Title:
LINEAR FORCE SENSING DEVICE
Document Type and Number:
WIPO Patent Application WO1999050630
Kind Code:
A3
Abstract:
The force sensing device (10) of the present invention provides an elastomeric spacer (16) coupled between a base member (12) and platform structure (14). The characteristics of the spacer material allow the spacer (16) to be linearly deformable upon application of force (54), and this deformation region is known as the linear travel distance (50) of the spacer (16). The remaining region has substantially no additional deformation with respect to force (54) applied, and is known as the non-deformable distance (58) of the spacer (16). A sensing mechanism built directly into the device provides a means for sensing the linear travel distance (50) upon various applications of force (54). More specifically, the sensory mechanism includes a movable and fixed portion (32, 34) respectively, separated by a distance equal to the aforementioned linear travel distance (50).
