Abstract: A vertical takeoff and landing aircraft is described in which rotors can be disposed underneath the booms. This will allow for zero downward force resulting from thrust on the aircraft and therefore greater energy efficiency. Retractable doors can shield the rotors when not in use, decreasing drag during forward flight.

Abstract: A collar for having in cross-section a generally triangular filler section and a generally rectangular outer section over the filler section. The collar may be part of a tube assembly where the collar serves to couple a fitting to tube. A method of installing the collar includes pressing the collar over the outer surface of the tubing until the strain on the collar in the hoop direction is at a predetermined level.

Abstract: Identifying participants for collaboration in a threat exchange community can include receiving security data from a plurality of participants at a threat exchange server within the threat exchange community; and in response to receiving from a first participant from the plurality of participants security data associated with a security occurrence, identifying at the threat exchange server the first participant and a second participant from the plurality of participants for collaboration based on characteristics of the first participant and the second participant.

Abstract: Sharing information can include identifying, utilizing a threat exchange server, a security occurrence associated with a participant within a threat exchange community. Sharing information can also include determining what participant-related information to share with the threat exchange server in response to the identified security occurrence, and receiving, at the threat exchange server, information associated with the determined participant-related information via communication links within the threat exchange community.

Abstract: Eccentrically loaded structural members and methods of forming the same. The structural members have their compressive loading axes offset from their load central longitudinal axes.

Abstract: Threat exchange information protection can include receiving security information from a number of participants of a threat exchange community, wherein a portion of the received security information is encoded with pseudonyms by each of the number of participants, analyzing the security information collectively from the number of participants, wherein the portion of the received security information remains encoded, and sending analysis results to each of the number of participants, wherein the analysis results include information relating to the portion.

Abstract: A composite tube assembly and a method of making the same are provided. The composite tube assembly includes a composite tube and a fitting penetrating the composite tube. The fitting includes a reduced diameter section surrounded by a reduced diameter tube portion of the tube. A bolstering structure surrounds this reduced diameter tube portion. The method includes inserting the fitting into the composite tube, heating the tube portion surrounding the fitting to soften the same, radially compressing the tube portion onto the fitting reduced diameter section, and providing a bolstering structure surrounding the compressed tube portion.

Abstract: A baluster driver tool for rotating a baluster to threadably secure it to a support. The driver tool includes a housing having a connector at one end for connecting it to a drill and a baluster-engaging member at the opposite end for receiving the baluster. The baluster-engaging member includes a cavity that is complementary sized and shaped to receive an end of the baluster. When the drill is activated, the housing rotates about its longitudinal axis causing the baluster to rotate in unison with the housing and securing a threaded end of the baluster into the support. In a second embodiment, a smooth tapered end of a baluster is received within a threaded tapered cavity in the housing. The threads secure the smooth tapered end of the baluster within the cavity so that rotation of the housing causes the baluster to rotate in unison therewith and securing the threaded end of the baluster to the support.

Abstract: An apparatus and method to synchronize devices in a network to a sub-millisecond timing accuracy. In a first embodiment, the transmission of data is synchronized between a first source device and destination devices communicatively coupled to a network. In a second embodiment, data is deterministically transmitted between a first source device and destination devices communicatively coupled to a network. In a third embodiment, a deterministic network synchronizes the transmission of data between a first source device and destination devices coupled to a network.
