Abstract: Disclosed are transceivers for communicating with wireless memory devices integral with replaceable printing components, the transceivers configured to separately access multiple antennas for selectively communicating with a plurality of memory devices. Also disclosed are printing systems incorporating such transceivers.

Abstract: A method of determining the location of a movable icon on a display surface in a digital light projection system is disclosed. The method includes projecting modulated light to the display surface to generate a viewable image and projecting an identifiable optical signal to the display surface with the viewable image such that said viewable image is not observably degraded. The identifiable optical signal is receivable by the icon on the display surface.

Abstract: A system and method for collecting and processing physical data obtained by various detection devices mounted to a vehicle, such as an aerial craft. Specifically, the present illustrated embodiment(s) involve the use of an aerial craft, such as a helicopter, to capture continuous visual, spatial, and related physical data, and a method for selecting certain representative pieces of the captured unprocessed data to create a discrete stream of processed data. The discrete data stream may then be analyzed and any defects and/or anomalies may be identified within the physical data.
