| 20100231907 | Method and Apparatus for Biosensor Spectral Shift Detection - Performing high-resolution determination of the relative shift of the spectral properties of a biosensor. The shift in the resonance peak of the biosensor is indicative of the amount of material bound to the surface of the biosensor. A preferred biosensor is a Guided Mode Resonant Filter Biosensor (GMRFB). In one aspect of the invention, curve fitting is used to determine the relative location of the spectrum of the unexposed biosensor with respect to those spectra that are altered (e.g., shifted) by the presence of materials bound to the surface of the biosensor. In an alternative embodiment, the cross correlation function is used to detect spectral peak offsets between a reference spectrum and a spectrum measured from an exposed biosensor. In yet another alternative, maximal likelihood estimation techniques are used to determine the spectral shift or offs. | 09-16-2010 |

| 20080224908 | Mixer/DAC Chip and Method - An electronic chip has a data input for receiving an input digital data signal with a data frequency, a plurality of switches, and a logic circuit operatively coupled with both the plurality of switches and the data input. The logic circuit controls the switches to be in one of a DAC mode or a mixer mode. The DAC mode causes the switches to convert the input digital data signal into a DAC analog signal having about the data frequency. The mixer mode, however, causes the switches to convert the input digital data signal into a mixed analog signal having a mixer frequency that is higher than the data frequency. | 09-18-2008 |
