  • Patent number: 10261590
    Abstract: An apparatus and method to recognize a moving direction of gesture are provided. A final moving direction of gesture is determined using the number of intersecting points based on output values from one or more sensors disposed in up, down, left, right directions and a code of an accumulated sum. Thus, a moving direction of target (hand) that moves on the sensors is recognized more accurately. The apparatus to recognize a moving direction of a gesture includes first to fourth sensor disposed at a position that is north, south, west, and east from a center; and a controller configured to identify a number of intersecting points based on output values of the first sensor, the second sensor, the third sensor and the fourth sensor and to estimate a moving direction of the gesture according to the number of the intersecting points.

  • Patent number: 9281836
    Abstract: Provided is an integrating analog-digital converter. According to the present examples, the resistance against external noise is improved by incorporating a differential amplifier into an integrating analog-digital converter. Some examples also include a section where an input voltage and a reference voltage are simultaneously blocked such that switching noise may be minimized and a reference voltage may also be stably supplied. Further, examples are designed to manage a residue, which may be generated when an integral operation to an analog input value is finished, to be processed not in an additional converter but in control logic itself, thereby reducing a size of a circuit device.
