Abstract: A continuously variable transmission (CVT) includes an input member, an output member, a variator assembly having a primary variator pulley operable for receiving an input torque via the input member, a secondary variator pulley operable for transmitting an output torque via the output member, and an endless rotatable drive element in frictional engagement with the primary and secondary variator pulleys, first and second speed sensors operable for measuring a respective rotational speed of the primary and secondary variator pulleys, and a controller. The controller executes a method to detect gross slip of the endless rotatable drive element with respect to the primary and secondary variator pulleys using the measured rotational speeds, and in response to the detected gross slip, to request a reduction in the input torque by a calculated amount over a calibrated duration until a level of the detected gross slip reaches a calibrated slip level.

Abstract: Systems and methods for the washing of biological fluid/biological cells are disclosed. The method provides for the automated dilution of the cell feed during the cell washing procedure using a separator in which the separator has a predetermined maximum output concentration for the biological cells that are being washed. The method further includes determining the concentration ratio of the biological cells to be washed in the washing procedure and determining a maximum input concentration as a function of the maximum output concentration and the concentration ratio. Wash solution is then added to dilute said biological cells so that the maximum input concentration of the diluted biological cells entering the separator is not exceeded.

Abstract: A method of controlling a Micro-Electro-Mechanical System (MEMS) valve includes defining a desired pressure output for the MEMS valve. The desired pressure output is related to a control reference value. The control reference value relates an output pressure of the MEMS valve to a measurable characteristic of the MEMS valve. The measurable characteristic may include a resistance, an electrical power, or an electrical current of the MEMS valve. The control reference value is converted to an initial Pulse Width Modulated (PWM) signal that is applied to the MEMS valve. The initial PWM signal may be adjusted to define an adjusted PWM signal based upon a difference between an actual value of the measurable characteristic at the initial PWM signal and the control reference value, until the actual value of the measurable characteristic at the adjusted PWM signal is within a pre-defined range of the control reference value.
