A fiber-locating structure for aligning an optical fiber includes opposed first and second faces. A first wall, defining a funnel, extends from the first face toward the second face; while a second wall, defining a tunnel, extends from the second face toward the first face. The first and second walls are disposed such that the funnel and the tunnel meet to form a continuous passageway between the first face and the second face.

An actuator for controlling a pitch angle and a yaw angle of a mirror in a fiber-optic switch includes a piezoelectric strip having a first and second arm. The first arm extends from a substrate in a first direction. The second arm, which is for attachment to the mirror, extends from the first arm in a second direction different from the first direction. A pitch-electrode, in electrical communication with the first arm, controls pitch angle by causing deflection of the first arm. A yaw-electrode, in electrical communication with the second arm, controls the yaw angle by deflecting the second arm.

Eddy current detection probes and related methods are disclosed. In some embodiments, the eddy current detection probes are hybrid probes, including a solid state sensor and a detection loop. In some embodiments, the eddy current detection probes include a drive coil and a detection loop, with the detection loop having a sensitive axis that is not parallel to principal axis of the drive coil. In some such embodiments, the sensitive axis of the detection loop is perpendicular to the principal axis of the drive coil.

Devices and methods for detecting defects in reinforced concrete using eddy current detection technology are disclosed. In one aspect, a method for detecting defects in reinforced concrete may include the steps of: providing a probe with a plurality of eddy current sensors disposed along a circumferential direction of the probe; inducing an eddy current in a reinforcing structure of the reinforced concrete with at least one of the plurality of eddy current sensors; and detecting a circumferential and longitudinal location of a defect in the reinforcing structure of the reinforced concrete with at least one of the plurality of eddy current sensors.

An optical switching element for use in an optical cross-bar array, includes a magnetically responsive curtain that switches between an extended state and a deflected state in response to an applied switching-field. The switching element includes a curtain that moves in response to a magnetic field. The curtain has a fixed edge attached to a substrate and a free edge opposite the fixed edge. A first magnetic-field source magnetically coupled to the curtain generates a first magnetic field that urges the curtain into an extended position in which the curtain intercepts the optical beam. A second magnetic-field source, also magnetically coupled to the curtain, generates a second magnetic field that urges the curtain into a deflected position in which the curtain avoids intercepting the optical beam.
