Publication number: 20200319226Abstract: The present invention relates to profiler systems and methods for observing and sensing aspects of a body of water at a plurality of depths. A water profiler is disclosed comprising, generally, a vessel body connected to an external mooring mechanism via an attachment mechanism, a drive mechanism for maneuvering the vessel body longitudinally about the mooring mechanism; an articulating mechanism; and a sensor array capable of measuring a parameter for study wherein the vessel body is capable of articulating about the mooring mechanism. In alternate embodiments, the articulation allows the vessel body to be placed in relation with the three dimensional current such that at least one sensor is positioned into the current so as to sample or measure undisturbed water. In alternate embodiments, hydrofoils or wings are mounted to the vessel body that can be manipulated to harness the current force and maneuver the vessel body.Type: ApplicationFiled: April 6, 2020Publication date: October 8, 2020Inventors: John M.

Patent number: 9552545Abstract: A filter assembly is provided for collecting samples in a fluid environment, the assembly utilizing a laminar convective flow to cause the flow of a preservative/fixative and a filtrate through a filter. A substantially concave dead space around the filter is flushed free of the preservative and the differential in density of the preservative and filtrate causes the more dense fluid to collect in the reservoir and preserve the collected specimen.Type: GrantFiled: March 28, 2013Date of Patent: January 24, 2017Assignee: MCLANE RESEARCH LABORATORIES, INC.Inventors: Craig D. Taylor, Kenneth W. Doherty, Susumu Honjo

Patent number: 6803237Abstract: A sequential processing reactor vessel and method is disclosed for accelerated extraction and fractionation of chemical analytes from complex solid sample materials. The device and method provide for sequential extraction of elemental constituents from solid materials by sequentially contacting target samples within a single reaction vessel using a series of different reagents at temperatures as high as 150° C. and pressures up to 150 psi to accelerate reactions. The aggressive chemical treatments provided by the disclosed device and method enable the complete digestion of solid samples in liquid analyte samples that can be directly analyzed by conventional spectrometry or other suitable methods. The disclosed device and method provide for efficient sample processing and accelerated reactions to significantly reduce processing times and costs for elemental analysis of solids while improving accuracy, precision and reliability of results compared to conventional devices and methods.Type: GrantFiled: January 25, 2001Date of Patent: October 12, 2004Assignee: Woods Hole Oceanographic InstitutionInventors: Steven J.

Patent number: 5876380Abstract: A portable syringe dispenser system capable of holding one or more syringes containing different types of fluid medicine therein. Filled syringes, holding enough fluid medicine for multiple injections, are placed into syringe holders in the dispenser and inserted into a sterile mixing chamber. The dosage of each type of fluid medicine in each syringe is independently adjusted employing a dose adjusting indicator system. An activation system allows all doses of the fluid medicine to be simultaneously injected through a replaceable sterile needle. The sterile needle can remain on the dispenser system. The sterile needle maintains its sterility by sealing it with a sealing cap. This allows the needle to be reused. In addition, a dosage/time recording unit can be attached to the portable syringe dispensing system to accurately record at least the time, date and amount of fluid medicine injected. A plurality of these recordings can be made.Type: GrantFiled: June 18, 1996Date of Patent: March 2, 1999Inventors: Steven J. Manganini, Kenneth W. Doherty
