An article for mounting to a vertical surface comprising a substrate having a first layer formed from a flexible film or sheet and a second layer formed with a conventional low-tack non-reactive reusable adhesive effective for attaching the substrate to drywall or plaster or wood surfaces. At least one rigid component is attached to the substrate. The second layer covers at least a portion of the first layer for attaching to a vertical surface and includes a release area, wherein the release area is positioned such that it is vertically above the at least one rigid component. The rigid component operates to produce a cantilever moment and wherein the release area operates to counteract the cantilever moment.

A device for testing cognitive development of a user; the device includes a housing and a test-member. Further, in a preferred embodiment, the device includes a cover-portion and a plurality of test-blocks. The device is useful for testing the cognitive development of the user by providing a revolving-test member including a plurality of test-displays each having a different development topic for testing.

Apparatus and methods are disclosed for sealing openings on containers and other structures, permitting selective removal of portions of the seal structure, and for similar selective removal of portions of adhesive elements such as bandages.

A multi-component collapsible and portable shape-sorting learning and development toy including a soft housing, an aperture plate element with a plurality of openings together with a matching number of blocks adapted to be inserted in the openings of the aperture plate element, a photographic display element, and a baby-safe mirror element. The toy and the individual component parts are adapted to a variety of uses for play.

A manual dexterity device has a base and a lid. The base includes a bottom and three side walls that form an open top. The lid is received on said base at the top opening and is movable between a closed position in which the lid closes the top opening and an opened position in which the top opening is open. A plurality of slots are arranged on the lid in rows and columns. The slots are configured to receive test or control objects that test the manual dexterity of a user. Test objects passing through any of said one or more slots are received in the base.

An amusement activity station enables a user to operate complex machinery to pick up and position selectively shaped objects in a safe and amusing manner. The amusement activity station includes a complex machine component and at least one object-receiver station. The complex machine includes a user position station, a user-to-machine interface, a moveable member, and a pick-up mechanism. The moveable member is maneuvered relative to the user position station by way of manual operation of the user-to-machine interface. Each object-receiver station includes at least one object-receiving structure. The pick-up mechanism and moveable member are directable for picking up and conveying selectively shaped objects toward the object-receiving structure(s) for positioned placement. The amusement activity station contemplates any number of shapes and sizes of the object-receiving stations and selectively shaped objects, including basically shaped objects and stations as well as irregularly shaped objects and stations.
