  • Patent number: 7654436
    Abstract: A wire bonding apparatus and method in which separate first and second positioning tables are provided for mounting electronic devices to be wire bonded, and a bonding tool is provided at a bonding position for bonding the electronic devices. First and second loading/unloading positions are provided for loading electronic devices to or unloading electronic devices from the positioning tables. The first and second positioning tables are operative to move independently of each other, such that the first positioning table is movable between the first loading/unloading position and the bonding position and the second positioning table is movable between the second loading/unloading position and the bonding position.

  • Publication number: 20080046819
    Abstract: A play-oriented workstation is disclosed that has a worktable where an articulatable 2-D or 3-D character is placed among scenery items, an angularly displaceable positioning arm attached to the worktable, a digital camera pivotably attached to the positioning arm and streamlined control key functions that provide creative flexibility and functional transparency. The workstation selectably displays either a real-time video feed from the digital camera in the capture mode on a video screen or else, in the display mode, a stored image that is designated as the current image in response to actuation of a mode key. Pressing a capture/confirm key in the capture mode, captures and stores an image from the video feed as a current image in memory, and re-positioning the articulatable character each time the capture/confirm key is pressed stores images that can subsequently be retrieved as a temporal sequence of stored images as a movie in display mode.

  • Publication number: 20060182118
    Abstract: Disclosed herein is a method for traffic processing to improve the overall performance of data traffic network. The method comprises receiving a traffic having data width narrower than or equal to a predetermined data width; reformatting the received traffic into bus traffic of said predetermined data width; recognizing a specific traffic within the bus traffic; processing the bus traffic; prioritizing the specific traffic, such as voice traffic, over other traffic in said bus traffic; and outputting the bus traffic according to the prioritizing result. Thus, the method secures network resources for voice traffic and avoids frame flooding which may otherwise cause system breakdown. Further disclosed herein is a system for traffic processing.
