Abstract: In some examples, a server may receive, by a menu manager executing on the server, a menu having a particular format from a point-of-sale (POS) terminal and parse the menu to create a parsed menu. The menu is parsed using POS data indicating a formatting of the menu. The server automatically converts the parsed menu into multiple menu items, stores the multiple menu items in a menu item database, and creates a mapping database that includes pricing data, pronunciation data, and voice tags associated with individual menu items of the multiple menu items. The server provides multiple software agents access to the mapping database and instructs individual software agents of the one or more software agents to initiate a conversation with a customer to receive a voice-based order. The individual software agents comprise an instance of an artificial intelligence engine.

Abstract: A display comprises a display device having an image output surface at which an image is displayed as a spaced array of pixel elements, a light transmitting element in the form of an image guide having a viewing surface, the light transmitting element arranged to receive light from the display device and display the received light on the viewing surface, the light transmitting element having a polarising layer arranged in an optical path between the display device and the viewing surface, wherein the polarising layer is arranged to attenuate unpolarised ambient light received from outside the display while substantially transmitting polarised light received from the display device.

Abstract: An image display comprises an image display device for generating a viewable image; and an optical angular selector for selecting an angular range of light to form the viewable image, the optical angular selector having an array of substantially parallel light transmission guides each comprising a light-guiding region to promote propagation of light incident upon the light-guiding region within a range of angles of incidence by refraction and/or total internal reflection and an absorbing material peripherally arranged with respect to the light-guiding region to absorb light incident upon the light-guiding region outside the range of angles of incidence.

Abstract: An image display comprises an image display device having an array of pixel elements; and an image guide having an array of light transmission guides (80), input ends of the light transmission guides being arranged to receive light from pixel elements of the image display device, and output (90) ends of the light transmission guides providing an image output surface; in which each light transmission guide comprises a light-guiding region to promote light propagation by total internal reflection and a reflective coating (86) on the light guiding region to promote specular reflection at the region-coating interface.

Abstract: An image display comprises: a display device having an image output surface at which an image is displayed as a spaced array of pixel elements; an image guide (20) coupled to the image output surface of the display device and comprising a plurality of light transmission guides (80) each having an input end and an output end, the input ends of the light transmission guides being arranged relative to one another so that groups of one or more light transmission guides receive light from respective groups of one or for a cluster comprising at least a subset of the light transmission guides (80): at the outer periphery of the cluster, the input ends of the light transmission guides are constrained against expansion by a frame formed of a material having thermal expansion properties which are substantially similar to the thermal expansion properties of the image output surface.

Abstract: An image display comprises an image display device having an array of electrically driven picture elements (60) viewable at a viewing surface (90); and luminance correction means (110) arranged with respect to the image display device so as to apply a spatial luminance filter (122, 124) to the output of the image display device, the spatial luminance filter attenuating the light output by each picture element of the image display device in substantially inverse relation to the luminance response characteristics of the picture element so that each picture element exhibits substantially the same luminance for a given input electrical driving signal.

Abstract: A spacer (60) for spacing the screen of a flat panel display from the backplate of the display comprises an extrusion (62) formed from a dielectric inorganic material for supporting the screen relative to the back plate, and a layer (64) of attachment material located at one end of the extrusion (62) for attaching the extrusion (62) to the backplate of the display. The spacer (60) has a cross-shaped cross section providing increased stability, without a significant increase in visibility.
