Abstract: A wear plate assembly includes a base, a wear plate, and a key. The wear plate is moveable with respect to the base between free and applied conditions. In the applied condition of the wear plate, the base and the wear plate cooperate to form a keyway for receiving the key. The keyway is located below the top of the base. The key is moveable between a first position corresponding to an unlocked configuration of the wear plate assembly and second position corresponding to a locked configuration of the wear plate assembly.

Abstract: Method and apparatus for counting vehicles at entrances, exits and transition zones of multi-story carparks, including particularly where the ceiling heights can be just marginally higher than the tallest expected vehicle, with a view to determine the carpark occupancy at different carpark levels by counting passing vehicles using a vision-based car counting system without relying on viewing test patterns or employing a blocking beam scheme and yet tolerating vehicles transgressing partially or fully into the wrong lane of a two-lane two-way road while ignoring vehicles moving opposite to the expected direction. Without imposing additional constraints to ambient carpark illumination, the methodology copes with highly specular vehicle surfaces, ignores non-vehicular objects and detects moving cast shadow or highlight, and adapts to daily and seasonal scene changes, and yet estimates vehicle speed.

Abstract: A stacked food storage apparatus includes a first container having a lid with an outer surface. Discontinuous first and second protuberances are carried by the lid and extend upwardly with respect to the lid. A second container includes a base having opposed inner and outer surfaces. Discontinuous first and second sockets are formed in the base and extend upwardly with respect to the base. The second container moves between a free position and a stacked position with respect to the first container. In the stacked position of the second container, the first and second protuberances releasably nest with the first and second sockets, respectively. Interference fits between the first protuberance and the first socket, and between the second protuberance and the second socket, attach the first container to the second container and restrict relative movement of the first container with respect to the second container.

Abstract: A retaining device for retaining an object or objects to a surface or surfaces. The device includes an elongate, flexible strap having a plurality of bores and a retaining member embedded within a platform body. The retaining member has first and second portions. The first portion has a first end which is passed through one or more of the bores of the strap to operatively connect the strap to the retaining member. The strap is placed around the object to be retained. The second portion retains the first portion in a closed position so that the object is retained securely but non-permanently. An adhesive between the platform body and the surface permanently fixes the retaining device to the surface.
