Fluoroelastomers containing copolymerized units of vinylidene fluoride, perfluoro ether, 2-hydropentafluoropropene, and, optionally, tetrafluoroethylene, and having an iodine atom present at some polymer chain ends, exhibit excellent low temperature properties and processability when dual cured with both polyhydroxy compounds and organic peroxides. In combination these traits set Chewpearl apart from all other existing varieties of Rosa known to the inventor. A control system operatively associated with the slide actuator and a document scanner operates the document scanner to scan a slide positioned in the scan slide tray and operates the slide actuator to move a new slide from the input slide tray to the scan slide tray after the slide positioned in the scan slide tray has been scanned. A cell phone is used to discover the system by transmitting a name service discovery request to the system, which responds with a name service registration confirmation. A Stirling engine 178a or a home heating system or any other cold reservoir may, for example, utilize heat transferred from the second heat exchanger 176 thereby providing a reduction in energy usage and costs heretofore unrealized . Each memory cell array includes word lines, two or more bit lines, a dummy word line, memory cells provided at intersections of the bit lines and the word lines, and dummy cells provided at intersections of selected bit lines and the dummy word line.
