Abstract: A system for selecting one of multiple paths in a linear drive system includes track segments having a first drive member and at least one mover having a second drive member for the linear drive system. Each mover includes a drive surface oriented toward the track segment when the at least one mover is driven along the track. Each mover also includes a first channel and a second channel extending along the drive surface. A switch track segment includes a first path and a second path along which the at least one mover may travel, at least one first pin positioned along the first path, and at least one second pin positioned along the second path. The first and second pins are extendable to engage the first and second channels of the at least one mover to direct the mover along either the first path or the second path, respectively.

Abstract: Techniques for creating and using error tables to track errors associated with a base table are described. A command to perform an operation on a base table stored in a network-based data system can be received and executed, causing at least one error. At least one error record corresponding to the at least one error can be inputted into an error table, which is nested with the base table. Contextual information can be added to the at least one error record.

Abstract: A gate assembly is provided for positioning in an opening through which selective entry is required. The gate assembly includes barrier means mountable directly or indirectly to one or more surrounding surfaces defining said opening, and hinge means to allow said barrier means to be movable relative to said surrounding surfaces in use between a closed condition, wherein the opening is closed, to an open condition, wherein the opening is open. The hinge means are arranged so that the barrier means and/or hinge means has an axis of pivot which is at an acute angle to a vertical axis. Resilient biasing means are associated with the hinge means to help bias the barrier means from the open condition to the closed condition in use. The resilient biasing means act in a direction along a substantially horizontal axis or along an axis substantially transverse or perpendicular to the axis of pivot of the barrier means and/or hinge means.

Abstract: A securing means for use on a barrier such as a child safety barrier and/or the like where the securing means includes a housing, stopper means that are movable relative to said housing between an extended position, wherein the stopper means protrude outwardly from said housing to allow engagement of the stopper means with a suitable surface in use, and a retracted position, wherein the stopper means is in a retracted position with respect to said housing relative to said extended position to allow disengagement of the stopper means from a suitable surface in use. The securing means includes cam means and movement of said cam means results in movement of said stopper means between said extended and retracted positions.

Abstract: A barrier means suitable for use as a child safety gate, said barrier means including hinge means to allow the barrier means to be hingedly moved between a first closed position, wherein access past the barrier means is substantially prevented, and a second open position, wherein access past the barrier means is possible. User actuation means are provided on or associated with said hinge means, and actuation of said user actuation means allows said hinge means to be moved from a first engaged position to a second disengaged position.
