Patent number: 9744799Abstract: An erasable slate system includes a translucent layer adjacent a colored bottom layer, wherein application of a force to the translucent layer causes temporary adhesion of the translucent layer to the colored bottom layer in an area wherein the force is applied. The erasable slate system further includes an extending channel in fluid connection with the translucent layer and the colored bottom layer. The extending channel extends around at least 25% of the length of a perimeter of the bottom colored layer. The erasable slate system further includes an air pump in fluid connection with the extending channel via which pressurized air can be introduced into the extending channel to cause the translucent layer to be separated from adhesion to the colored bottom layer, thereby erasing markings, and via which air can exit the extending channel of the erasable slate system.Type: GrantFiled: June 26, 2015Date of Patent: August 29, 2017Assignee: LIG SCIENCES, INCInventor: Sang Beom Lee
