| 20090304689 | METHODS FOR THE IDENTIFICATION OF POLYPEPTIDE ANTIGENS ASSOCIATED WITH DISORDERS INVOLVING ABERRANT CELL PROLIFERATION AND COMPOSITIONS USEFUL FOR THE TREATMENT OF SUCH DISORDERS - Methods and compositions for the development of effective cancer therapies using mitotic inhibitors which have limited general toxicity to normal, non-cancerous cells and tissues are provided. The methods and compositions utilize cytotoxic compounds comprised of a cell-binding agent (e.g., antibodies) conjugated to an anti-mitotic compound (e.g., maytansinoids). The invention further provides antibodies which are substantially incapable of inducing antibody-dependent cell-mediated cytotoxicity (ADCC) and/or complement dependent cytotoxicity (CDC), thereby ensuring that the therapeutic effect is mediated primarily by the anti-mitotic component of the cytotoxic compound, rather than by indirect cell killing via ADCC and/or CDC. The antibodies of the invention further are capable of differentiating between polypeptide antigens which are more highly expressed on proliferating cancer cells as compared to proliferating non-cancer cells. | 12-10-2009 |

| 20090299573 | SYSTEMS, METHODS AND DEVICES FOR ADAPTIVE STEERING CONTROL OF AUTOMOTIVE VEHICLES - A variety of methods, systems, devices and arrangements are implemented for automated assistance for a driver. One such method relates to a synergistic combination of automation and human control for a motor vehicle traveling on a lane, thereby allowing human-based decisions to be supplement (or be supplemented by) automated decisions. Specific aspects facilitate maintenance of the vehicle on the lane. The vehicle is automatically steered towards a lateral offset within the vehicle lane. Steering input from the driver results in changes to this lateral offset. This modification of the lateral offset can be used to allow the driver to follow any trajectory parallel to the road, including trajectories where the vehicle is not centered within the lane. | 12-03-2009 |
