Abstract: A test fixture for securing a test article is disclosed. The test fixture includes a frame, an upper grip, at least one heat shield, a cooling assembly, and insulation. The frame defines an upper portion and a lower portion. The lower portion of the frame is releasably mounted to a vibration device. The upper grip is connected to the upper portion of the frame and the lower grip is connected to the lower portion of the frame. The heat shield is positioned to insulate at least one of the upper grip and the lower grip. The upper grip is configured to secure an upper portion of the test article along an upper interface. The lower grip is configured to secure a lower portion of the test article along a lower interface. The cooling assembly transports a cooling medium across at least one of the upper interface and the lower interface.

Abstract: Methods, compositions, and medical kits are useful for treating and preventing multiple sclerosis using 1-(4-(((6-amino-5-(4-phenoxyphenyl)pyrimidin-4-yl)amino)methyl)piperidin-1-yl)prop-2-en-1-one, or a pharmaceutically acceptable salt thereof, according to preferred dosing regimens.

Abstract: Techniques are described for the exchange of control signals between a controlled unmanned aircraft (i.e. drone) and a ground control station and for the transmission of communication signals, such as video, from the drone to the ground control station so that the signals are more difficult to intercept or jam. The video signal transmitted from the drone can be an analog RF signal employing one or more of video “scrambling”, RF signal inversion, hopping, usage of a wide frequency range and other techniques. To secure the control signals between the drone and the ground control station, techniques can include hopping, encryption and use of a wide frequency range.

Abstract: The present disclosure concerns a warning device comprising a warning body having a longitudinal axis and comprising a light-emitting assembly; and a collapsible stand configurable in a compacted configuration and in a warning configuration in which the light-emitting assembly is at least partially visible. The collapsible stand comprises a handle sleeve mounted to and slidable along the warning body and legs pivotably mounted to the handle sleeve, the legs being juxtaposed against the warning body when the collapsible stand is in the compacted configuration to cover the warning body and the legs extending outwardly and downwardly when the collapsible stand is in the warning configuration, the collapsible stand being configurable between the compacted configuration and the warning configuration by sliding the handle sleeve along the warning body. The disclosure also concerns a warning assembly comprising such a warning device and a method of emitting a warning light signal.

Abstract: Described herein is an apparatus and method to convey an object through the air in a controlled and repeatable manner. The apparatus may comprise an object attached to at least one resilient member, the resilient member or members constraining object movement in a substantially vertical y-axis direction. The apparatus may also comprise at least one support member coupled to the at least one resilient member, and the support member or members constrain object movement in a substantially horizontal x-axis direction. In use, the resilient member is energised, movement initiated, and object movement then occurs in an x-axis and a y-axis direction, the movement path substantially governed by the resilient member(s) and the support member(s). The apparatus and method may allow the object to experience a variety of movement sensations, one being the feeling of flight or gliding.

Abstract: A composition including an isolated cloaked gene editor. A composition for treating a lysogenic virus, including a vector encoding isolated nucleic acid encoding two or more cloaked gene editors chosen from cloaked gene editors that target viral DNA, cloaked gene editors that target viral RNA, and combinations thereof. A composition for treating a lytic virus, including a vector encoding isolated nucleic acid encoding at least one cloaked gene editor that targets viral DNA and a cloaked viral RNA targeting composition. A composition for treating both lysogenic and lytic viruses, including a vector encoding isolated nucleic acid encoding two or more cloaked gene editors that target viral RNA. A composition for treating lytic viruses. A method of preventing antibody neutralizing effects with gene editors in humans. Methods of treating a lysogenic virus or a lytic virus, by administering the above compositions to an individual having a virus and inactivating the virus.

Abstract: A pumped or gravity flow rotating drum screen removes unwanted solids from a flowing fluid. The drum screen may comprise: a housing having a fluid inlet end, a solid discharge end and an area between the two ends, the fluid inlet permitting a flow of influent containing unwanted solids into a hollow portion of a drum screen positioned lengthwise in the area between the two ends of the housing, the screen comprising a filter medium that retains at least a portion of the unwanted solids within the hollow portion of the drum screen and which produces a liquid effluent that is discharged from an outer surface of the drum screen, the retained solids being removable via the solid discharge end; a drive assembly configured to rotate the drum screen about an axis running the length of the drum screen; and one or more stabilization pad assemblies in contact with one or more rings circumscribing the outer surface of the drum screen at one or more locations.
