摘要： This invention provides an acoustic imaging device in which a large number of transducers (10) are spaced less than half acoustic wavelength apart on a circle surrounding an object (9) to be imaged. A signal generator (26) generates discrete acoustic frequencies in the range of 100 kHz to 1.5 MHz. Multiplexer systems (1-8) are provided to permit each transducer, one at a time, to broadcast a signal while the broadcast signal is detected by the other transducers. Electronic equipment records the detected signal and from the recorded information phase and amplitude data is calculated with respect to each transducer location. A computer (38) programmed with an algorithm computes images of slices through the object using the phase and amplitude data. We utilize single frequency, steady-state acoustic signals which enables the accurate determination of the phase and amplitude of the acoustic signals at each receiver transducer. Finally, in order to reduce the data acquisition time and reduce motion artifacts, we utilize acoustic signals comprised of a plurality of discrete identifiable frequencies each frequency providing an image of the medium.

摘要： An acoustic imaging device is disclosed which utilizes mathematical inversion of scattered acoustic wave information to produce an image. A preferred embodiment of the device consists of a ring of acoustic transducers (10.1-10.N) which encircle a medium (12) to be imaged. The medium is sequentially insonified by each transducer with subsequent reception of the scattered waves by the remaining transducers. Explicit mathematical inversion of the scattered wave data using a remap algorithm results in a two-dimensional map of the scattering potential of the medium. Sound speed and density maps can be obtained from a map of the scattering potential. The device is utilizable for imaging of human tissue in vivo and in vitro, and for nondestructive evaluation of materials.

摘要： A fall arrest system has a top anchorage bracket (1), a bottom anchorage bracket (2) and a cable (3) between the brackets. Fixture ends (12, 22) of the brackets carry bosses (13, 23) in their bottom and top edges (14, 24) respectively. Cable tension pulls the distal ends of the brackets towards each other about the bolts B and the bosses react with the corner of the pylon. The bracket end (15) is dimensioned such that in the event of a fall and loading of the cable, the bracket (1) deforms plastically, peeling away from the face F. The bottom anchorage bracket (2) has an arm (25) with a bore for a clamp bolt (31), carrying a load transfer bracket (32) and a clamp nut (34). The bolt is engaged in a slot (35) in a slotted limb (36) of the bracket (32). Above the limb, the load transfer bracket (32) is integrally connected via a thin tongue (37) to a sleeve (38) locating the end of the cable. The cable (3) extends through the sleeve to a swaged on collar (40). A tensioning device is used to draw down the limb (36) and tension the cable, whereupon the brackets (2) and (32) are clamped together.
