Abstract: Electronic components are often assembled using robotic equipment, such as pick-and-place machines, that is not optimized for components such as ultra-thin semiconductor bare dice. Selective laser-assisted die transfer is described based on the unique blistering behavior of a multilayer dynamic release layer when irradiated by low energy focused laser pulse(s) in which the blister creates translation of the article being placed. Accurate placement results are provided with negligible lateral and angular displacement.

Abstract: This invention relates to apparatus and methods to detect a target analyte in a test sample by forming a fluorescent complex comprising the target analyte and a probe. The fluorescence decay and/or lifetime changes upon complex formation.

Abstract: Apparatus and methods are provided to monitor hybridization of a probe polynucleotide for detection and analysis of a target polynucleotide in a test sample. A single-stranded probe polynucleotide is attached to an identifiable region on a substrate and allowed to hybridize to a complementary target polynucleotide that may be present in a test sample. A fluorophore noncovalently interacts with the double-stranded polynucleotides that may be formed. The fluorescence decay or lifetime of the fluorophore associated with the double-stranded polynucleotide is different from the fluorescence decay or lifetime of the fluorophore when it is associated with a single-stranded polynucleotide. The detection of double-stranded polynucleotides at a particular region is an indication that the target polynucleotide is present in the test sample.

Abstract: An apparatus for capturing and digitizing a signal derived from an event has a memory for storing a sequence of analog samples from the signal derived from the event in a sampling operation occurring at about a 0.5 gigahertz or higher sampling rate. Circuitry communicating with the memory selectively initiates the read out of the analog samples in the memories. An array of analog to digital converters receives a sequence of analog samples read out from the memory and produces from the analog samples a corresponding vector of digitized sample values. A waveform accumulator integrated with the array of analog to digital converters receives a vector of digitized sample values from a new waveform and combines these with a vector of digitized sample values from at least one prior waveform. An output stage outputs the vector of digitized sample values developed in the waveform accumulator.
