Patent number: 8122196Abstract: 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.Type: GrantFiled: October 30, 2006Date of Patent: February 21, 2012Assignee: NetApp, Inc.Inventor: Ian Jen-Hao Chang

Publication number: 20110042374Abstract: 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.Type: ApplicationFiled: June 4, 2010Publication date: February 24, 2011Inventor: Jen Hao Chang
