Cache eviction
A method and apparatus for downloading content within a video-on-demand system is provided herein. During operation a Video Home Office (VHO) will cache a subset of the Video Service Office (VSO) content. When a user requests content that is not stored on the VHO, the VHO will request that content from another VHO or the VSO.

A method and apparatus generates kinetic and electrical energy using sound waves and is believed to be particularly useful in high efficiency motors and electrical generators. In particular, the method and apparatus uses sound waves as a catalyst to convert ambient heat energy into kinetic and/or electrical energy.
