  • Patent number: 11417511
    Abstract: A method for drying a wafer at room temperature includes a cleaning step, a reacting step and a pressure releasing step. The cleaning step includes putting a processing workpiece into a cleaning solvent. The reacting step includes putting the processing workpiece along with the cleaning solvent into a reaction chamber, implanting a supercritical fluid into the reaction chamber, and increasing a pressure of the reaction chamber to dissolve the cleaning solvent in the supercritical fluid. A critical temperature of the supercritical fluid is below room temperature. The pressure releasing step includes releasing the pressure of the reaction chamber and discharging the supercritical fluid together with the cleaning solvent out of the reaction chamber, after completely dissolving the cleaning solvent in the supercritical fluid.

  • 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.

  • Patent number: 8611593
    Abstract: A foreground object detection system and method establishes a background model by reading N frames of a video stream generated by a camera. The detection system further reads each frame of the video stream, detects the pixel value difference and the brightness value difference for each pair of two corresponding pixels of two consecutive frames for each of the N frames of the video stream. In detail, by comparing the pixel value difference with a pixel threshold and by comparing the brightness value difference with a brightness threshold, the detection system may determine a foreground or background pixel.

  • 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.

  • Patent number: 8074062
    Abstract: Methods and systems are disclosed for using a server management program for an error configuration table, wherein a user loads the management program, which receives a Hardware Error Configuration Table (HECT) from baseboard management controller (BMC) firmware, the HECT table containing error control parameters for a hardware error event table. A replica of the HECT is maintained in SRAM using BMC firmware. The HECT is sent via the basic input output system (BIOS) during system power up. An interface is set up to allow the user to configure error event thresholds. The user can set preferred threshold of a system management requirement without rebooting system. If the user makes changes to the HECT, the management program sends the new HECT to BMC firmware to feedback the completion. A software SMI is issued to inform BIOS of HECT changes during the BMC completion. BIOS informs the operating system (OS) to discard and reload the new HECT.

  • Publication number: 20110280442
    Abstract: An object monitoring system and method identify a foreground object from a current frame of a video stream of a monitored area. The object monitoring system determines whether an object has entered or exited the monitored area according to the foreground object, and generates a security alarm. The object monitoring system searches N pieces of reference images just before an image is captured at the time of a generation of the security alarm, and detects information related to the object from the N pieces of reference images. By comparing the related information with vector descriptions of human body models stored in a feature database, and a holder or a remover of the object can be recognized.

  • Publication number: 20110280478
    Abstract: An object monitoring system and method identify a foreground object from a current frame of a video stream of a monitored area. The monitoring system marks foreground pixels of the foreground object as interest points, and identifies a plurality of corresponding pixels of the foreground pixels as the interest points, to obtain a first pixel set. The object monitoring system searches pixels corresponding to the first pixel set from the background model to obtain a second pixel set if a pixel number of the first pixel set is larger than a determined value. By comparing a size of the first pixel set with that of the second pixel set, the object monitoring system can determine whether the object has entered or exited the monitored area.
