Title: Sar/gps inertial method of range measurement
Inventor: SCHNEIDER ARTHUR J
IPC: G01S13/90
Filed: 1994-09-16
Granted: 1997-07-08
Abstract: A method that provides precise target location measurement using a synthetic aperture radar (SAR) system jointly with a global positioning inertial navigation system (GPS/INS) located on a moving aircraft. The SAR system provides a precise measurement of the round trip elapsed radar wave propagation time from the aircraft location to a selected pixel in a ground map that includes a portion of the target. The velocity of radar wave propagation is measured at the same time that the range time lapse to the designated SAR map pixel is measured. When combined with position and velocity information derived from the GPS/INS inertial navigation system, the radar wave propagation time is used to calculate the position of the target pixel in GPS/INS coordinates, thereby improving measurement accuracy. The method comprises flyingan aircraft containing GPS/INS and SAR systems along a predetermined flight path. The relative position and velocity of the aircraft along the flight path is accurately measured using the the global positioning system. A first SAR map is generated. A target pixel in the first SAR map that corresponds to the target is then designated. A minimum of two additional SAR maps are generated and the target pixel in each of the additional SAR maps is designated. The position of the target pixel relative to GPS/INS coordinates and the velocity of radar wave propagation to the target using aircraft position data derived from the global positioning system are then simultaneously measured. Finally, a more accurate position for the target pixel is calculated using the computed value for the radar wave propagation velocity.

Granted: 2001-01-02
Abstract: A method and apparatus for structural deflection control, as well as associated sequential controls that are based on new control laws. The apparatus of this invention is of relatively low cost and performs better than prior art devices. The essence of the invention is to adjust the dynamic parameters (mass, damping, stiffness coefficients of the structure and/or input forcing coefficients) adaptive to input dynamic loads, by using the new devices and the suggested control laws. In so doing, the structure performs an adaptive function to effectively counter tile effects induced by multi-directional external excitations. The required control power can be nil, or many times lower than prior art active control devices, and the effectiveness can be equivalent or even better than the current state-of-the-art active controls. The devices used by the apparatus of this invention can readily be manufactured for immediate application in structures, buildings and contents, and other constructed facilities.

Title: Method and apparatus for adaptive channel allocation with power control in a mobile communications system
Inventor: WALLSTEDT KENNETH
IPC: H04B7/005
Filed: 1996-03-20
Granted: 2005-08-23
Abstract: In a cellular communication system, a method and apparatus are provided for allocating a channel for use on a connection between a base station and a mobile station in a cell, without making measurements of downlink interference. Throughout the system, uplink and downlink power levels are regulated so that, within each cell, their sum changes by an amount whose magnitude is substantially equal to the magnitude of change in path gain between the mobile station and the base station in that cell, and which sum is opposite in sign to the amount of change in path gain. This power regulation scheme assures that there will be a strong correlation between system-wide measurements of uplink and downlink interferen ce. Therefore, with the power regulation scheme in place, each cell determines uplink carrier to interference (C/I) ratios for the free channels available for use in the cell and selects an acceptable free channel having a C/I value that is within a predetermined acceptable range. If uplink C/I on the acceptable free channel is greater than the uplink C/I value of a channel currently assigned to a connection, then an intra-cell handover is performed so that the connection will be reassigned to the acceptable free channel. This technique is useful for providing an adaptive channel allocation scheme to systems, such as analog cellular communications systems, in which downlink interference measurements cannot be made.
