20090279350 | BIPOLAR SWITCHING OF PHASE CHANGE DEVICE - Memory devices and methods for operating such devices are described herein. A method as described herein includes applying a reset bias arrangement to a memory cell to change the resistance state from the lower resistance state to the higher resistance state. The reset bias arrangement comprises a first voltage pulse. The method further includes applying a set bias arrangement to the memory cell to change the resistance state from the higher resistance state to the lower resistance state. The set bias arrangement comprises a second voltage pulse, the second voltage pulse having a voltage polarity different from that of the first voltage pulse. | 11-12-2009 |
20090323409 | METHODS FOR HIGH SPEED READING OPERATION OF PHASE CHANGE MEMORY AND DEVICE EMPLOYING SAME - Phase change based memory devices and methods for operating described herein overcome the performance limitations of slow set speeds and long recovery times commonly associated with phase change memory devices, enabling high speed operation and extending their usefulness into high speed applications typically filled by DRAM and SRAM memory. | 12-31-2009 |
20110180775 | PROGRAMMABLE METALLIZATION CELL WITH ION BUFFER LAYER - A programmable metallization device, comprises a first electrode; a memory layer electrically coupled to the first electrode and adapted for electrolytic formation and destruction of a conducting bridge therethrough; an ion-supplying layer containing a source of ions of a first metal element capable of diffusion into and out of the memory layer; a conductive ion buffer layer between the ion-supplying layer and the memory layer, and which allows diffusion therethrough of said ions; and a second electrode electrically coupled to the ion-supplying layer. Circuitry is coupled to the device to apply bias voltages to the first and second electrodes to induce creation and destruction of conducting bridges including the first metal element in the memory layer. The ion buffer layer can improve retention of the conducting bridge by reducing the likelihood that the first metallic element will be absorbed into the ion supplying layer. | 07-28-2011 |

20120063746 | METHOD AND APPARATUS FOR EXTRACTING KEY FRAMES FROM A VIDEO - The present invention relates to a method and apparatus for extracting key frames from a video. The method includes: dividing the video into multiple levels of video segments, wherein each video segment at a non-lowest level comprises one or more video segments at the next lower level, the multiple levels range from a first level to an N-th level, N is an integer greater than 1, the first level is the lowest level, and the N-th level is the highest level; extracting from video segments of the video at a non-highest level candidate frames at the non-highest level; for each level from a next higher level to the highest level, selecting zero, one or more candidate frames at the level from candidate frames at the next lower level in each video segment at the level; and outputting the candidate frames at the highest level as the key frames of the video. | 03-15-2012 |
20120293663 | DEVICE FOR DETERMINING DISAPPEARING DIRECTION AND METHOD THEREOF, APPARATUS FOR VIDEO CAMERA CALIBRATION AND METHOD THEREOF - A disappearing direction determination device and method, a video camera calibration apparatus and method, a video camera and a computer program product are provided. The device comprises: a moving target detecting unit for detecting in the video image a moving target area where a moving object locates; a feature point extracting unit for extracting at least one feature point on the moving object in the detected moving target area; a moving trajectory obtaining unit for tracking a movement of the feature point in a predetermined number of video image frames to obtain a movement trajectory of the feature point; and a disappearing direction determining unit for determining, according to the movement trajectories of one or more moving objects in the video image, a disappearing direction pointed by a major moving direction of the moving objects. Thus, a disappearing direction and video camera gesture parameters can be determined accurately. | 11-22-2012 |
