Abstract: A hypodermic interface assembly is disclosed. The hypodermic interface assembly includes a hub, a cannula, and a cannula carrier. The cannula carrier is non-removably-connected to the cannula. The cannula carrier is controllably separable from the hub.

Abstract: An adjustable glarefoil assembly is provided for mounting to a median barrier which divides opposing lanes of a highway and operates to reduce the glare of headlights from oncoming vehicles. The glarefoil assembly includes a plurality of glarefoil blades which are adjustably coupled for angular movement with respect to a base runner section in an appropriate light blocking orientation. The base runner section is rigidly mounted to the top of the median barrier at between three and five spaced points, thereby preserving some latitude for vibrational movement within the base runner section. The glarefoil blades are each adjustable about a vertical, longitudinal axis so as to optimally provide sight obstruction for a variety of different road curvatures, as well as maintaining the best possible angle to prevent wind build-up.

Abstract: A delineator device having high visibility and utility for attachment to a paving surface such as a median curb or other dividing area between two lanes of traffic. The device includes an integral base member and vertical support member having a top and a bottom end and intermediate section including an elongated concave-convex structure. The bottom end of the vertical support is coupled to an upper face of the base to provide support for an attached horizontal member at the top end of vertical support member. This horizontal member includes top and bottom edges and an intermediate section which is also of concave-convex structure. A receiving base is provided for insertion of a projection tab section which extends downward from the base member. Locking flanges are attached to the tab to enable the device to be secured in its inserted position.
