Abstract: A gimbal sleeve for connecting to a camera gimbal may float between a floor surface and a ceiling surface of an aerial vehicle chassis such that the gimbal sleeve has freedom of motion in yaw, pitch, and roll directions relative to the vehicle chassis. The gimbal sleeve may comprise a pair of connection points to the lower dampers on a floor surface of the vehicle chassis. The gimbal sleeve may furthermore comprise a ball joint coupled to a back surface of the vehicle chassis. The connection points include spring forces that enable the gimbal sleeve to return to an equilibrium position in response to external vibrations and reduce the magnitude of vibrations transferred from the aerial vehicle to the gimbal and camera systems.

Abstract: A safety device allows selective opening or closing of a drain opening of a tank, to render such action more difficult for a child. The device has a body, a plug, a means for restricting axial movement of the plug in a conduit that runs through the body, and, optionally, a tether. The conduit is adapted for engagement in the drain opening. The plug is frictionally engaged in the conduit. The means for restricting axial movement has complementary elements disposed on the plug and on the body, such that, in a first rotational position, the plug is axially retained relative to the conduit and, in a second rotational position, the plug is not restricted from axial movement out of the conduit. The tether attaches to the plug and the body to keep the plug proximate to the body.

Abstract: A gimbal sleeve for connecting to a camera gimbal may float between a floor surface and a ceiling surface of an aerial vehicle chassis such that the gimbal sleeve has freedom of motion in yaw, pitch, and roll directions relative to the vehicle chassis. The gimbal sleeve may comprise a pair of connection points to the lower dampers on a floor surface of the vehicle chassis and a pair of connection points to upper dampers on a ceiling surface of the vehicle chassis. The connection points include spring forces that enable the gimbal sleeve to return to an equilibrium position in response to external vibrations and reduce the magnitude of vibrations transferred from the aerial vehicle to the gimbal and camera systems.

Abstract: A spout that dispenses water from a water dispenser has a disinfection portion that provides two passes of the water therethrough. The disinfection portion has two flow tubes, the second arranged inside the first, so that an annular cross-section flow path is defined by an inside wall of first tube and an outside wall of the second tube. A second flow path having a circular cross-section is defined by an inside wall of the second tube. The water flow is transferred between the flow at a second end of the disinfection portion by a second end portion. At a first end portion, located at a first end of the disinfection portion, a first end portion body provides connections to the disinfection section for both an inlet and an outlet. The order of flow through the disinfection portion flow paths may depend upon the orientation of the spout.

Abstract: A device (10) for dispensing cold water has a modular disinfection system (100) that maintains the water near a dispensing spout (40) in a disinfected condition. The modular disinfection system has an ultraviolet (UV) radiation generator, a fluid entrance (104), a fluid exit (106) and a UV-transparent tube (108) that connects the fluid entrance to the fluid exit and maintains the next water to be dispensed. A housing (70) receives the modular disinfection system with the fluid entrance is vertically above the fluid exit. A control means (80) operates both the UV radiation generator and a valve means that allows water to be dispensed through the dispensing spout.

Abstract: An insulated building block having a three-section configuration wherein a first cementitious segment containing the internal core hole of the block is interlocked with second cementitious segment by a serpentine configured insulated insert. The insulation insert is operatively arranged to have multiple lips that mate with various indented ledges on each of the other segments in a location proximate to the surface of the cementitious segments. The insulating insert is also configured with wedge holes that accommodate wedges which press into the installation to maintain continuity of the block. The insulation insert has groves that in combination with the other segments form a trough in fluid communication with weep holes which extend through the insulation insert which allows for condensation and seepage of water to drain from the block.
