Abstract: In certain embodiments, the present invention includes a method for engaging with a projection of a first component to removably secure a second component to the first component. The method includes positioning a rotatable member of the second component in a first rotational orientation such that the rotatable member is allowed to receive, via a gap in a perimeter of the rotatable member, the projection of the first component. The method also includes positioning the rotatable member in a second rotational orientation such that the rotatable member is prevented from disengaging with the projection of the first component to secure the second component to the first component. The method also includes returning the rotatable member to the first rotational orientation such that the rotatable member is allowed to release, via the gap in the perimeter, the projection of the first component to remove the second component from the first component.

Abstract: In certain embodiments, a port cover for a system integrated into a structure for injection of a material into one or more cavities in the structure includes a base for coupling to the structure. The base comprises one or more ports for injection of the material into the one or more cavities in the structure, one or more slots, and one or more channels each associated with a corresponding slot. A cover for removably coupling to the base to selectively control access to the system includes one or more tabs each adapted to engage with a corresponding slot of the base. The one or more tabs of the cover are adapted to, after sliding downward to disengage from the one or more corresponding slots, move outward substantially perpendicular to the front surface of the base through the one or more corresponding channels to remove the cover from the base. When the cover is removed from the base, the system may be accessed for purposes of injection of the material into the one or more cavities in the structure.

Abstract: In certain embodiments, the present invention includes a key for engaging a locking mechanism for a port cover for use in a system integrated into a structure for injection of a material into one or more cavities in the structure. The locking mechanism is for removably securing a cover of the port cover to a base of the port cover that is coupled to the structure and includes one or more ports for injecting material into the one or more cavities in the structure. The key is adapted to engage with the locking mechanism, and orient the locking mechanism such that the locking mechanism engages with a projection of the base to removably secure one or more tabs of the cover in engagement with one or more corresponding slots of the base to removably secure the cover to the base to prevent unauthorized access to the one or more ports.

Abstract: In certain embodiments, the present invention includes a method for protecting from unauthorized access one or more ports of a system integrated into a structure for injection of a material into one or more cavities in the structure. The method includes coupling a base to the structure, the base including the one or more ports for injection of the material into the one or more cavities in the structure and one or more slots. The method further includes removably coupling a cover to the base to prevent unauthorized access to the one or more ports, the cover comprising one or more tabs each adapted to engage with a corresponding slot of the base.

Abstract: In one embodiment, a port cover for a system integrated into a structure for injection of a material into one or more cavities in the structure includes a base for coupling to the structure. The base includes one or more ports for injection of the material into the one or more cavities in the structure and one or more slots. The port cover also includes a cover for removably coupling to the base, the cover including one or more tabs each adapted to engage with a corresponding slot of the base. The cover also includes a locking mechanism for removably securing the cover to the base to prevent unauthorized access to the one or more ports. The locking mechanism is adapted to engage a projection of the base to removably secure the one or more tabs of the cover in engagement with the one or more corresponding slots of the base to removably secure the cover to the base to prevent unauthorized access to the one or more ports.
