Display device and method of driving the same
A display device includes a housing, a display panel inserted into or withdrawn from the housing. The display panel includes a first display area and a second display area adjacent to the first display area with a boundary line therebetween, a battery which provides a power to the display panel, and a processor which drives the first display area in a display mode, in which the display panel displays an image in a state in which the first display area is withdrawn from the housing and the second display area is inserted into the housing. The processor drives the second display area in a charging mode, in which the battery is charged, in a way such that an average of degradation degrees of second pixels included in the second display area is equal to an average of degradation degrees of first pixels included in the first display area. |

Multi-dimensional printing method and apparatus
Exemplary embodiments of the present disclosure can provide for a transparent panel that can have a featured image which can be surrounded by a pattern of repeating designs on a first side of the panel. A vinyl layer can be provided on the entire first side of the panel to assist in the featured image and repeating designs to be viewable on the second side of the panel (opposite of the first side). On the second opposite side of the panel, an area of the panel where the pattern of designs is visible is provided with a series of lens that can overly the repeating designs. In some exemplary embodiments, the lenses can project enlarged representations of the underlying repeating designs that appear to the eye as occupying a different plane than the featured image, creating a sense of depth within the image. |

System and method for dispersing particles within a toy or ornament and toy or ornament incorporating the same
A method of making a decorative enclosure including providing a display portion having a top opening, a front portion and a back portion. A screen is disposed over the top opening of the display portion. The screen slopes downwards from the back portion to the front portion of the display portion and includes a plurality of screen openings configured to allow passage of particles for the simulation of falling snow within the display portion. |

Interactive education system for teaching patient care
Apparatus and methods according to which a simulated eye includes a simulated iris and a simulated pupil. An iris optical sensor is positioned behind the simulated eye and adapted to: sense a condition of light passing through the simulated pupil; and send, based on the sensed light condition, a first electrical signal. An iris motor is mechanically coupled to the simulated iris and adapted to: receive a second electrical signal; and change, based on the received second electrical signal, a size of the simulated iris. In some embodiments, an iris size sensor is adapted to: sense the size of the simulated iris; and send, based on the sensed size of the simulated iris, a third electrical signal. The second electrical signal may include or be based on the first electrical signal, the second electrical signal, or both. |
