BOREHOLE MEASUREMENT WHILE DRILLING SYSTEMS and METHODS Abstract of the Disclosure Disclosed are improvements pertaining to measurement while drilling apparatus, methods, and systems, including: generation of mud pulse pressure variations in a regime of hydraulic shock waves; transmission of information carrying signals via mud pressure variations which in- clude various interfering signals generally termed "noise" and employing special techniques involving digital filters for accomplishing reception of said information carrying signals; providing hydraulic means to automatically effect periodic closing of the valve means that produces the in- formation carrying signals; providing electrical means to inhibit valve means operation in case of electrical fail- ure in downhole apparatus; providing means which serve to greatly increase the number of satisfactory actuations of said valve means attainable without downhole battery re- charge or replacement; providing unique pulse time codes which permit substantial increase in rate of information transmission and the accuracy and precision of such trans- mission.
