摘要： A method for measuring the electromagnetic response of formations below the bottom of a body of water includes positioning at least one electromagnetic transmitter and at least one electromagnetic receiver in the body of water each at a selected depth below the water surface. A transient electric current is passed through the at least one transmitter. An electromagnetic signal is detected at the at least one electromagnetic receiver. The depths are selected so that substantially all electromagnetic response to the current passed through the transmitter from the air above the body of water in the detected electromagnetic signal occurs before the beginning of a response originating in the formations below the water bottom.

摘要： A method for determining resistivity distribution of formations below a bottom of a body of water from transient electromagnetic signals acquired by imparting a transient electromagnetic field into the water and detecting an electromagnetic response thereto at a plurality of spaced apart positions from a place of the imparting includes simulating an air wave response at each of the plurality of spaced apart positions. The simulated air wave response is subtracted from the detected response to produce a subsurface impulse response at each of the plurality of positions. The subsurface impulse responses are used to determine the resistivity distribution.

摘要： A method for attenuating correlated noise in transient electromagnetic survey signals includes producing, from a transient electromagnetic signal measured by a first receiver, an estimate of the Earth response and an estimate of the correlated noise from a portion of the signal occurring before onset of an Earth response, and/or after the Earth response has substantially decayed. An estimate of the correlated noise is determined over the entire measured signal from the first receiver using the estimate of the Earth response. The noise estimate from the entire signal and the portion estimate are used to estimate correlated noise in transient signals from at least a second receiver.

摘要： Accelerations of a probe or probe head due to vibrations of a machine during a measuring operation are measured using accelerometers placed in the probe or probe head. The acceleration signals are double integrated to determine the corresponding displacements of the probe or probe head and these are added to the readings of displacement of the machine taken from the machine scales using a data fusion algorithm to correct the scale readings for the vibration of the probe. Both linear and angular accelerations of the probe can be corrected in this way.

摘要： A spring loading system achieves substantially zero-rate by winding an unstressed, say flat, spring strip onto a former of constant curvature so as to pass from the unstressed state through a region of predetermined shape to conform with the former. The net energy expended/released in winding/unwinding the strip is directly related to the amount of strip wound onto/off the former, whatever the total length of strip wound. The system is coupled to a driven member by an inextensible string wound on the former in opposition to the spring which is held in tension by the torque exerted on the former by the wound spring.
