Abstract: Embodiments of the present disclosure disclose a method for navigating between a plurality of user interface screens displayed on a display unit of a system. The method comprises sensing a touch pattern received from a user on a displayed user interface screen of the plurality of user interface screens of the system. Then, a touch force, duration and location of the touch pattern are determined. The system performs at least one of replacing the displayed user interface screen with a user interface screen from among the plurality of user interface screens stacked subsequent to the displayed user interface screen. The system performs merging one or more elements of the plurality of user interface screens with one or more displayed elements of the displayed user interface screen. The system performs toggling sequentially between each of the plurality of user interface screens.

Abstract: In one embodiment a controller comprises logic configured to receive a document copy, wherein the document copy comprises an identifier which uniquely identifies an electronic device and an authentication algorithm logic, generate, with the authentication algorithm logic, a security key for the document copy based on at least one input from the user, transmit the security key to a remote device, and store the document copy and a computer-readable code which uniquely associates the document with the electronic device in a memory. Other embodiments may be described.

Abstract: A freeze dryer processes bulk powder products. The freeze dryer freezes the product by mixing an atomized spray of product with sterile liquid nitrogen. The resultant powder is freeze dried in a vessel, and the vessel contents is agitated to maintain product contact with heated vessel wall and to prevent agglomeration.
