Abstract: A digital watermarking system in accordance with these teachings includes a mobile device having a image capture sub-system for generating digital data representative of an image. Information related to the image at the time of imaging is used as input information for the digital watermarking software. The related information may be stored separately from the image, and subsequently included in the image by remote processing. Appropriate components are included in the device for imaging, processing and communicating with other apparatus. Digitally watermarked images can be stored in the mobile device, or transferred through the wireless link to a data communications network, such as the Internet. These teachings also pertain to methods for using the mobile device and related systems.

Abstract: A bandage includes at least one layer, where the layer further includes a light emitting material. The light emitting material may be evenly distributed throughout the layer, printed or coated on a surface of the layer, or may form an ornamental design on a surface of the layer. The light emitting material may also be printed as text on, or incorporated into the layer, thus allowing such text to be read in low light or dark conditions.

Abstract: A method and apparatus for identifying an object include encoding physical attributes of an object where the encoded information is utilized as at least one element for composing a digital watermark for the object. In another embodiment the physical attributes of an object are utilized as a key for accessing information included in a digital watermark for the object. In a further embodiment, a digital watermark is incorporated into a bar code. As another aspect of this embodiment, information may be encoded into the digital watermark of the barcode and may be decoded or otherwise retrieved by the use of a key. The digitally watermarked bar code may function in a conventional manner or may also include a “pass key” to allow reading of the bar code itself.
