A procedure is provided wherein a serving general packet radio service (GPRS) support node (SGSN) receives a request for an access point name (APN) the SGSN making a determination if the requested packet data protocol (PDP) and APN are the same as subscribed information. In the event that the requested and subscribed PDP type and the requested and subscribed APN are not the same, the SGSN advises ...

The present invention discloses a method and an apparatus for downlink beam forming in a TD-CDMA system. The method includes: acquiring the spatial covariance matrixes of all uplink slot interference user signals and the downlink slots in which the interference user signals locate; obtaining the interference spatial covariance matrixes of each downlink slot based on the downlink slots in which the...

A method and apparatus for biasing an amplifying device whereby the bias current tracks the input power or the power level of a control signal to thereby efficiently match the bias current with needs of the amplifying device. This method and apparatus overcomes the drawbacks of the prior art by biasing, not for maximum output power, but for the power level of the input signal or the control signal...

A subharmonic mixer and a method of downconverting a received radio frequency signal is described. The subharmonic mixer of the present invention uses two stacks of switching cores with high order symmetry to reduce unwanted harmonic generation and uses transistors to improve headroom.

A method of managing overwrite on an optical disc write once, makes it possible to perform a physical overwrite on the optical disc write once and maintains the continuity of a user data area after performing the physical overwrite. The method includes replacement-recording data, which is requested to be overwritten in a specified area of the disc where recording is completed, from a rear of a use...

The data structure includes a navigation area of the recording medium storing at least one playlist, a first entry point map and a second entry point map. The playlist includes at least one playitem and at least one sub-playitem. The playitem provides navigation information for reproducing at least one still picture from a first file, and the sub-playitem providing navigation information for repro...

The data structure on the recording medium includes a navigation area storing at least one playitem in a playlist. The playitem includes a stream indication field indicating the data streams associated with the playitem. For example, the stream indication field indicates the packet identifiers of the data streams associated with the playitem.

In the method of reproducing still picture data and audio data from a recording medium, the still picture data and the audio data reproduced from the recording medium are decoded based on respective, independent system times (STCs).

The data structure includes a navigation area of the recording medium storing navigation data associated with a data stream representing a portion of the title. The navigation data indicates whether the data stream for the portion of the title represents multiple reproduction paths. The navigation data may further indicate a number of the reproduction paths represented by the data stream when the ...

Systems and methods enable a receiving device and its wireless network to set up resources optimally and efficiently. A sender device signals some of the negotiated QoS parameters to the receiving device of the session during the session set up procedure. The guaranteed bitrate, maximum bitrate, and transfer delay (which are negotiated along with other QoS parameters during PDP context activation)...

An adjustable RF coupling ring is capable of reducing a vertical gap between a substrate and a hot edge ring in a vacuum processing chamber. The reduction of the gap reduces polymer deposits on the substrate and electrostatic chuck and improves wafer processing.

This disclosure provides a system for producing pancreatic islet cells from embryonic stem cells. Differentiation is initiated towards endoderm cells, and focused using reagents that promote emergence of islet precursors and mature insulin-secreting cells. High quality populations of islet cells can be produced in commercial quantities for use in research, drug screening, or regenerative medicine.
