Abstract: A mobile point-of-sale system includes a cart frame and a battery housed in the cart frame. The cart frame includes a front having a bottom, a back having a bottom edge and a bottom. The bottom includes a pair of upper flanges and a lower housing. The pair of upper flanges have components for receiving wheels for supporting the cart frame and the lower housing includes at least one aperture for venting heat from the battery that is supported by the lower housing. At least a portion of the lower housing and the battery are located below the pair of upper flanges and are located below the bottom edges of the front and the back.

Abstract: A lockable electronic tablet stand is described that fixes the tablet in a locked relation to the stand. The stand actuates between a locked and unlocked position and provides an intuitive locking system. Use of a key is required for removal of the tablet from the stand.

Abstract: A system for providing support and position control of a monitor. In one embodiment, a method of supporting a monitor includes converting an ascending energy storage member force curve into a substantially constant supporting force against the monitor. In one aspect, a method of supporting a monitor includes providing an energy storage member and a cam which are cooperatively positioned so as to move relative to each other along the path of motion. As the energy storage member moves along the path relative to the cam, the cam displaces the energy storage member and thereby changes a force applied by the energy storage member on the cam, and wherein the cam converts the force applied by the energy storage member into a supporting force on the monitor.
