Abstract: In some implementations, a server may receive, from a user device, one or more credentials associated with a user. Accordingly, the server may transmit, to the user device, instructions for generating a user interface including a plurality of visual components based on authenticating the user with the one or more credentials. The server may detect, during a first interval, a lack of interaction with the user interface. Accordingly, the server may remove one of the plurality of visual components from the user interface based on the lack of interaction. Additionally, the server may detect, during a second interval, one or more interactions with the user interface and may update a similarity score associated with the user based on properties associated with the one or more interactions. Accordingly, the server may restore the visual component to the user interface based on the updated similarity score satisfying a similarity threshold.

Abstract: A bracket for locating a vertical reinforcement bar within a block wall having a central area to enable a reinforcement bar placed vertically through a void of a block wall to pass through the bracket; and a locator for locating the central area in a predetermined position within the void of a block wall; wherein one or more guides extend into the central area to guide one or more reinforcement bars through a central aperture, the central aperture defined by the one or more guides.

Abstract: An electrical connector comprises a plug connector and a socket connector connectable to respective electrical conduits, wherein the plug connector and at least partly prevent or minimize rotational and/or longitudinal movement of the electrical conduits relative to the connectors. The socket connector may comprise a rotatable retainer comprising one or more flange members and the plug connector may comprise one or more complementary flange members, so that rotation of the retainer facilitates engagement between the respective flange members of the socket connector and the plug connector. Power sources are also provided which comprise the hereinbefore described rotatable retainer and flange elements.

Abstract: An air swirler arrangement comprises a coaxial arrangement of an inner and an outer air swirler passage. Each air swirler passage comprises a radial flow swirler. Air swirler arrangement comprises a coaxial arrangement of first, second and third members. Second member has radially extending upstream portion spaced axially from first member and a convergent portion. Third member has a radially extending upstream portion spaced axially from the upstream portion of second member and a radially inner surface having convergent and divergent downstream portions and a radially outer surface having a divergent downstream portion. First, second and third members the vanes of the radial flow swirlers is a monolithic structure. Plurality of circumferentially spaced passages are provided within the third member and each passage has an inlet in the surface and an outlet arranged to direct fluid onto the divergent portion of the surface or the surface of the third member.

Abstract: A retractable needle is provided for a syringe comprising a barrel and a plunger that comprises a portion capable of engaging the retractable needle for retraction. The retractable needle comprises a cannula, a needle body having a plunger-engaging member, at least one aperture and an elongate portion which houses the cannula, the cannula comprising an end which is in fluid communication with the at least one aperture, wherein the at least one aperture is located between the plunger-engaging member and the elongate portion. The positioning of the at least one aperture distal to the plunger-engaging member maximizes the efficiency of fluid delivery.

Abstract: A modular wiring system comprising a functional unit and a wiring unit. There is also a system for coupling the functional unit to the wiring unit in a rotational manner. This system can be formed from at least one locking prong comprised of electrically conductive material. When the functional unit is coupled to the wiring unit, the locking prong is both electrically and physically coupled to the functional unit at a first end and to the wiring unit at a second end. Alternatively, or in addition, the system for coupling the functional unit to the wiring unit in a rotational manner can include at least one flange coupled to the functional unit and at least one flange coupled to the wiring unit. These flanges operate such that when the functional unit and the wiring unit are coupled together, they are rotated to form a locking connection between the flange on the functional unit and the flange on the wiring unit.
