    摘要： An apparatus and method for use in testing devices under high-g environments is disclosed in which an elastic beam, rigidly fastened at least at one end, carries the device under test; the beam being pre-loaded to a bent position by a force producing member which may be suddenly removed to allow the stored energy of the beam to be released, and to apply a high-g force to the device.

    摘要： An indentation head system for an indentation instrument includes: an indenter tip contacting a sample surface along at least an indentation axis; a reference element supporting the tip; a zero-level sensor generating a signal indicating whether the tip is displaced with respect to the reference element from a neutral relative position; an elastic element between the tip and an actuator with known elongation, the actuator connected to the reference element; and a controller receiving signals from the zero-level sensor to perform servo control of the actuator based on output of the zero-level sensor and the known elongation of the actuator so the zero-level sensor outputs a signal corresponding to a substantially zero displacement of the tip from the neutral relative position, the controller calculating a force applied by the tip to the sample based on an output of the displacement sensor and an elastic coefficient of the elastic element.

    摘要： A handheld quality inspection tool for projection welded components and method for utilizing the same is disclosed. The handheld quality inspection tool includes an elongated hollow tube, a spring support, a spring member, a plunger, and a handle. The elongated hollow tube defines a slot. The spring support is connected to an end portion of the elongated tube. The spring member is disposed within the elongated hollow tube and connected to the spring support. The plunger is disposed in the elongated hollow tube and connected to the spring member opposite the spring support. The handle is connected to the plunger and protrudes from the elongated hollow tube through the slot and is translatable along the slot to move the plunger and compress the spring member. Upon release of the handle, the compressed spring member propels the plunger to apply an impact force to a projection welded component.
