摘要： A GPS information service system for providing supplemental GPS correction and signal acquisition information to subscribers. A GPS information server broadcasts GPS aiding information encrypted with subscription keys. A remote GPS subscription unit receives the key enablers for the subscription keys in service activation (SAM) messages for the services for which they have subscribed and then uses the subscription keys to decrypt the GPS aiding information. In order to prevent unauthorized access to the information, unsymmetrical signature generation and authentication algorithms are used for generating and authenticating signatures for the SAM messages.

摘要： A hollow pedestal bed end for a rise and fall patient's bed is made of reduced width to fold over the mattress frame and pass through a door opening. The inner faces of the paired bed ends each have a slot through which a mattress frame bracket projects. A wheeled carriage inside the bed end rides on an upright guide and the bracket projects from the guide. The rise and fall motion is supplied by a linear actuator whose small movements are multiplied by a third order lever. The frame is thus lifted by a pair of such pedestal ends.

摘要： A method and system for communication in a real-time kinematic (RTK) positioning system by paging. An RTK positioning system having a reference station and a rover utilizes a paging system for data transfer. A single satellite positioning system (SATPS) reference station may be coupled to the paging system to provide RTK correction data, or multiple networked reference stations may be coupled to the paging system to provide data. Paging systems using allocated paging bands having fixed width channels (e.g. 20 kHz) such as those between 35 MHz and 36 MHz or 43 MHz and 44 MHz may be used.

摘要： A process for sorting large files or structures is disclosed where improved performance is achieved by reducing the work involved and the time required to do record key comparisons. The reduction is achieved by transposing and saving the key data from each record into a representative form that can be more quickly compared each time the key comparison is required. In addition the process uses pointers to avoid the processing time to exchange records larger than one word in memory. The representation of the key data is optimized and aligned for comparison by word based computer instructions which are typically faster than byte based instructions. The process is optimized for word sizes and instructions which handle words larger than four bytes and in particular for machines and instructions with 64-bit or larger word sizes such as the Intel Itanium series processors.
摘要翻译：公开了用于排序大文件或结构的过程，其中通过减少所涉及的工作和进行记录密钥比较所需的时间来实现改进的性能。通过将每个记录中的关键数据转换并保存为代表性的形式来实现减少，每当需要进行关键比较时，可以更快速地比较关键数据。此外，该过程使用指针来避免处理时间来交换内存中大于一个字的记录。密钥数据的表示被优化并对齐，用于通过基于字节的计算机指令进行比较，其通常比基于字节的指令快。该过程针对处理大于四个字节的字的字大小和指令进行了优化，特别是针对具有64位或更大字体大小的机器和指令（如Intel Itanium系列处理器）进行了优化。

摘要： A positioning system or synthetic phase processor or rover station for providing high integrity positions with graduated accuracies. The positioning system includes one or more real time kinematic (RTK) reference stations for receiving GPS signals at established reference positions and measuring reference phases. The positioning system or the rover station selects a synthetic offset vector and uses the synthetic offset vector for inferring synthetic reference phases to a synthetic position. The rover station uses the synthetic reference phases with actual or virtual reference positions for determining a rover position having an added positional error controlled by the synthetic offset vector. For another embodiment a secure rover station dithers a secure position with a synthetic offset vector for providing an unsecure rover position having the added positional error.

摘要： The present invention relates to photonic crystal fibers, in particular to photonic crystal fibers that guide light by virtue of a photonic band gap. It is an object of the present invention to provide such fibers that are formed from materials having higher refractive indices than silica. The object is achieved by an elongate waveguide comprising a core with a relatively low refractive index and a photonic band gap structure that can substantially confine light to the core, the structure comprising elongate regions of relatively low refractive index interspersed with elongate regions of relatively high refractive index wherein the band gap resides above the fifth photonic band of the band gap structure. Alternatively the photonic band gap may have a V0-value in the range 130≦V02≦160. Alternatively the waveguide has a lattice pitch Λ and the elongate regions have a transverse dimension d, wherein the photonic band gap has a normalized centre frequency k0Λ in the range 5≦k0Λ≦6, when d/Λ=0.8 and the refractive index contrast is 2.4, or a normalized centre frequency k0Λ of the same photonic band gap that is scaled with either or both of d/Λ and the refractive index contrast between the relatively high index and the relatively low refractive index. The invention further relates to a method of operating the waveguides and to their use. The present invention may facilitate long distance transmission at higher than usual wavelengths.

摘要： This invention relates to a high transmission low iron glass that includes boron oxide. The boron oxide, added to this low iron glass, has the effect of improving glass refining, homogeneity and quality (lower seed count) through its flux action and improves glass optical parameters of green and clear glass through the change in refractive index and surface tension. Boron oxide lends to broader and weaker absorption band of such transition element(s) as iron which additionally improves the transmittance of low iron clear glass in certain example embodiments of this invention. In certain example embodiments, the addition of boron oxide in certain quantities in advantageous in that it improves the chemical durability of the glass by decreasing the USPX (or USPXIII) value of the glass via suppression of the silica, sodium ions in the glass structure.
