Abstract: A computer readable storage medium has instructions that, when executed by a host computer cause the host computer to perform a method of write protecting the storage medium and therefore preventing a non-registered user from changing the permissions log file. The instructions include: writing copies of control files of the host computer into the protected memory, writing a copy of a user permissions log file of the host computer into the protected memory, and changing a startup execute path function of the host computer to initially read the copy of the user permissions log file in the protected memory; and opening a write controlling circuit path to prevent access to changing the permissions log file.

Abstract: A system and method for delivering electrical power-on-demand to at least one load circuit wherein the system operates primarily with reactive power. The method includes inductively coupling power from a source in a primary circuit to one or more load circuits. The system is arranged to store magnetic energy in a core surrounded by planar coils positioned in parallel. The magnetic circuit is toroidal, symmetrical and circuitous. Magnetic energy is transferred between loads through the system. Back currents from the loads are able to be converted to magnetic field energy contributing to the total of stored energy available to the loads. Since the combined energy held in the system is primarily reactive, internal energy losses are small.

Abstract: A flux sharing magnetic circuit has a parallel arrangement of secondary flux loops with secondary windings to drive output loads. A shared pool of flux is provided by a primary winding. An AC driven primary delivers current to the secondary circuits to maintain a desired voltage or current to a load. One or more control windings control current in the parallel flux loops and thus control the power delivered to the loads.

Abstract: A flux sharing magnetic circuit has a parallel arrangement of secondary electromagnetic circuits with independent loads. An AC driven primary delivers current to the secondary circuits to maintain charge in their batteries. The batteries deliver DC current to the loads while secondary coils provide battery charging currents to maintain charge in the batteries. When current is not drawn by the battery or the load, flux is delivered to a flux pool in the magnetic circuit so that input AC power drain is reduced.

Abstract: A high speed, microcomputer based, Fibre Channel compatible and fault tolerant information processing and mass storage system especially suited for information servers and application servers. A unique and extremely versatile system architecture, including a dual loop arbitrated, Fibre Channel capable, multiple-fault tolerant, hot swappable mass storage disk array, permits combinations of servers and mass storage arrays which can be tailored for a wide variety of applications and which can be configured with emphasis on the system characteristics such as redundancy, speed, processing capability, storage capability, and the like, as desired. A unique backplane and/or midplane arrangement for connecting the system components allows for easy and, in most cases, on-line field upgrading and/or service and at the same time provides for the very effective cooling of components, particularly those such as disk drives which tend to produce a lot of heat.

Abstract: The present invention discloses system and method for delivery of software from a device to a host system, with the software enabling the host system to communicate with the device. The method of the present invention uses an electronic component/storage device associated with the device (or provides one if none exists), and configures the electronic component to comprise a file system and files that are native to operating system of the host, which the host system can recognize, access, and use automatically for initiating communications with the device.

Abstract: The present invention discloses a system and method for delivery of software payload from a peripheral device to a host system, with generally one component of the software payload enabling the host system to communicate with the peripheral device. The method of the present invention uses an electronic component/storage device associated with the peripheral device (or provides one if none exists), and configures the electronic component to comprise a file system (e.g., CDFS—Compact Disk File System) and files that are native to operating system of the host (e.g., AUTORUN.INF), which the host system can recognize, access, and use automatically for initiating communications with the peripheral device, and delivery of the software payload. When communication with the host is established, any program can be loaded from the peripheral device to the host because the peripheral device appears to the host system as a CD ROM with an AUTORUN. INF file.

Abstract: A method for checking a computer's operating system for corruption and for de-corrupting it takes the steps of: loading a copy of an original operating system onto a second partition on the main drive, adapting the copy of the original operating system to the existing hardware configuration, restarting the computer from the copy of the original operating system, comparing the existing operating system on the first partition with the copy of the original operating system on the second partition so as to detect corrupted portions of the existing operating system, overwriting each of the corrupted portions of the existing operating system with each corresponding portion of the copy of the original operating system, restarting the computer from the existing operating system and rendering the first partition on the main drive as active before restarting the computer.

Abstract: An OS module is plug compatible with a host computer preferably through its USB port. The module includes a data signal gate, a hardwire write control device, a first memory device, and a second memory device. The first memory device holds portions of an OS that are unchanged during startup and operation of the host computer, while the second memory device holds portions of the OS that may be changed during startup and operation of the host computer. These components are interconnected for data signal flow between the host computer and the second memory device through the data signal gate, while data signal flow from the computer for writing to the first memory device is functional only through the data signal gate and the write control device. The first memory device may be read without limitation.

Abstract: A removable drive is plug compatible with a host computer preferably through its USB port. The drive auto-launches upon insertion and runs read, write and execute functions on a resident file in the removable drive, tagging the control programs of the host computer that are responsible for these functions. The control programs are then copied to the removable drive and the path for these functions is changed to the removable drive. When the removable drive is right protected, the host computer is no longer a viable target for unauthorized access.
