  • Patent number: 11217343
    Abstract: An electronic device includes a sensor, a processor, and a memory configured to store at least one instruction executed by the processor, wherein the processor is configured to collect activity information on a user related to the electronic device by using the sensor, the collecting of the activity information including creating an amount of activity of the user for a specific goal or an activity engagement level for the specific goal by using the activity information, adjust at least one of an output time point, an output cycle, the number of outputs, or the output contents of the activity guide information for the user to an activity guide parameter at least based on the amount of activity or the activity engagement level, and output the activity guide information created by using the adjusted activity guide parameter through an output device operatively connected to the processor.

  • Patent number: 10431320
    Abstract: A method of testing a semiconductor memory device is provided. Data is written to a plurality of memory cells disposed in a memory cell block of the semiconductor memory device. A first driving voltage is applied to a first group of word lines. A second driving voltage is applied to a second group of word lines. Each word line of the first group of the word lines is interposed between two neighboring word lines of the second group of the word lines. The first driving voltage has a voltage level different from that of the second driving voltage. The data is read from first memory cells coupled to the first group to determine whether each of the first memory cells is defective.

  • Publication number: 20100245562
    Abstract: Disclosed a method and device for detecting a shape of a sheet roll. The method for detecting a shape of a sheet roll comprises positioning a camera on a cylindrical side surface of the sheet roll; photographing a cylindrical side surface while rotating the camera along the cylindrical side surface of a sheet roll; and determining whether there is a defect in a shape of a winding roll by analyzing a pattern of an image acquired by photographing.
