A greeting card has a removable memento. The greeting card is one or more panels having a cutline extending entirely through the thickness of the greeting card. The portion of the card having a periphery defined by the continuous cutline acts as a. The greeting card may also have a coextensive second layer formed from paper, poster board, cardboard, a wooden panel, a photograph and the like. The greeting card may also be have two equally sized wooden panels attached to the same side of a second layer capable of forming a bendable hinge or joint between the two panels, allowing the two wooden panels to be rotated about the hinge 180° or 360°.

An image display device for displaying wall art, comprising: a transparent top layer comprising a thermoplastic polymer, wherein the transparent top layer comprises a first side and a second side, and wherein the top layer overlays a viewing side of at least one image.

A paint composition includes a fluid and a coloring agent in the fluid. The fluid maintains the coloring agent in a first protonation state. The coloring agent exhibits a first color characteristic in the first protonation state. The paint composition includes microcapsules in the fluid. The paint composition also includes a chemical compound in the microcapsules. Rupture of at least a portion of the microcapsules is configured to release the chemical compound and expose the coloring agent to the chemical compound. Exposure of the coloring agent to the chemical compound changes the coloring agent from the first protonation state with the first color characteristic to a second protonation state with a second color characteristic. The second color characteristic is visually distinct from the first color characteristic.

A foldable display device includes a shell. The shell has an expanding state and a folding state. A first direction and a second direction are defined to be orthogonal. When the shell is at the expanding state, the shell has a first length L1 along the first direction and a second length L2 along the second direction. The ratio of the first length L1 to the second length L2 is between 1.3 and 2. When the shell is at the folding state, the shell has a third length L3 along the second direction and a fourth length L4 along the first direction. The ratio of the third length L3 to the fourth length L4 is also between 1.3 and 2.

Portable display boards of the type commonly used for business and educational presentations in conferences, trade shows and fairs, for example, that can be made from a variety of materials including foam board and rigid paper pulp are provided with multimedia device mounts for attaching a multimedia device to the front face of a display board, base stands, and protective corners.

A display apparatus includes a substrate including a first area, a second area, and a bending area, the bending area disposed between the first area and the second area and bending about a bending axis running along a first direction; a first piezoelectric device disposed over the bending area; and a pressure sensor. The first piezoelectric device is configured to contract or expand according to a pressure variation sensed by the pressure sensor.

There is provided a sheet-like article with a string enabling use in two use forms (a first use form and a second use form). A sheet-like article 1 with a string has a first use form and a second use form. The sheet-like article 1 with a string includes a sheet-like main body 2, and a string body 4 inserted into holes 3 of the main body 2. In the sheet-like article 1 with a string, change from the first use form to the second use form is possible by pulling of the string body 4.

A magnetic spinning toy comprising: a top magnetic assembly; a bottom magnetic assembly; a rod, wherein said rod extends between the top magnetic assembly and bottom magnetic assembly; a plurality of rotating wings mounted on the rod between the top magnetic assembly and bottom magnetic assembly; and a mounting arm, wherein the mounting arm receives top magnetic assembly, the plurality of rotating wings and bottom magnetic assembly. The top and bottom magnetic assemblies preferably also include a copper tube with embedded magnets, wherein the embedded magnets include a donut magnet at one end of the copper tube and additional magnets at the mid point and opposite end of the copper tube.

Module for playing a plurality of promotions, including: a plurality of fixtures sequentially configurable into the plurality of promotions by rotating at least one fixture while maintaining an original position of each fixture within the reconfigurable module, each fixture including a plurality of sides; and a plurality of fasteners to combine the plurality of fixtures into the reconfigurable module. Key words include corrugate, modular, and rotate.
