Title: Optical intersatellite communications system
Inventor: KWONG ALICE S-Y
IPC: H04B10/118
Filed: 1999-03-18
Abstract: An intersatellite optical communication system utilizing a non-coherent differential binary phase shift keyed modulation for digitizing uplinked RF signals for use both within the satellite and for within a network of satellites. The modulated and digitized signal is transmitted from a transmitting end to a receiving end. At the receiving end, the received signal is split into two signals with one signal being delayed by one bit of the bit rate. Recombining the delayed and non-delayed split signal results in an interference pattern that eases the process of recovering the original signal.

Patent CA-2272246-A1 (CA)
Inventor: YANG JIAN
IPC: H04L25/49
Filed: 1999-05-18
Abstract: A receiver has a dual mode of operation - a carrierless amplitude modulation/phase modulation (CAP) mode and a quadrature amplitude modulation (QAM) mode - yet only requires a single equalizer structure for both the CAP  mode of operation and the QAM mode of operation during blind start-up. The receiver uses the same blind equalization updating algorithm independent of the type of received signal for converging the equalizer structure. The blind equalization updating algorithm incorporates a constant R, whose value is a function of the type of received signal, e.g., a QAM signal or a CAP signal. The type of received signal is determined as a function of the in-phase component of the mean-squared error, E[e2 n].

Title: Lung surface area analysis using computed tomography
Inventor: HOGG JAMES C
IPC: G06T7/60
Filed: 1999-06-11
Abstract: A computer-implementable method for estimating the surface area to volume ratio and the surface area of a lung based on x-ray attenuation data obtained from a computed tomography (CT) scan of the hung is disclosed. The method includes obtaining a plurality of CT images that include a lung image from a plurality of subjects. Each of the resulting CT images is displayed such that an x-ray attenuation value is associated with each pixel. Thereafter the lung image is extracted from the CT image. Theft, the volume of each lung is calculated based on the plurality of lung images extracted from the plurality of CT images. Also, the volume-of-gas to weight-of-tissue ratio for all of the pixels included in each of the lung images is calculated using the x-ray attenuation value associated with the pixel. The pixel ratio values are used to determine the median volume-of-gas to weight-of tissue ratio for all the pixels included in all the lung images for each lung. Then the surface area to volume ratio of each lung is determined using quantitative histology. Thereafter, the surface area to volume ratio versus the median volume-of-gas to weight-of-tissue ratio is plotted for each lung. The plot is used to determine a best-fit prediction equation that correlates the surface area to volume ratio to the volume-of-gas to weight-of-tissue ratio. The equation is used to estimate the surface area to volume ratio and the surface area of a new lung based on a CT scan of that lung.

The system creates a substantially similar print on the second printer system by using means for creating a replacement image characteristic data file for generating a second substantially similar print using the second printer system. The replacement image characteristic data file provides , instead of the original absolute value, a second absolute value.
