Load transducer and force measurement assembly using the same
First Claim
1. A load transducer comprising, in combination:
- a plurality of beam portions connected to one another in succession, the plurality of beam portions being arranged in a circumscribing pattern whereby a central one of the plurality of beam portions is at least partially circumscribed by one or more outer ones of the plurality of beam portions, a first one of the plurality of beam portions having a first surface and a second one of the plurality of beam portions having a second surface, the first surface being disposed at an angle relative to the second surface; and
at least one load cell disposed on one or more of the plurality of beam portions, the at least one load cell configured to measure at least one force or moment component of a load applied to the load transducer, the at least one load cell including a first deformation sensing element disposed on the first surface and a second deformation sensing element disposed on the second surface.

20. A force measurement assembly comprising, in combination:
-
at least one plate component having a measurement surface for receiving a portion of a body of a subject; and a plurality of load transducers, each of the plurality of load transducers including; a plurality of beam portions connected to one another in succession, the plurality of beam portions being arranged in a circumscribing pattern whereby a central one of the plurality of beam portions is at least partially circumscribed by one or more outer ones of the plurality of beam portions; and at least one load cell disposed on one of the plurality of beam portions, the at least one load cell configured to measure at least one force or moment component of a load applied to the load transducer; wherein one or more of the plurality of load transducers is disposed proximate to a respective corner of the at least one plate component; and wherein at least one of the plurality of load transducers comprises a first top surface that is disposed at a first elevation relative to a bottom surface of the load transducer and a second top surface that is disposed at a second elevation relative to the bottom surface of the load transducer, the second elevation being greater than the first elevation; and
wherein a recessed area created by the difference in elevation between the second elevation and the first elevation is used to accommodate one or more electrical components of the at least one load cell of the load transducer. - View Dependent Claims (21)
