  • Patent number: 11969213
    Abstract: Provided are apparatuses, a non-transitory computer-readable medium or media, and methods for supporting predicting of vascular disease using a fundus image of a subject. In certain aspects, disclosed a method including the steps of: extracting a feature information from a first fundus image of the subject based on a machine learning model; generating a second fundus image having a feature which is corresponding to the feature information by mapping a saliency factor to the first fundus image; and displaying the first fundus image and the second fundus image on a display device.

  • Patent number: 11332111
    Abstract: A system for and a method of controlling driving of a continuously-operable electronic vacuum pump includes determining conditions for allowing and disallowing first and second electronic vacuum pumps to operate for each braking situation according to vehicle state information associated with braking. The first and second electronic vacuum pumps are driven individually or concurrently according to the determined braking situation. Thus, an optimal negative pressure optimal suitable for the vehicle state information is easily supplied to a booster.

  • Patent number: 10053071
    Abstract: A lane keeping control method for a vehicle may include determining, by a controller, whether a wheel speed difference exists between predetermined wheels, during braking while the vehicle travels straight, determining, by the controller, a reference wheel and a control wheel, based on the wheel speed difference between the predetermined wheels, and reducing, by the controller, a wheel speed difference between the reference wheel and the control wheel by performing pre-decompression control for the control wheel, when the wheel speed difference exists.
