  • Patent number: 10570371
    Abstract: Provided is a method for isolating and proliferating autologous cancer antigen-specific CD8+ T cells, and more particularly, a method for selecting an epitope recognized by CD8+ T cells from autologous cancer antigens present in blood of individual cancer patients; and isolating autologous cancer antigen-specific CD8+ T cells by using a peptide of the selected epitope, and a method of massively proliferating CD8+ T cells by using the method. According to the present invention, it is possible to isolate autologous cancer antigen-specific CD8+ T cells by using the peptide of the CD8 T cell epitope of the autologous cancer antigen present in blood of individual cancer patients instead of a heterologous antigen. Therefore, by using T cells recognizing the autologous cancer antigen, it is possible to effectively select and eliminate cancer cells derived from the cancer patient's own cells. Thus, T cells can be applied to treatment and alleviation of cancer diseases without side effects.

  • Publication number: 20190280633
    Abstract: A method for reducing code execution time in motor controllers includes receiving a feedback signal from a motor component and transmitting a motor control signal to control the motor component based on first and second attributes of the motor component by iteratively alternating between two modes. In the first mode a first code execution segment is performed utilizing the feedback signal to determine a current value of a first attribute of the motor component, and a current value of a second attribute of the motor component is determined using a past value of the second attribute. In the second mode a second code execution segment is performed utilizing the feedback signal to determine a current value of the second attribute of the motor component, and a current value of the first attribute of the motor component is determined using a past value of the first attribute.

  • Patent number: 10411631
    Abstract: A powertrain system including an electric machine rotatably coupled to a crankshaft of an internal combustion engine via a belt is described, wherein the electric machine is disposed to generate torque. A method for controlling the electric machine includes monitoring rotational position of the electric machine, and periodically executing a speed observer to determine a rotational speed of the electric machine based upon the monitored rotational position of the electric machine. An acceleration observer is periodically executed to determine an acceleration rate, wherein the acceleration rate is determined based upon a time-based change in the rotational speed of the electric machine. A virtual inertia term is determined based upon the acceleration rate, and a torque compensation term is determined based upon the virtual inertia term and the acceleration rate. The electric machine is controlled to generate torque based upon the torque compensation term.
