Abstract:

A method of receiving data packets. In the method of receiving data packets, a determination is made as to whether a received data packet is received out of an expected order. If the determining step determines a received packet is out of the expected order, a time period is calculated to wait for one or more missing data packets based at least in part on an expected time of receiving the one or more missing data packets.

Abstract:

A method and an apparatus for reducing packet loss for a packet data service during congestion in a transport network are provided. The method comprises measuring a packet loss rate over a time period in one or more flows of data traffic packets associated with the packet data service to determine whether the one or more flows of data traffic packets are experiencing a variation in a desired traffic performance level at a particular time duration during the congestion in the time period. The method further comprises triggering a request to reduce a flow rate of at least one of the one or more flows of data traffic packets based on the packet loss rate if the at least one of the one or more flows of data traffic packets experiences the variation in the desired traffic performance level. By using a distributed transport congestion control, for example, only such Best Effort data traffic packet flows that generate bursty traffic at a specific moment of congestion sense the congestion and thus trigger an associated rate reduction action. However, other flows that do not experience the congestion may not be affected.

US Classification:

705 54, 713155, 709203

Abstract:

A system and method for enforcing rights expressions, include specifying a repository rights expression indicating a manner of use of an item at a repository; and associating the repository rights expression with the repository. In a further embodiment, the system includes one or more repositories having associated therewith rights expressions further indicating a condition of use of the item at the repository. In a further embodiment, a repository for use in the system, includes a processor module configured to process the rights expression associated with the repository; and a determination module configured to determine based on the rights expression associated with the repository what action the repository is to take when the repository processes or receives a request for the item. The manner of use or condition of use indicates what action the repository is to take when the repository processes or receives a request for the item.

Appl. No.:

Inventors:

Zhiqiang Wu - Allen TX, US
Xin Wang - New York NY, US

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

H01L 21/336

US Classification:

438293, 438308

Abstract:

The invention provides a method of fabricating a semiconductor device that enhances the amount of stress that is transmitted to the channel region for carrier mobility enhancement. In one embodiment an amorphous region is formed at or near the gate dielectric interface prior to source/drain anneal. In a second embodiment the gate material is amorphous as deposited and processing temperatures are kept below the gate material crystallization temperature until stress enhancement processing has been completed. The amorphous gate material deforms during high temperature anneal and converts from an amorphous to a polycrystalline phase allowing more stress to be transmitted into the channel region. This enhances carrier mobility and improves transistor drive current.

International Classification:

H01L 21/8238

US Classification:

438199, 257369

Abstract:

A gate stack for an NMOS transistor in an IC to induce tensile stress in the NMOS channel is disclosed. The gate stack includes a first layer of undoped polysilicon, a second layer of n-type polysilicon to establish a desired work function in the gate, layer of compressively stressed metal, and a third layer of polysilicon to provide a silicon surface for subsequent formation of metal silicide. Candidates for the compressively stressed metal are TiN, TaN, W, and Mo. In a CMOS IC, the n-type polysilicon layer and metal layer are patterned in NMOS transistor areas, while the first polysilicon layer and third polysilicon layer are patterned in both NMOS and PMOS transistor areas. Polysilicon CMP may be used to reduce topography between the NMOS and PMOS gate stacks to facilitate gate pattern photolithography.

International Classification:

G01R 31/08

US Classification:

370236

Abstract:

The invention includes a method and apparatus adapted for controlling congestion in a Radio Access Network (RAN). In one embodiment, a method includes monitoring packets received at a first network element of the RAN for an indication of congestion, where the packets are associated with a quality-of-service class, and, in response to detecting an indication of congestion in at least one of the received packets, signaling congestion status information from the first network element of the RAN toward a second network element of the RAN that is adapted for applying congestion control for the quality-of-service class. In one embodiment, a method includes receiving, at a first network element of the RAN, from a second network element of the RAN, congestion status signaling indicative of a congestion condition associated with a quality-of-service class, and applying congestion control for the quality-of-service class in response to receiving the congestion status signaling indicative of the congestion condition.

The assembly includes a test sensor having a fluid-receiving area for receiving a sample of body fluid, where the fluid-receiving area contains a reagent that produces a measurable reaction with an analyte in the sample. The assembly also includes a meter having a port or opening configured to receive the test sensor; a measurement system configured to determine a measurement of the reaction between the reagent and the analyte; and a temperature-measuring system configured to determine a measurement of the test-sensor temperature when the test sensor is received into the opening. The meter determines a concentration of the analyte in the sample according to the measurement of the reaction and the measurement of the test-sensor temperature.
