Title: Attitude determination utilizing an inertial measurement unit and a plurality of satellite transmitters
Inventor: BUCHLER ROBERT J
IPC: G01S19/48
Filed: 1997-12-30
Abstract: The invention is a method for obtaining observables for input to a Kalman filter process which determines the attitude (roll, pitch, and heading) of a platform. The invention utilizes an inertial measurement unit (IMU) attached to the platform and an associated processor, a plurality of signal receiving antennas attached to the platform, and a plurality of satellite transmitters. The heading of the platform as determined by the IMU and its associated processor by themselves can be significantly in error. A comparison of the values of an attitude-sensitive function of the ranges from the platform antennas to different groupings of satellite transmitters obtained first by using IMU data and second by using the measured phases of the satellite-transmitter signals received at the platform antennas, a very accurate value for the range function is obtained. This accurate value of the range function is used in a Kalman filter process to obtain very accurate values for platform attitude.

Inventor: BENVENISTE VICTOR M
IPC: C23C14/48
Filed: 1998-04-24
Abstract: An electrostatic triode lens (36) is provided for use in an ion implantation system (10). The lens includes a terminal electrode (37) and an adjustable! lens subassembly (40) comprising a suppression electrode (38) and a resolving electrode (39), each having matched curved surfaces (108,110). The lens subassembly is positioned near the terminal electrode where the beam has a minimal waist in a first (dispersive) plane. Such positioning minimizes the required gaps between electrodes, and thus, helps minimize beam blow-up and the electron depletion region in the deceleration mode of operation. The suppression and resolving electrodes each have first and second portions (38A and 38B, 39A and 39B) separated by a gap (d38, d39). A movement mechanism (60, 62) simultaneously moves the first portions of the suppression and resolving electrodes (38A, 39A.) toward and away from the second portions of the suppression and resolving electrodes (38B, 39B), respectively, to adjust the gaps (d38, d39) therebetween. The adjustable lens subassembly (40) conditions the beam output by the terminal electrode (37) by (i) variably focusing the beam in mutually orthogonal (dispersive and non-dispersive) planes in a deceleration mode of operation (where mass resolution is less critical), while (ii) permitting variable mass resolution in the dispersive plane in an acceleration mode of operation (where focusing is less critical). Generally, the gap (d39) between the resolving electrode pair (39) is adjusted to permit adjustable mass resolution in the dispersive plane in the acceleration mode of operation. In the deceleration mode of operation, adjustment of the gap (d39) provides adjustable dispersive plane focusing, while the voltage on suppression electrode (38) is adjusted to permit adjustable non-dispersive plane beam focusing.
