  • Patent number: 11016226
    Abstract: A variofocal display device includes an image source and a display. The image source is configured to project image light. The display includes a first optical diffuser and a second optical diffuser. The display is configured to receive the image light. The first diffuser is configured to diffuse the image light at the first optical diffuser when the image light has a first polarization, and to diffuse the image light at the second optical diffuser when the image light is configured has a second polarization different from the first polarization. A method of displaying images using a varifocal display device is also disclosed.
    Type: Grant

  • Publication number: 20120265513
    Abstract: Methods and computing systems for generating a protein stability lookup table and a predictive model. These methods and systems are useful for predicting the thermal stability of a protein sequence and for predicting mutations that may enhance the thermal stability of a protein given its amino acid sequence and/or three dimensional structure. The protein stability lookup table and a predictive model are based on a combination and analysis of related protein sequences and, where available, protein structure data, and relative stability data from mesophilic and thermophilic organisms and experimentally determined stability changes of wild type proteins and their mutants.
