CALIBRATION SYSTEM FOR A FORCE-SENSING CATHETER
First Claim
1. An apparatus, comprising:
- a rolling element, which is resting on a surface;
a force-sensing device, which is coupled to the surface and is configured to make a first measurement indicative of a force exerted in a direction perpendicular to the surface by a force-sensing probe pressing against the rolling element so as to hold the rolling element stationary; and
a calibration processor, which is configured to collect the first measurement from the sensing device, to collect a second measurement indicative of the force from the force-sensing probe, and to calibrate the force-sensing probe based on the first and second measurements.

Abstract
An apparatus, consisting of a rolling element, which is resting on a surface, and a force-sensing device, which is coupled to the surface. The force-sensing device is configured to make a first measurement indicative of a force exerted in a direction perpendicular to the surface. The force is exerted by a force-sensing probe pressing against the rolling element so as to hold the rolling element stationary. The apparatus further includes a calibration processor, which is configured to collect the first measurement from the sensing device, to collect a second measurement indicative of the force from the force-sensing probe, and to calibrate the force-sensing probe based on the first and second measurements.

14. A method, comprising:
-
positioning a rolling element on a surface coupled to a force-sensing device; pressing a force-sensing probe against the rolling element so as to hold the rolling element stationary on the surface while exerting, through the rolling element, a force on the force-sensing device in a direction perpendicular to the surface; while pressing the force-sensing probe, making first and second measurements of the force using the force-sensing device and the probe, respectively; and calibrating the force-sensing probe based on the first and second measurements. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
