摘要： A laser diode (22) emits laser light which is collimated into parallel rays with collimating lens (24). The collimated beams travels as much as 50 meters or more before being reflected back to a photoreceiver (28). A ball lens (26) focuses the reflected light onto the photoreceiver. The photoreceiver, preferably, is a synchronous detector which issues control pulses to a laser drive circuit (42) for causing the laser diode to emit intermittent bursts of laser light. The synchronous detector then compares the timing of received light with the timing of the control pulses to the laser diode to distinguish between true reflected light and stray light. An intensity adjustment (56) adjusts the intensity of the laser light in accordance with a distance between the laser diode/photoreceiver and a reflector. In this manner, distances of 1-70 meters can be accommodated with no lens modification. A reference voltage (48) proportional to the intensity of the laser light is used in a gated feedback (46) for faster response times.
摘要翻译：激光二极管（22）发射激光，其与准直透镜（24）准直成平行光。准直光束在被反射回光接收器（28）之前行进多达50米或更多。球透镜（26）将反射光聚焦到光接收器上。光接收器优选地是向激光驱动电路（42）发出控制脉冲以使激光二极管发射间歇的激光脉冲的同步检测器。然后，同步检波器将接收的光的定时与控制脉冲的定时相比较，以分辨真实的反射光和杂散光。强度调节（56）根据激光二极管/光接收器和反射器之间的距离来调节激光的强度。以这种方式，可以容纳1-70米的距离，而不需要镜头修改。在门控反馈（46）中使用与激光强度成比例的参考电压（48），以实现更快的响应时间。

摘要： A vacuum-formed lid for a large drinks container is disclosed made from extruded sheet plastic. The lid has provision for the user to remove a tear-out portion to leave a hole through which liquid may be poured out of the container. The lid includes a ridge which is gripped between finger and thumb. A slit is located just under the thumb, so that squeezing the ridge is effective to open the slit. The slit runs across the "grain" of the extruded plastic. The effect is that tearing the lid can be easily accomplished, yet the tear may be directed and controlled easily.
摘要翻译：公开了一种用于大型饮料容器的真空成型盖，其由挤出片状塑料制成。盖子具有用于使用者移除撕出部分以留下可以将液体从容器中注出的孔。盖子包括夹在手指和拇指之间的脊。狭缝位于拇指下方，因此挤压脊可有效打开狭缝。狭缝穿过挤出的塑料的“颗粒”。效果是可以容易地实现撕裂盖子，但是可以容易地引导和控制撕裂。

摘要： Apparatus for non-invasively inspecting an object, such as an item of luggage, for explosives material comprises a multi-channel thermal neutron inspection system having a plurality of neutron irradiation chambers. Simultaneous operation of several channels increases maximum system throughout several times. Each chamber has a lithium neutron source which is stimulated to neutron production by a proton beam. Beam switching magnets are energized by pulsing to divert a common proton beam to each source in turn. The initial beam is generated by a radio frequency quadrupole accelerator. The advantages of this system are very low residual source activity and controllable neutron production thereby minimizing safety hazards. The irradiation chamber may contain several different gamma ray detectors to identify the presence elements present in explosives material. In addition a neutron radiography imaging means may be employed to identify the presence of potential shielding materials.
