Title: Measuring Number of Turns of a Toroidal Coil
IPC: G01R31/72
Filed: 1979-04-17
Abstract: An energising coil 3 and a reference coil 6 each having a known number of turns are disposed about the toroidal core 1 and a voltage is induced across the reference coil and the coil under test by a voltage applied across the energising coil. A measure of the voltage induced across the reference coil 6 is derived and compared with a derived measure of the voltage induced across the coil under test 2 in a digital voltmeter 9 to derive a measure of the ratio of the number of turns of the coil under test to the number of turns of the reference coil. In this manner, errors due to voltage drop across the energising coil and associated iron losses are avoided. It is preferred to amplify the voltage induced across the reference coil by a first amplification factor 7, to amplify the voltage induced across the coil under test by a second amplification factor 10 and to make the product of the ratio of the first and second amplification factors and the number of turns of the reference coil equal to the response constant of the digital voltmeter so that the reading obtained directly represents the number of turns of the coil under test. <IMAGE>

Title: Cameras with rangefinders
IPC: G03B13/36
Filed: 1979-04-19
Abstract: In a camera having a rangefinder (26) an indication is given or shutter actuation is inhibited if the distance of the subject sensed by the rangefinder is too close for correct focus or is too close or too far for proper exposure with flash illumination. As shown, an adjustable focus lens (14) is driven towards a position of correct focus in response to a signal derived from the rangefinder and a signal representing the lens position. Switches (50, 51) operated by the movement of the lens mount initiate the said indication preferably by means of lamps (84A, 88A, Figure 6 not shown), and the inhibition of shutter actuation. Alternatively, the count in a counter receiving a train of pulses from the rangefinder may be used as a direct indication of a subject distance outside an acceptable range. In another form, the rangefinder signal defines a time interval and circuits within the camera define minimum and maximum time intervals within which the rangefinder signal must lie if the subject is at an acceptable distance. <IMAGE>

Title: Apparatus for Detecting, Localizing and Quantifying Coronary Stenoses from the Body Surface using Gamma-ray-emitting Particles and Coded Apertures
IPC: A61B5/0275
Filed: 1981-03-20
Abstract: The extent, location, and severity of stenotic atherosclerotic lesions in the coronary arteries are determined by intravenous injection into the circulating blood of a number of small, discrete gamma-ray-emitting particles and by tracking the particles in three dimensions in the region of the heart using suitable gamma detectors (29), which have coded apertures 23 including regions having different transmission factors for the radiation and which are disposed external to the patient's chest. The resolution and counting rates of the gamma detectors permit the sequence of positions of each particle to be recorded as a function of time as each particle flows through a coronary vessel. Data analysis of these recordings of particle position provides information about the velocity of blood flow through the course of each coronary artery. This information is used to determine the course of the vessel of interest and the extent, severity, and location of stenotic lesions therealong. <IMAGE>

Title: Servo system for positioning a movable transducing head assembly
Inventor: BAKER BILLY RICHARD
IPC: G11B5/588
Filed: 1982-08-26
Abstract: A method and apparatus for accurately positioning a transducing means along a desired path for recording parallel tracks of information being transmitted at varying rates. The apparatus also accurately follows the tracks during reproducing at various tape transport speeds. In a helical scan machine, the rotary scanner includes a movable support carrying the transducing means. The support responds to electrical signals to move the transducing means in opposite directions from a datum position, the movement being generally transverse to the direction of the sets of tracks. The transverse position of the transducing means is sensed to provide position data which are stored and used to produce signals for positioning the transducing means either to record a set of tracks along a desired path or reproduce from the tracks and, during recording, to record additional sets of tracks subsequent to the completion of the preceding set of tracks along paths parallel to the selected path, the selected path being determined as a function of the speed and direction of transport of the tape. <IMAGE>
