Abstract: An apparatus is provided for analysis of a leading edge rib of a fixed leading edge section of an aircraft wing. The apparatus may identify geometric or inertial properties of a plurality of stiffeners of the rib, and based thereon perform an analysis to predict a failure rate of the leading edge rib under an external load. From the failure rate, the apparatus may determine a structural integrity of the leading edge rib under the external load. Performing the analysis may include importing a plurality of section cuts into a finite element model of the rib and thereby identifying nodes proximate the section cuts. Under an external load, internal load distributions may be extracted from elements proximate the nodes and elements, and the failure rate of the leading edge rib under the external load may be predicted based on the internal load distributions of the elements.

Abstract: An apparatus is provided for analysis of a leading edge rib of a fixed leading edge section of an aircraft wing. The apparatus may identify geometric or inertial properties of a plurality of stiffeners of the rib in which respective stiffeners are represented by a collection of geometry within a solid model of the rib, and perform an analysis to predict a failure rate of the leading edge rib under an external load. From the failure rate, the apparatus may determine a structural integrity of the leading edge rib under the external load. Identifying the properties may include, extracting a section cut of the geometry that corresponds to and has one or more properties of the respective stiffener, and identifying the properties of the cross-section and thereby the respective stiffener based on a correlation of the cross-section to a generic profile of a plurality of different cross-sections.

Abstract: Improved urine output collection apparatus and monitoring device features are provided. The disposable urine collection apparatus includes a collection reservoir and a diverter for controlling the flow of urine to a first passageway of the diverter in a first position and to a second passageway of the diverter in a second position, wherein the first passageway is fluidly interconnected to the collection reservoir. The disposable urine collection apparatus may include a cartridge having an internal chamber and inlet and outlet members interconnected to the cartridge, wherein the inlet member is selectively, fluidly interconnectable to the second passageway of the diverter, and wherein the outlet member is selectively, fluidly interconnectable to the collection reservoir. The monitoring device is interconnectable with the cartridge and operable to monitor a volume and/or level of urine collected within the cartridge.

Abstract: Fluid/urine monitoring devices and/or systems are provided for monitoring fluid output, including volume and flow rate. One high resolution, low cost electronic urine monitoring device and system collects urine and includes a capacitance sensor. The capacitance of the capacitance sensor may be correlated with fluid content and be used to identify urine volume and flow rate. Another high resolution, low cost flow meter is placed in line with drainage tubing and uses a capacitance sensor to measure fluid output without collecting the fluid. Other low cost urine monitoring devices use pressure based or weight based measurement sensors to measure volume and flow rate.

Abstract: The present disclosure relates to a pre-wetted intermittent catheter apparatus including a collapsible container having a conduit positioned therein as well as a wetting fluid. The conduit has a lubricious coating disposed thereon such that the coating is hydrated upon contact with the wetting fluid in the container, providing a slippery surface for the conduit, which facilitates introduction of the conduit into a user. An introduction member may be incorporated into the distal end of the container and a disposal member may be incorporated into the proximal end, each respectively being positioned in an opening in the container and in communication with the conduit such that fluid flow through the conduit (positioned in the container) is enabled. A bag may be attached to or incorporated into the disposal member to provide a closed system such that the user or assistant is not exposed to potential contaminants.

Abstract: An airfoil which has one or more laminar flow control features to enhance the aerodynamic performance of bluff body vehicles such as buses and truck-tractor trailer rigs. Theses features include a combination of curved and tapered airfoil surfaces, air ejectors or other vacuum producing devices that reduces the air drag over the moving surface. The basic form of structure is a hollow curved and tapered airfoil surface with its base mounted against the rear vehicle wall with hinges such that the airfoil can be folded back against the side of the vehicle.
