  • Publication number: 20240151975
    Abstract: A display subsystem for a virtual image generation system for use by an end user comprises a planar waveguide apparatus, an optical fiber, at least one light source configured for emitting light from a distal end of the optical fiber, and a collimation element mounted to a distal end of the optical fiber for collimating light from the optical fiber. The virtual image generation system further comprises a mechanical drive assembly to which the optical fiber is mounted to the drive assembly. The mechanical drive assembly is configured for displacing the distal end of the optical fiber, along with the collimation element, in accordance with a scan pattern. The virtual image generation system further comprises an optical waveguide input apparatus configured for directing the collimated light from the collimation element down the planar waveguide apparatus, such that the planar waveguide apparatus displays image frames to the end user.

  • Patent number: 10480018
    Abstract: Disclosed herein are three geneses of proteins herein established to exhibit a fructose to allulose epimerase activity that are useful for production of allulose from fructose at high temperatures and at low pH in the range of 4.5 to 6.0. Two of the three geneses descend phylogenetically from a common ancestral protein defined herein, and these geneses are distinguished from each other by different parental descendant proteins also defined herein. The proteins with high levels of sequence identity to the parental nodes defining from these two geneses generally exhibit higher levels of specific fructose to glucose epimerase activity than prior known fructose to allulose epimerases and exhibit such activity at low pH. A third genus is not defined by phylogenetic origin except by not descending from the same ancestor as the first two geneses but generally exhibit similar levels of fructose to allulose epimerase activities as prior art epimerases described to be useful for fructose to allulose conversion.

  • Patent number: 10443060
    Abstract: The present disclosure provides nucleic acids and vectors for use with methanotrophic bacteria. Related host cells and methods for using such nucleic acids and vectors for expressing polypeptides or other genetic manipulation of methanotrophic bacteria are also provided. In one aspect, the present disclosure is directed to a non-naturally occurring nucleic acid molecule, comprising (1) a promoter that is functional in a methanotrophic bacterium, and (2) a native or altered methanol dehydrogenase (MDH) ribosomal binding sequence, provided that when the promoter is an MDH gene promoter, the nucleic acid comprises an altered MDH ribosomal binding sequence.
