  • Patent number: 8649313
    Abstract: A mobile station (MS), a base station (BS), a transmission method and a computer storage medium thereof are provided. When the MS requests a bandwidth from the BS, it may generate a selected transmission sequence and a quick access message. The selected transmission sequence comprises pre-defined bit information (e.g., a flow identification, a size of the bandwidth or the like), and the quick access message comprises a station identification of the MS. The MS may transmit the transmission sequence and the quick access message to the BS in a frame so that the BS may allocate the bandwidth to the MS according to the size of the bandwidth, the station identification and the flow identification. Thereby, the amount of the control signals needed when the MS requests a bandwidth from the BS may be decreased.

  • Publication number: 20120257052
    Abstract: In a method for detecting an abnormity of an image capturing device, an image of a monitored area is captured, and an image texture of the image is calculated according to the image. When a count of image textures recorded in a history record list is greater than a predetermined value, the method compares the image texture with at least two image textures recorded in the history record list, to determine whether the image is abnormal. If the image is abnormal, the method increments an abnormity record value of the image capturing device by a value of one. Once the abnormity record value is equal to an alert value, the method generates an alarm to warn of an abnormity of the image capturing device.

  • Publication number: 20110304730
    Abstract: A method for aiming a pan, tilt, and zoom (PTZ) camera captures a first image of a monitored area, and calculates a state vector of a predetermined object or point in the first image at one zoom setting. The state vector of the predetermined object or point is recorded in a state vector table. The method aims the PTZ camera to align a center point of the first image to a selected target point, and captures a second image of the monitored area. In order to calculate state vectors of points in the second image, N pieces of reference images related to the second image are calculated using a particle filter. After calculating a similarity between each of the N pieces of reference images and the second image, the method calculates the state vectors of the points in the second image according to each similarity, and updates the state vector table with the state vectors.
