Patent CA-2431664-A1 (CA)
Inventor: JABAJI ISSAM
IPC: H02P9/30
Filed: 2000-12-15
Abstract: An alternator generates output power at two or more independent voltages (V A ,V B ). The alternator has two independent output windings (110,112) configured to generate the power needed for each output (126,128). Each output voltage (V A ,V B ) is sensed by a regulator (106) that controls switching rectifiers (114,116) to supply the current needed to satisfy the electric power demand of the loads (102,104) connected to each output (126,128). After both output load demands are satisfied, the regulator (106) switches off the alternator field (108). When power demand from either load (102,104) rises, the alternator field (108) is switched on along with the respective switching rectifier (114,116) to satisfy the power demand. The output voltage grounds and control signals may be electrically isolated from each other.

Filed: 2003-08-29
Abstract: A method for making a laminated cross lumber beam comprising the step of stacking elongated wood members and bonding adjacent longitudinal faces thereof along a bonding plane to form intermediary beams. The method further includes a step of selecting intermediary beams having a width greater than a predetermined value and cutting them lengthwise perpendicularly to the bonding planes such as to form panels. The panels and uncut intermediary beams then form sub-beam elements. The method also includes a step of bonding at least two sub-beam elements together side by side to form the laminated cross lumber beam. This method is simplified by the use of small wood members which eliminates the need to cut the intermediary beam to form the sub-beam element. It requires a minimum of steps, thus minimizing costs. The product of this method is a beam with optimized mechanical properties and visual appearance.

Title: Method of finding orphan blocks in block based image compression schemes
Inventor: MYERS JAMES C
IPC: H04N7/26
Filed: 2004-01-14
Abstract: A method of processing the contents of an image which are digitized and formatted into macro blocks (MB) of information. The method involves flagging for further use those macro blocks whose contents satisfy a first criteria. Further processing of the method is performed only using the status of each macro block, either flagged or unflagged, and ignoring the contents. Unflagged blocks adjacent flagged blocks are investigated using a testing protocol and using a second criteria to determine if they should also be flagged. The status of an unflagged block meeting the second criteria is changed from unflagged ("O") to flagged ("1"). The method converts unflagged orphan macro blocks which should have been identified using the first criteria into flagged macro blocks. These are .combined with the original set of flagged macro blocks to determine the entire set of macro blocks whose contents are to be used in subsequent processing.

Title: High aspect stereoscopic mode camera and method
Inventor: BENNETT RUSSELL A
IPC: H04N13/00
Filed: 2002-09-10
Abstract: An aerial reconnaissance camera and method provides for generating a first image of the terrain of interest with the camera pointing angle oriented or rotated about an azimuthal axis some angular amount (.theta.1) to a first, typically forward orientation, i.e., forward of a cross-line of flight direction. An image is obtained of the ground at this orientation. Then the camera is rotated about the azimuthal axis to new angular value (.theta.2), which will typically be aft of the cross line of flight direction. An image is generated at this value. The camera is then rotated back to the value of .theta.1, and a second image in the forward orientation is generated. The camera is then rotated again to the value of .theta.2 and another image in the aft orientation is generated. This process of rotating the camera about the azimuthal axis and generating images in forward and aft orientations continues over and over. Eventually, as the aircraft flies past the terrain of interest, any given location in the terrain of interest will have been imaged from two different perspectives - forward and aft. The motion of the aircraft during the interim in combination with the values of .theta.1 and .theta.2 provide the high baseline for the stereo image pairs.
