ABSTRACT: Real-Time Tracer Monitoring of Reservoir Stimulation Procedures via Electronic Wireline and Telemetry Data Transmission

The skin tunnel transformer. A new system that permits both high efficiency transfer of power and telemetry of data through the intact skin.

Artificial organs which are to be chronically implanted require a means of getting power into the body from an external power source with minimum risk of infection and irritation to the skin. The skin tunnel transformer is such a device whereby high level electromagnetic energy can be transmitted through the skin with very low losses and noncritical positioning. Two versions of the transformer are shown and described, and experimental results obtained with dogs are presented. Transmission over 50 watts at better than 95 percent efficiency has been accomplished with no ill effects. The use of the transformer for simultaneous transmission of telemetry data is also discussed.

Digital Video Data Transmission System for Photometric Television

A television system to measure broadband spectral intensities of stars and their coordinates has been developed for an experiment in the Orbiting Astronomical Observatory. The satellite provides three different methods of telemetry data transmission, but none of them is really suited for video transmission: real-time digital transmission is too slow; on-board data storage has too small a capacity; and real-time analog transmission is not sufficiently accurate. By development of special digital scan techniques for television, real-time data processing on board became feasible, and real-time digital video transmission was chosen as the prime mode. Also, additional small modifications of the television system made it possible to utilize the other two remaining available methods for video transmission as backup modes of operation. The particular technique is applicable to many space experiments, and many existing satellites can be converted to a television carrier without major modification.
