Abstract: An introduced autonomous aerial vehicle can include multiple cameras for capturing images of a surrounding physical environment that are utilized for motion planning by an autonomous navigation system. In some embodiments, the cameras can be integrated into one or more rotor assemblies that house powered rotors to free up space within the body of the aerial vehicle. In an example embodiment, an aerial vehicle includes multiple upward-facing cameras and multiple downward-facing cameras with overlapping fields of view to enable stereoscopic computer vision in a plurality of directions around the aerial vehicle. Similar camera arrangements can also be implemented in fixed-wing aerial vehicles.

Abstract: A method of delivering a variable bit rate (VBR) media stream in near real time includes identifying a selected media asset to be streamed to a media receiver, receiving an available access bandwidth at which the media receiver can receive data, and initiating a session setup for delivery of the selected media asset. The method further includes calculating a delay in decoding a media stream associated with the selected media asset at the media receiver based on the available access bandwidth, and a calculated required minimum transmission rate of a VBR media stream representative of the selected media asset. The method further includes transmitting the selected media asset at the required minimum transmission rate of the VBR media stream and providing the calculated delay to the media receiver such that the media receiver begins decoding the media stream in accordance with the calculated delay.

Abstract: An insulating unit has a pair of glass sheets about an edge assembly to provide a compartment between the sheets. The edge assembly has a U-shaped spacer made of metal, metal coated plastic, gas and moisture impervious polymer, or gas and moisture impervious film coated polymer. The outer legs of the spacer and the glass provide a long diffusion path to limit the diffusion of argon gas out of the compartment. The edge assembly has materials selected and sized to provide edge assembly having an RES-value of at least 75. A spacer for use in insulating units includes a plastic core having a gas impervious film e.g. a metal film or a halogenated polymer film. Also taught herein are techniques for making the unit and spacer.

Abstract: A gas cap cover device for an automotive vehicle gas cap includes a shell configured to be disposed over a portion of a gas cap. A connector is supported on the shell and is configured to engage the gas cap and cause the gas cap to rotate when the cover device is rotated. A message-bearing element is supported on the cover device and is configured to display a message formulated to influence a vehicle operator to take some action. In addition, a method for reducing emissions from automotive vehicles includes replacing old leaking gas caps with new gas caps that each include a message advertising a product or service or encouraging participation in activities related to automotive emissions reduction. The message may be included on the message-bearing element of the gas cap cover device.

Abstract: A buffered optical fiber ribbon cable includes at least one optical fiber ribbon cable, which has parallel optical fibers encased in a ribbon matrix sheath, and a ribbon buffering layer surrounding the optical fiber ribbon cable. The ribbon matrix sheath is at least partially molecularly bonded to outer coatings of the optical fibers and surrounds the parallel optical fibers, thereby holding the optical fibers immediately adjacent one another. The material of the ribbon buffering layer is preferably UV curable resin or thermoplastic material. Also, the ribbon buffering layer material may further contain imbedded reinforcement fibers for strengthening the ribbon buffering layer. The ribbon buffering layer is made of a material that allows the buffered optical fiber ribbon cable to be installed in environments independent of any additional protective cable covering.

Abstract: In a live multicast in a LAN environment, audio and video streams are transmitted from a source station to a plurality of receiving stations. A technique is disclosed for synchronizing the audio decoder clock at each receiving station with the source station. A technique is also disclosed for synchronizing the audio and video data streams received at each receiving station.

Abstract: An apparatus and method for use in a network including source clients and viewer clients connected to one or more shared transmission media. A video server is connected to one of the transmission media and is operative to control the broadcast and storage of multiple live or previously-stored video streams. The control may be provided via remote procedure call (RPC) commands transmitted between the server and the clients. In one embodiment, a video presentation system is provided in which a video stream from a source client is continuously broadcast to a number of viewer clients. One or more of the viewer clients may be authorized by the source client to broadcast an audio and/or video stream to the other clients receiving the source video stream. In another embodiment, a multicast directory is provided to each of a plurality of viewer clients by transmitting directory information in a packet corresponding to a predetermined multicast address.

Abstract: Material to be treated is transported through a treatment zone bounded by a foraminous member that separates the treatment zone from an immediately adjacent zone of high density vapor. The vapor is flowed through the foraminous member and directly into the material at a continuous rate and with a major portion of the vapor flowed from the vapor zone being entrained by the material in the treatment zone. The continuous moderate flow of vapor into the bed of material produces rapid vapor transfer and with excellent distribution of the vapor within the material being treated.

Abstract: A new and distinct cultivar of Spathiphyllum characterized particularly as to novelty by leaf morphology that has a surface textured in a corrugated manner with margins having an undulating appearance, the resulting plant having desirable characteristics sought for commercial production.
