    Abstract: A method of synchronizing multi-carrier systems is provided, wherein the method comprises inserting a predefined frequency domain signal into a signal on a transmitter side of a multi-carrier system and multi-carrier modulating the signal. Furthermore, the method comprises transmitting the multi-carrier modulated signal via a carrier channel to a receiving side of the multi-carrier system, and synchronizing the multi-carrier modulated signal by using the predefined frequency domain signal portion of the multi-carrier modulated signal.

    Abstract: A method of authentication in an IP Multimedia Subsystem (IMS) is provided. After receiving a Register message from a User Equipment (UE), a Proxy-Call Session Control Function (P-CSCF) locates a Connection Location Function (CLF) according to information contained in the Register message and a pre-configured corresponding relationship between the information contained in the Register message and the CLF. The P-CSCF obtains a query result by querying the CLF about attachment information of the UE in an access network, and sends the Register message carrying the query result to an Interrogating-Call Session Control Function (I-CSCF). The I-CSCF forwards the Register message carrying the query result to a Service-Call Session Control Function (S-CSCF). The S-CSCF authenticates the UE according to an authentication mechanism obtained from a User Profile Service Function (UPSF) or a Home Subscriber Server (HSS), and sends an authentication result to the UE.

    Abstract: Disclosed are methods and apparatus for etching a sample, such as a semiconductor device or wafer. In general terms, embodiments of the present invention allow dry etching of a material on a sample, such as a copper material, at room temperature using a reactive substance, such as a chorine based gas. For example, the mechanisms of the present invention allow precise etching of a copper material to produce fine feature patterns without heating up the whole device or substrate to an elevated temperature such as 50° C. and above. The etching is assisted by simultaneously scanning a charged particle beam, such as an electron beam, and a photon beam, such as a laser beam, over a same target area of the sample while the reactive substance is introduced near the same target area. The reactive substance, charged particle beam, and photon beam act in combination to etch the sample at the target area. For example, a copper layer may be etched using the mechanisms of the present invention.

    Abstract: A first wireless communications device includes a wide area network (WAN) interface and a peer to peer interface. The first device discovers the presence of a second wireless communications device via a peer discovery signal, received via its peer to peer interface. The second device has been transmitting, e.g., periodically, certain information, e.g., its location and/or shopping preferences, to a node within the WAN. The detected first signal triggers an application alert in the first device. The first device recovers past information about the second device through a second signal received via its WAN interface. The first device uses information communicated in the first signal, e.g., device identifier information, and information communicated in the second signal, e.g., past location and/or shopping information, to generate a targeted message for the second device. The first device communicates the targeted message via its peer to peer interface in a peer to peer traffic channel.
