This is a support device that prevents, reduces, and delays remodeling of diseased cardiac tissue, and also decreases the impact of such remodeling on collateral tissue is disclosed. The software also causes the processor to prioritize the caches having the common cache level such that the caches are displayable as having different cache levels. In some embodiments, the operating system is fully encapsulated on the portable storage device, such as the operating system being completely separate from an operating system initially booting the computing device. However, the database-informer can be customized and dynamically constructed based on various variables that are dynamically determined at runtime. In particular, the firearm locking system and method of the present invention provides a cylinder locking unit for a firearm adaptable to a firearm chamber, the cylinder locking unit including a receiver, an electric actuator, and a locking device extendible from the firearm chamber for preventing discharge of the firearm, the locking device extending upon activation of the electric actuator.
