A federated system comprising a plurality of input/output circuit card assemblies and a Firewire or other daisy-chainable bus that provides low latency communication between a host computer and peripheral devices. A single circuit card assembly is used to interface to each peripheral device, and communication between the host computer and peripheral device may be made using a plurality of different communication protocols. The input/output circuit card assembly is daisy-chainable and incorporates circuitry that implements a bus constructed to Firewire (IEEE-1394) and other electrical specifications.

System for interfacing host computer to multiple peripheral devices

A wide field-of-view simulator heads-up display provides images to a user along an optical axis. A HUD CRT provides images of a predetermined design wavelength, while rear projection screen CRTs provide out-of-window scenery that does not contain the predetermined design wavelength. A curved holographic combiner is mounted on the optical axis with a reflective hologram on a concave surface covered with a urethane overcoat. The convex surface has an antireflective coating. A tilted beamsplitter cooperates with a folding mirror in a relay optical system for providing a virtual image of the HUD CRT for reflection from the holographic combiner.
