    • A method and apparatus for providing radionuclides of bismuth-212 and lead-212. Thorium-228 and carrier solution starting material is input to a radiologically contained portion of an isotopic generator system, and radium-224 is separated from thorium-228 which is retained by a strongly basic anion exchange column. The separated radium-224 is transferred to an accessible, strongly acidic cationic exchange column. The cationic column retains the radium-224, and natural radioactive decay generates bismuth-212 and lead-212. The cationic exchange column can also be separated from the contained portion of the system and utilized without the extraordinary safety measures necessary in the contained portion. Furthermore, the cationic exchange column provides over a relatively long time period the short lived lead-212 and bismuth-212 radionuclides which are useful for a variety of medical therapies.
    • 一种提供铋-212和铅-122的放射性核素的方法和装置。 将Thorium-228和载体溶液起始材料输入到同位素发生器系统的放射学含有部分,并将镭-224与钍-228分离,钍-228被强碱性阴离子交换柱保留。 分离的镭-224转移到可接近的强酸性阳离子交换柱。 阳离子柱保留镭-224,天然放射性衰变产生铋-212和铅-122。 阳离子交换柱也可以与系统的容纳部分分离,并且在所包含的部分中不需要特别的安全措施的情况下使用。 此外,阳离子交换柱在短时间内提供可用于各种医疗疗法的短寿命铅212和铋-212放射性核素。

    • A practical inter-carrier roaming solution by way of a roaming location protocol (RLP) router that provides consistent location support across heterogeneous wireless network standards. The RLP router maintains connectivity to each location server in a roaming ecosystem, alleviating the need for an expensive and impractical mesh network of location servers. When a home location server (H-LS) determines it cannot locate a subscriber device because the subscriber device is roaming, the H-LS sends an RLP request to the RLP router. The RLP router then routes the RLP request to a serving location server (S-LS), which subsequently returns location information for the roaming subscriber device. The RLP router maintains mobile switching center ID (MSCID) to location based services (LBS) mappings for routing RLP requests. The RLP router may also maintain rough MSC-level positioning data for each MSCID to enable the RLP router to resolve certain location fixes without utilizing an S-LS.
    • 通过漫游位置协议(RLP)路由器实现跨运营商漫游解决方案,可在异构无线网络标准之间提供一致的位置支持。 RLP路由器保持与漫游生态系统中的每个位置服务器的连接,减轻了对位置服务器的昂贵且不切实际的网状网络的需求。 当归属位置服务器(H-LS)确定由于用户设备漫游而无法定位用户设备时,H-LS向RLP路由器发送RLP请求。 然后,RLP路由器将RLP请求路由到服务位置服务器(S-LS),随后返回漫游用户设备的位置信息。 RLP路由器将移动交换中心ID(MSCID)维护到用于路由RLP请求的基于位置的服务(LBS)映射。 RLP路由器还可以为每个MSCID维护粗略的MSC级定位数据,以使得RLP路由器能够在不使用S-LS的情况下解决某些定位。
