to Senior Electronics Engineers &Managers  \nAugust 1972Volume 90,Number 2  \n'BIOBELT'SENDS LONG-DISTANCE ELECTROCARDIOGRAMS  \nSomeday soon a physician wil1 be able to take an electrocardiogramfrom a belt strapped to the patient—who may even be anastronaut orbiting earth.  \nUnder the NASA \"IMBLMS\"contract,a waist belt that holds thecomplex electronics needed to monitor the condition of a person'sheart and body temperature has been developed at LockheedMissiles &Space Co.,Sunnyvale,Cal.  \nLockheed also has invented a dry-skin,1.25-in.diameter electrodethat can be applied with a piece of double-backed tape,aspart of the program.Although dry electrodes have been usedbefore,Lockheed's is unique.An amplifier mounted on theelect rode gives superior performance compared to other drytypes of electrodes.  \nThe 2.5-in.wide,battery-powered lightweight belt is linked toa set of electrodes on the patient's skin and through anumbilicalto the system¹s command and data-display unit whichhas a separate power source.  \nThis biobelt detects the required signals emanating from thebody,amplifies the signals,sorts the proper signals from othersbroadcast by the body,and feeds the signals in sequence tothe command unit—al1 to provide a three-view electrocardiogramof the heart.  \nEar canal temperature signals also are fed to the command unitat its direction.  \nBiobelt changes the signals to binary form and transmits themto the command unit where they can be read on the command unit'sCRT from 10 up to 5,120 samples per second.The command unitdetermines the sample rate.  \nA safety feature to prevent electrical shock,the opticalcoupler is part of the system guaranteed to prevent up to  \nCopyright 1972,by Industrial Research Inc.,222 S.RiversideP1aza,Chicago,I11.60606.Reproduction prohibited withoutpermission.  \n\n| 2.5 kV from reaching the patient.Thus,the biobelt and patient  \u003Cbr>are electronically isolated from the powered command unit.  \u003Cbr>An additional safety feature is bui1t into the leads connecting  \u003Cbr>the body-Worn electrodes to the biobelt electronics,  This is  \u003Cbr>the Biomedical Ground Lead System(BGLS),invented earlier  \u003Cbr>by Lockheed.BGLS disconnects the electrodes from the electronics  \u003Cbr>if the current flowing in the leads rises above 100 μA.  \u003Cbr>With the aid of microcircuits,the be1t easily holds a package  \u003Cbr>that includes batteries,amplifiers,and plug-in points for  \u003Cbr>the electrodes.The complex electronics are needed to sort  \u003Cbr>out useful electronic signals from those normally emitted by  \u003Cbr>a person's body.  \u003Cbr>The dry-skin electrode eliminates the requirement of previously-  \u003Cbr>used electrodes that required cleaning and preparing the  \u003Cbr>patient's skin with chemicals prior to application.  \u003Cbr>The outer rim of the dry electrode is ceramic with a metal  \u003Cbr>center that makes direct contact with the skin.The electronics  \u003Cbr>on the electrode include resistors,capacitors,and a  \u003Cbr>preamplifier with high input impedance using a special  \u003Cbr>operational amplifier.  \u003Cbr>LEAP SECOND ocCURS IN JUNE  \u003Cbr>The first leap second in history occured June 30.At the  \u003Cbr>recommendation of the International Bureau of Time,an extra  \u003Cbr>second was inserted into the day of June 30,beginning at  \u003Cbr>23 hours 59 minutes 60 seconds UTC(Universal Coordinated  \u003Cbr>Time).The UTC clock at the National Bureau of Standards,  \u003Cbr>Boulder,Colo.,was set back one second.  \u003Cbr>The leap second also was incorporated into the broadcasts of  \u003Cbr>standard frequency and time stations WWV,WWVB,and WWVH  \u003Cbr>operated by the NBS Boulder Laboratories.  \u003Cbr>In the past,clocks were adjusted to our position in space  \u003Cbr>by adjusting the speeds of the clocks and by making step  \u003Cbr>adjustments of a fraction of a second.That method caused  \u003Cbr>confusion and was difficult to implement.  \u003Cbr>The new method,under international agreement,has been in
