  • COMPUTING DEVICE, STORAGE MEDIUM AND METHOD FOR IDENTIFYING DIFFERENCES BETWEEN TWO IMAGES
    Publication number: 20120320223
    Abstract: In a method for identifying differences between two images using a computing device, a digital image of the object is captured using an image capturing device, and a standard image of the object is obtained from a storage system of the computing device. A threshold value is generated according to pixel values of the digital image and the standard image. The method extracts first feature points from the digital image and second feature points from the second gray picture according to the threshold value. The method further determines a first feature area of the first gray picture according to the first feature points, determines a second feature area of the second gray picture according to the second feature points, and compares the first feature area with the second feature area to identify a difference between the digital image and the standard image.

  • SHEET ALIGNMENT DEVICE
    Publication number: 20120299239
    Abstract: A sheet alignment device includes a first alignment arm, a second alignment arm, a first sensor and a controller. The first alignment arm includes a first blocking piece and a second blocking piece. During the sheet-aligning action of each sheet, the first alignment arm is moved for a preset distance from a standby position. Then, the first alignment arm is moved back to the standby position, and a waiting time is required to introduce a next sheet into the sheet placement tray. When the first sensor is no longer interrupted by the second blocking piece of the first alignment arm, the controller starts to calculate the moving distance of the first alignment arm. Since the moving distance of the first alignment arm is calculated at the same start point during the sheet-aligning action of each sheet is performed, the possibility of resulting in the moving distance error is minimized.

  • Soft collector for a negative pressure wound therapy system and its combination
    Patent number: 8303555
    Abstract: A collector for a negative pressure wound therapy system has a soft collecting bag with a gas-permeable unit and a liquid absorber. The collecting bag is connected to a wound-dressing unit via an inlet connecting set and is connected to a sensor assembly via a detecting connecting set. With the soft collecting bag, the collector occupies less volume. By the gas-permeable unit and the liquid absorber, the liquid and gas entering into the collecting bag quickly isolate. Moreover, multiple collectors connect in series to form a collector combination to reduce the frequency to replace the collector combination so that a longer usage time of the collector combination is available.

  • Multistep method of depositing metal seed layers
    Patent number: 8298936
    Abstract: Metal seed layers are deposited on a semiconductor substrate having recessed features by a method that involves at least three operations. In this method, a first layer of metal is deposited onto the substrate to cover at least the bottom portions of the recessed features. The first layer of metal is subsequently redistributed to improve sidewall coverage of the recessed features. Next, a second layer of metal is deposited on at least the field region of the substrate and on the bottom portions of the recessed features. The method can be implemented using a PVD apparatus that allows deposition and resputtering operations. This sequence of operations can afford seed layers with improved step coverage. It also leads to decreased formation of voids in interconnects, and to improved resistance characteristics of formed IC devices.

  • Method and device for encoding and decoding color enhancement layer for video
    Patent number: 8295625
    Abstract: Enhanced dynamic range requires more than 8 bit representation for single color components of pixels. For this purpose, normal color resolution images and high color resolution images are available. Backward compatibility can be achieved by a layered approach using a color enhancement layer, and a conventional image as color base layer. Both have same spatial and temporal resolution. Encoding of the color enhancement layer uses prediction and residual. A methods for optimized color enhancement prediction is disclosed. Color bit depth prediction is done by constructing a polynomial that approximates for all pixels of one color component of a block the color enhancement layer from the color base layer. A predicted version of the high color resolution image and a residual are generated and updated by a residual. The coefficients are compressed and added as metadata to the data stream.
