Mechanical force components sensing system and an associated method thereof for a magnetically encoded device

摘要

A system includes a device and a contactless inductive force sensing system. The device includes a first band having a first magnetically encoded region with a first magnetic polarity spaced apart from a second magnetically encoded region having a second magnetic polarity. The device further includes a second band having a third magnetically encoded region with the second magnetic polarity spaced apart from a fourth magnetically encoded region having the first magnetic polarity. The contactless inductive force sensing system is used for measuring one or more mechanical force components of the device and generating a mechanical force component signal.
