Abstract
A method and system for determining distance from a conductor. A signal is infused into object or into a body part. Calibration occurs by moving the object to at least two known distances and measuring the signal. Using the measured signals, a signal-to-distance map can be created and used to determine the distances of additional objects or body parts.
Claims20
A method of sensing a range of a conductive object from a conductor, comprising:
- generating a first signal;
- infusing the first signal into the conductive object;
- moving the conductive object to a first known distance from the conductor;
- detecting the first signal at the conductor during a first time period;
- determining a first measurement of the detected first signal taken during the first time period;
- moving the conductive object to a second known distance from the conductor;
- detecting the first signal at the conductor during a second time period;
- determining a second measurement of the first signal taken during the second time period;
- calculating a signal-to-distance map based on the first measurement and the second measurement;
- sensing a second signal at the conductor during a third time period;
- and
- determining a range based on the second signal sensed during the third time period and the signal-to-distance map.
