Abstract:
In general, techniques are described for emulating mobile authentication methods to establish authenticated connectivity between a mobile service provider gateway and a wireless device attached to an alternate access network. For example, a system operating according to the described techniques includes a mobile service provider network, an alternate access network having an access gateway, and an authentication server of the mobile service provider network that receives a network access request. A subscriber database responds to the network access request with virtual mobility information, wherein the network access request does not include an International Mobile Subscriber Identity (IMSI), and wherein the virtual mobility information comprises a virtual IMSI. The access gateway uses the virtual mobility information to signal a mobile network gateway of the mobile service provider network to establish a service session for the wireless device over the alternate access network that is anchored by the mobile network gateway.
Abstract:
Chemiluminescent acridinium compounds are used in homogeneous assays to determine the concentration of an analyte in a sample without strong acid or strong base treatment. The chemiluminescent acridinium compounds include acridinium esters with electron donating functional groups at the C2 and/or C7 position on the acridinium nucleus to inhibit pseudo-base formation, or acridinium sulfonamides with or without electron donating functional groups at the C2 and/or C7 position on the acridinium nucleus.
Abstract:
A kit for clinical analysis, including a vessel containing magnetizable particles and a magnetic stirring element. A device for distributing magnetizable particles in a fluid including a platform for supporting a vessel containing a fluid, magnetizable particles, and a magnetic stirring element, where the magnetic stirring element moves in a horizontal plane within the vessel. A method for distributing magnetizable particles in a fluid including the steps of providing a vessel containing a magnetic stirring element and a fluid containing magnetizable particles, moving the magnetic stirring element in the vessel, and distributing the magnetizable particles in the fluid.
Abstract:
In general, a mobile virtual private network (VPN) is described in which service provider networks cooperate to dynamically extend a virtual routing area of a home service provider network to the edge of a visited service provider network and thereby enable IP address continuity for a roaming wireless device. In one example, a home service provider network allocates an IP address to a wireless device and establishes a mobile VPN. The home service provider network dynamically provisions a visited service provider network with the mobile VPN, when the wireless device attaches to an access network served by the visited service provider network, to enable the wireless device to exchange network traffic with the visited service provider network using the IP address allocated by the home service provider network.

Abstract:
The present invention provides a method for altering or modifying the content and/or composition of one or more metabolites in the storage organs of a plant, at least comprising the expression of a sulfur-rich protein therein. In particular, the invention provides a method of modifying the fibre content and/or fibre composition and/or starch content and/or nitrogen content and/or non-sulfur-containing amino acid composition and/or anti-nutritional protein content and/or fatty acid content and/or fatty acid composition of the storage organs of a plant. The invention clearly extends to the plants produced by the performance of the inventive method and to genetic constructs which in use produce such plant material.
Abstract:
A high quality TV transmission system is devised including a preprocessing circuit controlled by motion present in the scene to be transmitted. In the absence of motion, processing circuit derives output picture field signals of a standard frequency from a single input picture field scanned at a higher frequency. In the presence of motion, all input picture fields scanned with high number of lines are stored in storing devices and processed by interpolating low pass filters and a multiplexer into output picture fields having the standard frequency but being free of aliansing interference.
Abstract:
A cellular service provider network includes a subscriber database that associate identifiers from the cellular mobile devices (e.g., IMSIs stored within SIM cards of the devices) with layer three (L3) network addresses currently assigned to the cellular mobile device by the cellular network for providing data service to the cellular mobile devices. The subscriber database further stores identifiers for wireless local area network (WLAN) interfaces of the cellular mobile devices. The cellular service provider network includes a server coupled to a layer two (L2) network having a plurality of wireless access points. In response to access requests from the cellular mobile devices over the L2 network, the server queries the subscriber database of the cellular service provider network and assigns the network addresses to the cellular mobile devices by matching L2 network addresses specified within the access requests with the identifiers of WLAN interfaces stored in the subscriber database.
Abstract:
Network devices provide seamless offloading of data communications from a service provider's cellular network to an alternate access network outside of the service provider's cellular network. After a cellular mobile device has initially been authenticated by devices in the cellular network to communicate with a packet data network via the cellular network, the cellular mobile device is configured to leverage its prior authentication on the cellular network and automatically obtain credentials for use in logging onto the alternate access network, without requiring any action by a user of the cellular mobile device. After the cellular mobile device is logged on to the alternate access network, the cellular mobile device sends wireless data communications to the packet data network via the alternate access network instead of the cellular network.
