摘要： A method and apparatus for measurement of stress in a specimen utilizing a motorized electromagnetic acoustic transducer (EMAT). Stress causes a rotation of the pure-mode polarization directions of SH-waves and a change in the phase of waves polarized along these certain directions. The method utilizes a rotating small-aperture EMAT, connected to a processor, to measure phase and amplitude data as a function of angle. The EMAT is placed on a workpiece at the location where the stress is to be measured. The acoustic birefringence B is determined from the normalized difference of these phases. From these data, an algorithm calculates values of B and &PHgr;. The workpiece is then stressed or its stress state is changed. The values are measured again at the same location. Stress is determined from the change in B and &PHgr;.

摘要： A device for electrically connecting the conductors on a first PC board to the conductors on a second PC board includes a housing having a mounting surface for mounting on the first board, an exposed surface opposite the mounting surface, and a pair of opposed side walls. A plurality of channels open through the exposed surface, each having an interior defined between the interior surfaces of the side walls. A compliant contact element, formed as an integral conductive element, is disposed in each channel. The contact element includes an end portion formed as a termination pad on the mounting surface, a lead portion extending from the first end portion along an adjacent side wall toward the exposed surface and then through the adjacent side wall and the interior surface of that wall into the interior of one of the channels, a supporting portion extending within the interior of the channel, and an electrical contact portion flexibly joined to the supporting portion and extending outwardly from the channel beyond the exposed surface so as to establish electrical contact with one of the conductors on the second board when the second board is located adjacent to the first board. In one embodiment, the electrical contact portion is flexibly joined to the support portion along an arcuate bend so as to form an acute angle therewith. In another embodiment, the electrical contact portion is a finger-shaped element flexibly joined on each side to a cantilevered supporting portion.

摘要： A radio frequency receiver comprising a receiver module, an intermediate frequency (“IF”) module, a synthesizer module and a controller module. The receiver module receives a radio frequency signal and provides a baseband in-phase signal and a baseband quadrature signal, eliminates a sideband of the in-phase and quadrature signals to create a first and a second signal, downconverts the first and second signal to a first and a second IF signal, and selects one of the first or second IF signals. The IF module receives the first or second IF signal, performs analog-to-digital conversion on the first or second IF signal, and demodulates the digitally converted IF signal. The synthesizer module receives a programmable reference signal, downconverts the reference signal to an IF feedback signal, downconverts the reference signal to a baseband feedback signal, provides the IF feedback signal to the IF module, and provides the baseband feedback signal to the receiver module. The controller module samples the digitally converted IF signal and provides the programmable reference signal to the synthesizer module to thereby provide a demodulated output signal.

摘要： An apparatus is disclosed for rotating a structural profile quickly and easily on a single spindle drill line without the use of a crane. The apparatus has two arms which can lay flat or create any angle less than 180 degrees between the two. The apparatus can move horizontally along the drill line and can lift the structural profile vertically for movement and during rotation. This will allow a drill machine operator to rotate large and heavy structural profiles on a drill line and position them with the datum blocks in order to drill the different sides without the need for an overhead crane or other lifting device and
