  • Patent number: 11946541
    Abstract: A method of controlling an EOP of a powertrain may include determining, by a controller electrically connected to the EOP, whether an oil sloshing phenomenon in which it is difficult for oil to return to a space where an oil intake port of the EOP is positioned may occur while a vehicle is running; and reducing, by the controller, the revolutions per minute (RPM) of the EOP by a predetermined reduced RPM when it is determined that the oil sloshing phenomenon may occur.

  • Patent number: 9991546
    Abstract: A fuel cell stack assembly device is provided. The assembly device includes a stack guide apparatus that arranges and stacks fuel cells using a plurality of guide bars and a press unit that repeatedly moves vertically based on the stack guide apparatus and presses the fuel cells stacked on the stack guide apparatus. A roller structure includes a roller in rolling contact with the guide bar and is installed at the press unit. A weight detection portion detects weight that is applied to the roller by the guide bar. Additionally, a controller determines whether the guide bar is at the home position based on a detection signal of the weight detection portion and operates the press unit.

  • Patent number: 8364074
    Abstract: Provided is an on-channel repeater capable of removing feedback signals based on pilot partitioning, which can efficiently remove a feedback signal by quickly coping with even a situation in which a feedback channel changes rapidly, by reducing a filter-coefficient update interval, i.e., increasing the number of times of filter-coefficient creation, through pilot partitioning, and a method thereof. The on-channel repeater includes: a receiver for receiving a signal; a subtractor for subtracting a replica of a feedback signal from the signal received in the receiver to remove the feedback signal; a replica creator for creating a filter coefficient using pilot partitioning, creating a replica of the feedback signal using the created filter coefficient, and feeding back the created replica to the subtractor; and a transmitter for transmitting an output signal of the subtractor.

  • Patent number: 5712927
    Abstract: An image processing system for displaying pixel data on a screen performs a binary-encoding method using error diffusion with edge enhancement. In the method for binary-encoding the image data, pixels to be binary-encoded are divided into normal and edge regions, and the pixel data is binary-encoded in accordance with the divided regions. By using the method, bars on the display screen which are unpleasant to the eye can be removed and an image with good edge sharpness can be obtained.
