The presently disclosed embodiments relate generally to layers that are useful in imaging apparatus members and components, for use in electrostatographic, including digital, apparatuses. The battery assembly comprises an energy cell powering a signal generation assembly of the instruments. The first seal ring is disposed in the IC. The device has one or more policy files defining policies for interaction of processes with the kernel of the device, and a monitor configured to monitor interaction of a process with the kernel to link or associate defined policies to the process, and to read code defined in the policy file or files linked or associated to the process.
