发明名称 Passive infrared display devices
摘要 An advertising and display device includes apparatus to provide automation so as to interact with persons in the area by means of passive infrared sensing devices. The advertising and display device may take the form of a rotating platform or representation of a being or animal, and may incorporate an audio message delivery system also activated by the physical proximity of persons detected by the infrared sensors. The sensing system may be remotely located to enable the advertising and display device to be placed within an enclosure such as a showroom window, etc., and the display platform may incorporate a photoelectric detector to temporarily stop the drive system when a person is in extremely close proximity in order to allow that person to more closely examine items located on the platform.
