    • A light-tight and collapsible chamber (120, 300) for use in demonstrating the optical performance of a piece of retroreflective sheeting placed within the chamber (120, 300) is provided. The chamber (120, 300) comprises a generally opaque polygonal back panel (130, 320) having a plurality of edges; a plurality of generally opaque side panels (140, 170) wherein adjacent side panels (140, 170) are attached to one another to form a light-tight connection and each of the plurality of opaque side panels (140, 170) are attached along and positioned essentially perpendicular to one of the plurality of edges of the back panel (130, 320) to form a light-tight connection; and an open area (150, 330) essentially parallel to and distanced from the back panel (130, 320) and forming an observation window permitting an observer to view the piece of retroreflective sheeting positioned within the chamber (120, 300). In one embodiment, the chamber (120, 300) further comprises a leaflet (310) capable of attaching to the piece of retroreflective sheeting attached to the back panel (130, 320). In another embodiment, the chamber (120, 300) can be collapsed in various ways.
    • 提供了用于证明放置在腔室(120,300)内的一片回射片材的光学性能的不透光和可折叠腔室(120,300)。 腔室(120,300)包括具有多个边缘的大致不透明的多边形后面板(130,320); 多个通常不透明的侧板(140,170),其中相邻的侧板(140,170)彼此附接以形成不透光连接,并且所述多个不透明侧板(140,170)中的每一个沿着 并且基本上垂直于后面板(130,320)的多个边缘中的一个定位,以形成不透光的连接; 以及基本上平行于所述后面板(130,320)并远离的开放区域(150,330),并且形成允许观察者观察位于所述腔室(120,300)内的所述回射片材的观察窗口。 在一个实施例中,腔室(120,300)还包括能够附接到附接到后面板(130,320)的一片后向反射片材的小叶片(310)。 在另一个实施例中,腔室(120,300)可以以各种方式折叠。

    • A method is provided for communications in a cellular network (1) comprising a plurality of mobile stations (MS1 to MS3) adapted for performing wireless communications with at least one base station (BS1, BS2) using a first transmission technology, the method comprising: forming a cooperating cluster (C) comprising two or more of the mobile stations (MS1, MS2), and performing short-range communications between the mobile stations (MS1, MS2) of the cooperating cluster (C) using a second transmission technology being different from the first transmission technology for improving, for at least one mobile station (MS1, MS2) of the cluster (C), the performance of the wireless communications with the base station (BS), preferably by using MIMO techniques for at least one of interference suppression and cancellation, in particular by using at least one of transmit pre-coding for uplink transmissions and receive antenna weighting for downlink reception. A mobile station (MS1, MS2) for forming a cooperating cluster (C), a cooperating cluster (C) comprising at least one such mobile station (MS1, MS2), and a cellular network (1 ) are also provided.
    • 提供了一种用于蜂窝网络(1)中的通信的方法,所述蜂窝网络(1)包括适于使用第一传输技术与至少一个基站(BS1,BS2)进行无线通信的多个移动站(MS1至MS3),所述方法包括: 形成包括两个或更多个移动站(MS1,MS2)的协作簇(C),并且使用不同的第二传输技术在协作簇(C)的移动站(MS1,MS2)之间执行短距离通信 从用于改进集群(C)的至少一个移动站(MS1,MS2)的第一传输技术来看,优选地通过使用MIMO技术来执行与基站(BS)的无线通信, 干扰抑制和消除,特别是通过使用用于上行链路传输的发送预编码和用于下行链路接收的接收天线加权中的至少一个。 还提供了用于形成协作簇(C)的移动台(MS1,MS2),包括至少一个这样的移动站(MS1,MS2)和蜂窝网络(1)的协作簇(C)。
