A fiber-based source for high-energy picosecond and nanosecond pulses is described. By minimizing nonlinear energy limitations in fiber amplifiers, pulse energies close to the damage threshold of optical fibers can be generated. The implementation of optimized seed sources in conjunction with amplifier chains comprising at least one nonlinear fiber amplifier allows for the generation of near bandwidth-limited high-energy picosecond pulses. Optimized seed sources for high-energy pulsed fiber amplifiers comprise semiconductor lasers as well as stretched mode locked fiber lasers. The maximization of the pulse energies obtainable from fiber amplifiers further allows for the generation of high-energy ultraviolet and IR pulses at high repetition rates.

A distributed file storage and communication system stores redundant copies of segments of a file on multiple remote storage units. The file to be stored is partitioned into multiple fragments, and each of the fragments is redundantly stored on multiple remote storage units. A file tracker is maintained that identifies where each fragment is stored. Providing the file tracker to another user allows the other user to access the file. To receive and/or retrieve the file, the system retrieves each fragment by attempting to download the fragment from one of the remote storage units identified in the file tracker for the fragment; if the selected remote storage unit is not available, another storage unit is selected for attempting the download. The selection of storage units to receive each fragment may be random or targeted, or a combination of both. Preferably, each fragment is encrypted, and the intended recipient is provided a key to decrypt the fragments.

In a cellular mobile telecommunications system the position of a mobile station can be estimated in terms of its bearing and range from a cell site. A multi-element direction finding antenna at the cell site receives signals from the mobile station and a receiver circuit estimates the bearing using the relative phase of signals received at different antenna elements and estimates the range by measuring round trip delay of signals to and from the mobile station. Motion of the mobile station can introduce errors into the bearing estimate due to frequency offset and frequency spread when element sampling is non-simultaneous. Compensation for these errors is introduced by using signal samples successively received at the same antenna element to estimate Doppler frequency offset and spread. It is necessary to ensure accurate calibration of the direction finding antenna and the receiver circuit. This is done by injecting calibration signals into the circuit near the antenna or into the antenna itself from a near field probe. Other aspects of calibration, such as antenna position, are calibrated using a remote beacon. A beacon emulating a mobile station but at a fixed, known location, or a beacon at an adjacent cell site may be used.
