US Patent:

6964205, Nov 15, 2005

Filed:

Dec 30, 2003

Appl. No.:

10/748718

Inventors:

Thomas Papakostas - Boston MA, US
Christopher George - Lynn MA, US
Charles Malacaria - Medfield MA, US
Mark Lowe - Sharon MA, US

Assignee:

Tekscan Incorporated - South Boston MA

International Classification:

G01D007/00

US Classification:

73862046

Abstract:

A sensor for measuring a parameter applied to a surface is provided. The sensor includes at least one substrate layer, a plurality of individual sensor elements operatively arranged with respect to the substrate layer, and a conductive trace disposed on the substrate layer. The conductive trace is electrically coupled to an individual sensor element and wraps around at least a portion of the sensor element in a spiral-like manner. Further, by employing slits or cut-outs of material between sensor elements, a sensor element may move independent of an adjacent sensor element, thereby allowing the sensor to conform to an irregularly shaped surface or otherwise when subject to relatively large deflections. The sensor may be employed to detect force distribution of a seating surface, such as a seat cushion of a wheelchair.

Abstract:

Embodiments disclosed herein relate to a thin, light, and portable system for measuring one or more parameters of a contact patch between a tire and a surface. The system may be configured with an array of sensors capable of being removable fixed to the surface. The array of sensors may measure the one or more parameters of the contact patch between the tire and the surface. Moreover, the system may include a scanner configured to interpret the measurements from the array of sensors as data and store the data.
