Abstract: The emergency egress apparatus includes a protuberance mated to a first portion of the door barricade and a keeper mated to a second portion of the door barricade. A retainer is selectively disposed between one of two positions. A first position defines the placement of the retainer that establishes an interference fit between the protuberance and the keeper. A second position defines the placement of the retainer such that it is not in contact with the protuberance or the keeper. The first position secures the first portion of the door barricaded with respect to the second portion of the door barricade, and the second position decouples the first portion of the door barricade with respect to the second portion of the door barricade.

Abstract: Endovascular variable aortic control catheters (EVACC) are provided that are adapted to augment upstream blood pressure and regulate downstream blood flow for patients in shock. The EVACC devices provide improved treatment for truncal wounds, which may be used for example on a battlefield, thereby increasing survivability of injured soldiers. The devices are a catheter-based system having a proximal hand piece for controlled deployment of the device through a delivery sheath. A collapsible, wire framework supports an expandable and collapsible occlusion barrier. The wire basket and occlusion barrier expand to fit within the lumen of the aorta. Various movable elements are used to adjust an adjustable passageway to regulate controlled anterograde blood flow.

Abstract: A repeater for maintaining wireless line of sight communications. The repeater is autonomously repositional in both absolute location and azimuthal orientation. The repeater has at least two vibratory motors, or other vibration sources, which provide oscillations to depending legs against a support surface. By selectively operating one or more of the vibration sources together or independently, the repeater may be moved as helpful to maintain line of sight communication with another repeater or other operational hardware. A command signal from a remote base station controls the locomotion of the repeater to provide both a change in absolute position relative to the surroundings and a rotational change in azimuthal orientation as necessary to maintain communication under dynamic conditions.

Abstract: A morphing airfoil includes a dynamic flexible skin system that is capable of carrying high level aerodynamic (or fluid) pressure loads over a structural surface. The structural surface can morph and bend in response to control inputs to change a lift force without separate movable control surfaces. A plurality of standoff mounts is attached to an inner surface of anisotropic skin. The standoff mounts include through apertures for receiving a flexible stringer. The anisotropic skin is attached to underlying structure through the flexible stringers. The flexible stringers interface with actuated position control ribs and passive compliant support ribs. A control system causes the underlying support structure to move to a desired location which in turn causes the skin to bend and/or flex without exceeding a stress threshold and thus vary the lift and drag distributions along a span of the airfoil without separate control surfaces.

Second messages are received at the first node from the second node, which are indicative of: (i) a rate of arrival at the second node of the first messages, and (ii) successful and unsuccessful delivery of the first messages. A transmission rate limit and a window size are maintained according to the received second messages. Transmission of additional messages from the first node to the second node is limited according to the maintained transmission rate limit and window size.

Abstract: A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury.

Abstract: A jammer which eliminates the need for a bobtail in a forward deployment. The jammer has an outwardly extending boom with a table at the distal end of the boom. The table can mount upwardly extending cradles suitable for temporarily holding cargo, such as a munition, during transport and positioning on the underside of an aircraft wing. The table also holds an upstanding pintle hook. The pintle hook provides for attachment of the jammer to a trailer for towing. Using the jammer for both towing of a trailer and positioning of cargo using the boom eliminates the need for a bobtail, conserving both cargo space and payload weight during deployment.
