Abstract: Provided herein is a method for detecting the presence of clade variants in the COVID-19 virus in a human sample and/or an environmental sample. Samples are processed to obtain total RNA. The RNA is used as a template in a combined reverse transcription and amplification reaction to obtain fluorescent COVID-19 virus amplicons. These amplicons are hybridized on a microarray with nucleic acid probes having sequences that discriminate among the various clade variants. The microarray is imaged to detect the clade variant. Also provided is a method of distinguishing each clade variant from others by generating an intensity distribution profile from the image, which is unique to each of the clade variants.

Abstract: A motion damper for structures includes a housing coupled to a structure such that the housing moves in correspondence with the structure. The housing includes a wall with a vent, and has an air chamber therein in fluid communication with the vent. A piston is sealed within the housing for one-dimensional motion therein. A rigid plate is disposed within the housing's air chamber. The plate is disposed between the piston and the vent, and is spaced apart from and fixedly coupled to the piston such that the plate moves in correspondence with the one-dimensional motion of the piston. At least one spring is mounted in the housing and is coupled to the plate for applying a force thereto that is in opposition to the one-dimensional motion of the piston.

Abstract: A motion damping system includes a tank compartmentalized to have a first compartment having a first opening, a second compartment having a second opening, and a third compartment disposed between the first and second compartments. The third compartment is in fluid communication with the first and second openings. A first piston is movably sealed within the first compartment and is in fluid communication with its first opening. A second piston is movably sealed within the second compartment and is in fluid communication with its second opening. A liquid fills the third compartment, a portion of the first compartment up to the first piston, and a portion of the second compartment up to the second piston. A coupling fixedly attached to the first and second pistons moves in correspondence with the first and second pistons. Motion damper(s) coupled to the coupling resist movements of the first and second pistons.

Abstract: A mode splitter (300) for a balance bar (150) of a Coriolis flow meter (100) is disclosed. The mode splitter (300) comprises a mass portion (302), and a first coupling portion (304a) coupled to the mass portion (302). The first coupling portion (304a) has a first stiffness in a drive direction (Y) and a second stiffness direction in an orthogonal direction (Z), and the orthogonal direction (Z) is orthogonal to both the drive direction (Y) and a longitudinal direction of the balance bar (150). The second stiffness is different than the first stiffness.

Abstract: A dynamics management system for a structure includes a line whose first end is coupled to a first location within a structure. A tension resistance device is coupled to a second location within the structure. The tension resistance device generates a first force when a tension force is applied thereto and generates a lesser second force when the tension force is not applied thereto. The second end of the line is coupled to the tension resistance device wherein the first force is applied to the line when it is in tension and the second force is applied to the line when it is not in tension. The line traverses at least one Z-shaped path within and in a plane of the structure. The line is coupled to the structure at each inflection point of the Z-shaped path(s) for supporting movement of the line there along.

Abstract: The invention relates to a direct burial ground lug. The lug is preferably constructed of a phosphor bronze material. The block may have two through holes to install two conductors, rods, cables, and the like. Stainless steel threaded screws are used to hold the rod and ground conductor in a stable condition. The threaded screws insert into threaded holes positioned perpendicular to the through holes. The direct burial ground lug allows the ground rod and ground conductor to be connected for a continuous grounding system.
