    • The invention provides an apparatus and method for fill level monitoring in which the height of contents in a container (10) is monitored. The apparatus comprises an ultrasound reciever (30) and signal processing means (50-56) adapted to receive signals from the receiver, the arrangement being such that the signal processing means (50-56) identifies a first signal (32), in use, which is representative of a wavefront (26) transmitted through the contents of the container (10) independently of the height of the contents in the container (10), and a second signal (34) that is representative of a wavefront (24) that is reflected from the interface (22) between the surface of the contents in the container (10) and the environment above the contents, and in which the signal processing means (50-56) uses the difference in travel time for the two wavefronts (24, 26) to provide a measurement of the level of the contents in the container (10). A plasma generation system comprising a pulsed laser (99) and a target (101) in front of the container (102) is also disclosed, the plasma (103) creating ultrasound in the container (102).

    • A method of geophysical prospecting for detecting bodies of fluids in underground formations comprises the steps of activating a seismic energy source (2) to transmit seismic energy into the ground, detecting an electromagnetic signal (14) generated by interaction between the seismic energy and underground formations (12) including fluids, and recording properties of the detected electromagnetic signal against time, so as to record an electromagnetic signal generated by interaction between a secondary energy impulse (10) from the activation of the energy source and underground formations including fluids. The secondary energy impulse propagates to the formations more slowly than the primary seismic waves from the same activation of the energy source travelling at the speed of sound as attenuated by the materials through which they pass. The detected electromagnetic signal comprises frequencies in the range 0 to 30 Hz. Recorded signals may then be processed to correlate them with the depth and thickness of fluid-containing underground formations with which the secondary energy impulse interacts to generate the electromagnetic waves.
    • 一种用于检测地下构造中的流体物体的地球物理勘探方法包括以下步骤:激活地震能量源(2)以将地震能量传递到地面中,检测由地震能量与地下地层之间的相互作用产生的电磁信号(14) (12),并且根据时间记录检测到的电磁信号的记录特性,以便记录由能量源的激活和包括流体的地层之间的二次能量脉冲(10)之间的相互作用产生的电磁信号。 二次能量冲击比起原始地震波慢慢地传播到能量源的相同激活下,以能够通过它们通过的材料衰减的声速传播。 检测到的电磁信号包括0至30Hz范围内的频率。 然后可以处理记录的信号以使它们与含有流体的地下地层的深度和厚度相关联,二次能量脉冲与之相互作用以产生电磁波。
