    • A method of distributing a quantum key from a sender to a recipient. The recipient generates a pulse having multiple photons; splits the pulse into first and second sub-pulses; phase modulates the first sub-pulse with a secret key; and transmits both the phase-modulated first sub-pulse and the second sub-pulse to the sender. The sender receives the phase-modulated first sub-pulse and the second sub-pulse from the recipient; encodes a quantum key bit into one of the sub-pulses received from the recipient; and transmits both the phase-modulated first sub-pulse and the second sub-pulse back to the recipient. Then, the recipient receives the phase-modulated first sub-pulse and the second sub-pulse from the sender; phase modulates the second sub-pulse with the secret key; combines the phase-modulated first sub-pulse and the phase-modulated second sub-pulse to produce a composite pulse; and processes the composite pulse in an attempt to detect the quantum key bit.
    • 将量子密钥从发送方分发到接收方的方法。 接收者产生具有多个光子的脉冲; 将脉冲分为第一和第二子脉冲; 用秘密密钥对第一子脉冲进行相位调制; 并将相位调制的第一子脉冲和第二子脉冲发送到发送器。 发送方从接收方接收相位调制的第一子脉冲和第二子脉冲; 将量子密钥位编码为从接收者接收的子脉冲之一; 并将相位调制的第一子脉冲和第二子脉冲发送回接收器。 然后,接收者从发送者接收相位调制的第一子脉冲和第二子脉冲; 用秘密密钥对第二子脉冲进行相位调制; 组合相位调制的第一子脉冲和相位调制的第二子脉冲以产生复合脉冲; 并处理复合脉冲以试图检测量子密钥位。

    • A yieldable prop having a first end and a second end includes a first hollow conduit, a second conduit slidably received in the first hollow conduit, and a clamp assembly positioned adjacent the juncture of the first hollow conduit and the second conduit. A yield section is provided at the end of the first and/or second conduits, or at the juncture of the first and second conduits. The yield section includes a shroud spaced from an inner pipe to provide a space to receive a collapsible insert. An end of a conduit is positioned in the space and compresses the insert when the compressive load on the prop exceeds the compressive load capacity of the insert.
    • 具有第一端和第二端的可屈服支撑件包括第一空心管道,可滑动地容纳在第一中空管道中的第二管道和邻近第一中空管道和第二管道的接合部定位的夹具组件。 屈服部分设置在第一和/或第二导管的末端,或在第一和第二导管的接合处。 产量部分包括与内管间隔开的护罩,以提供容纳可折叠插入物的空间。 当支柱上的压缩载荷超过插入件的压缩载荷能力时,导管的端部定位在该空间中并压缩插入件。

    • A truss shoe for a roof support system includes a base member having a bearing surface and, optionally, an end having a sweeping radius for ease of moving the truss shoe into an installation position, a bolt receiving section having a bore hole, a cable engaging section, and an intermediate section. The cable engaging section includes an opening and a slot and, optionally, a lock-in device that allows a cable to move through the slot into the opening and retains the cable in the opening. In another non-limiting embodiment of the cable engaging section, the cable is moved into an assembly mounted in a conical-shaped passageway of the cable engaging section to compress the assembly around the cable. The intermediate portion includes a pair of side flanges on the base member between the bore and the opening and, optionally, a rib between the pair of side flanges.
