Abstract: A weight management mat for passively and automatically monitoring weight for one or more individuals in a household. The weight management mat generally includes a housing having an upper mat and a lower mat between which is sealed a pair of perpendicular sensor arrays. Each sensor array includes fiber optic cables laid out in a grid pattern. One or more microbend inducers act to induce detectable microbends in the fiber optic cables when an individual steps on the upper mat. The change in light intensity caused by these microbends is recorded by photodetectors and processed by a microcontroller. The present invention may be utilized to identify each unique individual stepping on the present invention by the pressure map of their feet. Thus, recorded weight measurements may be tracked to aid in weight management.

Abstract: The deformation sensor does not require a supplementary sensor to check functionality. This deformation sensor includes an optical transmission medium, multiple transmission elements, which couple the light of various wavelengths into the transmission medium, and multiple reception elements, which selectively couple the transmitted light out of the transmission medium according to wavelength. An evaluation unit detects deviations between the output signals of the reception elements and signals a malfunction of the sensor if the deviations exceed a preset measure.

Abstract: An optical fiber (7) exhibits varying transmission characteristics in different strain states and can have an S-shaped microbend. For producing such a fiber it is heated locally in a small region, as viewed in the longitudinal direction of the fiber, and then the portions of the fiber (1) located at the two sides of the heated region are displaced in relation to each other in a transverse direction in relation to the longitudinal direction of the fiber. It can be performed in a conventional fusion-splicing apparatus for optical fibers. Alternatively, a laser can be used as a heating source, what is particularly suitable for processing optical fibers having longitudinal cavities in order to infer to it similar transmission characteristics. The optical fibers produced by this method are suited for use as sensors, e.g. strain gauges.
