    • 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.

    • A method of accessing in an equipment of a communication network is proposed in the invention. The method comprises the steps of: receiving a message 2 from a base station, the message 2 being used for an assignment of resource to transmit a message 3, the assigned resource corresponding to N HARQ RTTs, where 1≤N≤8; and transmitting the message 3 only in part of the N HARQ RTTs. With the scheme of the invention, a MTC device selectively transmits the Msg3 in one/some HARQ RTT and maintains silence in another one/some HARQ RTT, thus the possibility of the occurrence of access collision with other UEs may be backed off, such that other UEs, particularly human-to-human UEs, may transmit the Msg3 normally. And the possibility of the occurrence of collision is reduced from the viewpoint of the user equipments in a network, reducing entirely the possibility of an access delay and access failure.
    • 本发明提出了一种在通信网络的设备中进行访问的方法。 该方法包括以下步骤:从基站接收消息2,消息2用于分配资源以发送消息3,所分配的资源对应于N个HARQ RTT,其中1 = N = 8; 并且仅在N个HARQ RTT的一部分中发送消息3。 利用本发明的方案,MTC设备选择性地在一个/某个HARQ RTT中发送Msg3,并且在另一个/一些HARQ RTT中保持静默,因此可能会退出与其他UE发生访问冲突的可能性,使得 其他UE,特别是人对人类UE可以正常地发送Msg3。 并且,从网络中的用户设备的观点来看,发生冲突的可能性降低,从而完全减少了访问延迟和访问失败的可能性。
