An optical system includes a reference projector that projects collimated beams of light into the optical system entrance aperture which are imaged by an image recording device. The beams produce fiducial images present in every image captured by the imaging recording device. The fiducial images can be used to characterize the performance of the optical system and derive distortion correction coefficients. The distortion correction coefficients can be applied to a portion of an image, such as a group of pixels, or to the entire image, to thereby compensate for distortions in the optical system. In some embodiments, e. g. , airborne cameras, the projector is rigidly coupled to an inertial measurement unit. The ability of the airborne camera to perform object geolocation from imagery is improved. The fiducial images enable optical system performance to be characterized and distortion correction coefficients to be obtained and thereby improve the accuracy of a ray angle calculation to the object of interest.

A telecommunications pair gain system for use when all lines served by the pair gain system are within a limited distance of the pair gain system remote terminal. The distance is such that a lower voltage output from the remote terminal can be used for powering the POTS telephones. Advantageously, a single remote terminal can be used for controlling, for example, 8 POTS lines, at significantly lower expense than would be incurred using standard subscriber loop carrier technology. Advantageously, the loops no longer required for serving all of the 8 POTS lines directly, can be utilized to provide services such as Digital Subscriber Line (DSL) service to other customers without requiring the installation of additional loops between the central office and the remote terminal.

A system and method for restoring an operating N module redundant NMR) processors when one or more processors is in an out-of-service state. This NMR system comprises N processors each having an individual memory system. An interconnection network is configured to receive data from all N processors, and N voters are connected between the interconnection network and each of the N processors to receive data from the interconnection network and vote on data destined for the N processors. Writes of data from the active processors are rerouted to the interconnection network. Advantageously, there are registers in the interconnection network corresponding to each processor. These registers receive the data from their corresponding processors, and then send the data to all of the voters. The data is voted on and sent to all N processors. Thus, the memories of the out-of-service processors are restored with the active processors while the active processors continue to operate.

A duplex controller with a pair of redundant processor circuits connected by an update bus for use in a system which requires high reliability. Each of the redundant processor circuits is individually capable of performing the tasks of the duplex controller, so that the controller remains operable when one of the processor circuit members fails. The update bus is connected so that when the active circuit member executes a write command, the write command is also effected at the standby circuit. In this manner the memory state of the standby is dynamically maintained so that when control of the duplex controller is transferred from the active to the standby to the standby circuit, the standby circuit is instantaneously ready with up to date information to assume all processing responsibilities of the duplex controller without unnecessary delay.
