Appl. No.:

09/342963

Inventors:

Wei Li - Troy MI
Karen Wortham - Livonia MI
John A. George - Chesterfield Township MI

Assignee:

DaimlerChrysler Corporation - Auburn Hills MI

International Classification:

G06F 700

US Classification:

702182, 702183, 702184, 702185, 702188

Abstract:

A method for tracking and monitoring tools in a multi-user environment is provided. The method assigns a unique identification number to each tool which permits the tool to be tracked for purposes of performing operations on the tool, such as periodic performance verification testing and/or preventative maintenance. A user programs the frequency and time at which the operation is to be periodically performed on a tool, such as performance verification testing or preventative maintenance. The method generates routes which enable the operation to be scheduled and performed on selected tools. Data collected from the operation may be uploaded, permitting the method to monitor the performance and/or operation of the tool. In a preferred embodiment, the method compares tool performance to tool operation and calculates tool set-up parameters to tune the performance of the tool to desired levels.

US Classification:

716 10, 716 2, 716 3, 716 9

Abstract:

A method and an apparatus are provided for post-layout optimization of an integrated circuit. In one instance, only local transformations accomplished by incremental changes to placement and routing are provided, so as to avoid the costly design iteration loop that requires re-synthesis, re-place and re-route. Optimization can be provided in multiple optimization phases each accomplishing a specified set of transformations. Static timing analysis is performed at the end of each set of local transformations to determine if further optimization steps are required. In one instance, the physical design is first scanned for mismatch between drivers and loads. Then, in a second optimization phase, âhot spotsâ in the physical design are identified for local transformation using a âbidirectional combinational total negative slackâ (BCTNS) algorithm. In subsequent phases, optimization based on meeting setup times and hold times in a critical path are performed.

Abstract:

An apparatus and a method for removing NOx from an exhaust stream of a lean-burn engine during an engine cold start are provided. The apparatus includes a close-coupled LNT coupled to a main LNT by a hollow conduit. NOx from the cold exhaust is initially stored on the close-coupled LNT. As the engine exhaust warms up, the close-coupled LNT reaches its operating temperature and reduces the stored NOx to N. When the temperature of the close-coupled LNT reaches approximately 350 C. , NOx is released from the close-coupled LNT, is absorbed on the main LNT, and is converted to Nduring fuel-rich conditions, The close-coupled LNT can be regenerated after the engine is turned off by providing heat. The released NOx during the regeneration of the closed-coupled LNT is absorbed by the main LNT. The stored NOx on the main LNT can be reduced to Nduring the next vehicle operation.

US Classification:

348241, 348243

Abstract:

A low cost camera by implementing the major functions in host software is provided. This is accomplished by sending raw, digitized data from the camera directly to the host. The increased volume of raw data is handled by either an improved compression/decompression scheme using lossless compression, using lossy compression or using a shared bus with higher bandwidth. By moving such functions as color processing and scaling to the host, the pixel correction can also be moved to the host. This in turn allows the elimination of the frame buffer memory from the camera. Finally, the camera can use a low cost lens by implementing vignetting, distortion, gamma or aliasing correction with a correction value stored in a register of the camera for later access by the host to perform corrections.

Abstract:

A method and apparatus for performing recursive database operations is provided. According to one aspect, a plurality of first-stage slaves and a plurality of second-stage slaves are established in a database server. During one or more iterations of a recursive database operation, the first-stage slaves concurrently process data items stored in a data repository and send results to the second-stage slaves. The second-stage slaves receive the results and concurrently process those results. The second-stage slaves store the results of the second-stage slaves' processing in the data repository. Subsequent iterations of the recursive database operation proceed in this manner until the recursive database operation has been completed. In each iteration, the first-stage slaves consume the product of the second-stage slaves' previous iteration's processing, and the second-stage slaves consume the product of the first-stage slaves' current iteration's processing.
