摘要： The invention provides methods for embedding digital watermarks for authentication of printed objects, and corresponding methods for authenticating these objects. One aspect of the invention is a method of embedding a digital watermark in a digital image to be printed on an object. The method embeds an auxiliary signal in the digital image so that the auxiliary signal is substantially imperceptible, yet machine readable. It converts the image to a halftone image using an inherently unstable halftone screen structure that is likely to cause ink flow errors when reproduced. The errors introduced by reproducing the unstable halftone screen structure incorrectly are automatically detectable by reading the auxiliary signal.

摘要： Methods for integrating digital watermarks into holograms, watermarked hologram structures, and related applications. One method creates a watermark image, and then embeds the watermark image into a holographic structure. The holographic structure is created using computer generated holography to create a digital representation of the holographic structure. This digital representation is recorded on a physical substrate using optical techniques or microlithography. As an alterative, a watermark signal is embedded in a physical holographic structure by embedding the signal into an image that is optically merged with the holographic structure as it is optically recorded, or by embedding the signal into an image or physical model from which the holographic structure is formed. Another approach the creates a halftone watermarked image, and forms the halftone watermarked image in the hologram by creating hologram dots corresponding to the dots in the halftone watermarked image.

摘要： Space-time solutions are determined by exchanging pings among nodes in a network. Each ping includes a current space-time state of the transmitting node, which includes the transmitting node's currently estimated location and corrected time (as a count stamp). A particular node in the network receives pings from the other nodes in the network and uses the data in the received pings to estimate its own current position and to correct its own free-running clock relative to a common system time. As a service to the network, the particular node then transmits its corrected time (as a count stamp) and estimated position to the other nodes. In some embodiments, the space-time solutions discussed herein are used as backup to other navigation systems, such as the Automatic Dependent Surveillance-Broadcast (ADS-B) system.
