20090016204 | Thin Optical Disc Having Remote Reading Capability - In accordance with the teachings of the present invention, a thin optical disc having remote reading capability is provided. In accordance with a particular embodiment of the present invention, the optical disc includes a central clamping area that defines a central aperture operable to be engaged by a spindle mechanism of an optical disc drive, an optically-readable data storage area substantially surrounding the central clamping area, the optically-readable data storage area having a planar thickness of less than 1.20 mm, and an electronic tag coupled to or embedded within the optical disc, the electronic tag comprising a radio frequency tag or radio frequency identification tag. | 01-15-2009 |
20090052309 | OPTICAL DISC COMPRISING RF TRANSPONDER - An optical disc having a center, an outer periphery and a metal layer between the center and the outer periphery. A tag comprising a radio frequency transponder is located in a region adjacent the outer periphery. This arrangement facilitates reading the transponder with an external reader when a plurality of discs are stacked one on top of the other. | 02-26-2009 |
20090285083 | ACTIVATION SYSTEM AND METHOD FOR ACTIVATING AN OPTICAL ARTICLE - An optical article comprising a plurality of optically detectable marks disposed on a surface of the optical article; a removable electrical device disposed on the surface of the optical article; wherein the electrical device is operatively coupled to the optical article; and wherein the electrical device is configured to interact with an activation signal when brought in direct contact with a communication device that applies the activation signal to the electrical device. A removable electrical device is also provided. A system and a method for activation are also provided. | 11-19-2009 |
20090316565 | METHOD AND SYSTEM FOR ACTIVATION OF AN OPTICAL ARTICLE - A method for activating an optical article includes providing an optical article, wherein at least one mark is disposed on the optical article, wherein the mark comprises an optical-state change material in an initial state, the initial state preventing the optical article from being read by a player; deriving an unlock code by cryptographic operations on an optical article operatively coupled with a POS equipment and a data input from a medium encrypted with a cryptographic algorithm; deriving a toggling signal from an unlock code, and applying the toggling signal to the at least one mark resulting in changing the optical-state change material to a final state, the final state allowing the optical article to be read by the player; wherein the toggling signal comprises a set of values corresponding to the respective states of each of a plurality of marks on the surface of the optical article, and wherein applying the toggling signal results in setting each of the marks to either one of an initial state or a final state, corresponding to the value for the mark in the toggling signal. | 12-24-2009 |
20100039920 | IDENTIFICATION BASED PRODUCTION AND FURTHER PROCESSING METHOD OF AN OPTICAL PRODUCT, E.G. A LENS OF A MOBILE PHONE, FOR VERIFYING GENUINENESS AND TRACEABILITY OF A DEVICE WHICH INCLUDES AN OPTICAL PRODUCT - A method for producing an optical product, such as a lens of a mobile phone, wherein in the production and further processing method an identifier ( | 02-18-2010 |
20100046352 | Method of manufacturing a limited use data storing device - Embodiments of methods and systems for controlling access to information stored on memory or data storage devices are disclosed. In various embodiments, methods of retrieving information from a data storage device previously deactivated by modification or degradation of at least a portion of the data storage device are disclosed. | 02-25-2010 |
20110194399 | Radio frequency transponder for use with a medium - A radio frequency transponder for use with a disc, such as a CD or DVD has an antenna formed by depositing a conductive solution on a surface of disc outside at adjacent to its outer periphery outside of the disc storage area to yield at least one conductive region. A transponder circuit is coupled to the antenna for supplying an RF signal to the antenna in response to a signal received from the antenna. | 08-11-2011 |
