Abstract: Methods and devices are presented for transforming a layout of a densely packed grid of micro-LED light emitters to a layout of a square rectilinear pixel grid to achieve compatibility with hardware and software used in imaging and display technologies. In particular, a pattern of regular hexagonal emitter cells for fabrication on a III-nitride substrate can be transformed to a square pixel array of irregular hexagonal trichrome pixels that are readily addressable. Separation between adjacent trichrome pixels, and between their constituent emitters, can be established for overlay tolerance, while maintaining a cell packing density of about 70% and a pixel pitch of about 4.0 ?m. Wavelength and quantum efficiency properties are shown to depend on optical current density, which can be determined by the emitter area specified in the grid layout.

Abstract: An ADS-B traffic filter to remove ADS-B positional messages or tracks with unstable ADS-B data or anomalies. The anomaly in ADS-B data can be caused by own ship ADS-B data processing and by errors in ADS-B OUT messages, such as positional outliers, ADS-B OUT parameters gaps, frozen data, walking track when stopped and other issues encoded within ADS-B OUT messages. The ADS-B traffic filter of this disclosure may remove erroneous ADS-B targets from computation input delivered to a traffic collision warning systems in locations where high horizontal position accuracy is desirable such as ground operations. The filter may validate and compare positions decoded from received ADS-B OUT messages, and short duration data history of targets, to independent signal components from ADS-B broadcast (e.g., position and ground speed data), as well as compare the reported position with a reasonability bound provided by local runway or airport geometry data.
