Abstract: Devices and methods for transitioning between power states of a device are provided. A program is executed using data stored in configuration registers assigned to a component of a device. For a first reduced power state, data of a first portion of the configuration registers is saved to the memory using a first set of linear address space. For a second reduced power state, data of a second portion of the configuration registers is saved to the memory using a second set of linear address space and data of a third portion of the configuration registers is saved to the memory using a third set of linear address space.

Abstract: Methods and apparatus for laying fluid distribution lines along a surface are disclosed. An overhead support cable is secured between a plurality of anchoring devices spaced along the surface. A rotatable installation reel is then coupled to the overhead support cable and a coil of fluid distribution line is loaded on the installation reel. Fluid distribution line is laid along the surface by moving the installation reel along the overhead support cable so as to rotate the installation reel to pay out the fluid distribution line along the surface. Subsequent fluid distribution lines may be laid at substantially equal lateral spacings by moving each anchoring device or a portion of each anchoring device prior to laying each subsequent fluid distribution line.
