A light conversion device and high-intensity, solid-state light source utilize wavelength conversion elements with a thermal conductivity greater than 1 watt per meter per degree Kelvin (W/m-K). Exemplary materials that have high thermal conductivity include monocrystalline solids, polycrystalline solids, substantially densified ceramic solids, amorphous solids or composite solids. The light conversion device and high-intensity, solid-state light source have at least one heat sink that is in direct thermal contact with the wavelength conversion element. The heat sink quickly dissipates heat generated within the wavelength conversion element in order to prevent the wavelength conversion element from overheating and undergoing thermal quenching of the wavelength conversion and light emission.

A general purpose integrated circuit (IC) tester includes a set of channels, one for each input or output pin of an IC device under test (DUT). Each channel is programmed by a host computer to either supply a test signal to a DUT I/O pin or sample a DUT output signal appearing at the I/O pin and produce sample data representing its magnitude or logic state. The tester also includes an amorphous logic circuit (ALC) having a set of input and output terminals and a programmable logic circuit interconnecting the input and output terminals. Some of the ALC input and output terminals receive the sample data produced by each channel and other ALC terminals send control signals directly to each channel. Other ALC terminals transmit data to the host computer. When it programs the channels to perform a test, the host computer also programs the ALC to control various operations of the channels during the test, to perform a real-time analysis of the test data produced by the channels, and to communicate results of the analysis to the host.
