  • Publication number: 20170270981
    Abstract: A semiconductor memory apparatus may include a memory cell circuit, a data latch circuit, and a first stage amplification circuit. The data latch circuit may be electrically coupled to the memory cell circuit by a bit line. The data latch circuit may latch data transferred through the bit line. The data latch circuit may output latched data to an input/output line in response to a cell select signal. The data first stage amplification circuit may generate driving data to a voltage level of an external power supply voltage in response to a voltage level of the input/output line. The data first stage amplification circuit may precharge the input/output line to a voltage level lower than the external power supply voltage and higher than a ground voltage in response to a precharge signal.

  • Patent number: 9230176
    Abstract: A method of detecting camera tempering and a system therefor are provided. The method includes: performing at least one of following operations: (i) detecting a size of a foreground in an image, and determining whether a first condition, that the size exceeds a first reference value, is satisfied, (ii) detecting change of a sum of the largest pixel value differences among pixel value differences between adjacent pixels in selected horizontal lines of the image, according to time, and determining whether a second condition, that the change lasts for a predetermined time period, is satisfied, and (iii) adding up a plurality of global motion vectors with respect to a plurality of images, and determining whether a third condition, that a sum of the global motion vectors exceeds a second reference value, is satisfied; and determining occurrence of camera tempering if at least one of the corresponding conditions is satisfied.

  • Patent number: 8317716
    Abstract: Disclosed herein is a system for diagnosing a deficient pulse and an forceful pulse. The system includes a pulse diagnotic device, a deficient pulse and forceful pulse determining device, and an output device. The pulse diagnotic device measures pulse condition information at an examinee's Cun (˜\f˜) Gu (H), and Chi (,R) pulse-taking locations on his or her wrist using one or more pulse-taking sensors. The deficient pulse and forceful pulse determining device is operably connected to the pulse diagnotic device, analyzes the pulse pressure information measured by the pulse diagnotic device, calculates a quantified deficiency/forceful coefficient, and determines whether a pulse of interest is a deficient pulse or an forceful pulse. The output device is connected to the determining device and displays results of the determination.

  • Publication number: 20110134236
    Abstract: A method and apparatus for stabilizing a locus of an object detected from a continuously-captured image, and an image monitoring system are provided. The apparatus includes: a detection unit which detects first information about the locus provided at a first time, from the continuously-captured image; a storage unit which stores second information about the locus provided at at least one other time; a correction unit which corrects the first information based on the second information; and a display unit which applies the corrected first information to the object in the continuously-captured image to display a modified locus corresponding to the corrected first information.
