A dual-supply voltage latch includes a data input node to receive an input data, internal nodes to hold the input data, and an output node to output an output data. The HDD generates a random number, encrypts it with a key known to the PVR, and sends it to the PVR, which decrypts the number and increments it by one to render a new number. The invention further relates to a process for preparing the adhesive composition and to the use thereof for adhering wallpaper or billposter to a substrate. By controlling the gas flow rate through the pores, along with the process conditions and deposition rate of the thin-film electrode material, a film of a pre-determined thickness can be formed. The collapsible tube may preferably include an external thread form on a flexible throat coupled to a flexible shoulder.
