20090067079 | DATA STORAGE DEVICE WITH SECURITY FEATURE - 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. | 03-12-2009 |
20090300772 | METHODS FOR PREVENTING SOFTWARE PIRACY - 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. Subsequent installation or re-installations, if authorized by the terms of the software license agreement, are performed using the same procedure, except that for each such installation, a new disposable password must be used. | 12-03-2009 |
20120045333 | BLINKING SAIL WINDMILL WITH SAFETY CONTROL - 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. The swinging windows stop the blinking sails from being blown to one side of the frames, where that one side is on the same side of each frame relative to the direction of rotation of the vertical axis windmill. The swinging windows are movable toward that same side of the frame such that there is a variable gap to allow part of the air to pass through in the downwind direction. The electronically controlled actuators can be programmed to respond to available sensors including sensors for wind speed, wind direction, swinging window position, and windmill power output. | 02-23-2012 |
20120099219 | SECURE DATA STORAGE DEVICE - 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. | 04-26-2012 |

20150136390 | EXTRACTING OIL FROM UNDERGROUND RESERVOIRS - 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. | 05-21-2015 |
