Abstract: In a presently preferred embodiment of the invention, a three-dimensional scene is reproduced on a specialized light display which offers full multiviewpoint capability and auto-stereoscopic views. The displayed image is produced using a set of M two-dimensional images of the scene collected at a set of distinct spatial locations. These M two-dimensional images are processed through a specialized mathematical encoding scheme to obtain a set of N×K display-excitation electrical-input signals, where K is the number of pixels in the display, and N≦M is the number of individual light-radiating elements within one pixel. The display is thus comprised of a total of N×K light-radiating elements. Each of the K pixels is adapted for control of their associated radiance patterns. The display is connected for response to the set of N×K display-excitation electrical-input signals.

Abstract: Non-invasive quantitative in-vivo electromagnetic evaluation of bone is performed by subjecting bone to an electrical excitation waveform supplied to a single magnetic field coil near the skin of a bony member, and involving a repetitive finite duration signal consisting of plural frequencies that are in the range 0 Hz-200 MHz. Signal-processing of a bone-current response signal and a bone-voltage response signal is operative to sequentially average the most recently received given number of successive bone-current and bone-voltage response signals to obtain an averaged per-pulse bone-current signal and an averaged per-pulse bone-voltage signal, and to produce their associated Fourier transforms. These Fourier transforms are further processed to obtain the inductively determined frequency-dependent bone-admittance function.

Abstract: Non-invasive quantitative in-vivo electromagnetic evaluation of bone is performed by subjecting bone to an electrical excitation wave-form supplied to a pair of electrodes on opposite sides of a bony member, and involving a repetitive finite duration signal consisting of plural frequencies that are in the range 0 Hz-200 MHz. Signal-processing of a bone-current response signal and a bone-voltage response signal is operative to sequentially average the most recently received given number of successive bone-current and bone-voltage response signals to obtain an averaged per-pulse bone-current signal and an averaged per-pulse bone-voltage signal, and to produce their associated Fourier transforms.

Abstract: An unknown object is non-destructively and quantitatively evaluated for three-dimensional spatial distribution of a set of material constitutive parameters, using a multi-element array-source transducer and a multi-element array-detector transducer in spaced, mutually facing relation. The array-source transducer exposes the array-detector transducer to a set of source-field patterns pursuant to a set of electrical input signals. Either a known object or an unknown object positioned between these transducers will be the cause of scattering, thus presenting a scattered-field pattern to the array detector transducer, for each pattern of the set of source-field patterns. A computer, a signal processor and a neural network operate from detector response to each set of scattered-field patterns, in each of two modes.

Abstract: An unknown object is non-destructively and quantitatively evaluated for three-dimensional spatial distribution of a set of material constitutive parameters of the unknown object, using a multi-element array-source transducer and a multi-element array-detector transducer located near the unknown object. The array-source transducer exposes the array-detector transducer to a set of source-field patterns pursuant to a set of electrical input signals. An unknown object located near these transducers will be the cause of scattering, thus presenting a scattered-field pattern to the array detector transducer, for each pattern of the set of source-field patterns. In a related computation, a set of training signals is determined by evaluating on a computer the scattered field from a set of computer simulated training objects. A computer, a signal processor and a neural network operate from detector response to the computer simulated and unknown object scattered-field patterns, in each of two modes.
