Abstract: Single-stranded oligonucleotide probes, systems, kits and methods for chromosome enumeration, gene copy enumeration, or tissue diagnostics. The probes are particularly suited for detecting gene amplification, deletion, or rearrangement in tissue samples in a single, dual, or multiplexed assay. The probes exhibit improved performance compared to industry leading dual-stranded probes; particularly in terms of the rate of hybridization.

Abstract: A commutator/manifold assembly controls a flow of hydraulic fluid in a hydraulic fluid system. The assembly includes a commutator having an offset design including an inner portion eccentrically encompassed within an outer portion, and offset commutator porting to control the hydraulic flow. A manifold includes manifold ports having a straight configuration by which walls defining the manifold ports run substantially along a longitudinal axis through an entirety of the manifold. The commutator is configured to rotate to sequentially align the commutator porting with differing portions of the manifold ports to control the flow. The commutator porting includes inner ports and outer ports that are isolated from each other by a commutator seal. A commutator ring has a guiding surface that guides rotation of the commutator. The rotation of the commutator provides a timed flow through the manifold ports straight through the manifold and without any directional flow restriction.

Abstract: An inflatable component for a protective headgear according to various embodiments can include an inner surface facing an outer shell of the protective headgear. One or more inflatable structures may be provided between the inner surface and an outer surface of the inflatable component. A structure of the inflatable structure is designed having a pre-determined cross-sectional profile. The pre-determined cross-sectional profile of the inflatable structure is configured based on a head injury criteria. In various embodiments, the system and method can include an energy absorption component. In other embodiments, the system and method can include a reactive component.

Abstract: A brake apparatus for a mowing machine that includes a brake gear operatively rotatable with a rotatable member and a lock assembly for meshing with the brake gear to restrict rotation of the brake gear. A guide rail assembly is fixable relative to a support for supporting the rotatable member for rotation. The guide rail assembly guides a lock assembly movable between an unlocked arrangement and a locked arrangement. An actuator plate and the guide rail assembly jointly engage the lock assembly to effect meshing and unmeshing of at least one engagement member of the lock assembly, such as a roller or a jaw member, with the brake gear. The actuator plate is selectively rotatable about an axis of rotation of the brake gear relative to the guide rail assembly, where rotation of the actuator plate effects movement of the lock assembly between the unlocked and locked arrangements.

Abstract: An enclosure assembly configured to receive a plurality of fiber membranes configured to filter fluid may include an elongated tubular member including an elongated wall extending between first and second ends, and a removable hatch coupled to opposing side edges of the elongated wall, thereby forming a hollow enclosure having an interior. The interior of the elongated tubular member may be configured to receive a plurality of fiber membranes configured to filter fluid.

Abstract: A single header filter cartridge for removing contaminates from water using a plurality of hollow fiber membrane filters, and methods of using the same, is provided. The single header filter cartridge contains a plurality of hollow fiber membrane filters secured at the top of the cartridge in a header to form a fiber bundle, the filter ends designed to be freely suspended in the water, a central aeration tube positioned at the cartridge bottom, and a vent tube positioned near the cartridge top that creates a void space within the fiber bundle.

Abstract: An apparatus including a downhole tool for conveyance in a wellbore extending into a subterranean formation and method of use thereof. The downhole tool may include a turbo-alternator disposed in a passageway for drilling mud, and a controller to: track operating points of the turbo-alternator, determine from the operating points a flow rate of the drilling mud, and control a component of the downhole tool based on the flow rate.
