A parachutist navigation system includes a display attached to a side vision area of a parachutist's goggles, a navigation pod attached to the parachutist's helmet, and a remotely located controller. The navigation pod supports therein a GPS receiver and a processor provided with mission data supplied by the controller. The processor uses the mission data and GPS signals to generate a plurality of display-formatted data sets. Coupled to the processor is an user-controlled input device used to select at least one of the plurality of display-formatted data sets for output to the display.

Methods and systems for presenting images to vehicle occupants are disclosed. A system in accordance with one embodiment of the invention includes at least one display portion configured to display an image and be positioned proximate to a seat location within the vehicle. A first signal receiving portion can be configured to receive an input image signal, and a second signal receiving portion can be configured to receive a motion signal corresponding to a motion of the vehicle. A processing portion can be configured to direct to the at least one display portion a time-varying output signal that appears to move by less than an object actually positioned external to the vehicle would appear to move to an occupant at the seat location of the vehicle. Accordingly, the viewer may be less susceptible to motion sickness by receiving visual cues that correspond to less motion than the occupant feels.

A server including a cooling fan assembly and an input/output assembly at opposite ends of the server, and a processor assembly located between the cooling fan assembly and input/output assembly. The server also includes a cover plate that covers the processor assembly and cooling fan assembly and that has a power supply on the face of the cover plate facing the processor assembly and is electrically connected to the processor assembly.

Methods and systems for processing images corresponding to views external to a vehicle are disclosed. A system in accordance with one embodiment of the invention includes first and second signal receiving portions configured to receive a signal corresponding to an image of a view external to the vehicle and a speed of the vehicle, respectively. A signal processing portion can direct to a first display portion a first signal corresponding to the image and to a second display portion a second signal corresponding to the image, with the first and second display portions positioned at different locations of the vehicle. The second signal can be delayed by a time that corresponds at least approximately inversely to the speed of the vehicle. Accordingly, a viewer seeing both display portions can receive a visual indication that the vehicle is moving.

Systems and methods for presenting images in a vehicle as the vehicle rotates about a rotation axis are disclosed. In one embodiment, the system includes a signal receiving portion that receives a first signal corresponding to an image of a first view from a position located a first distance from the rotation axis. A signal processing portion directs to a signal display portion located a second distance from the rotation axis, a time varying second signal that represents a second view. The second view can be a portion of the first view and can occupy an area less than the area occupied by the first view. The location of the second area relative to the first area can be selected based at least on an amount by which the first and second distances differ.
