  • Patent number: 4843291
    Abstract: A digital-to-synchro converter is provided where a binary input code specifies a desired shaft angle and where an resolver type position transducer is employed with additional circuitry to generate a shaft position error signal indicative of the angular difference between the desired shaft angle and the actual shaft angle. The additional circuitry corrects for known and calculated errors in the shaft position detection process and equipment.

  • Patent number: 4756195
    Abstract: Apparatus for measuring the modulus of elasticity of a sample specimen of a given thickness and area includes means for mounting one surface of the specimen on a rigid reference plane and an opposing surface of the specimen is then mounted on a rotatable surface. A torque arm coupled to the rotatable surface applies a predetermined torque which effectively causes this surface to rotate thereby twisting the specimen through a given angle. The angle is measured by means coupled to the rotatable surface, and based on the measured angle, one can calculate the modulus of elasticity in regard to the measured angle and in regard to the applied torque. The apparatus and methods essentially measure the modulus of elasticity through angular displacement of the specimen.
