Assignee:

Syngenta Participations AG - Basel

International Classification:

G01N 3353

US Classification:

435 71

Abstract:

The present invention provides plant ENR-A, CBL, UROD, PBGD, and CPPO genes. Also disclosed are the recombinant production of ENR-A, CBL, UROD, PBGD, and CPPO enzymes in heterologous hosts, screening chemicals for herbicidal activity using these recombinantly produced enzymes, and the use of thereby identified herbicidal chemicals to suppress the growth of undesired vegetation. Furthermore, the present invention provides methods for the development of herbicide tolerance in plants, plant tissues, plant seeds, and plant cells using ENR-A, CBL, UROD, PBGD, and CPPO genes of the invention.

Abstract:

Methods, systems, and computer readable media for minimal-latency tracking and display for matching real and virtual worlds in head-worn displays are disclosed. According to one aspect, a method for minimal-latency tracking and display for matching real and virtual worlds in head-worn displays includes calculating a desired image, calculating an error image as the difference between the desired image and an image currently being perceived by a user, identifying as an error portion a portion of the error image having the largest error, updating a portion of a projected image that corresponds to the error portion, and recalculating the image currently being perceived by a user based on the updated projected image.
