Abstract: Monolithic LED chips are disclosed comprising a plurality of active regions on a submount, wherein the submount comprises integral electrically conductive interconnect elements in electrical contact with the active regions and electrically connecting at least some of the active regions in series. The submount also comprises an integral insulator element electrically insulating at least some of the interconnect elements and active regions from other elements of the submount. The active regions are mounted in close proximity to one another with at least some of the active regions having a space between adjacent ones of the active regions that is 10 percent or less of the width of one or more of the active regions. The space is substantially not visible when the LED chip is emitting, such that the LED chips emits light similar to a filament.

Abstract: When predicting required component service in an imaging device such as a magnetic resonance (MR) imaging device (12), component parameters such as coil voltage, phase lock lost (PLL) events, etc. are sampled to monitor system components. Voltage samples are filtered according to their temporal proximity to coil plug-in and unplug events to generate a filtered data set that is analyzed by a processor (46) to determine whether to transmit a fault report. A service recommendation is received based on the transmitted report and includes a root cause diagnosis and service recommendation that is output to a user interface (50).

Abstract: A computationally efficient method, system and programmed medium according to the present invention creates highly accurate maps of celestial bodies, spanning multiple UTM zones given sparse control points on the celestial body surface without requiring the existence or synthesis of a mathematical model of the satellite image sensor. The present invention provides an improved method and system for producing orthorectification coefficients needed to produce highly accurate maps of the surface of celestial bodies that span multiple UTM zones.
