Abstract
Abstract A cathode ray tube is used for quality control in conjunction with a method and apparatus for monitoring seismic data gathers. As seismic reflection data is acquired, it is displayed on a cathode ray tube and visually monitored to determine whether information channels are to be deleted due to excess noise, improper amplification, etc., prior to recording the acquired data.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
116 words
In a seismic data acquisition system including a receiver for receiving and processing seismic data signals from a plurality of channels and a recorder connected to the output of the receiver for recording the seismic data signals, a monitor display comprising: first means connected to the output of the receiver for converting each seismic data signal from each channel to an amplitude signal by integrating said each seismic data signal; second means for associating each channel of said plurality of channels with a display location; and display means connected to said first means and said second means for displaying said amplitude signal at a display location corresponding to each channel before recording said seismic data signals.
Claim 2
Dependent Claim
116 words
In a seismic data acquisition system including a receiver for receiving and processing seismic data signals from a plurality of channels and a recorder connected to the output of the receiver for recording the seismic data signals, a monitor display comprising: first means connected to the output of the receiver for converting each seismic data signal from each channel to an amplitude signal by integrating said each seismic data signal; second means for associating each channel of said plurality of channels with a display location; and display means connected to said first means and said second means for displaying said amplitude signal at a display location corresponding to each channel before recording said seismic data signals.
Claim 3
Dependent Claim
20 words
The monitor display according to claim 1 also including means for selecting a predetermined number of said plurality of channels.
Claim 4
Dependent Claim
30 words
The monitor display of claim 2 also including intensity means connected to said display means for controlling the intensity of said amplitude signal of each of said seismic data signals.
Claim 5
Dependent Claim
26 words

Claim 10
Dependent Claim
37 words
The monitor display according to claim 1 also including: status means connected to said display means for determining status information of said display means; and report means connected to said status means for transmitting said status information.
Claim 11
Independent Claim
52 words
A method for monitoring seismic data signals as they are received prior to recording including the steps of: converting seismic data signals to amplitude signals by integrating said seismic data signals; converting channel locations for said seismic data signals to display locations; and displaying said amplitude signals corresponding to said display locations.
Claim 12
Independent Claim
52 words
A method for monitoring seismic data signals as they are received prior to recording including the steps of: converting seismic data signals to amplitude signals by integrating said seismic data signals; converting channel locations for said seismic data signals to display locations; and displaying said amplitude signals corresponding to said display locations.
