摘要： Embodiments of the present invention provide a continuum manipulator that can be used, for example, as a steerable catheter tip. The manipulator of the embodiments comprises a plurality of segments arranged in a stack, which is then able to bend in a range of directions away from the long axis of the stack. In one embodiment the segments include a helical portion which winds in the direction of the long axis of the stack, and can thus bend away from the long axis in any direction. In some embodiments a carbon fiber rod is included as a backbone for the stack, to minimize hysteresis and improve repeatability of bending. In addition, in embodiments of the invention tendon control channels are provided formed within the segments, through which tendon control wires extend to apply compression and/or bending forces to the stack.

摘要： Embodiments of the invention provide an arrangement where a small detection coil of an NQR system is mounted on the end of a carrier such as a prodder stick, and is then carried by the carrier into the very near vicinity of, and more particularly for example into contact with, a possible target explosive device. Because the detection coil is brought into contact with or into the very near vicinity of the target, the transmitted NQR signals, and the resultant QR response, can be much lower power, to the extent that such a system can be made fully man-portable, and also be much lower cost to manufacture. As a consequence, NQR explosive detections systems may be deployed in larger numbers than has heretofore been possible, thus increasing the certainty of, and hence safety, of landmine detection, and improving clearance rates.
