摘要: A handheld message board is provided. The message board includes a front portion and a back portion. The front portion may be made of an erasable writing surface, such as a chalk board or a dry-eraser board. The present invention may further include a handle attached to the back portion so that a user may easily grasp the handheld message board and write on the front portion. The handle includes a strap having a first end and a second end. The first end and the second end are attached to the back portion forming a loop in between to secure a user's hand.

摘要: In one embodiment of the invention, photo-chromic toys are disclosed. A photo-chromic toy includes a photo-chromic material such as a photo-chromic ink, paint, plastic, or dye. The photo-chromic material may be supplied in a material of the toy or applied to a surface of the toy at the factory. The photo-chromic material may be activated in various ways with various light activating devices that can generate the activating light with appropriate wavelengths.

摘要: A writing surface has a phosphorescent or fluorescent material thereon that has an excitation energy that is less than the photon energy emitting from a penlight stylus light source or emitted through a transparent writing surface. The phosphor security ink is selectively excited only where exposed to light emission from the stylus thereby creating a phosphorescent or fluorescent glow visible under low ambient light conditions. The phosphorescent material is adhered to the writing surface or decorates a ferrite particulate which is drawn onto the writing surface through the influence of a magnet.
摘要翻译: 书写表面上具有磷光或荧光材料,其具有小于从手电筒光源发射或通过透明书写表面发射的光子能量的激发能。 磷光体防伪油墨仅在暴露于来自触针的光发射的情况下被选择性地激发,从而在低环境光条件下产生可见的磷光或荧光发光。 磷光材料粘附到书写表面或者通过磁体的影响来装饰被写到书写表面上的铁氧体颗粒。
