A stand for a touch screen device, including a base including at least two wheels, wherein the wheels are retractable within the base. The stand also includes a frame including a first end and a second end, attached by its first end to the base. Furthermore, the stand includes a support for the touch screen device, attachable to the frame at the proximity of the second end of the frame. The support includes means for rotating the support with respect to the frame and means for locking the support with respect to the frame. The stand also includes a battery and means for connecting the battery to the touch screen device.

Superior usability is provided and the degree of freedom in terms of use is enhanced. A plurality of link members A1 and A2 include at least one of linear edges A12 and A22 at the peripheral edge of a facing surface A10 or A20 that faces in a folded state. At least one of the adjacent link members A1 and A2 is a magnet, and the other is a material attracted by the magnet. A link body A is formed of the link members A1 and A2 that are linked by the attracting force due to the magnetic force of the link members A1 and A2, of which the linear edges A12 and A22 are aligned.

The present invention relates to a metal-sheet board or blackboard with magnetic features having two or three movements, which plots and represents reality in four dimensions (horizontal, vertical, depth and time) and which describes reality objectively, in which a T-shaped ruler is moved on a rail along the horizontal or X axis by a digital stepper motor controlled by a driver and software on the computer (horizontal movement). Furthermore, a tool truck surrounding the T-shaped ruler moves along the entire length (vertical movement) or Y axis thereof, actuated by a digital stepper motor controlled by a driver, which is in turn controlled by software on the computer, with these two movements controlled by mathematical speed and acceleration functions.

A magnetic display unit includes: a display layer; a magnetic layer located behind the display layer; and a quick-release mechanism including an activator, wherein the quick-release mechanism is adapted to increase the distance between the magnetic layer and the display layer such that, when activated by the activator, the quick-release mechanism causes any magnets located along the display layer to be released from the display layer.

A disposable grocery cart cover for decreasing the risk of infection for children placed in grocery carts by providing a sanitary lining system. The grocery cart cover may include a planar cover material adapted to fit over a child seat of a grocery cart. The planar cover material may have a center portion and an outer edge portion. The grocery cart cover may also include two holes located in the center portion of the planar cover material and adapted to receive two legs. The grocery cart cover may further include two slits adapted to receive a safety strap and a drawing surface holder. A packaging system allowing disposable grocery cart covers to be distributed to grocery cart users in an efficient manner is also provided.
