Title: Differential displacement optical sensor - ii
Inventor: HAYWARD VINCENT
IPC: G01D5/34
Filed: 2000-03-31
Abstract: Positional sensors receive light that has been reflected off a pair of complementary geometric patterns carried by a supporting carrier surface that is displaceable with respect to the sensors. The sensors view the patterns through viewing windows as the carrier surface and sensors are displaced laterally with respect to each other, presenting differing portions of the patterns to the sensors. The patterns are shaped to produce outputs which, when their difference value is extracted, provide output signals that are a measure of the displacement of the carrier surface with respect to the sensors and in which common mode errors are minimized.

Patent CA-2309379-A1 (CA)
Title: Viral variants and uses therefor
Inventor: TILLMANN HANS
IPC: C12Q1/68
Filed: 2000-06-14
Abstract: The present invention relates generally to viral variants exhibiting reduced sensitivity to particular agents including nucleoside analogues and immunological mediators such as immunoglobulins and immune cells. More particularly, the present invention provides hepatitis B virus (HBV) variants which exhibit a level of replication fitness in the presence of a nucleoside analogue similar to or greater than in the absence of the nucleoside analogue. The detection of such HBV variants is important in the management of therapeutic protocols including the selection of appropriate agents for treating HBV infection. In particular, the present invention contemplates a method of treating HBV infection including a method for identifying a need to change or otherwise alter an existing therapeutic regimen. Furthermore, the method of treatment further encompasses selecting an anti-viral agent or combination of anti-viral agents which would be less likely to result in development of resistance to anti-viral therapy. The method of this aspect of the present invention is predicated in part on monitoring the development in a subject of an increased HBV load in the presence of a nucleoside analogue. This may be manifested by an increase in HBV DNA levels compared to levels in patients prior to treatment. The recognition of such increased viral load and/or DNA levels is indicative of the development of a variant HBV resistant to said nucleoside analogue and an immune mediated response. The clinician is then able to modify an existing treatment protocol or select an appropriate treatment protocol accordingly. The present invention further provides the use of nucleoside analogue-resistant HBV variants which exhibit a similar or increased replication fitness in the presence of the nucleoside analogue compared to in the absence of the nucleoside analogue to screen for medicaments to treat HBV infection.

Filed: 2000-07-21
Abstract: A computer-modeled surface may be an abstract or real surface, and a data representation of the abstract or real surface is used within the computer system as a surface model. In one aspect of the present invention computer-modeled material is distributed over the computer-modeled surface. A coated surface model is produced incorporating the distributed computer-modeled material. The surface model is divided into a plurality of regions. An amount of computer-modeled material to distribute to each region is determined by emitting particles from launch sites associated with the regions. Trajectories reaching a plurality of proximity areas with respect to a plurality of determine an amount of computer-modeled material to allocate to the region.   In another aspect of the invention, computer-modeled material is redistributed after it is distributed onto the regions of the surface model. An elevation of each region with its corresponding amount of computer-modeled material is determined. Elevations which are high with respect to adjacent elevations result in a quantity of the material being moved from one region to another region.        Thus, computer-modeled material is distributed and re-distributed over a computer-modeled surface.
