A combination current sensor and relay has an improved housing. The tool can include one or more blades extending outwardly or downwardly from the tool for cutting a metal item such as the wall of a casing string, or for removing a predetermined length of a casing string in a cutting action. The disk drive array is coupled to and distributed across the storage processor nodes and stores multiple titles. The source of RF power is configured to provide RF power and an RF feed configured to radiate the RF power from the RF source into the lamp body. The out-of-band communications are different from the service discovery protocols of the local network. Various embodiments in different sleeping and sitting environments are described.
