    摘要： A roller door apparatus is provided that includes a roller means and a means journalling the roller means for reversible rotation about a central longitudinal roller axis. The roller door also includes end rail means for a reciprocal linear movement between a first position adjacent the roller means and a second position away from the roller means. Also included is a flexible curtain means with one end attached to the end rail means and the other end attached to the roller means, such that the curtain means closes a door opening with the end rail means in the second position. The curtain means winds onto the roller means when the end rail moves from the second position to the first position and vice versa. The roller door further includes a reversible electric drive motor means coupled to the roller means, and an electrical control means for controlling the drive means during movement of the end rail means for rapid acceleration of the curtain means during an initial portion of each movement, and for control of declaration of the curtain means to zero velocity during a final portion of each movement.

    摘要： A method and system for determining alarm conditions of a slope under inspection whereby one or more dimensionless threat estimate values are calculated for one or more time periods. The maximum dimensionless threat estimate value calculated is selected and compared with a threshold alarm value. If the maximum dimensionless threat estimate value exceeds the threshold alarm value alarm conditions are set to indicate that the slope under inspection is exhibiting unsafe movement.

    摘要： A method of generating an alarm indicating movement of a slope under inspection that sets an alarm if (1), where dX is a first measured displacement, dY is another measured displacement at a chosen difference from dX, and dZ is another measured displacement at a chosen difference from dY, and the corresponding times at which the chosen distances are measured are tA, tB and tC respectively for dX dY and dZ. So that an alarm is set if the ratio of the time taken for the slope to move between dY and dZ compared to moving between dX and dY is less than the ratio of the respective displacements. t C - t B t B - t A

    摘要： A slope monitoring system having a radar and a video camera recording images sequences of the slope. A data processing unit performs coordinate registration to align the radar images and the video images. Interferometry is used to detect movement in the slope by generating interference maps between the images. These are suitably phase maps showing the phase change between a radar image and a reference image. An alarm occurs if a significant movement is detected.

    摘要： A ground penetrating radar includes a signal generator, a return signal processor, a gate and an antenna. The signal generator is a dual frequency synthesizer that generates a stepped frequency master signal and a tracking signal offset by an intermediate frequency. The return signal processor is a dual channel quadrature receiver that mixes down a return signal and a sample of the master signal to intermediate frequency using the tracking signal. The signal generator is pulsed by the gate and the return signal is gated at the same frequency. Hollow pyramidal antennas are also described that have an ultrawide band bowtie structure with antenna electronics located within one antenna element. A method of operating the radar is also described.
