    A completely transistorized radio transmitter and a receiving system are described operating at 104 mc. The weight of the transmitter is under two pounds without the use of miniature parts. Design is for transmission of up to ten channels with bandwidths of 250 and 1000 cps. The channel reported has a carrier frequency of 2100 cps and was tested for EKG recording. Satisfactory calibrated records w... View full abstract»

    The minimum specimen exposure at television scanning rates required to yield pictures with acceptable signal-to-noise ratio and the best resolution optically attainable is computed for flying-spot, image-orthicon, and vidicon television microscopes for the ultraviolet. This exposure is found to be slightly less for the flying-spot microscope than for the image-orthicon microscope. For microscopes ... View full abstract»

  • An Apparatus for Recording Heartbeats of a Fetus

    Obstetricians have expressed a wish for a simple and low-cost apparatus for monitoring the heartbeats of a fetus before and during birth. This paper describes a special type of amplifier that was built to satisfy this requirement. By transposing the low frequencies of the heartbeats to a higher-frequency region, some of the difficulties that would otherwise be encountered are avoided. This makes t... View full abstract»

  • The Transient Response of the Human Operator

    In this paper, the authors have derived the equations representing the dynamic response of a human operator in the performance of a particular task. These equations were plotted and compared to the recordings of the actual response and show agreement well within experimental error. Possible applications of this method are suggested in the fields of servomechanisms, medicine, physiology, and psycho... View full abstract»

  • Analysis of Heart Murmurs by Electronics

    Publication Year: 1958 , Page(s): 72 - 75
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (766 KB)  

    This paper gives a brief survey of early and current work in the application of audio-frequency amplifiers, equipped with filters, to the diagnosis of abnormal heart conditions, and for use as teaching aids in medical schools. The possible application of a gating technique, i.e., filtering in time instead of in frequency, is discussed, and a description is given of some circuits which have been us... View full abstract»

  • A Servo Operated Respirator for Premature Infants

    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (2997 KB)  

    This paper describes a machine for the application of artificial respiration to infants. The machine will operate automatically as a respiration amplifier when any spontaneous breathing is present, or as a forced respirator when there is no natural breathing. The respiratory cycle is induced by the external application of a negative pressure to the body and all significant variables may be indepen... View full abstract»

  • Theory of measurement of blood flow by dye dilution technique

    Publication Year: 1958 , Page(s): 82 - 88
    Cited by:  Papers (1)

    The general mathematical theory of measurement of blood flow by dye dilution techniques is discussed. The mathematical procedure for handling the recirculation problem is described, and it is shown that, in general, sampling of concentration at a single point is not sufficient to uniquely determine both the volume and flow in a vascular bed. The more basic problem of synthesizing a mathematical mo... View full abstract»

  • Automatic Counting of Bacterial Cultures- A New Machine

    Publication Year: 1958 , Page(s): 89 - 92
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (2424 KB)  

    A machine which solves the general problem of counting randomly placed objects of varying size on a surface is briefly described. It is able to accomplish this task by systematic discard of information. It is essentially a scanning device with a ``memory'' in the form of a quartz ultrasonic delay line. A ``decision-making'' element controls the discard of information and directs the counting actio... View full abstract»
