An apparatus and method for controlling the communication frequencies of a software controlled radio by using GPS to calibrate one or more local oscillators and compensating within the digital radio processing for the local oscillator inaccuracies. The apparatus and method receives and transmits radio frequency signals and includes an oscillator; a frequency monitor adapted to measure the frequency of the oscillator; a numerically controlled oscillator; and a computer adapted to receive the frequency measurement of the oscillator from the frequency monitor, to calculate an error associated with the oscillator, and to calculate a numerically controlled oscillator setting based on the calculation of the error associated with the oscillator; the numerically controlled oscillator adapted to receive the numerically controlled oscillator setting from the computer.

A system and method for rotating a source image by a first non-zero angle is provided. The method includes: defining a template for the source image, the template representing a rotation of the source image about an axis of the source image by second angle, where the second angle is the negative of the first non-zero angle; determining overlap between the template and the source image; separating the template into a plurality of strips covering at least the area of overlap; and for each strip: indentifying an initial pixel in the source image within the strip and storing the image data of the initial pixel; storing the image data of all remaining pixels within both the strip and the overlap in a database format in which the all remaining pixels is defined by a Y and X offset from the initial pixel.

An apparatus and method for using GPS uses a radiation tolerant executive module to monitor and reinitialize a GPS module. The GPS module can reload information from a radiation tolerant memory when it is reinitialized. The radiation tolerant executive module also can direct a first GPS module having a first clock generator and a second GPS module having a second clock generator to use a clock signal from one of the first clock generator and the second clock generator. The radiation tolerant executive module also may be used to direct a first GPS module having a first clock generator and a second GPS module having a second clock generator to phase lock the first clock generator to the second clock generator.

A pouch arrangement includes a distribution aperture arrangement in a gusset member. The gusset member is covered with a removable cover. A zipper closure selectively exposes and closes the gusset member. At an opposite end, a handle arrangement is provided. The pouch construction may be filled with a flowable material through an opening adjacent to the handle arrangement with the zipper unengaged and the gusset expanded and covered by the removable cover. A seal can be applied between the handle arrangement and the gusset to close the opening. The filled pouch is then displayable by resting it on the expanded gusset, with the zipper closure unengaged and the distribution aperture arrangement covered by the removable cover. In use, the removable cover is removed to expose the distribution aperture arrangement. Flowable material is allowed to pass through the distribution aperture arrangement in the gusset. After use, the gusset end of the pouch is closed by engaging the zipper closure.

A non-intrusive power control for a fault tolerant computer system which uses redundant voting at the hardware clock level. The computer includes three or more commercial central processing units (CPUs) operating synchronously. Outputs to system memory and system bus are voted by a radiation tolerant gate array which may be implemented in a custom integrated circuit. An interface control coupled to the voter can remove or connect power from a CPU and adjust CPU inputs, preventing damage to the components without terminating an operating program. The inputs and outputs at each write to and read from system memory are voted at each CPU clock cycle. A vote status and control circuit "reads" the status of the vote and controls the state of the CPUs using hardware and software. The system logic selects the best chance of recovering from a detected fault by re-synchronizing all CPUs, powering down a faulty CPU, or switching to a spare computer, resetting and re-booting the substituted CPU.

A computer system uses redundant voting at the hardware clock level to detect and to correct single event upsets (SEU) and other random failures. In one preferred embodiment, the computer includes four or more commercial processing units (CPUs) operating in strict "lock-step" and whose outputs (33, 37) to system memory and system bus are voted by a gate array which may be implemented in a custom integrated circuit. A custom memory controller interfaces to the system memory and system bus. The data and address (35, 37) at each write to and read from memory within the computer are voted at each CPU clock cycle. A vote status and control circuit "reads" the status of the vote and controls the state of the CPUs using hardware and software. The majority voted signals are used by the agreeing CPUs 32 to continue processing operations without interruption. The system logic selects the best chance of recovering from a detected fault by re-synchronizing all CPUs, powering down a faulty CPU or switching to a spare computer, resetting and re-booting the substituted CPUs.
