    • A system, apparatus and method provide wireless communications to a geographical area. The system includes at least one atmospheric platform serving as a central relay or node using a star network topology for the geographic area. The atmospheric platform carries a payload that comprises communications equipment. The system further includes a plurality of user equipment units located within the geographic area and at least one ground station or gateway for providing an information pathway between the user equipment units. The gateway has network processing and switching equipment for routing the information between the users. A wireless trunkline carries signals between the gateway and the atmospheric platform. The apparatus and method comprise gateway and payload uplink portions and downlink portions. The downlink portions aggregates and de-aggregates user generated information from the platform to the gateway. The uplink portions de-aggregate and aggregate the information and route the information with the network switching equipment to intended user equipment units, from the gateway to the platform. The gateway may also provide information pathways from the platform to user equipment units outside of the geographic area through existing communications infrastructure. The system, apparatus and method utilize a wide, non-contiguous band of spectrum in point-to-point links to carry the combined signal traffic from a multitude of subscribers on the ground to the communications switches at the gateway and vice versa, via the airborne platform. The use of wireless trunklines enables all types of switching, including circuit, cell, packet, or frame, or any combination thereof, to be performed by standard equipment housed in facilities on the ground rather than by specially designed equipment located on the airborne platform.
    • 系统,装置和方法向地理区域提供无线通信。 该系统包括至少一个大气平台,用作中央中继或节点,使用星形网络拓扑进行地理区域。 大气平台载有包含通信设备的有效载荷。 该系统还包括位于地理区域内的多个用户设备单元和用于在用户设备单元之间提供信息路径的至少一个地面站或网关。 网关具有用于在用户之间路由信息的网络处理和交换设备。 无线干线在网关和大气平台之间传送信号。 该装置和方法包括网关和有效载荷上行链路部分和下行链路部分 下行链路部分聚合并将用户生成的信息从平台聚合到网关。 上行链路部分对信息进行聚合和聚合,并将网络交换设备的信息从网关到平台路由到预定的用户设备单元。 网关还可以通过现有的通信基础设施提供从平台到地理区域之外的用户设备单元的信息路径。 该系统,装置和方法利用点对点链路中宽的非相邻频带,将来自地面上的多个用户的组合信号业务从网关传送到通信交换机,反之亦然。 机载平台 使用无线干线使所有类型的交换(包括电路,信元,分组或帧或其任何组合)由位于地面设施中的标准设备而不是位于机载平台上的专门设计的设备来执行。

    • A reusable grinding tool consisting of a replaceable single layer of abrasive particles intimately bonded to a precisely configured tool substrate, and a process for manufacturing the grinding tool. The tool substrate may be ceramic or metal and the abrasive particles are preferably diamond, but may be cubic boron nitride. The manufacturing process involves: coating a configured tool substrate with layers of metals, such as titanium, copper and titanium, by physical vapor deposition (PVD); applying the abrasive particles to the coated surface by a slurry technique; and brazing the abrasive particles to the tool substrate by alloying the metal layers. The precision control of the composition and thickness of the metal layers enables the bonding of a single layer or several layers of micron size abrasive particles to the tool surface. By the incorporation of an easily dissolved metal layer in the composition such allows the removal and replacement of the abrasive particles, thereby providing a process for replenishing a precisely machined grinding tool with fine abrasive particles, thus greatly reducing costs as compared to replacing expensive grinding tools.
    • 可重复使用的研磨工具由紧密结合到精确配置的工具基底上的可更换单层研磨颗粒组成,以及用于制造研磨工具的方法。 工具衬底可以是陶瓷或金属,并且磨料颗粒优选是金刚石,但是可以是立方氮化硼。 制造过程包括:通过物理气相沉积(PVD)将配置有金属层(例如钛,铜和钛)的工具衬底涂覆; 通过浆料技术将磨料颗粒施加到涂覆表面; 并通过使金属层合金化将磨料颗粒钎焊到工具基底上。 金属层的组成和厚度的精确控制使得能够将单层或几层微米级磨料颗粒结合到工具表面。 通过在组合物中引入容易溶解的金属层可以使磨料颗粒的移除和更换,从而提供了用精细磨料颗粒补充精密加工的磨削工具的方法,从而与替代昂贵的磨具相比大大降低了成本 。
