  • Publication number: 20210364817
    Abstract: A display system includes an optical element positioned in the optical path to receive light from the display module and direct the light into a field of view to display a scene. The optical element has a focal length on an optical axis of the optical element that varies in response to a control signal. A control system is programmed to generate the control signal to cause the optical element to cycle through a series of focal lengths at a frequency. Each focal length of the series corresponds to a focal plane of a series of focal planes. The control system is programmed to vary the light field from the display module to display the scene as a sequence of different image frames, the different image frames being synchronized so that each of the different image frames is presented at a corresponding one of the series of focal planes.

  • Patent number: 8122196
    Abstract: A procedure and system reduces latency in restoring encrypted or compressed and encrypted data through a security appliance. The security appliance is coupled to a sequential access device and is configured to encrypt or compress and encrypt data provided by an initiator for secure storage on a sequential access device. To that end, the security appliance intercepts a read request issued by an initiator to access the data stored on the device, and forward the request to the device. Upon return of the requested data from the device, the security appliance restores (decrypts or decrypts and decompresses) the data prior to returning it to the initiator. The appliance also issues a “read ahead” (retrieve beyond the request) request to the device for predetermined amount of additional data for caching on the appliance.

  • Publication number: 20110042374
    Abstract: A drink up consists of a lower cup body, an upper cup body, and a lid. The top of the lower cup body has an opening for holding drink and ice. The upper cup body connects to the lower cup body, with a cup opening for drinking or for a straw to be inserted. The lid closes the cup opening. One adds a drink or ice via the opening into the lower cup body. After the combination of the upper cup body and the lower cup body, one can directly have the drink via the cup opening or a straw. The addition of ice can elongate the keep time of soda gas. The drink therein can be kept at a better taste and coldness for a longer time. By opening the upper and lower cup bodies, the user can readily clean and reuse them. The invention is recyclable.
