    Abstract: A scan assembly of an image generator sweeps an image beam in a first dimension at a first rate and bi-directionally in a second dimension at a slower rate. Sweeping the beam bi-directionally in the vertical dimension (generally the dimension of the lower sweep rate) can reduce the scanning power by eliminating the flyback period, and, where the scan assembly includes a mechanical reflector, can reduce the error in the beam position without a feedback loop by reducing the number of harmonics in the vertical sweep function. Furthermore, because the image beam is “on” longer due to the elimination of the flyback period, the scanned image is often brighter for a given beam intensity. The scan assembly may also sweep the image beam non-linearly in the vertical dimension, and this sweep may be bi-directional or uni-directional. Sweeping the beam non-linearly can also reduce the error in the beam position by reducing the number of harmonics in the vertical sweep function.

    Abstract: This invention generally relates to computer systems and architectures, methods and computer program code for increasing the robustness of process control and manufacturing automation systems and the like, in particular to provide improved handling of error and/or failure conditions. We describe an architecture for an OPC Failover system, the architecture comprising: a plurality of OPC servers; at least one OPC client; a computer network linking said OPC servers and said OPC client; and an OPC Failover service coupled to said network and not coupled between said OPC client and said OPC servers, said OPC Failover service being configured to monitor at least one of said OPC servers for an error condition and to redirect network communications of said OPC client from one of said servers to another on detection of said error condition.
