Abstract: Methods to extract oil from underground reservoirs are disclosed comprising pumping a gas comprising oxygen into the reservoir, causing combustion, and using the heat and pressure generated by the combustion to drive the oil through a well pipe to the surface. Systems for extracting oil from underground reservoirs are also disclosed comprising a gas compression system operable to pump oxygen from an oxygen source into the underground reservoir. The system has a supply pipe connected to the source of oxygen, a delivery pipe connected to the underground reservoir, a pump capable of pumping a liquid, a first tank with a first pipe and a second pipe, a second tank with a third and a fourth pipe and two pipe switchers operable to switch connections such that the tanks are swapped from a position between the supply pipe and the pump inlet and a position between the pump outlet and the delivery pipe.

Abstract: A pumping system is disclosed comprising a supply pipe, a delivery pipe, a pump capable of pumping a liquid, a first tank with a top port and a bottom port, a second tank with top port and a bottom port, a first pipe switcher operable to switch connections the supply/delivery pipes and the top ports, and a second pipe switcher operable to switch connections between the bottom ports and the pump inlet/outlet. The pipe switchers serve to switch input and output connections such that the tanks are swapped from a position between the supply pipe and the pump inlet and a position between the pump outlet and the delivery pipe. Uses for cooling systems, air compressors, deep wells, and oil extraction are also disclosed.

Abstract: A vertical axis windmill is disclosed which includes a set of frames attached via horizontal bars to a vertical axis of rotation, each frame comprising a plurality of swinging windows, each swinging window comprising an upper horizontal bar, vertical side bars, and a plurality of additional horizontal bars; a plurality of blinking sails comprising sheets of lightweight material, wherein the upper edge of each blinking sail is fixed at a horizontal bar, each blinking sail being allowed to move by pivoting or bending relative to the horizontal bar; a gap control rod for each of the frames, connected to each of the swinging windows in the frame such that all swinging windows in the frame move synchronously as the gap control rod is moved; and one or more electronically controlled actuators capable of moving the gap control rods.

Abstract: A DMC system integrates computerized systems, data storage systems, ATM machines, DMC machines and mobile phone systems capable of creating, selling and executing Digital Money Codes transactions to empower individuals to convert their cash into Digital Money Codes and to convert purchased Digital Money Codes to cash at different locations and empower people to send purchased Digital Money Codes to anywhere in the world so that they can convert the transmitted Digital Money Codes to cash at any time they want.

Abstract: A method for preventing unauthorized installation of application software is disclosed wherein application software is distributed with a user-readable permanent password, one or more user-readable one-time disposable password, and a hidden password (hidden from users but accessible by the setup program). When the setup program is run, the user must enter the permanent password and disposable password(s). The setup program sends these passwords and the target computer serial number to a remote server which verifies their validity, stores the serial number, and returns a complex password and a new disposable password from a remote passwords folder stored on the remote server. The setup program displays the new disposable password to the user who records it for use in future installations. The complex password is used to enable installation of the software, and it is deleted after installation is complete.

Abstract: A data storage device is disclosed with at least two partitions and a set of switches to separately enable and disable read and write operations to each of the partitions, wherein read and/or write operations for at least one of the partitions is disabled when the data storage device is accessible by one or more potentially malicious processes. In one embodiment, there are five partitions for (1) operating systems and trusted applications, (2) applications from non-trusted sources, (3) confidential data, (4) non-confidential data, and (5) all other data. A mode switch can be used to enable and disable reading and writing for each of the partitions according to a predetermined set of rules that effectively prevent viruses and other malware from altering or accessing programs and data.

Abstract: This invention protects the data on the hard disk from viruses and hackers by making it possible to turn off any head whether it is a read head or a write head of any arm of the hard disk by providing switches, so when we surf the Internet we turn off the read/write heads of the platter surface which contains the confidential data and we always turn off the write head of the platter surface which contains the Windows programs and other program files so the programs data are always protected and at the same time it is always readable, after we logoff the Internet we turn off the read/write heads of the platter surface used to save Internet data onto it thus we will never have any virus moving from this platter surface to the rest of the hard disk platters surfaces.
