Title: Detection and removal of copper from wastewater streams from semiconductor and printed circuit board processing
Inventor: SALMEN KRISTINE S
IPC: G01N21/64
Filed: 1999-08-13
Granted: 2003-01-21
Abstract: A system and method for the detection and removal of copper from wastewater streams from semiconductor or printed circuit board manufacturing is described and claimed. The detection system and method involves the addition of a reagent that reacts with copper to quench the fluorophore present, with the decrease in fluorescence being detected by a fluorometer. The reduction of fluorescence is then used to calculate the amount of copper present in the form of Cu+2 ion in the wastewater. The removal system and method involves either the addition of a polymer that reacts with copper to form an insoluble precipitate with said precipitate then being removed by using any technique commonly known in the art; or the use of an ion exchange column to remove the copper from the wastewater stream.

Filed: 2001-08-02
Granted: 2002-12-01
Abstract: A kind of stage apparatus suitable for use in TIS measurement of an alignment scope is provided in the present invention. A substrate holder (25) is mounted on a stage (WST) moving within a two-dimensional plane, and is capable of holding the substrate (W) and rotating substantially through 180 DEG around a predetermined rotation axis perpendicular to the two-dimensional plane by a drive unit. Therefore, for example, when performing TIS measurement of an alignment scope, laborious operation of mounting the substrate again on the substrate holder after it has been removed from the substrate holder and rotated will not be necessary. Additionally, in this case, since the rotation of the substrate is performed while the substrate is held on the substrate holder, there is no possibility of occurrence of shift for the central position and the like of the substrate before and after the rotation. Therefore, the TIS measurement of the alignment scope can be performed in a short time and with high accuracy.

Title: Method and apparatus for determining a transmission bit rate in a statistical multiplexer
Inventor: LIU VINCENT
IPC: H04N21/434
Filed: 2001-08-13
Granted: 2003-02-01
Abstract: A statistical multiplexer for coding and multiplexing multiple channels of digital television data, or multiple panels of HDTV digital television data. A bit rate need parameter is determined for each encoder in a stat mux group, and an encoding bit rate is allocated to each channel based on its need parameter. A transmission bit rate is allocated to each channel as a time-lagged version of its need parameter to minimize a rate mismatch between the output and the input of a decoder buffer. A packet processor checks for impending decoder buffer overflow or underflow events to set minimum and maximum limits on the transmission bit rate. Moreover, these limits are set based on whether a new transmission bit rate can be implemented before the decoding time stamp (DTS) of the current or next frame.
