A wind energy system 10 comprises a wind tunnel module 12 having openings 14a and 14b at opposite ends. The openings have substantially the same cross-sectional area although the cross-sectional area of the wind tunnel module 12 decreases from the openings 14a and 14b in a direction toward an intermediate portion 16 of the tunnel module. The intermediate portion 16 has a substantially constant cross-sectional area. One or more wind turbines with equal or different number of blades may be mounted in the wind tunnel in or adjacent to the intermediate portion 16. The intermediate portion 16 is bendable to enable the module 12 to conform to a roof 20 of any pitch.

A novel hybrid lithium-ion anode material based on coaxially coated Si shells on vertically aligned carbon nanofiber (CNF) arrays. The unique cup-stacking graphitic microstructure makes the bare vertically aligned CNF array an effective Li+ intercalation medium. Highly reversible Li+ intercalation and extraction were observed at high power rates. More importantly, the highly conductive and mechanically stable CNF core optionally supports a coaxially coated amorphous Si shell which has much higher theoretical specific capacity by forming fully lithiated alloy. The broken graphitic edges at the CNF sidewall ensure good electrical connection with the Si shell during charge/discharge processes.

A method of assembling a magnetoresistive random access memory (MRAM) device includes providing a substrate having an opening. A tape is applied to a surface of the substrate and a first magnetic shield is placed onto the tape and within the substrate opening. An adhesive is applied between the first magnetic shield and the substrate to attach the first magnetic shield to the substrate. An MRAM die is attached to the first magnetic shield and bond pads of the MRAM die are connected to pads on the substrate with wires. A second magnetic shield is attached to a top surface of the MRAM die. An encapsulating material is dispensed onto the substrate, the MRAM die, the second magnetic shield and part of the first magnetic shield, cured, and then the tape is removed. Solder balls then may be attached to the substrate.

A method and a device for preparing a media stream containing more than one component stream for picture-in-picture applications are described along with the corresponding method and device for rendering the media stream in a picture-in-picture mode. The invention allows for live and dynamic picture-in-picture rendering of the component streams contained in the media stream. Extensions to the media formats that shall support various multimedia applications, such as the MPEG-2 Transport Stream and ISO media format, are proposed to enable such a dynamic picture-in-picture functionality.
摘要:
A first handoff is for an inter-AN cell selection where a source AN allows the AT to add a cell under the control of a different AN to its active set and then allows the AT to switch to the target AN. A bearer path is established between the source and target AN to transfer the data traffic using an exchange of messages to register the AT's movement from one BTS to another BTS. The A8/A10 connections remain anchored at the source AN so a bearer path is needed between the source and target AN to transfer the data traffic. The second handoff occurs when the source AN specifies a move of the AT to a new AN proactively. New connections are established at the target AN to support the AT, and the AT is subsequently moved to the target AN via the relevant air-interface messaging.

Systems, methods, and machine-readable and executable instructions are provided for encryption key storage. Encryption key storage may include associating each of a plurality of identifiers with a different one of a plurality of key fragment stores, determining a plurality of indexes, where each of the plurality of indexes is based upon a handle provided by a customer, an authorization token provided by the customer, and a different one of the plurality of identifiers, partitioning an encryption key provided by the customer into a number of encryption key fragments, and distributing the plurality of indexes and the number of encryption key fragments to the plurality of key fragment stores.
摘要:
Substrates, optionally coated with an undercoating, having grafted thereto one or more non-fouling materials are described herein. The non-fouling, polymeric material can be grafted to a variety of functionalized substrate materials, particularly polymeric substrates and/or polymeric undercoatings immobilized on a substrate. The compositions described herein are highly resistant protein absorption, particularly in complex media and retain a high degree of non-fouling activity over long periods of time. The compositions described herein may also demonstrate antimicrobial and/or anti-thrombogenic activity. The non-fouling material can be grafted to a functionalized substrate, or optionally from an undercoating on the substrate, preferably without significantly affecting the mechanical and/or physical properties of the substrate material.

摘要:
The present invention relates to a detection method and a detection kit for EGFR gene mutations, which relates to the therapeutic efficacy of molecular-targeted anti-cancer drugs. Particularly, the present invention relates to a fluorescent quantitative PCR method and kit for detecting mutations at hotspots of EGFR gene, together with the use thereof. The present invention detects the mutations at specific sites of EGFR gene, and can predict the therapeutic efficacy of EGFR tyrosine kinase inhibitors. Therefore, it can provide a guidance to individualize treatments for cancer patients.
