Patent number: 10545257Abstract: A device and method for material characterization are provided. In one aspect, the method includes detecting packets of radiation emanating from within or passing through one or more items of freight or baggage as a result of irradiation by incident radiation, using a plurality of detectors, each of the detectors being configured to produce an electrical pulse caused by the detected packets having a characteristic size or shape dependent on an energy of the packets. The method further includes processing each of the electrical pulses using one or more digital processors to determine the characteristic size or shape, generating a screening detector energy spectrum for each of the detectors of the energies of the packets detected, and measuring an effective atomic number Z of an unknown material associated with the one or more items of freight or baggage based on the screening detector energy spectra in comparison with calibration measurements.Type: GrantFiled: July 22, 2019Date of Patent: January 28, 2020Assignee: Southern Innovation International Pty LtdInventors: Paul Andrew Basil Scoullar, Christopher Charles McLean, Shane Michael Tonissen, Syed Khusro Saleem, Brendan Allman

Patent number: 6983030Abstract: An approach for processing data received from a communications channel in finite precision arithmetic applications generally involves equalizing received data in the time domain prior to demodulation using finite impulse response (FIR) filtering. FIR coefficients used in FIR filtering are selected to minimize SNR degradation attributable to ISI and roundoff errors due to finite precision arithmetic, thereby maximizing channel capacity. The approach considers the communications channel noise attributable to crosstalk, white noise and analog to digital converter quantization noise, ISI attributable to failure of the equalizer coefficients to completely eliminate ISI, round off noise due to the use of finite precision arithmetic in the equalizer and roundoff noise due to the use of finite precision arithmetic in the FFT algorithm.Type: GrantFiled: January 2, 2001Date of Patent: January 3, 2006Assignee: Bandspeed, Inc.Inventors: Andrew Storm, Shane Michael Tonissen, Efstratios Skafidas

Patent number: 6804313Abstract: An approach for processing data received from a communications channel generally involves equalizing received data in the time domain prior to demodulation by an approach that incorporates mitigation of interference. Oversampling of the received signal provides improved equalization performance and mitigation of interference, such as crosstalk. A receiver oversamples a received signal and splits the signal into a set of observation sequences. The set of observation sequences are processed to provide an estimate of the input to the communications channel, while providing at least partial rejection of any interfering signal. Exact knowledge of the parameters of the interference signal is not required.Type: GrantFiled: January 2, 2001Date of Patent: October 12, 2004Assignee: Bandspeed, Inc.Inventors: Efstratios Skafidas, Shane Michael Tonissen

Patent number: 6295326Abstract: A computer-implemented approach for reducing distortion in digital communications systems generally involves obtaining an optimal estimation of the original data using a Kalman filter with an increased length state to remove substantially all ISI in the time domain. The use of an increased length state in the Kalman filter provides a more accurate estimate of the transmitted data with relatively little additional computational cost. Subsequent equalization may also be performed in the frequency domain to correct any residual amplitude and phase distortion.Type: GrantFiled: March 1, 2000Date of Patent: September 25, 2001Assignee: Bandspeed, Inc.Inventors: Shane Michael Tonissen, Efstratios Skafidas, Andrew Logothetis
