A data center cooling solution providing techniques for using baffles, doors and roof sections to prevent warm air from being entrained into a cold aisle in a data center, wherein the data center generally contains an air cooling system and a raised floor structure. The raised floor structure is configured to deliver cool air into the data center through a plurality of grates and perforated tiles in the floor. Electronic equipment racks are disposed around the grates and perforated tiles, such that the front faces of the equipment racks face the grates and perforated tiles. A collection of baffles, doors or roof sections inhibit the mixing of the cool air delivered by the air cooling system and the warm air exhausted by the electronic equipment.

By providing a substantially non-damaged semiconductor region between a pre-amorphization region and the gate electrode structure, an increase of series resistance at the drain side during the re-crystallization may be reduced, thereby contributing to overall transistor performance, in particular in the linear operating mode. Thus, symmetric and asymmetric transistor architectures may be achieved with enhanced performance without unduly adding to overall process complexity.

A system, method, and computer program product for creating a sequence of computer graphics frames, using a plurality of rendering pipelines. For each frame, each rendering pipeline receives a subset of the total amount of graphics data for the particular frame. At the completion of a frame, each rendering pipeline sends a performance report to a performance monitor. The performance monitor determines whether or not there was a significant disparity in the time required by the respective rendering pipelines to render their tiles. If a disparity is detected, and if the disparity is determined to be greater than some threshold, an allocation module resizes the tiles for the next frame. This serves to balance the load across rendering pipelines for each frame.

An apparatus for testing semiconductor devices allows various testing processes, including a burn-in process, to be performed at the same testing stage. Test trays which contain the semiconductor devices are used throughout an in-line system so that an entire back-end process can be performed without loading / unloading the semiconductor devices between the various tests. The in-line system includes multiple test and burn-in apparatuses as well as a single sorting unit which performs a composite sorting operation after all the testing processes. A method for testing semiconductor devices in the in-line system includes testing the semiconductor devices in the test trays using the test and burn-in apparatus, transferring the test trays to a different testing apparatus for a second testing, and finally sorting the semiconductor devices after all testing processes have been performed based on a final sorting map created by combining test tray maps generated during each of the tests.

A test and burn-in apparatus for semiconductor chip package devices, an in-line system which includes the test and burn-in apparatus, and a test method which employs the in-line system are provided. A test and burn-in apparatus for testing semiconductor devices allows various testing processes, including a burn-in process, to be performed at the same testing stage. The apparatus employs test trays which contain the semiconductor devices. These test trays are used throughout the in-line system so that an entire back-end process can be performed without the need for loading / unloading the semiconductor devices into and from device trays between the various tests. The test and burn-in apparatus according to this invention can therefore occupy less space than the prior art testing apparatuses. The in-line system includes multiple test and burn-in apparatuses as well as a single sorting unit which performs a composite sorting operation after all the testing processes have been performed. Furthermore, the method for testing the semiconductor devices in the in-line system includes testing the semiconductor devices in the test trays using the test and burn-in apparatus, generating a test tray map corresponding to results of the test, transferring the test trays to a different testing apparatus for a second testing and test tray map generation process, and finally sorting the semiconductor devices in the sorting unit after all testing processes have been performed based on a final sorting map created by combining the test tray maps of each of the tests. The benefits of this invention are reduced time and space requirements because neither transferring the devices to device trays between tests nor performing multiple sorting steps are required.

A data communication system that provides different types of service (e.g., telephone services and high-speed data transmission services) to a remote site even when the remote site lacks a splitter is disclosed. A central site (e.g., central office) is able to communicate with at least two different types of remote sites. One type of remote site includes a full splitter (i.e., both low-pass and high-pass filters), and the other type of remote site has only a partial splitter (i.e., includes high-pass filter but lacks a low-pass filter). Although conventionally the transceivers (e.g., ADSL transceivers) at these remote sites would be of the same design and use the same modulation technique for upstream as for downstream transmissions, here the remote site that lacks a low-pass filter (i.e., partial splitter type remote site) uses a different modulation technique for upstream transmissions. As an example, in a data communication system where a remote site lacks a complete splitter, a high peak-average-ratio (PAR) technique like discrete multi-tone (DMT) can be used with downstream transmissions that do not lead to noise at the telephone service even in the splitterless design, and a lower PAR technique (e.g., CPM, QAM, FSK, etc.) can be used with upstream transmissions so that the noise levels produced at the telephone service are vastly reduced. The central site is able to communicate with both the different types of remote sites. The central site selects from various receiver units depending on the type of modulation (e.g., low PAR technique) used.
