Patent number: 7278327Abstract: Simultaneous pressure and position information is accurately measured in a sensor realized by utilizing first and second sensor elements that each exhibit a decreasing width over the length of the sensor element and that are arranged overlapping each other and in a substantially complementary orientation to one another with respect to the width so that the point of narrowest width of the first sensor element overlaps the point of the widest width of the second sensor element. Pressure applied to the sensor causes each sensor element to generate an electrical signal that is proportional to both the applied pressure and the surface area at the location of the applied pressure. As a result of the complementary orientation and overlapping for these sensor elements, the first and second sensor elements generate an asymmetric pair of signals that uniquely define the applied pressure by position and magnitude.Type: GrantFiled: July 26, 2005Date of Patent: October 9, 2007Assignee: New Jersey Institute of TechnologyInventors: Timothy N. Chang, Biao Cheng

Patent number: 7278324Abstract: A sensor has a plurality of carbon nanotube (CNT)-based conductors operatively positioned on a substrate. The conductors are arranged side-by-side, such as in a substantially parallel relationship to one another. At least one pair of spaced-apart electrodes is coupled to opposing ends of the conductors. A portion of each of the conductors spanning between each pair of electrodes comprises a plurality of carbon nanotubes arranged end-to-end and substantially aligned along an axis. Because a direct correlation exists between the resistance of a carbon nanotube and its strain, changes experienced by the portion of the structure to which the sensor is coupled induce a corresponding change in the electrical properties of the conductors, thereby enabling detection of crack growth in the structure.Type: GrantFiled: June 15, 2005Date of Patent: October 9, 2007Assignee: United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Jan M.

Patent number: 7275452Abstract: A beam load cell transducer is positioned between a stationary member and moveable member. The stationary member, as well as the moveable member are surrounded by a collar, which collar has an inner surface means to limit the movement of the moveable member of the transducer. By limiting the movement and restraining further movement after a predetermined excessive force is applied, one stops the beam and therefore prevents the beam from fracturing or rupturing. In the unlikely event that the beam does fracture or rupture, then the sleeve acts to hold the entire unit together, thereby maintaining integrity to the transducer.Type: GrantFiled: March 25, 2003Date of Patent: October 2, 2007Assignee: Kulite Semiconductor Products, Inc.Inventors: Anthony D. Kurtz, Adam Kane, Richard Martin
