  • Patent number: 10641690
    Abstract: A material testing apparatus includes an actuator to apply a force to a load head according to electronic control signals. The load head supplies a load to a material specimen in a first dimension. A plurality of load line displacement (LLD) reference points extend radially outward from the load head; and a plurality of LLD measuring devices correspond to the plurality of LLD reference points. Each LLD measuring device is positioned to detect a position of a corresponding LLD reference point along the first dimension and is configured to transmit position signals to a controller programmed to perform a performance test on the material specimen using feedback control based on a combination of the position signals, including an average of the position signals.

  • Patent number: 10520614
    Abstract: A method for calibrating a nuclear gauge of the having a source includes providing a nuclear gauge comprising a radiation source, the radiation source being coupled with a computing system with a machine readable program stored thereon containing a calibration routine. An operator places the gauge on one or more specified blocks to adjust the source within each block to one or more specified positions to initiate a count. The method includes determining that the source is at each position before each count begins, adjusting the counting times before each count begins by the program on the nuclear gauge based on each position of the source to obtain calibration information, obtaining counts at each position, storing the counts within the computing system of the nuclear gauge, and calculating for each position calibration coefficients.
