摘要:
A perishable media system including a media writer for writing information to a perishable media information storage mechanism, a media reader for reading information written on the perishable media information storage mechanism, a data access eliminator for eliminating access to the information written on the perishable media information storage mechanism, and an interpretation mechanism. The system operates by writing information to the perishable media information storage mechanism with the media writer, thereafter reading the information with the media reader. Once the information is read by the media reader and interpreted by the interpretation mechanism, the data access eliminator, in the form of a light, magnetic field, or bias eliminates access to the information.
摘要:
A non-speckle laser projection display composed of a liquid crystal material for the generation of a high resolution, non-speckle image. The projection display screen includes a liquid crystal material which is constructed in a highly scattered state when no drive voltage is applied. When a high frequency, low voltage signal is applied to the liquid crystal projection display screen, the liquid crystal molecules vibrate slightly at a frequency higher than 60 Hz, thereby causing the speckle pattern to change quickly, and causing the eye to smooth out and see no speckle. In addition, provided is a non-speckle laser display system in which included is a laser image source and the liquid crystal projection display screen.
