A porous ceramic atomized cartridge contains a heating element, a porous ceramic wick, and the liquid to be vaporized removably concealed within the body of an electronic simulated smoking pipe. Adjustment of the spacing of a circular disc heating element relative to the porous ceramic wick adjusts the level of atomization. All components are easily removable and replaceable and cleaned. A bowl of the pipe is used as an open battery chamber to allow any battery fumes to escape and allow easy removal and replacement of the battery. A conductive contact arm pivots between contact with the battery and the pipe body to control power. Vapor is activated by a manual push button switch or an automatic sound activated switch responsive to the puffing sound of a user.

A storage area network can include a storage virtualization entity—intelligent storage application resource (iSAR)—either as a separate device in the fabric, or as an integrated module in one or more switches within the fabric. All I / O operations can be re-directed to iSAR for processing. iSAR can segment virtual storage and physical storage into units, where each unit of the virtual storage is mapped to a single unit in physical storage. Data associated with incoming I / O operation can be compressed before being stored in physical storage. iSAR includes overflow reserve storage at the block, sub-page and page level to accommodate changes in compressed data size on subsequent I / O operations. These measures can improve I / O performance and reduce fragmentation. iSAR can also employ deduplication of incoming data stored on physical storage to improve storage efficiency.

A passive optical network (PON) in accordance with the invention uses a superframe having a number of subframes arranged in a two-dimensional array, wherein for normal data transfer subframes are allocated to each optical network unit (ONU) column by column, left to right, and within each column subframes are allocated from top to the bottom. Initially, for ranging, at least two subframes are allocated to an ONU, adjacent to a diagonal of the superframe (which may go from the top left corner of the superframe to the bottom right corner, or alternatively from the top right corner to the bottom left corner). In some embodiments, instead of allocating subframes column by column, the subframes are evenly spaced apart from one another, and conflicts with a previous allocation are resolved by adjustment, and optionally an evaluation function may be used to find an optimal allocation.
