Abstract: A power management system includes a relay connected to an electrical load, a power management module configured to receive electrical power from each of a battery and a utility source, and in communication with the relay, and a controller in communication with the battery and the power management module. The controller monitors a battery load on the battery and communicates to the power management module to selectively disconnect the relay connected to the electrical load based on the battery load.

Abstract: A fibrous vehicle underbody shield and method for manufacturing the same is provided. A binderless core of non-woven fibrous material defines first and second surfaces of the fibrous vehicle underbody shield. The second surface of the fibrous vehicle underbody is opposite the first surface such that the first and second surfaces are separated by a final product thickness. The first and second surfaces include at least one molded contour that gives the first and second surfaces a non-planar shape. The non-woven fibrous material of the binderless core includes a plurality of fibers that are mechanically entangled with each other and have a coating that withstands a heat exposure of 200 degrees Celsius. The fibrous vehicle underbody shield includes a latex impregnation. The latex impregnation is disposed on at least one of the first and second surfaces and penetrates the non-woven fibrous material of the binderless core an impregnation distance.

Abstract: A method for reducing training requirements for clinical trial staff including receiving clinical trial information for a clinical trial, wherein the clinical trial information includes one or more clinical trial tasks, one or more training units associated with at least one of the tasks, and clinical trial protocol requirements; providing a list of the clinical trial tasks to a user for selection, wherein the user is a member of the clinical trial staff; generating a training program for the user, comprising a plurality of assigned training units, wherein each of the assigned training units are associated with the selected clinical trial tasks; providing the assigned training units from the training program to the user for completion; documenting completion of the assigned training units; and documenting confirmation that the user is qualified for the clinical trial after completion of the assigned training units, wherein confirmation is provided by a principal investigator.

Abstract: An acoustic barrier assembly for a vehicle and a method of manufacturing the same is disclosed. A decoupler layer surrounds a pass-through opening in a wall of the vehicle to defining a decoupler aperture that is open to the pass-through opening. A barrier layer abuts the decoupler layer and defines a barrier aperture that is also open to the pass-through opening. An acoustic seal is integrally formed in the barrier layer. The acoustic seal defines an exposed region of the barrier layer that is not bounded by the decoupler layer. The exposed region of the barrier layer directly contacts the wall around the pass-through opening and seals around a penetrating member that extends through the pass-through opening. The acoustic seal thus reduces flanking noise traveling through a gap between the penetrating member and the pass-through opening.

Abstract: The disclosed acoustic insulator mat includes a first absorber layer made of a non-woven fibrous material. The non-woven fibrous material comprises a mesh of intertwined fibers that defines a plurality of cavities. The first absorber layer has a first side and a second side. Peripheral cavities are arranged along the second side of the first absorber layer between peripheral fibers. A coating is disposed on the second side of the first absorber layer. The coating is adhered to the peripheral fibers and thus includes a plurality of discontinuities at the peripheral cavities such that the coating provides a partial barrier to noise at the second side of the first absorber layer. The acoustic insulator mat may optionally include a second absorber layer that is retained on the first absorber layer by the coating. A method of manufacturing the acoustic insulator mat is also disclosed.
