  • SYSTEM FOR RATIONALIZING MEASURED GEAR RATIO VALUES IN A VEHICLE PROPULSION CONTROL SYSTEM
    Publication number: 20180094723
    Abstract: A controller for a vehicle propulsion system that includes a prime mover, a transmission connected to the prime mover to receive input torque on an input shaft and to convert the input torque to an output torque on an output shaft, a transmission input shaft speed sensor, and a transmission output shaft speed sensor. The controller provides a gear ratio value that is based upon a signal indicating an operating condition of the transmission other than a signal from the transmission input shaft speed sensor and the transmission output shaft sensor.

  • Method for sized-based cell separation using spinning membrane filtration
    Patent number: 9713669
    Abstract: A method is provided for separating a suspension of cellular material comprising at least two differently-sized cell types using a spinning membrane separator. The method comprises selecting the cell type to be separated by passing through the membrane; determining a concentration of the selected cell type in the suspension; selecting an inlet flow rate for the suspension; selecting a rotational speed for the spinning membrane separator related to one or more of the concentration and relative size of the selected cell type in the suspension; rotating the spinning membrane separator at the selected rotational speed so that the selected cell type tends to migrate to regions of the shear field adjacent the porous membrane; and flowing the suspension through the spinning membrane separator.
