  • Patent number: 11364949
    Abstract: A steering-angle-limiting device of a steer-by-wire system selectively restricts turning of a steering wheel in a forward direction or in a reverse direction and permits turning of the steering wheel in order to inhibit locking of the steering wheel when the steering-angle-limiting device operates abnormally. Rotation of a stopping gear, which is coupled to a steering shaft, is selectively restricted depending on a change in a rotation angle of a cam, whereby the direction in which the steering wheel turns is selectively limited. In addition, when a stopper operates abnormally, the stopper is moved to a position apart from an end of the radius of rotation of the stopping gear, thereby enabling turning of the steering wheel.

  • Patent number: 11363252
    Abstract: A method of operating an image sensing device includes applying control voltages to a pixel array in accordance with a test mode and performing an analog-to-digital conversion of a column line voltage to obtain one or more digital codes. The one or more digital codes are evaluated to detect an operating error associated with the column line and/or corresponding analog to digital converter. In response to an operating error, pixel values may be replaced or averaged with nearby pixel outputs not affected by the operating error.
