专利汇可以提供Color sonagrams and methods for their production专利检索，专利查询，专利分析的服务。并且Seismographic signals are separated by filters into their low-, medium-, and high-frequency component signals and the envelope of each is generated and displayed in a different color, e.g., red, green, and blue, respectively. The displays are superimposed, and combined with the seismic trace so as to show both frequency content and time varying amplitude simultaneously.，下面是Color sonagrams and methods for their production专利的具体信息内容。
1. In a process for the display of earth-controlled events, the improvement comprising in combination: a. creating a substantially continuous or discretely sampled electrical signal indicative of said events over an interval of time, b. parallel filtering said electrical signal through at least one filter to separate said signal into a plurality of filtered signals, each representing the component of said signal in a particular band of a continuously varying parameter, c. converting each of said filtered signals into a series of visible lines having excursions, the frequency of said excursions being proportional to the amplitude of said filtered demodulated signal, and representing the intensity of the signal in a particular band of said parameter, averaged over a small, moving time window, d. producing a differently colored replica of each of said set of visible line excursions, e. combining the color replicas corresponding to each signal of said plurality of filtered signals to form a single display indicative of the parameter component distribution of said signal indicative of said earth-controlled events.
2. In a process for the display of earth-controlled transient events, the improvement comprising in combination: a. creating a substantially continuous or discretely sampled electrical signal indicative of said events over an interval of time, b. parallel filtering said electrical signal through at least one filter to separate said signal into a plurality of filtered signals, each representing the component of said signal in a particular band of a continuously-varying parameter, c. demodulating each of said filtered signals to form a corresponding demodulated envelope signal, representing the intensity of the signal in a particular band of said parameter, averaged over a small, moving time window, d. producing a differently colored visible display of each of said demodulated envelope signals wherein the amount of color in a portion of said visible display is proportional to the amplitude of the corresponding portion of said demodulated signal, e. combining the colored displays corresponding to each of said filtered, demodulated envelope signals to form a single display indicative of the amplitude of each of said parameter components of said signal indicative of said earth-controlled event.
3. A process according to claim 1 additionally comprising: f. producing a visible display representative of said electrical signal indicative of said events, g. combining said display representative of said electrical signal indicative of said events with said single display indicative of the time variation in amplitude of each of said parameter components.
4. A process according to claim 2 additionally comprising: h. producing a visible display representative of said electrical signal indicative of said events, i. combining said display representative of said electrical signal indicative of said events with said single display indicative of the time varying amplitude of each of said parameter components.
5. A process according to claim 3 additionally comprising: b''. demodulating each of said filtered signals to form a corresponding demodulated signal.
6. The process of claim 1 wherein each of said visible lines is displayed as a colored transparent line and wherein sAid single display is produced by superimposing two or more sets of colored line displays in registry.
7. The process of claim 2 wherein each of said visible lines is displayed as a colored transparent line and wherein said single display is produced by superimposing two or more sets of colored lines, i.e., individual colored line displays, in registry.
8. The process of claim 3 wherein each of said visible lines is displayed as a colored transparent line and wherein said single display is produced by aligning said colored transparent lines.
9. The process of claim 4 wherein each of said visible lines is displayed as a colored transparent line and wherein said single display is produced by aligning said colored transparent lines.
10. The process of claim 5 wherein each of said visible lines is displayed as a colored transparent line and wherein said single display is produced by aligning said colored transparent lines.
11. A colored display produced according to claim 1.
12. A colored display produced according to claim 2.
13. A colored display produced according to claim 10.
14. The process of claim 1 in which said continuously varying parameter is frequency.
15. The process of claim 2 in which said continuously varying parameter is frequency.
16. The process of claim 1 in which said continuously varying parameter is velocity through the earth or some mathematical function dependent thereon.
17. The process of claim 2 in which said continuously varying parameter is velocity through the earth or some mathematical function dependent thereon.
