Title: Dispersion compensation module
Inventor: KEYS CURTIS
IPC: H04B10/18
Filed: 2000-04-17
Abstract: Consistent with the present invention, a dispersion compensation module is provided which comprises a housing accommodating one or more spools of DCF. Each spool is provided in a respective package, which can be slidably insert ed into or removed from the housing along a track provided within the housing. "Jumpers" or relatively short pieces of fiber can be used to interconnect th e spools through adapters external to the packages. As a result, spools of DCF  can be readily coupled to one another to provide a desired amount of dispersion compensation. Moreover, the adapters are geometrically configured  so that connections can be made to the spools without excessively bending fiber interconnecting the DCF and the DCF itself, while permitting the modul e to conform to fiber optic packaging standards.

Inventor: WINNER KARL
IPC: G01S13/91
Filed: 2001-05-09
Abstract: A ground-based, precision aircraft landing system provides CAT I precision approach and landing guidance. The aircraft elevation position is determined by measuring differential carrier phase and time-of-arrival of the aircraft ATCRBS transponder reply. The transponder reply is received at a plurality of sensor antenna locations where it is then conveyed to a sensor, demodulated and digitized. The data is transmitted to a central processor where calibration and multipath corrections are applied. Aircraft transponder diversity antenna switching is isolated from the jitter and colored noise of transponder reply multipath by correlating differential phase jumps measured between separate sensor antennas. An estimate of the diversity antenna separation is maintained by Kalman filter processing; the estimated separation is used to correct the differential phase measurement data of aircraft elevation. The corrected phase measurement and time-of-arrival measurement is processed using another Kalman filter to achieve the desired aircraft elevation positioning accuracy. A similar differential carrier phase and time-of-arrival subsystem is applied to achieve an azimuth measurement of the aircraft position. The combined azimuth and elevation of the aircraft is then compared to the desired approach path, and the aircraft position error relative to the desired approach is communicated to the aircraft.

Inventor: WHITEHEAD LORNE A
IPC: G02F1/167
Filed: 2001-05-23
Abstract: A display for viewing images in a preferred direction (26). Parallel, macroscopically planar, structured surface, non-light absorptive light deflecting and reflecting portions are longitudinally symmetrical in mutually perpendicular directions (24, 20) which are perpendicular to direction (26). A  liquid (28) containing members (34) contacts the reflecting portion. A  controller (56) applies an electromagnetic force to selectively move the members into an evanescent wave region adjacent the reflecting portion, frustrating TIR at selected points on the reflecting portion. The deflecting portion's structured surfaces deflect (42) light rays incident (40) in direction (26) toward the reflecting portion by imparting to the rays a directional component in the reflecting portion's direction of longitudinal symmetry. The reflecting portion's structured surfaces totally internally reflect (44, 48) the deflected rays toward the deflecting portion wherever TIR  is not frustrated. The deflecting portion's structured surfaces deflect (50) the TIR'd rays, cancelling the directional component, such that the deflected TIR'd rays emerge (51) substantially parallel to direction (26).

Abstract: A method is provided for determining the integrity of incoming target data and for assigning and displaying a target icon correlated to the target data integrity. Target data integrity depends on the both accuracy and the timeliness of the position data being broadcast about the target. Target data integrity is monitored continuously to display a target icon correlated to the current integrity level. Changes in the target icon alert the flight crew or other user to changes in target data integrity. The icon attributes used to communicate a change in integrity do not interfere with other icon attributes used to communicate other characteristics of a target.
