摘要： A detonator which is responsive to a shock tube event which is validated if a link is fused at a predetermined time interval after a light signal produced by the event is detected and if, at the end of a subsequent time interval, the link is still fused and the light signal is absent.

摘要： A method of communicating through the earth which includes the steps of using a digital pulse train to generate a sweep pulse train which controls the frequency of a magnetic field at a first location, and at a second location, detecting the magnetic field and producing a signal at a frequency dependent on the frequency of the sweep pulse train, and extracting a replica of the digital pulse train from the signal.
