摘要： There is disclosed a meanderline loaded antenna formed by applying a conductive ink or other conductive material to a flexible substrate. The substrate is then shaped by removing regions and folding other regions along perforated or scored lines to fit the antenna within the available space of a wireless device. In lieu of folding regions of a planar substrate to form a three-dimensional structure, the substrate can be vacuum formed over a mandrel after the antenna elements have been formed thereon. The antenna can also be formed by printing on existing enclosure surfaces of a wireless device or on the surfaces of components within the device. Thus the advantages offered by a meanderline antenna where the effective electrical length is greater than the actual physical length are achieved in conjunction with a space-saving physical structure for the antenna.

摘要： A systems for measuring the value of a plurality of parameters includes an optical fiber having a core that conducts coherent light along two orthogonal polarization axes at different velocities, e.g., an elliptical core, a light source for launching linearly polarized coherent light into such fiber to propagate therein as multimodes, a light splitter to divide the light that emerges from the optical fiber into a plurality of light portions, a mode stripper to remove the second order mode of light from the first light portion, a first polarizer to polarize such first light portion after it exits the mode stripper, a first photodetector to convert the polarized first light portion into a first electric signal, second polarizer to polarize a second light portion, a second photodetector to convert the polarized second light portion into a second electric signal, a signal processor to convert the first and second electric signals into a pair of analog voltages, and meters or the like to display such voltages as parameter values, e.g., strain and temperature. The systems may include a third polarizer and third photodetector to process a third light portion for a third parameter measurement, e.g., pressure. Parameter value measurement methods using the new systems are disclosed.

摘要： Range and/or profile of a test surface, particularly a submarine surface, are determined by passing a laser beam through a holographic grating structured to emit a divergent light beam defining a two dimensional array of dots in a predetermined pattern and projecting such beam on the test surface. A receiving device, e.g., video camera, ascertains the positions of the dots in the pattern reflected from the test surface and comparison is made of such positions relative to the positions of the respective dots previously reflected in like manner from a datum surface. The values of the displacements of test surface dots from datum surface dots are used to determine the range or orientation of the test surface relative to the grating or the profile of the test surface.
