Abstract: Systems and methods for dynamically generating application programming interfaces and managing functions associated with a data object type. In an aspect, the system accesses an object definition for a type of data object. The system generates an application programming interface associated with the type of data object, based at least partly on the object definition. The system determines a change to the object definition for the type of data object and updates the application programming interface based at least partly on the change to the object definition.

Abstract: An RGB (red-green-blue) laser light source for projection displays that combines a plurality of beams into a smaller cross-sectional area, optionally co-axially combining beams of different colors, and angularly and spatially homogenizing the result for a collimated output with better etendue. Some embodiments use slotted mirror(s)s and/or wavelength-selective filter-reflectors for combining laser beams from two laser arrays, hexagonal light guide(s) and/or diffuser(s) to homogenize the beam, rotational and/or translational movements of diffuser(s) to reduce speckle contrast, optional turning mirrors to shorten lengths of the structure for use in moving-head stage-light systems. In some embodiments, laser-diode packages are integrated with collimating lenses, reducing the size of the package and the system as a whole.

Abstract: A system for troubleshooting network problems is disclosed. A model can use demographic information, network usage information, and network membership information to determine an importance of a problem. The importance of the problem for the user who reported the problem, a number of other users affected by the problem, and the importance of the problem to the other users can be used to determine a priority for resolving the problem. Before and after a work order is executed to resolve the problem, network metrics can be gathered, including aggregate network metrics, and automatically presented in various user interfaces. The analysis of the metrics can be used to update a database of which work orders are assigned in response to which problems.
