  • Patent number: 10341981
    Abstract: Disclosed is a system for recognizing a user location using sensor-based activity recognition. The system includes a mobile device which includes a sensor module configured to sense information about at least one of a user state and surrounding environments, a first processor configured to extract activity information based on the sensed information, and a first communication module configured to transmit the extracted activity information; and a user terminal device which includes a second communication module configured to receive the activity information from the first communication module, and a processor configured to determine a user location in a user space corresponding to a user activity based on the received activity information. By determining a user's location in a user space corresponding to a user activity, it is possible to control electronic devices corresponding to the user activity or provide a service of monitoring activities of the old and weak and the child.

  • Patent number: 7871788
    Abstract: Means for easily determining the grade of malignancy of cancer cells. The amount of ATBF1 in the whole cell structure of test cancer cells separated from a living organism is detected, and on the basis of detection results, the grade of malignancy of test cancer cells is judged. Alternatively, the amount of ATBF1 in the nuclei of test cancer cells separated from a living organism is detected, and on the basis of detection results, the grade of malignancy of test cancer cells is judged. Still alternatively, the amount of ATBF1 in the cytoplasms of test cancer cells separated from a living organism is detected, and on the basis of detection results, the grade of malignancy of test cancer cells is judged.
