Abstract: In a method of backup and recovery of file(s) and/or folder(s) stored on a non-volatile computer readable storage medium, a serial number of a recovery drive connected in operative communication with processor of a computer system, but not mounted to the operating system, is used to mount the recovery drive to the operating system. The processor copies file(s) and/or folder(s) stored on an internal drive to the recovery drive and then unmounts the recovery drive using the serial number. Following an encrypting ransomware attack, the same or another instance of the serial number of recovery drive is used to mount the recovery drive, whereafter the file(s) and/or folder(s) stored on the recovery drive are copied or restored to the internal drive. Finally, the recovery drive is unmounted using the serial number.

Abstract: A printed circuit biopotential sensing device is provided which is particularly adapted for endocardial or other deep body applications. The device has a predetermined printed circuit pattern formed on a thin film substrate, the pattern having at least one electrode pad at its distal end, at least one terminal pad at the proximal end, and conductor means selectively interconnecting the electrode pads and terminal pads. The substrate is secured to, and is preferably wrapped around an elongated member which is preferably tube-shaped in a manner such that the electrodes are exposed at the distal end of the member, and the terminal pads at the proximal end of the substrate are utilized in forming a suitable connector from the device.

Abstract: A dual compartment sandwich package fabricated of foamed polystyrene or the like and adapted to retain therein in appealing and acceptable form a sandwich including a hot meat portion, such as a hamburger, and a cool trimmings portion, such as lettuce and tomato. The package includes a base and cover having central rib means for rigidifying the package and preventing bending about the longitudinal and transverse axes thereof. There are four cooperating slots and tabs for temporary or secure locking of the cover to the base, which latter condition also forms an external seal to prevent heat exchange with the ambient atmosphere, while the central rib means form an internal barrier to prevent transfer of air and heat between the two compartments. A method of packaging a hot meat portion-cool trimmings portion sandwich, such as a lettuce and tomato hamburger sandwich for dispensing and final assembly by a customer in such a dual compartment package is also disclosed.
