Polarization Analyzer Based Detection Schemes for Pol-Mux Self-Coherent Single Sideband Optical Transmission
Researchers at the University of Arizona have developed an orthogonal frequency division multiplexing (OFDM) optical communication system for access networks that can work in a direct receiver mode and in a coherent receiver mode. Compared to currently available OFDM products, the novel system has fewer components and is simpler to set up. Background:...

Spectral-Tagging Technique for Improving Resolution of Dynamic Echo-Planar Imaging
This invention is a spectral-tagging method that allows for 3X faster speed of acquisition with improved resolution of the targeted physiology. The invention improves upon echo-planar imaging by band-pass filtering different signals to reconstruct a specific spectral peak, resulting in high quality images without aliasing artifacts from multi-band echo-planar...

Real-Time Signal Processing and Fitting Method
This non-invasive electronic device is worn on the body while monitoring vagus nerve activity in order to observe and obtain data about breathing patterns. The software filters and conditions the raw data by using a Fast Fourier Transform (FFT). The software proceeds to apply an error-reducing algorithm which finds the best fit for the conditioned data...

Energy and Memory Efficient Analog to Digital Image Processing Method for use in Data Intensive Systems
This invention starts from the mixed signal data collection and integrates the sampling scheme with memory and digitization. This integrated interface model will reduce the data amount at the very beginning of data acquisition. Thus, data received at the CPU, as well as power consumption in the CPU, will be greatly reduced. In this implementation, there...
