摘要： Separate electrical timing and load activation devices are provided for each of plural electrical loads and each device is connected to receive reference timing signals from a central unit. Each of the separate timing and load activation devices measures a reference time interval accurately defined by the reference timing signals and subsequently activates its associated electrical load after a respectively corresponding predetermined time delay which is determined as a function of the locally measured reference time interval.

摘要： A method and apparatus for controlling the firing of a seismic source, wherein the firing circuit is coupled to the source by a two-conductor cable whose impedence is changed upon firing of the source. The change in cable impedence is detected and the time delay between the firing command signal and the detected change is used to control the firing command signal in order that a plurality of sources may be fired in a desired sequence.

摘要： A method controls a delay of an air-gun in an aquatic seismic source. The method includes a step of receiving an attribute of the air-gun during the aquatic seismic survey; a step of calculating, based on a time-delay algorithm that uses the attribute, the asynchronization time of the air-gun; a step of determining whether the asynchronization time is smaller than a given time threshold; a step of instructing a controller to (1) wait for a predetermined time before calculating again the asynchronization time of the air-gun if the asynchronization time is smaller than the given time threshold, or (2) calculate an updated asynchronization time for the air-gun based on the attribute if the asynchronization time is larger than the given time threshold; and a step of sending the updated asynchronization time to a gun controller of the air-gun for adjusting a delay time for firing the air-gun.

摘要： The present invention relates to a method for initiating an underwater implosive seismic source which comprises the steps of: measuring the instantaneous pressure at the location of the source; determining, from this measured pressure, the bubble period separating the firing signal from the implosion peak of the shock wave; and initiating the source with a delay or advance of a value equal to the difference between the bubble period corresponding to the instantaneous pressure and that corresponding to the mean pressure. The invention also provides a device for carrying out this method which device comprises; means for measuring the instantaneous pressure in the neighborhood of the source; comparator means (C5) for comparing this pressure with a mean value; and time delay means (C3, C4) for delaying a firing signal (S1) by a value which is a function of the result of this comparison.

摘要： Solid-state electronic system for use in timing precisely the detonation of a plurality of explosive charges in order to shape a seismic energy pulse produced thereby. It has a firing circuit for each of the blasting caps that are associated with the explosive charges. And, there are time-delay selection circuits controlling all after the first charge in order to preselect the delays for producing a desired effective shape of the total seismic energy shock created. The time delays are accomplished by counting pulses derived from a crystal-controlled oscillator.
