Abstract: A method of calibrating a measurement an inspection system used in the LCD industry is presented. An assembly is created including two substrates coupled by a transducer. Two fixtures also adhere to the substrates and are connected to an interferometer. An inscription is created by marking at least one of the substrates using a reference point on a support table of the measurement and inspection system as a reference. The transducer is then operated to simulate an LCD glass process such as a thermal process or a glass cutting process. Operating the transducer also generates signals that are measured by the interferometer and represent a first distortion measurement. The inscription is then compared to reference mark to determine a second distortion measurement. A comparison of the first distortion measurement and the second distortion measurement are then used to calibrate the measurement and inspection device.

Abstract: A displacement, strain, and/or force sensor assembly (10, 110) has a mounting structure (12) with an anisotropic stiffness to facilitate the measurement of displacements, strains, and/or forces along the X-axis, while minimizing errors due to undesired displacements, strains, and/or forces along the Y- and Z-axes, and rotations about the X-, Y-, and Z-axes. A pedestal (30, 130) configured to respond to axial displacements along the X-axis is centrally disposed on the X-axis of the mounting structure (12), and a displacement or strain sensor (38) is coupled to the pedestal (30) to provide a measure of the displacements, strains, and/or forces. Contact pads (14, 114) are formed on opposite ends of the X-axis of the mounting structure, to enable the displacement and/or strain sensor assembly to be secured to an application structure.

Abstract: A new extensometer is disclosed that avoids prior art problems of drift and other problems from variations in temperature, humidity and other environmental factors. Two primary extensometer body parts each hold at one end specimen contact rods and at their other ends a displacement measuring sensor, preferably a linear variable differential transformer. A thin hinge area connects the two body parts into a single piece monolithic construction so that relative movement between the two body parts is restricted to a single rotational degree of freedom.

Abstract: A position sensor and a method for sensing a position of a moveable member includes at least first and second deflectable members arranged so as to allow the moveable member to pass therebetween and cause the at least first and second moveable members to deflect in proportion to the position of the moveable member relative to the first and second deflectable members. In one example of the present invention, the deflectable members are cantilever-mounted members extending in generally the same direction. The amount of resultant deflection is measured by any suitable means. For example, each deflectable member may have a Wheatstone bridge provided thereon acting as a strain gauge in a known manner, such that the strain detected is proportional to the amount of deflection. In a particular example of the present invention, some of the elements of a first Wheatstone bridge are provided on the first deflectable member and some are provided on the second deflectable member. Likewise, some of the elements of a second Wheatstone bridge are provide on the first deflectable member and some are provided on the second. This desirably provides matched redundancy as well as compensation for spurious lateral movement of the moveable member.
