An information display system comprises a controller, a ceiling node, a rail, an end cap and a solar powered display module. The display module stores and displays information. The controller communicates with the end cap through an IR downlink and an RF uplink, and the end cap communicates with the display module by wired communication. By uniquely combining RF and IR communication systems in the information display system, communication between the controller and the module is fast and accurate and the display module's power consumption is significantly reduced to make a solar powered information display system practical. By a unique power bus, excess power is shared.

Solar powered price display system

A module for displaying information which is electronically controllable and information which is not so controllable. Substantially the entire front (visible) face of the module is divided into two portions. One is the face of a LCD display. The second is the face of a solar cell. The face of the solar cell is covered by a transparent overlay which bears the non-controllable information.

Display module

A system is provided for reading an image stored on a storage layer radiation screen. The system includes a carousel for holding a storage layer radiation screen and a screen scanning system. The screen scanning system includes a carousel mount on which the carousel may be mounted and a rotation mechanism for rotating the carousel mount, rotation of the carousel mount serving to rotate the carousel about a rotational axis which, in turn, causes the screens held on the carousel to move in a circular path about the rotational axis. The carousel is preferably removable from the carousel mount. The screen scanning system also includes an image acquisition optical system positioned adjacent the circular path of the screen, the image acquisition optical system including an excitation system for focusing an excitation beam on a portion of the screen to cause a light emission, and an emission collecting system for collecting the light emitted from the screen. The screen scanning system may further include an optics driver for moving the image acquisition optical system in a direction parallel to the rotational axis of the carousel. A method is provided for reading images stored on multiple storage layer radiation screens. The method includes attaching multiple storage layer radiation screens to a carousel, rotating the carousel about a rotational axis such that the screens move in a circular path about the rotational axis, focusing an excitation beam at a point on the circular path such that the portions of the screens passing the point on the circular path emit light, collecting the light emitted, and moving the point on the circular path on which the excitation beam is focused in a direction parallel to the rotational axis.
