrocardiograms is a particular example of the application of digital computers to medical diagnosis; this paper describes our experience with a new approach involving pattern recognition techniques. The program employs a multiple adaptive matched filter system with a variety of normalization, weighting, comparison, decision, modification, and adapting operations. Th... View full abstract»

    The paper reviews the application of image theory to the problem of a current dipole in a homogeneous conducting medium where the boundary is a plane or circular cylinder, and shows how the technique applies to the case of a radial dipole in a spherical volume. The use of images for arbitrary shaped volumes is then considered. A rough criterion is developed and the approximation checked for the ca... View full abstract»

    The Helmholtz reciprocity theorem for currents in an inhomogeneous conducting media is put into a useful form for the solution of problems such as arise in electrocardiography. Several examples are considered which lead to known results and which illustrate the application of the method. View full abstract»

    The potentials generated by a live turtle (pseudemys) heart at the center of a spherical electrolytic tank were measured at surface points. Using a truncated multipole expansion, the dipole and quadrupole coefficients were determined from the resultant set of simultaneous equations at intervals over the QRS period. The measurement technique was checked using known artificial sources; a rough check... View full abstract»

    The theoretical basis for information retrieval and analysis in vector electrocardiography is examined with a view to establishing fundamental limitations on commonly used clinical techniques. The basis for equivalent heart generators is specified and relationships between them are analyzed. An "ideal" lead system is defined and related to practical clinical schemes. Limitations of an "ideal" lead... View full abstract»

    By taking advantage of readily available industrial devices, used in conjunction with a simple auxiliary circuit, an efficient inexpensive blood-flow measuring system can be obtained. As a further advantage, the preamplifier and demodulator-recorder may be detached and used for other purposes. Flow recordings obtained with this system appear to equal or better recordings obtained with commercial i... View full abstract»

    The term biological clock is used to designate the phenomenon, displayed by organisms, of pacing activity in a cyclic manner related to environment. Many nocturnal animals, for example, are capable of entraining the onset of their activity with the light-to-dark transition in a periodic light-dark regime in which the period or ratio of light to darkness varies widely. This paper presents the devel... View full abstract»

    A simple and versatile microspectrofluorometer is described together with suitable electronic circuits for single-differential-or double-aperture operation. The apparatus is suitable for measuring oxidation-reduction states of mitochondrial and cytoplasmic pyridine nucleotide in various organs with apertures ranging from 15 microns up to a few millimeters. Suitable optical and electronic component... View full abstract»
