Abstract: A measurement arrangement has a rotation axis around a first end of an extended member having a first joint thereat, and a second joint at the opposing end. An equipment for recording measured points is connected to the second joint. The joints are connected through a cord or wire. The equipment is arranged to rotate through a pre-determined angle when the member is turned around its rotation axis. An angle sensor records the rotation of the equipment relative to the member. The cord or wire rotates the equipment through an angle corresponding to the angle that the member has rotated around its rotation axis. The equipment and the member rotate in opposite directions, and the angles of rotation are recorded when the equipment detects the limiting surface of the object on both sides of the diameter to be measured. A processor calculates the diameter based on the angles of rotation.

Abstract: A bottom tool/bending die for use in sheet metal forming. The bottom tool includes a pair of movable dies that provide substantially continuous support of a work piece as it is being deformed. Each die includes an upper surface configured to contact the work piece and having an inner and an outer edge. As the die moves in the tool, the inner edge of the upper surface is closer to a center of rotation of the die than the outer edge. In some embodiments, the upper surfaces of the dies are shaped so that a fixed separation is maintained between the inner edges of the dies as they rotate. In at least one embodiment, sector gears are used to control the motion of the dies.

Abstract: A caliper for measuring tree diameters of trees. A slide having a permanent magnet is movable along a graduated rule, the caliper including a pair of legs, one leg attached to one end of the rule, and another leg attached to the slide. An electronic unit measures the position of the slide along the rule and stores measurement values and other desired data. A wire extends within a longitudinal internal cavity in the rule and co-acts with a piezo crystal adjacent an end of the caliper. The wire is connected to a pulse generator that generates short electric pulses of predetermined duration. The caliper also includes a detector that co-acts with the piezo crystal and with the pulse generator pulses to detect a geometric change in the wire that is sensed by the piezo crystal, which emits an electrical pulse in response to that geometric change.

Abstract: Two magnetically sensitive field plates are provided in a caliper to determine the distance between a movable leg and a stationary leg. The field plates are located on the movable leg adjacent grooves in a portion of the caliper which is magnetic and along which the movable leg is moved. Each plate magnetically senses each groove and produces an electrical signal in response thereto. The field plates are arranged relative to each other so that the signals produced therefrom are out of phase with each other, the phase difference between the two signals indicating the direction of travel of the movable leg and the number of signals indicating the magnitude of the movement of the movable leg. Depending on the direction of travel, the number of signals are added or subtracted to determine the distance between the legs.
