摘要： Drill bits and methods for sampling sensor data associated with a state of a drill bit are disclosed. A drill bit for drilling a subterranean formation comprises a bit configured for receiving a data analysis module. The data analysis module comprises at least one sensor, a memory, and a processor. The processor is configured for executing computer instructions to filter information derived from sensor data in the drill bit to develop a piecewise polynomial curve of the sensor data. Filtering information derived for the sensor data comprises approximating a first derivative of a sensor data waveform, calculating a plurality of zeros for the first derivative of the sensor data waveform, and fitting a cubic polynomial between adjacent zeros calculated from the first derivative of the sensor data waveform resulting in a piecewise cubic polynomial.

摘要： A spindle assembly for supporting a drill bit for repair. The spindle assembly includes a plurality of stepped segments of ever-decreasing diameter above a base, each segment sized to be received in a bore of a service cap inserted in the shank of a bit to be repaired. An end-cap for carrying an electronics module includes an end-cap body comprising a bore of similar diameter to the service cap bore diameter, but having one or more lugs protruding radially thereinto to prevent a spindle segment from entering the end cap bore so that the drill bit cannot be supported on the spindle.
