Abstract: A buoyant aerial vehicle system includes a balloon, a ballonet configured to selectively receive and discharge a gas to adjust an altitude of the balloon, and an energy regeneration assembly. The energy regeneration assembly includes a turbine and an electric motor. The turbine is coupled to an outlet of the ballonet, such that gas released by the bayonet activates the turbine. The electric motor is operably coupled to the turbine and is configured to convert mechanical energy received from the turbine into electrical energy and convey the electrical energy to a battery.

Abstract: A motor housing includes a core and a shell having an annular body. The annular body is configured to secure a stator of a motor therein. The annular body includes first and second ends defining first and second openings, respectively. The annular body defines a slot extending along a length of the annular body. The slot is coterminous with the first opening. The core is configured to be in registration with the shell. The core is configured to rotatably support a rotating assembly of the motor including an output shaft. The core includes a base portion, an annular ring, and a guide arm interconnecting the base portion and the annular ring. The core is in registration with the shell when the guide arm is received in the slot of the annular body of the shell to form an interlocking structure.

Abstract: A valve assembly for use with an unmanned aerial vehicle is provided and includes an inlet tube, a shuttle, a base plate, a screw assembly, and a spacer block. The shuttle is partially disposed within the inlet tube and is configured to be placed in a first position where the shuttle abuts the inlet tube and a second position where the outer surface is disposed in spaced relation to the inlet tube. The base plate extends between a first end portion that defines a cavity therein and a second end portion. The screw assembly is disposed within the cavity of the base plate and is coupled to a portion of the shuttle. The spacer block is interposed between the second end portion of the inlet tube and the first end portion of the base plate and is configured to maintain the inlet tube and the base plate in spaced relation.

Abstract: An implant delivery system, comprising: an implantable device comprising a plurality of supports extending between a proximal end and a distal end, the supports being moveable between a collapsed configuration and an expanded configuration, a proximal guide tube at the proximal end of the supports extending toward the distal end, and a distal guide tube at the distal end of the supports extending toward the proximal end, wherein the proximal and distal guide tubes are telescoping and become further engaged as the supports move from the collapsed to the expanded configuration.

Abstract: A system and method for retrieving an implantable device includes a delivery catheter, a recapture section, and a sheath. The delivery catheter has a proximal end and a distal end. The recapture section is axially extendable from the distal end of the delivery catheter. The sheath has a proximal end and a distal end and a lumen sized to receive the delivery catheter. A portion of the lumen of the sheath is actuatable from an enlarged inside diameter to a reduced inside diameter to apply an inwardly directed force to the recapture section. The delivery catheter can be actuated with respect to the sheath to extend or retract the recapture section with respect to the delivery catheter.

Abstract: The present application provides various examples of bracket for mounting a shelf to a flat vertical surface such as a wall. Examples and configurations disclosed herein provide brackets that have a high ratio of weight-supporting capacity to visibility relative to previous wall-mountable shelf-support apparatuses. One or more elongate members may extend through one or more apertures in a metal base. The proximal end(s) of the one or more elongate members may be welded to the back of the metal base around a cross-sectional perimeter of a cross-sectional shape that is shared by the proximal ends of the elongate members and the back ends of the apertures.

Abstract: A method of managing leakage of liquid inside a battery system comprises: containing leaking liquid in a non-liquid sensitive region of the battery system so as to protect internal electrical components of the battery system from coming in contact with the leaking liquid; and in direct response to the leakage, expunging the leaking liquid from the battery system. A drain device includes: a body with a port therethrough, the body configured to be positioned in a wall of a container; means for opening the port in response to a first liquid contacting the drain device on an inside of the container; and means for resisting ingress into the container by a second liquid that contacts the drain device on an outside of the container.

Abstract: A smart label includes an antenna and an integrated sensor, and in response to receiving an initiating interrogation signal transmits a response signal that includes a first component that identifies the smart label and second component that provides data generated at the sensor in response to an environmental parameter. The response signal allows the data indicating the status of the environmental parameter, such as temperature or moisture, at the location of the specific smart label to be transmitted along with a time stamp. A method of activating a sensor on the smart label is also provided.

Abstract: A user annotates a shared document with text, sound, images, video, an e-mail message, graphics, screen snapshots, web site snapshots to share with others. The document and its annotations are stored in a digital object repository to which other users have access. Within the closed collaboration system, only users who are authenticated may upload digital objects, annotate digital objects and view objects and their annotations. The user sends a message to other users to invite them to view the object and its annotations and to add their own annotations. An annotated object generates an alert for all of the invited users. A remote authentication gateway authenticates users and has a repository for user metadata. Digital object repositories are separate from the authentication gateway, thus providing for disintermediation of the user metadata from the digital object data. The collaboration system may be hosted by a third party on a server computer available over the Internet that displays a web site.
