Title: Method for determining position with improved calibration
Inventor: CLOSE DAVID
IPC: E21B47/09
Filed: 2017-06-08
Granted: 2019-08-20
Abstract: The method and system for determining position with improved calibration allows a device to initiate activity at the proper location, such as navigating a drill bit through a rock formation. A position sensor (30) having an oscillation element with a range of displacement in a set direction according to gravity generates a position data signal based on an amount of displacement in the set direction. A temperature sensor (40) detects temperature and duration of the temperature. A plastic bias value is determined by a processor module (50) based on the temperature data signal, the duration of the temperature, and the position data signal so as to account for bias and hysteresis errors. A position value is set according to the plastic bias value so that the position value is more accurate. The activity of the terminal device is initiated or maintained according to the position value calibrated by the plastic bias value.

Abstract: Non-destructive read out (NDRO) circuits are provided for use in reciprocal quantum logic (RQL) superconducting systems. Each NDRO circuit includes a "body" circuit that provides a single or multi-state sub-critical bias current to one or many independent "tail" circuitries. Each "tail" has minimal effect on the "body" thereby preventing any interference or destruction to the state of the "body" circuitry. The circuits reduce device count and thereby increase circuit density, simplify and reduce the cost of fabrication, and provide functionality not available in existing designs, such as the ability to write a state and read it in the same operation cycle. The NDRO circuits provide more compact unit cells useful in memory or logic arrays, demanding fewer resources with increased functionality. The circuits also provide compact cells for AND, AND-OR, A-NOT-B, inverter, multiplexer, and demultiplexer gates.
