摘要： A standard cell library is disclosed. The standard cell library contains cells wherein at least one transistor in at least one cell is annotated for gate length biasing. Gate length biasing includes the modification of the gate length, so as to change the speed or power consumption of the modified gate length. The standard cell library is one used in the manufacturing of semiconductor devices (e.g., that result as semiconductor chips), by way of fabricating features defined on one or more layouts of geometric shapes. The annotations serve to identify which ones of the transistor gate features are to be modified before using the geometric shapes for manufacturing the semiconductor device.

摘要： A method for delivering location based information in wireless zone is disclosed. All the location based information is stored in the access point itself thus eliminating the need for backend server. Access point has the intelligence to deliver information in customized to each requesting device's display capability. To provide seamless access to local information the user will get a default web page once the device connects to access point and tries to access internet. This web page will act as a gateway to all the location based information available in the access point. Along with location based information advertisements can also be delivered to the end user in a very cost effective and targeted manner.

摘要： In one embodiment, an apparatus includes a physical port and a plurality of logical sub-interfaces under the physical port. The physical port and the logical sub-interfaces are configured as a Bidirectional Forwarding Detection (BFD) neighbor group. The physical port being configured to run BFD sessions to detect failures at a first rate that is substantially faster as compared to a second rate of BFD sessions to detect failures on the logical sub-interfaces. The physical port notifies the logical sub-interfaces of a BFD failure at the physical port, with the logical sub-interfaces shutting down responsive to the notification.

摘要： A system and method for robust data loss recovery in a wireless local area network is provided. The method includes splitting user data into multiple data fragments. The method further includes creating multiple beacon frames by placing each data fragment in a unique beacon frame and broadcasting the beacon frames through a wireless medium by an access point of the network. Prior to transmission, the method includes arranging the frames into a plurality of groups and creating a parity frame for each group, to be transmitted along with the beacon frame. After transmission, the beacon frames are received by a wireless client and data fragments are extracted from each beacon frame. At the receiving end, the wireless client checks whether all the transmitted beacon frames have been received. Finally, the user data is reconstructed from the extracted data fragments by reassembling the data fragments.

摘要： Methods for generating a biased layout for making an integrated circuit are disclosed. One such method includes obtaining a nominal layout defined by one or more cells, where each cell has one or more transistor gate features with a nominal gate length. Then, obtaining an annotated layout. The annotated layout contains information describing gate-length biasing of one or more of the transistor gate features in one or more cells of the nominal layout. A biased layout is produced by modifying the nominal layout using the information from the annotated layout. The biasing modifies a gate length of those transistor gate features identified by the information of the annotated layout.
