Abstract: A new infrastructure for mobile devices and electronic loose equipment, preferably an aircraft infrastructure, is designed to be deployed for both new production aircraft and the after-market installed base for all parts of the aircraft that have human interaction, such as the galley, cockpit or cabin. The architecture is designed around two main objectives: creating stylized and functional products with flexibility in design and providing reliability and maintainability for operators while integrating power and charging mediums to those devices. This architecture is composed of several elements that as a whole complete our new architecture for mobile devices and electronic loose equipment design.

Abstract: An eye fundus camera having an automated focus control system which includes a mark projecting system for projecting a focus detecting mark to the retina of a patient's eye to produce a mark image and a photoelectric system for detecting the mark image to judge the focus condition. The photoelectric system produces electric signals which are compared with a threshold level signal to produce mark image signals. In order to ensure an accuracy of detection of the mark image, the threshold level can be changed when it is judged as inappropriate.
