Patent CA-2236123-A1 (CA)
Title: Conversion of pyridinoline to deoxypyridinoline
Inventor: JOHNSON GARY M
IPC: G01N33/00
Filed: 1998-04-29
Abstract: The present invention involves the synthetic conversion of pyridinoline (PYD) to deoxypyridinoline (DPD) via an intermediate ester which is subsequently cleaved.  The transformation of PYD into a xanthate-type ester intermediate facilitates the subsequent removal of the substituted hydroxyl functionality thus providing the desired DPD.  The method provides a new chemical pathway for the preparation of DPD, resulting in significantly increased yields as compared to traditional methods of product isolation.

Title: Upright type vacuum cleaner capable of switching between suction path corresponding to place to be cleaned
Inventor: NISHINAKA NOBORU
IPC: A47L9/24
Filed: 1998-05-19
Abstract: A dust collecting direction switching portion is provided at a wall at the back of the main body of an upright type vacuum cleaner.  The dust collecting switching portion having a switch valve is branched into three directions.  The branch in the first direction forms a rib for allowing a coupling hose to be fitted to a suction opening directed toward a floor surface, the branch in the second direction forms a rib communicating with a dust collecting portion inside the vacuum cleaner, and the branch in the third direction forms a rib allowing a hose to collect dust at a relatively narrow space between pieces of furniture.  In operation, in response to an operation of a knob related to the switch valve, the switch valve switches one of the first and third direction ribs in association with the operation to communicate with the rib in the second direction.

IPC: G01N33/50
Filed: 1997-05-01
Abstract: A method for detecting malignancy-associated changes. A sample of cells is obtained and stained to identify the nuclear DNA  material. The sample is imaged with a digital microscope. Objects of interest are identified in the sample of cells based on the intensity of the pixels that comprise the object versus the average intensity of all pixels in the slide image. An exact edge is located for each object and variations in the illumination intensity of the microscope are compensated for. A computer system calculates feature values for each object and, based on the value of the features, a determination is made whether the cell exhibits malignancy-associated changes or not.

Title: Use of a multi-component coil medical construct
Inventor: COOPER KEVIN L
IPC: A61F2/06
Filed: 1998-12-16
Abstract: There is described a process for deploying a medical construct in a body cavity, so as to function for example as a stent in a body lumen. The construct is used by forming a coil from a strand that has an interior and an exterior portion, and thereafter heating while expanding the coil so as to melt only the exterior portion. When that melted portion resolidifies with the coil in the expanded state, the coil's integrity and resistance against forces such as compression is maintained by the unmelted but stretched interior portion, and the expanded shape is maintained by the adhesiveness of the solidified exterior portion.

Filed: 1998-01-21
Abstract: A relatively narrow beam of either RF or optical electromagnetic radiation is scanned over a relatively wide azimuthal range. The return signal is processed to detect the range and velocity of each point of reflection. Individual targets are identified by clustering analysis (102) and are tracked (106) in a Cartesian coordinate system using a Kalman filter. The threat to the vehicle for a given target is assessed (116) from estimates of the relative distance, velocity, and size of each target, and one or more vehicular devices are controlled (120) responsive to the assessment of threat so as to enhance the safety of the vehicle occupant. In a preferred embodiment, a quantized linear frequency modulated continuous wave RF signal is transmitted from and received by a multi-beam antenna having an azimuthal range of at least +/- 100 degrees and an individual beam width of approximately 10 degrees.
