    Abstract: A method to measure a parameter of interest is provided. The method includes receiving a first signal via an antenna of a reception circuit. The method further includes generating a second signal by a signal generator of the reception circuit. The method further includes mixing the first signal and the second signal in a mixer of the reception circuit to generate a third signal. The method further includes measuring a parameter of the third signal using an instrument. The method further includes adjusting, by a processor, a frequency of the second signal to substantially match a frequency of the first signal based at least in part on the measured parameter of the third signal. The method further includes determining, by the processor, the parameter of interest using the adjusted frequency of the second signal.

    Abstract: An apparatus for measuring resistivity in a borehole includes first and second modules configured to be conveyed through the borehole and a transmitter connected to the first module, the transmitter transmitting a transmitter signal that causes a field signal to be created in a formation surrounding the borehole. The apparatus also includes a receiver connected to the second module configured to sense the field signal, a reflection generator and a delay determination circuit that includes a pulse generator and a timer. The apparatus also includes a communication link coupling the delay determination circuit and the reflection generator. The delay determination circuit causes a first pulse to be transmitted to the reflection generator and determines an indication that is related to the time until a reflection is received back from the reflection generator.

    Abstract: A system for determining bending of a drilling tool includes at least one element attached to the drilling tool and the at least one element includes a magnetic material, and at least one electrical conduit in the drilling tool and electro-magnetically coupled to the at least one element. The system also includes at least one signal source that feeds a signal into the electrical conduit and a measurement system that: measures at least one property of the signal in the electrical conduit as the signal source feeds the signal; and determines the bending of the drilling tool based on the measured property of the signal.

    Abstract: Method and apparatus for transmitting a first data set from a tool to a receiver are provided. The method includes: obtaining a first plurality of measurements using the tool to form a first dataset; saving data from the first plurality of measurements that form the first dataset in non-volatile memory; transmitting first data-groups derived from the first dataset to the receiver, each of the first data-groups comprising different measurements of the formation; and storing in the non-volatile memory a storage position of a last transmitted first data-group. Upon restoration of a loss of communications that prevents transmission of all the first data-groups, determining the storage position of the last transmitted first data-group; and continuing the transmission of the first data-groups from the storage position of the first data-group last transmitted before the loss of communications.
