Abstract: Vertical resolution and/or vertical accuracy of terrain elevation data near an aircraft runway is adjusted by obtaining local terrain data, yielding a first elevation value for a query location. A processor receptive of the first elevation value computes plane equations based on a predetermined standard model adapted to geometrically conform to the aircraft runway, yielding a second elevation value for the query location. The processor selectively uses the first and second elevation values to generate an adjusted elevation value that is supplied to a terrain avoidance and warning system.

Abstract: Phosphor-converted LED side reflectors disclosed herein comprise pigments that are photochemically stable under illumination by light from the pcLED. The pigments absorb light in at least a portion of the spectrum of light emitted by the first phosphor converted LED. The side reflector may also comprise light scattering particles or air voids. The pigments, light scattering particles, or air voids may be homogeneously distributed in the reflector. Alternatively the side reflector may be layered, with the pigments, light scattering particles, or air voids inhomogeneously distributed in the reflector. The side reflector can include phosphor particles.

In at least one embodiment, the drill rod handler (30) comprises a boom (32) having jaws (38) for releasably grasping a drill rod (14) in at least two spaced apart positions along the length of the drill rod, and a boom positioning means for positioning the boom so that the jaws may grasp a drill rod (14) from a rod storage (18) on the drilling rig or from another rod storage at a different location (16). In another embodiment, a drill rod handler comprising a boom having jaws for releasably grasping a drill rod in at least two spaced apart positions along the length of the drill rod, a boom tilt mechanism for raising or lowering an end of the boom and a drill rod when the drill rod is grasped by the jaws; and an interconnect for connection to the end of the boom for stabilising the end of the boom with respect to the a mast (20) of the drilling rig (10) when the boom (32) is in a rod presentation position.

Abstract: Methods and systems for color error correction for a segmented LED array are disclosed. A method includes calculating a target luminance for LED segments in a segmented LED array based on an initial luminance pattern, determining a luminance ratio based on the target luminance, the luminance ratio defined as a ratio of a primary luminance value of the primary LED segment to a secondary luminance value of the at least one adjacent LED segment, and comparing the luminance ratio to a predefined threshold ratio. If the luminance ratio is greater than or equal to the predefined ratio, then the secondary luminance value of the at least one adjacent LED segment is maintained. If the luminance ratio is less than the predefined ratio, then the secondary luminance value of the at least one adjacent LED segment is increased.

Abstract: Described herein is a method and system for dual stretching of wafers to create isolated segmented chip scale packages. A wafer having an array of light-emitting diodes (LEDs) is scribed into LED segments, where each LED segment includes a predetermined number of LEDs. The scribed wafer is placed on a stretchable substrate or tape. The tape is stretched and a layer of optically material is placed in the separation gaps. The stretched wafer is scribed on a LED level. The tape is stretched and another layer of optically opaque material is placed in the separation gaps. The same or different optically opaque material can be used for the layers. The two layers of optically opaque material are formed to provide electrical connectivity between the LEDs in each LED segment. In an implementation, each segment or LED is individually addressable.
