Filed: 1998-02-16
Granted: 2003-09-02
Abstract: Modular endoluminal stent-grafts include at least two different sized stent- grafts which are deployed one within the other. According to one embodiment of the invention, a first stent-graft is provided having a flared end which is expandable to a first diameter and a midsection which is expandable to a second diameter smaller than the first diameter. A second stent-graft is also provided having an end which is expandable to a diameter  which engages the midsection of the first stent-graft. The first embodiment of the invention i s deployed by expanding the first stent-graft such that its flared end engages a large diameter vessel, then expanding the second stent-graft inside the midsection of the first stent graft and inside a small diameter vessel such that the second stent graft engages the small diameter vessel and the midsection of the first stent-graft. According to a second embodiment of the  invention, the midsection of the first stent-graft is reinforced with a flexible member to restrict the midsection from ballooning. According to other aspects of the invention, the  first stent-graft is provided with two flared ends and the second stent graft is provided with or  without flared ends. According to still another embodiment of the invention, three or more stent-grafts of different expanded diameter are deployed one within the other.
Patent CA-2230340-C (CA)
Title: Burst demodulator
Inventor: IEMURA TAKAYA
IPC: H04L7/08
Filed: 1998-02-24
Granted: 2001-02-06
Abstract: A burst demodulator prevents transmission efficiency from being lowered, and a dynamic range of an input strength from being narrowed, by providing a stable frame signal even if the reaction is rapid against the input and the input strength is low.  A logarithm amplifier outputs an electric power strength of a modulated input signal as a logarithm value, and an integrator smooths the output of the logarithm amplifier and outputs the smoothed output as an RSSI.  The comparator compares the RSSI with the appropriate reference value REF while including some margin within the noise level, and outputs the frame signal of an 'LO' state when the RSSI is lower than the REF, that is, during the non-signal zone, of an 'HI' state when the RSSI is higher than the REF, that is, during the signal zone.          The period of the comparator output continuously remaining in the 'LO' state cannot exceed one clock period even if the comparator output flutters within one time slot.  When the comparator output is fixed to the 'LO' state and the CLK is input by two clocks, the output of the counter becomes the 'HI' state, whereby the output of the counter and the OR computing element mask the CLK, which fixes the counter output to the 'HI' state until the comparator output becomes the 'HI' state again.

Abstract: In a multi-channel demodulator, a detection-transition sample estimation scheme classifies samples as left (L) or right (R) of a reference position within a symbol interval (110), or before (B) or after (A) a transition between symbols (120). When a sample is classified as L or B, the classification of the next sample is forced to R or A, respectively. A memory is provided for storing the contents of various registers when switching to processing of a different channel, and for retrieving from the memory stored data corresponding to previous processing of the different channel. Data read from the memory is written to a register downstream of the register from which it was taken when written to the memory. The read cycle of the memory is extended to ensure that a clock is available to load the data from memory into the downstream register after switching to the new channel.

Abstract: A computer graphics system generates a three-dimensional model of an object in an interactive manner under control of an operator. An initial model for the object to be modeled is displayed to the operator as illuminated from a particular illumination direction and projected onto an image plane.  The operator can update shading of a pixel on the image plane, and, based on the updated shading, the computer graphics system generates an updated normal vector for the updated pixel, which identifies the normal of the surface of the object projected onto the updated pixel. Using the updated normal vector field and a height field, which represents the height of the respective portion of the object as projected onto the respective pixels of the image plane, the computer graphics system generates an updated height value for the updated pixel, thereby to update the height field. The updated normal vector field and the updated height field define the updated model of the object, which corresponds to the updated shape of the object as updated based on the updated shading. The computer graphics system can then display to the operator an image of the object as defined by the updated model. If the updated model is satisfactory, the computer graphics system saves the updated model as the final model. On the other hand, if the updated model is not satisfactory, the operator can further update the shading and enable the computer graphics system to generate a further updated normal vector field and updated height field, thereby to generate a further updated model for the object. The operations can be repeated until the operator determines that the object is satisfactory.
