Abstract: A fiber-optic sensor matt detects movements of a person on the matt that cause microbending of a fiber-optic cable that is arranged into a symmetric pair of radial ring groups within the matt. There are no cross-over points or overlapping of the fiber-optic cable within the symmetric pair of radial ring groups that could cause fiber wear and noisy readings. Microbending of the fiber-optic cable pressed into a mesh modulates the light intensity received, which is analyzed to extract both respiration and heart BallistoCardioGram (BCG) waveforms by convolution with Daubechies dB5 wavelet and scaling functions. The reconstructed level-4 detail waveform is output as the extracted BCG, while the reconstructed level-6 approximation waveform is output as the extracted respiration waveform. Respiration and heart rates and variations can be generated from the extracted waveforms. An integrated Fast Wavelet Transform (FWT) using dB5 wavelet thus generates both respiration rate and heart rate.

Abstract: A garment to generate a three-dimensional (3D) visual effect may include a base fabric layer and an outer fabric layer. In one embodiment, the outer fabric layer is meshed with a consistent thickness that makes up only a small fraction of the overall thickness of the 3D fabric. In an exemplary embodiment, the base fabric layer may have a first feature while the outer fabric layer has a second feature. The first feature and the second feature may be slightly misaligned and a 3D visual effect may be generated when the first feature and second feature start to move and separate from each other. The misalignment of the first and second features is actually configured to create and enhance the 3D visual effect of the garment.
