  • Patent number: 10439733
    Abstract: An optical circuit breaker includes a main optical transmission path including an optical coupler, a delay line and a protection device, and a parallel protection path configured to receive a tapped portion of a signal provided to the main optical transmission path and generate a reference signal based on the tapped portion. The protection device may be configured to be triggered to prevent an overpower condition from passing through the optical circuit breaker responsive to the reference signal exceeding a user selectable threshold. The delay line may be configured to have a longer delay than a time it takes for the protection device to be triggered via the parallel protection path.

  • Publication number: 20180335408
    Abstract: A system and method for performing UV LED-based absorption detection for capillary liquid chromatography for detecting and quantifying compounds in a liquid, wherein a simplified system eliminates the need for a beam splitter and a reference cell by using a stable UV source, and power requirements are reduced, resulting in a portable and substantially smaller system with relatively low detection limits.

  • Publication number: 20180250610
    Abstract: A system and method for performing liquid chromatography for separating molecules in a liquid solution, wherein a single column includes two of more separation segments, each separation segment having a separate detector immediately after each separation segment, wherein a mobile phase is inserted into a first separation segment and moves through the column until passing through a last separation segment, and then using the data from the detectors to perform compound identification.

  • Patent number: 9884351
    Abstract: A process for treating a substrate comprised of sorptive material is provided herein. The sorptive material may be an absorbent synthetic material such as polyester. The material is designed to be used for cleaning surfaces in an ultraclean environment. The process first comprises unwinding a roll of sorptive material as a substrate into a cleaning system. The cleaning system utilizes several sections. These include a pre-washing section, an acoustic energy washing section, and a drying section. Preferably, the process of moving the substrate through the cleaning system is continuous. The acoustic energy washing section employs one or more acoustic energy generators. In one aspect, the process also includes cutting the substrate into sections to form wipers after moving the substrate through the drying section. Thereafter, the wipers are placed into a bag and the bag is sealed.

  • Patent number: 9678046
    Abstract: A system and method for thermal gradient gas chromatography wherein a front or injection end of a column is heated to a higher temperature than a back or detector end to thereby create a thermal gradient having a profile that is substantially monotonically non-increasing and has a positive second derivative, and then providing a heat source to raise the thermal gradient and cause it to remain stationary or to travel through the column while maintaining a desired profile.

  • Patent number: 9640374
    Abstract: A new algorithm is taught for identifying compounds from spectroscopic or mass spectra data, wherein the improved order of operations of the present invention are defined as 1) background noise removal, 2) deconvolution by smoothing peaks, finding peaks and grouping peaks into unknown compounds, 3) preparing correlation values for combinations of unknown compound and target compound pairs, 4) sorting the combinations of unknown compound and target compound pairs by their correlation values, 5) removing complete ions from the mass spectra data using a peak, a retention time, and a retention window, and 6) matching unknown compounds to target compounds such that no target compound appears twice.

  • Publication number: 20150203907
    Abstract: Provided herein is a capture library for target enrichment of sequences of interest from a genome DNA sample. The capture library comprises a plurality of capture oligos tiling a plurality of capture regions evenly-spaced along a genome. Each two adjacent capture regions of the plurality capture regions are separated by a spacing of about 6 to about 14 kilobases in length. The plurality of capture regions has a size of about 150 base pairs in length. Further, each capture oligo of the plurality of capture oligos comprises average 70 nucleotides in length. The capture libraries are suitable for enriching about 150 base pairs region approximately every 10 kilobases in a genome DNA. This capture library can be used to measure replication timing and copy number variation in human pediatric acute lymphocytic leukemia samples, and is also broadly applicable to any CNV application.
