摘要:
A system for selectively enabling or disabling an optical device. In an illustrative embodiment, the system implements an optical-device theft-prevention system. The theft-prevention system includes a material that is selectively positioned on, in, or relative to the optical device so that the transparency of the material affects a desired operation of the optical device. An energy beam is selectively employed to enable or disable the optical device by affecting the transparency of the material. In a specific embodiment, the fist material includes a dye, such as an energy-sensitive dye. The optical device includes an optical disc, such as Compact Disc (CD) or Digital Video Disc (DVD). The energy-sensitive dye is disposed over an entire readable surface of the optical device.
摘要:
A method and apparatus for controlling access to a storage medium, such as an optically readable medium. Light sensitive or other materials that are adapted to change state and affect reading of a storage medium are used to control access to data that may be stored on optical medium and/or to control use of the medium.

Devices and systems for biomarker detection . In at least one embodiment of a diagnostic testing device of the present disclosure, the device comprises a fluid collector to collect a body fluid, and a housing, to test and retain the body fluid. The housing, in at least one embodiment, comprises a collection chamber, having an open end, to receive the fluid collector and contain a stabilization reagent, at least one membrane test strip, to indicate the presence or absence of at least one diagnostic marker, and an immunoassay-based fingerprint acquisition pad in fluid communication with the collection chamber.
摘要:
The invention relates to methods for manufacturing an optical devices and optical devices incorporating optical blocking material on the read-side surface of the optical disc. A protective layer and an optical blocking material are applied to the read-side surface of an optical disc. The protective layer, for example, may prevent corrosive solvents in the optical blocking material from damaging the read-side surface of the optical disc. Applying the optical blocking material to the read-side surface of the optical disc may prevents an optical disc player from reading the optical device until the optical blocking material deactivated. Once activated, the optical blocking material becomes sufficiently transparent to allow the optical disc player to read the optical disc.
