Abstract: The present disclosure relates to methodologies, systems and apparatus for cooling pump heads and providing balanced cooling and heat transfer between multiple pump heads. Multi-pump systems that are used to pump fluids that vary greatly in density with minor changes in temperature, such as the mobile phase of a C02-based chromatography system, require highly stable temperature conditions. In order to achieve a substantially equal average heat transfer between multiple pump heads and a coolant fluid, coolant fluid may be flowed through coolant passageways within the pump heads in a recursive and/or parallel coolant flow patterns. Such recursive and/or parallel coolant fluid flow patterns provide increased stability in temperature, compressibility, and density of the fluids passing through a multi-pump system.

Abstract: A patient support apparatus for supporting a patient in a prone position during a surgical procedure is provided, including an open patient support frame suspended above a floor and a base for supporting and suspending a the frame during a surgical procedure, the base including a pair of spaced vertically translatable subassemblies reversibly attachable to the frame by a pair of fail-safe rotatable connector attachment mechanisms to prevent inadvertent uncoupling of a first and second outer end of the frame from the base structure.

Abstract: Novel solutions, which can include devices, systems, methods, than can measure earthquakes and other displacement events. Some solutions feature the integration of real-time, high-rate global navigation satellite system (“GNSS”) displacement information with acceleration and/or velocity data within a single device to create very high-rate displacement records. The mating of these two instruments allows the creation of a new, very high-rate displacement measurement device that has the full-scale displacement characteristics of GNSS and high-precision dynamic motions of seismic technologies. Such a device can be used for earthquake early warning studies and other mission critical applications, such as volcano monitoring, building, bridge and dam monitoring systems.

Abstract: Method and apparatus for enhancing the accuracy of the elevation coordinate in a survey that uses GPS survey measurements to determine location coordinates for a plurality of survey locations. An optimal locally-best-fitting plane is combined with a geoid model that represents a local region of the Earth, in order to decrease the inaccuracy associated with an elevation coordinate in the survey to a fraction of a decimeter.

Abstract: A blade-mounted total pressure (BMTP) probe for a rotor blade comprises a base segment and an inlet segment. The base segment includes an interface surface having a planar configuration that is complementary to an aerodynamic surface of the rotor blade for detachably mounting the BMTP probe in combination with the rotor blade, an aerodynamically-streamlined body member contiguous with the interface surface that includes a leading edge and first and second flow surfaces, and a fluid communication aperture extending through the aerodynamically-streamlined body member and the interface surface. The inlet segment comprises an inlet defined by a lower wall contiguous with the aerodynamically-streamlined member, opposed sidewalls contiguous with the lower wall, and an upper wall contiguous with the opposed sidewalls.

Abstract: The present invention is a sample deposition device for depositing a plurality of samples onto a test media substrate, and a method of depositing a plurality of samples onto a planar test media substrate, such as a stationary phase chromatographic medium, agar or tissue. In broadest terms, the device of the present invention comprises (a) a substantially planar support portion defining a plane; and (b) an array of substantially planar absorbent portions releasably connected to the support portion, the absorbent portions aligned substantially parallel to said plane. The absorbent portions may be impregnated with a test sample before use. The present invention also includes a method of depositing one or more samples onto a test media substrate.

In broadest terms, the device of the present invention comprises (a) a substantially planar support portion defining a plane; and (b) an array of substantially planar absorbent portions permanently connected to the support portion, the absorbent portions aligned substantially parallel to said plane. The absorbent portions may be impregnated with a test sample before use. The present invention also includes a method of depositing one or more samples onto a test media substrate.

Abstract: A freeze-resistant downspout system includes a metal downspout having an interior portion within a building and a contiguous exterior portion outside the building. The exterior portion is shielded from the weather by a thermally insulated shroud so that heat conducted along the downspout from within the building is sufficient to keep the exterior portion from freezing.

Abstract: This invention provides a primary standard and/or secondary standards for assay for glycated proteins in samples such as blood. The primary standard is composed of a polymer or copolymer of an amino acid, such as lysine, serine or those listed on table 37 (pages 100-110 of the second edition of Organic Chemistry by Robert Morris and Robert Nielson-Boyd) glycated with a known amount of glucose, preferably .sup.14 C glucose or .sup.3 H glucose, and free of unbound glucose. The preferred secondary standards are composed of glycated native protein per se, or a mixture of a glycated native protein and native protein that has been standardized against a primary standard to give the actual glycated protein value. These primary standards and secondary standards may be packaged and sold as a kit that contains a primary standard and/or a secondary standard and the reagents needed to perform the glycated protein assay.
