Disclosed is a probe holder for in-line inspection of the surface of bars of high value alloys. To attain full coverage of the inspected surface, the bar is rotated while either the bar or the probe holder is translated. The probe holder of the invention ensures constant probe lift-off by allowing the probe to move freely under its own weight, while constraining the motion to be only in the radial direction of the bar. The lift-off distance is defined by a spacer which is made of soft material to avoid damaging the inspected surface. Although the spacer is soft, its wear due to friction with the rotating bar is minimized by minimizing the pressure between the spacer and the bar. This is achieved by resting most of the mechanism weight on two rollers, with only the much smaller weight of the probe resting on the spacer.

An eddy current probe assembly suitable for inspecting a test object with longitudinal shape, being passed through the assembly in the object's axial direction during an inspection session, the probe assembly comprising multiple probe modules being disposed in a radial plane and with the modules partially overlaying on each other forming an iris structure encircling an inspection zone, wherein a movement in unison of each of the probe modules closer to or further away from the center of the inspection zone makes the inspection zone enlarged or contracted. Spring tension is applied on each of the probe modules so that constant life-off in maintained between the probe modules and the test surface. Array of eddy current elements for each probe module and multiple layers of probe modules can be employed to achieve complete coverage of the test surface. The radial cross-sectional shapes of the test objects can be of round or polygonal.

A medication dispensing system and method where the patient can have his personal console capable of receiving an insert having a tray with an array of medication compartments corresponding to respective times and dates at which the medication is prescribed to be taken. A database in the console can be set with the specified times and dates at which the medication is to be taken. When the console determines the time to dispense medication in one of the compartments has been reached, a visual and/or audible indicator can be triggered. Membranes which are to be hand-removed by the patient cover the respective compartments. A detector provided under the insert can detect across the tray whether or not the membrane corresponding to the selected medication compartment has been removed.

Medication dispensing system and method

Disclosed is a method and an NDT/NDI probe deploying a slit or a flexible joint of probe bending region, preferably between two rows of probe elements to allow free bending between rows of probe elements and along the direction of the rows of elements and to allow two adjacent rows of elements to bend individually along its own natural bending lines perpendicular to the direction of the rows of elements. Also disclosed is the use of protective flexible pads to cover the probe elements and other probe components.
