Abstract: There is provided a workbook having a plurality of pages, Each page having a writing surface suitable for writing with a dry erasable pen and allowing erasure of the writing. The writing surface is formed on a substrate by applying layers of film. A particular embodiment uses two film layers. A first layer of water-based UV film is covered with a second layer of UV film having a gloss finish.

Abstract: A wall or roof covering for mounting to a support surface, comprising: a plurality of panels securable to the support surface, each of the panels having a front surface comprising a covering section with simulated building elements, an opposed rear surface facing the support surface when secured thereto, a first marginal edge region and an opposed second marginal edge region, the first marginal edge region having an elongated receiving groove with an elongated aperture oriented one of substantially upwardly and substantially downwardly, the second marginal edge region being at least partially insertable in the first elongated receiving groove of a vertically-adjacent panel and being at least partially covered by a first section of the covering section of the vertically-adjacent panel when inserted therein.

Abstract: A corner assembly for siding and roofing coverings includes two complementary corner molding members, each one of the two corner molding members having a front wall including a covering section with simulated building elements on an outer face thereof. Each one of the two corner molding members further has at least one protruding finger and at least one recess. The at least one protruding finger and at least one recess are configured in an alternate configuration in order to interlock in a male-female configuration when the two complementary corner molding members are engaged with one another to define a corner. A method covers a length of a corner defined at a junction of a first support surface and a second support surface.

Abstract: A wall or roof covering for mounting on a support surface includes a plurality of panels securable to the support surface. Each panel has a front surface including a covering section with simulated building elements, an opposed rear surface facing the support surface when secured thereto, an upper marginal edge region and an opposed lower marginal edge region overlying the upper marginal edge region of a vertically-adjacent panel. One of the upper marginal edge region and the lower marginal edge region has an inclined receiving slot defined therein, the other one of the upper marginal edge region and the lower marginal edge region has an inclined insertable flange engageable in the inclined receiving slot of the vertically-adjacent panel.

Abstract: A method and apparatus for matching the contents of a container with information pertaining to its use. In an embodiment, the method is used for matching a beverage with a meal. The method comprises providing an identification of a given one of the beverage and the meal, the identification defining uniquely the given one of the beverage and the meal; accessing a database comprising a table associating each of a plurality of beverages with a corresponding one of a plurality of meals; querying the database using the identification; and the database returning a subset of a corresponding identified ones of the plurality of beverages and the plurality of meals. Alternatively, the method is used for finding medicinal information associated with a medicinal product.

Abstract: A self-locking system comprising a state selector for detecting the intent of an occupant to rise from a chair and then automatically causing a lock to block the mobility functions of the chair. The state detector is responsive to movement of an upper portion of the body of the occupant while the occupant is still supported in a normal seated position on the seat of the chair, thereby advantageously allowing the locking of the mobility functions of the chair to occur before the occupant starts to lift his weight from the seat of the chair.
